The Growth of Solar Energy in New Jersey (Beginnings to 2025)

New Jersey has transformed from a solar energy newcomer into a national leader over the past two decades. By 2024 the state surpassed 5 gigawatts (GW) of installed solar capacity – more than double its total from 2017 – and solar power now generates roughly 7–8% of New Jersey’s electricity. This growth was not accidental. It stemmed from forward-thinking state policies, innovative incentive programs, and rapid declines in solar costs. In this article, we trace New Jersey’s solar journey from its early beginnings through 2025, examining key policies and programs, installation trends across residential and commercial sectors, economic impacts, job creation, regulatory milestones, and what lies ahead for solar in the Garden State.

Early Beginnings and Policy Foundations (1999–2005)

New Jersey’s solar story began in the late 1990s with ambitious clean energy goals. In 1999, the state adopted one of the nation’s first Renewable Portfolio Standards (RPS), requiring utilities to obtain a portion of their electricity from renewable sources. The RPS established a solar “carve-out”, mandating that a specific percentage come from solar generation. This created an early market for solar power.

To support these targets, New Jersey launched the Clean Energy Program in 2003, funded by a societal benefits charge on utility bills. This program offered rebates and incentives to help residents and businesses afford solar photovoltaic (PV) systems. In parallel, New Jersey implemented one of the most favorable net metering policies in the country. By 2004, state regulations allowed even large customer-owned solar arrays to feed excess power to the grid and earn credits, up to an initial cap (which was later lifted). These early policies laid the groundwork for solar adoption by reducing financial barriers and guaranteeing solar owners fair compensation for their energy.

Actual solar installations were modest at first. In 2001, New Jersey had virtually no solar capacity (only 0.03 MW installed). But with new incentives, the numbers began to climb. Homeowners and businesses started taking advantage of rebates and net metering to put panels on rooftops. By 2005, New Jersey’s installed solar capacity had grown to about 14 MW – tiny in absolute terms, but a roughly 500-fold increase in just four years. These early projects proved the viability of solar in the state and built a nascent industry of installers and integrators.

Key early developments (1999–2005):

• 1999: Electric Discount and Energy Competition Act (EDECA) establishes RPS, including a dedicated solar requirement.
• 2003: NJ Clean Energy Program launches, providing rebates for solar installations.
• 2004: Introduction of Solar Renewable Energy Certificates (SRECs) as a market-based incentive to fulfill the RPS solar carve-out. Each SREC represents 1 MWh of solar generation that utilities can purchase to meet requirements.
• Net Metering: Early 2000s policies allow grid connection of customer-sited PV and credit solar owners for excess generation, spurring residential adoption. (Initial size limits of 2 MW per system were removed by 2010, effectively permitting unlimited net metering for any size project, as long as annual production does not exceed a site’s consumption.)

These foundational steps set New Jersey on a path to broader solar growth, even as solar technology at the time remained relatively expensive. By the mid-2000s, the stage was set for a solar boom driven by stronger incentives and falling costs.

The Solar Boom: SREC Era and Rapid Growth (2006–2012)

Around 2006, New Jersey’s solar market entered a phase of rapid growth, fueled by the innovative SREC program and increasing RPS targets. The Solar Renewable Energy Certificate (SREC) system, adopted in 2004, began to hit its stride in the late 2000s. Under this market-driven mechanism, solar system owners earned tradable certificates for every megawatt-hour of electricity their panels produced. Utilities, in turn, were required by the RPS to purchase a certain number of SRECs each year to meet the solar quota or pay a fine (the Solar Alternative Compliance Payment, which was set in the hundreds of dollars per MWh). This created a powerful financial incentive for solar development – essentially a market for solar attributes on top of net metering and federal tax credits.

The results were striking. New Jersey quickly became an early national leader in solar deployment. By 2010 the state installed over 100 MW of solar capacity in a single year, becoming only the second state (after California) to achieve that pace. Total cumulative installed capacity jumped from ~74 MW in 2008 to 252 MW by 2010. The following year (2011), capacity nearly tripled to about 700 MW in operation statewide. At one point in 2011, New Jersey even ranked as the #2 state in the U.S. for total solar capacity, second only to California.

Several factors drove this solar boom:

• Strong SREC Market: High demand for SRECs led to soaring prices during the boom years. In the late 2000s, New Jersey SREC prices at times exceeded $600 per MWh (e.g. trades up to $680/MWh), far eclipsing the value of the electricity itself. These prices translated into lucrative returns for solar project owners, attracting significant private investment. By one estimate, the state’s solar incentive structure was stimulating about $1 billion in investment annually in this period. However, the market-based approach also brought volatility – if solar installations surged faster than RPS requirements, SREC oversupply could cause price crashes (indeed, a brief SREC price collapse in 2012 underscored this risk).
• Net Metering & Tax Incentives: New Jersey’s unlimited net metering policy (fully in effect by 2010) meant even large commercial sites could install solar and effectively spin their meters backward to reduce bills. Additionally, New Jersey provided sales tax exemptions and property tax exclusions for solar installations, improving project economics. At the federal level, the 30% Solar Investment Tax Credit (ITC) further reduced the cost of systems during these years.
• Falling Technology Costs: The late 2000s and early 2010s saw significant declines in solar panel costs globally. New Jersey benefited from these trends. Solar installation prices in the state dropped steadily – by roughly 42% over the past decade according to industry data – allowing each RPS dollar or SREC to fund more capacity. Cheaper solar hardware enabled the industry to expand from niche applications to mainstream usage on homes, schools, and businesses.

By 2012, New Jersey had over 1,000 MW (1 GW) of solar installed statewide, an astonishing rise from virtually zero a decade prior. However, this breakneck growth also forced policy adjustments. In mid-2012, facing a looming oversupply of SRECs (and falling SREC prices), lawmakers enacted a so-called “solar rescue” bill. This legislation accelerated the RPS solar requirements – essentially pulling some later-year solar targets forward to soak up excess SRECs more quickly. The law (the Solar Act of 2012) also implemented measures to stabilize the SREC market, such as capping SREC prices (the Solar Alternative Compliance Payment was set at $325/MWh by 2014, effectively limiting SREC highs). Moreover, the Solar Act of 2012 opened new avenues for solar development: it created a program under subsection (t) to incentivize building solar arrays on landfills and brownfields, turning polluted lands into productive solar farms. This enabled projects like the 25 MW Mount Olive solar landfill and dozens of others, making New Jersey a leader in landfill solar reuse.

By the numbers (boom era): In 2011 alone, New Jersey installed 306 MW of solar (a 131% jump over the previous year’s additions). Cumulative capacity crossed 1 GW in 2012. Thousands of individual solar systems were deployed – from home rooftops in suburbs, to large commercial rooftop arrays on warehouses, to several utility-scale ground mounts. Significantly, the vast majority of installations were distributed (net-metered) projects. As of 2012, over 17,000 solar systems had been built statewide, and most of the capacity was on rooftops or customer sites meeting onsite demand. This set the stage for a more mature solar market entering the mid-2010s.

Market Maturation and Policy Transitions (2013–2021)

After 2012, New Jersey’s solar growth trajectory became steadier, as the market matured and policymakers refined incentive programs for long-term sustainability. The period from 2013 to 2021 was characterized by continued expansion in installed capacity, albeit at a more controlled pace than the early boom, and major transitions in state solar policy to move beyond the original SREC model.

By 2015, New Jersey had about 1.65 GW of solar installed, and this climbed to 2.41 GW by the end of 2017. The state consistently ranked among the top 5–10 states for solar capacity nationwide. While growth was robust, the annual installation rates fluctuated in response to incentive values. For example, after the 2012 SREC reforms, solar developers hit a cautious pause; then a record 453 MW was installed in 2019 as developers rushed to complete projects before certain incentive changes. This 2019 spike tied a previous record and demonstrated the market’s continued strength.

Several key policy and program developments shaped this era:

• Clean Energy Act of 2018: This landmark legislation overhauled New Jersey’s renewable energy goals and solar incentives. It raised the RPS targets to 35% renewable by 2025 and 50% by 2030, cementing New Jersey’s RPS as one of the most aggressive in the nation. The law also increased the solar carve-out and set in motion the phase-out of the legacy SREC program once a threshold (5.1% of electricity from solar) was met. In essence, it mandated a transition to a new incentive structure by mid-2021.
• Phasing Out SRECs: By 2018–2019, New Jersey’s regulators determined that the SREC program would close to new entrants by spring 2020 (when the 5.1% solar target was hit). The legacy SREC system had successfully driven over 3.3 GW of solar installations by that point, but concerns about cost to ratepayers and price volatility led to designing a replacement. To avoid a market gap, a Transition Incentive (TI) program launched in late 2019, offering fixed-price Transition Renewable Energy Certificates (TRECs) for projects until the new long-term scheme was ready. The TI program supported an additional ~987 MW of solar projects through mid-2021.
• Community Solar Pilot: Another milestone was the introduction of community solar. In 2018, legislation enabled a pilot program for community solar projects, which allow residents (especially those lacking suitable roof space) to subscribe to shares of a solar farm and receive bill credits. The Board of Public Utilities (NJBPU) launched Year 1 of the Community Solar Energy Pilot in 2019 and Year 2 in 2020, with a focus on including low-to-moderate income households. This pilot proved very popular – by 2021 the BPU had awarded 105 projects (totalling 165 MW) under Year 2 alone, and the first community solar arrays began delivering savings to subscribers. Community solar added a new dimension to New Jersey’s solar growth, aiming for more equitable access.
• Net Metering Cap Raised: Even as incentives shifted, net metering remained crucial. In 2018, the state doubled the net metering program cap from 2.9% to 5.8% of statewide electricity sales. This ensured that the growing volume of customer-sited solar could continue to net meter without hitting a ceiling. It was a proactive move to accommodate more distributed generation on the grid.

By the end of this period, New Jersey had smoothly navigated the “solar transition.” In July 2021, the NJBPU officially launched the new Successor Solar Incentive (SuSI) Program. This program was the culmination of a three-year stakeholder process (mandated by the 2018 Act) to craft incentives that would keep solar growing while controlling costs. The SuSI Program created a bifurcated approach:

• an Administratively Determined Incentive (ADI) with fixed incentives (termed “SREC-II”) for residential, most commercial, and community solar projects up to 5 MW, guaranteed for 15 years; and
• a Competitive Solar Incentive (CSI) using competitive bidding for larger projects and grid-scale solar.

The incentive levels under ADI were set significantly lower than old SRECs (e.g. $70–$120 per SREC-II depending on project type, vs. ~$220 average SREC value previously) – reflecting the lower cost of solar by 2021 – yet high enough to keep investment flowing. The SuSI Program aimed to enable an additional 3,750 MW of new solar by 2026, effectively doubling New Jersey’s solar capacity from the 2021 baseline. Notably, it included special adders: an extra $20/MWh for projects serving public entities (schools, municipalities) and temporary incentives for building solar on contaminated sites.

Installation trends: During 2013–2021, New Jersey’s solar mix started to diversify. While residential rooftops and commercial installations dominated (thanks to net metering and ADI-style incentives), the state also saw more utility-scale solar farms built on open land, especially after the Solar Act of 2012 facilitated projects on landfills and brownfields. By January 2024, New Jersey had 191 larger “grid-supply” solar projects feeding power directly to the grid (about 17% of total capacity). The other ~83% of capacity was still in distributed systems – tens of thousands of smaller arrays on homes, offices, schools, and warehouses. In fact, as of early 2024, over 194,000 individual PV installations existed across the state. This figure underscores how deeply solar has penetrated communities: from residential neighborhoods putting up a few kilowatts each to big-box retailers and corporate campuses offsetting their loads with multi-megawatt rooftop systems.

By 2021, cumulative solar capacity reached about 3.85 GW. New Jersey’s solar industry had weathered the transition period and was poised for another growth spurt under the new incentive regime.

Record Growth and Milestones (2022–2025)

The years 2022 through 2024 brought New Jersey’s solar development to new heights. With the Successor Incentive in place and pent-up project demand from the transition period, the state hit record installation numbers and achieved significant milestones:

• Record Installations in 2022: New Jersey added 455 MW of solar capacity in 2022 – the most ever in a single year. This edged out the previous high of 453 MW in 2019 and signaled strong post-pandemic momentum. Notably, over 18,000 new solar installations were completed in 2022 alone. Residential solar saw tremendous uptake as homeowners looked to save on energy bills, while commercial solar also had a banner year with more than 800 new commercial systems totaling 267 MW. Utility-scale projects and community solar farms contributed the rest. The NJBPU described 2022 as “a record year in the development of New Jersey’s solar market,” highlighting that installations were accelerating again.
• 5 GW Capacity Milestone: By the end of 2024, New Jersey officially surpassed 5 gigawatts of installed solar statewide. The Murphy Administration celebrated this achievement in January 2025 as a major clean energy milestone. For context, 5 GW of solar is enough to power roughly 940,000 homes (about a fifth of NJ households) and represented over 8% of New Jersey’s electricity generation in-state. The accomplishment is even more striking considering the state had just 2.4 GW in 2017 – the solar fleet more than doubled in seven years. There are now over 209,000 solar installations scattered across the Garden State’s rooftops and properties, from suburban residential systems to large commercial arrays and community solar farms.
• Community Solar Expansion: 2022 was also the first full year of New Jersey’s Community Solar Energy Pilot Program delivering results. Seven new community solar projects came online in 2022 (bringing the total to 21 operational projects) under the pilot, including the first projects from Year 2 of the program. These community solar installations are providing bill credits to more than 5,500 subscribers, many of whom are renters or low-income households that previously couldn’t go solar. Collectively, subscribers had saved over $1 million on energy bills by early 2023 thanks to the program. The BPU anticipated a major scale-up in 2023, with around 100 new community solar projects (150+ MW) expected to energize, half of the capacity reserved for low- to moderate-income participants. Plans were also underway to transition from the pilot to a permanent community solar program, reflecting its success.
• New Incentive Programs Operational: The Administratively Determined Incentive (ADI) component of the SuSI program proved popular in its first full year (2022). By January 2024, approximately 442 MW of solar projects had been completed under the ADI incentives (which cover residential, small commercial, and community solar). On the larger end, the BPU approved the design of the Competitive Solar Incentive (CSI) program in late 2022, and initial solicitations for grid-scale projects began in 2023. The first two CSI solicitations through 2024 awarded over 300 MW of large-scale solar capacity to be built in the coming years. Together, ADI and CSI are engineered to sustain an annual solar build-out of roughly 750 MW per year in New Jersey (as authorized by the Solar Act of 2021) – a significant ramp-up that will keep the state on track toward its clean energy targets.
• Executive Policy Momentum: Policy goals continued to rise. In early 2023, Governor Phil Murphy issued an Executive Order accelerating New Jersey’s long-term goal to 100% clean electricity by 2035, moving it up from 2050. Solar is expected to supply roughly one-third of that 100% clean power goal. This has further galvanized solar development, alongside investments in offshore wind and energy efficiency. Additionally, the state set a goal for 2,000 MW of energy storage by 2030, acknowledging the need to pair storage with solar for grid reliability (a storage incentive program is being designed as of 2023). The NJBPU also launched a Grid Modernization proceeding to streamline interconnections, upgrade distribution infrastructure, and enable higher penetrations of distributed energy including solar and batteries. These complementary efforts aim to ensure the electrical grid can handle the surging solar capacity in coming years.

By 2025, New Jersey’s solar landscape is one of broad participation and diversified growth. The state has large utility solar farms (over 90 installations above 5 MW each, totaling ~850 MW) and hundreds of medium-sized projects in the 1–5 MW range feeding the grid. But the lion’s share of capacity – about 80% – remains in net-metered systems on homes and businesses. This includes everything from residential rooftop panels to sizable commercial rooftop and carport arrays. Around 16% of capacity is utility-scale “grid supply” solar feeding wholesale power, and roughly 3–4% is community solar serving subscribers. This balance reflects New Jersey’s historically bottom-up solar growth, driven by individual customers and distributed generation. It also highlights the success of policies like net metering, which allowed thousands of smaller projects to flourish.

Economic Impacts: Investment, Costs, and Savings

The growth of solar energy in New Jersey has not only advanced clean energy goals, but also delivered significant economic benefits. Solar development has spurred billions in investment, created local jobs, and helped stabilize energy costs for consumers.

Investment and Market Size: Cumulatively, over $16.6 billion has been invested in New Jersey’s solar installations as of the mid-2020s. This figure encompasses residential systems, commercial projects, and utility-scale farms built over the last two decades. The industry continues to attract roughly $1 billion in new investment each year in the state during recent years – an impressive level of sustained capital inflow. These investments come from homeowners, businesses, solar developers, and financiers leveraging federal tax credits and state incentives. Importantly, most of this money is spent on local installers, construction labor, electrical equipment, and services, keeping dollars circulating in New Jersey’s economy.

Falling Costs: One driver of increasing investment (and adoption) is the sharply declining cost of solar technology. The average installed price of solar in New Jersey has fallen by approximately 42% in the past decade. In the early 2010s, residential solar often cost well above $4 per watt; today, economies of scale and global manufacturing have brought costs closer to the $2/W range (before incentives). This means consumers get much more solar capacity for the same expenditure than they did years ago. Cheaper solar panels and inverters, more efficient installation practices, and competitive financing (e.g. solar leases and power purchase agreements) have all contributed to making solar far more affordable. As a result, state incentives like SREC-IIs can be lower than past SREC prices yet still make projects financially attractive, saving ratepayers money in the long run.

Energy Cost Savings: Solar power has become a valuable tool for New Jersey residents and businesses to hedge against high electricity costs. New Jersey traditionally has above-average retail electricity rates (e.g. around 15–16¢/kWh for residential customers in 2016, which was 3¢/kWh higher than the U.S. average). By generating their own electricity, solar owners reduce the amount of power they must buy from the grid, directly lowering their utility bills. Excess generation in summer earns credits (via net metering) that can offset usage in other months, further increasing savings. Over the 25+ year lifespan of panels, a typical residential solar array can save tens of thousands of dollars on energy bills, especially as grid electricity prices tend to rise over time. On a larger scale, solar is contributing to downward pressure on wholesale electricity prices during peak demand periods (like hot summer afternoons) by adding supply to the grid when it’s needed, thereby improving price stability.

The state’s innovative programs also extend savings to those who can’t install their own panels. The community solar projects online so far have saved New Jersey subscribers over $1 million in aggregate on their energy bills as of early 2023, and those savings will grow as more projects come online. Additionally, low-income households stand to gain from dedicated solar funding: in 2024, New Jersey secured a $156 million federal grant (through the EPA Solar for All initiative) to build solar for disadvantaged communities, expected to result in $250 million in energy bill savings for around 22,000 low-income families over 30 years. These initiatives underscore the state’s focus on affordability and equity, ensuring the economic benefits of solar reach all residents.

Renewable Energy Certificates: Another economic aspect is the market for SRECs and successor RECs. While these are an incentive cost from one perspective (ultimately paid by ratepayers via RPS compliance), they have also provided a revenue stream to system owners. During the SREC era, homeowners and businesses with solar could earn hundreds to thousands of dollars per year by selling SRECs, significantly shortening the payback period of their investment. Even under the new programs, fixed incentives (SREC-IIs) continue to provide steady income to solar owners (e.g. $90/MWh for residential systems under ADI). This structure has made solar not just an environmental choice but a financially savvy investment for many New Jersey property owners, effectively lowering their long-term energy costs.

In summary, New Jersey’s solar expansion has funneled billions into the state economy, delivered energy savings to consumers, and helped diversify the state’s energy mix in ways that mitigate price volatility. Every dollar spent on a solar installation generates ongoing returns in the form of jobs, lower bills, or avoided fuel costs. As solar approaches grid parity, the need for incentives will diminish, but the economic benefits will continue to accrue – especially as the state pivots to cleaner energy instead of sending money out-of-state to import fossil fuels.

Job Creation and the Solar Workforce

The rise of solar energy in New Jersey has been accompanied by the growth of a vibrant clean energy workforce. Thousands of New Jerseyans now work in solar installation, sales, engineering, manufacturing, and related fields, contributing to the state’s economy while building a cleaner grid.

As of 2022, New Jersey had approximately 8,781 jobs in solar energy – one of the largest solar workforces of any state (11th in the nation by one ranking). These include “majority-time” solar workers across various sectors: rooftop PV installers, electricians, designers, project managers, sales representatives, maintenance technicians, and more. The solar industry’s presence in New Jersey is broad, with over 300 solar companies operating in the state (ranging from local installers to national developers) and projects in every county.

To put the growth in perspective, New Jersey’s solar employment was around 6,000 workers in 2016. By 2021 it was roughly 6,237 workers, and by the mid-2020s it had climbed to the 7,000–9,000 range. This steady growth in jobs parallels the cumulative build-out of solar capacity. Moreover, the state views clean energy as a jobs engine: “We are solidifying New Jersey as a magnet for green jobs,” said NJBPU President Fiordaliso in 2021 when approving the Successor Incentive program. Every megawatt of solar installed translates into numerous job-hours for site assessment, permitting, installation, grid connection, and ongoing operations.

Importantly, solar jobs in New Jersey are local and cannot be easily outsourced. When a homeowner installs panels, local crews do the work on-site. This contributes to skilled trade employment and small business growth. In fact, the top occupations benefiting from New Jersey’s green economy growth include electricians, plumbers, HVAC technicians, and solar installers, all of which are projected to see increasing demand. Many of these jobs provide solid, family-sustaining wages and do not require a college degree – installers, for example, often learn through apprenticeship and training programs.

New Jersey’s government has recognized the need to cultivate a workforce to meet the growing demand. The state’s Office of Climate Action and Green Economy released a Green Jobs Report 2025 highlighting plans to add 14,000+ new clean energy jobs by 2035 and identifying workforce training priorities. The report notes that stronger coordination between employers, educational institutions, and training providers will be key to filling positions like solar installer as the industry expands. Already, numerous training initiatives are in place. For example, the New Jersey Economic Development Authority (EDA) has funded Green Workforce Training Grants and apprenticeship programs focused on clean energy trades. Nonprofits and industry groups also offer solar training (some New Jersey solar firms partner with programs like Solar Ready Vets and community college certificate courses to recruit new talent).

Another aspect of job creation is the indirect and induced jobs stemming from solar. Building solar projects involves supply chains – some solar mounting equipment and components are supplied by local manufacturers and distributors, supporting additional employment. And the savings from solar can be spent in the local economy, creating a multiplier effect. A 2017 analysis noted that solar projects can create significant construction jobs (though temporary) – for instance, the 20 MW Pilesgrove solar farm built in 2015 created over 100 construction jobs on-site. While utility-scale farms have fewer long-term jobs once built, the ongoing operation and maintenance of tens of thousands of distributed systems supports a network of service jobs (for panel cleaning, system monitoring, inverter replacements, etc.).

By 2024, the solar industry’s footprint in New Jersey employment was substantial enough that the NJBPU President could say the sector “employs thousands of good, local jobs” and is a “vibrant part of our clean energy innovation economy.” In short, solar has become a mainstream employer. The continuing policy support for solar – aiming for hundreds of megawatts of new capacity each year – means that job opportunities are poised to grow further in installation, project development, grid integration, and manufacturing (especially with federal incentives potentially encouraging more domestic solar manufacturing).

New Jersey’s emphasis on workforce development, through EDA grants and labor partnerships, will help ensure the labor pool can meet the demand. The state is particularly focusing on training in underserved communities and engaging union apprenticeships to provide pathways into clean energy careers. This not only addresses equity in employment but also helps meet the industry’s needs for skilled labor. As one example, in 2024 the EDA launched an Apprenticeship Training Program making nearly $10 million available to support new training centers for the building trades with a clean energy focus.

In summary, solar energy has been a bright spot for New Jersey’s job market. The industry grew roughly 12% from 2021 to 2023 alone in terms of workforce, recovering from the pandemic dip and outpacing overall state job growth. Looking ahead, every step toward New Jersey’s clean energy goals (50% renewables by 2030, 100% clean power by 2035) will translate into more employment opportunities in solar and related fields. The state’s proactive planning aims to ensure its workforce is ready to seize those opportunities.

Regulatory and Utility Drivers of Growth

New Jersey’s solar ascent was not only a product of incentives and RPS percentages; it was also shaped by smart regulatory decisions and utility initiatives that facilitated solar integration. Several developments on this front deserve mention:

• Net Metering and Interconnection Rules: As discussed, New Jersey was a trailblazer in adopting broad net metering. By removing system size limits in 2010 and raising caps on aggregate participation, regulators ensured that virtually any customer could go solar and receive full credit for exports. The BPU’s adjustments (e.g. increasing the net metering cap to 5.8% of utility peak demand in 2018) prevented the program from stalling and signaled that New Jersey welcomed more distributed solar. Additionally, the BPU has been active in streamlining interconnection standards, especially with the Grid Modernization proceeding initiated in 2022. Proposed rule changes aim to simplify and expedite the process of hooking up solar systems to the local grid, and to enable technologies like smart inverters that help maintain grid stability. This regulatory support is crucial for solar developers to avoid long delays and high costs when connecting new projects.
• Utility-Led Solar Programs: New Jersey’s utilities have played a role in expanding solar, often in unique ways. A standout example is PSE&G’s “Solar 4 All” program, launched in 2009. This initiative by the state’s largest utility set out to install solar panels on 200,000 utility poles across its service territory. These pole-mounted solar units (each modest in size, but multiplying into a large fleet) added 38 MW of distributed generation – at one time the largest project of its kind in the world. In addition to the pole-mounted array, PSE&G built 34 larger solar installations (solar farms and rooftop systems) totaling 152 MW under Solar 4 All. These utility-driven projects helped jumpstart solar growth and utilized space like rooftops, brownfields, and landfills that might not have been developed otherwise. While not without controversy (ratepayer cost concerns), the program demonstrated how utilities could actively integrate solar into their infrastructure. Other utilities, like Atlantic City Electric and Jersey Central Power & Light, have mainly participated via interconnection of customer projects, but also facilitated pilot programs (for example, community solar projects require coordination with utilities for billing credits).
• Land Use and Siting Regulations: New Jersey’s regulators have also tackled the challenge of where to site solar as the industry grew. The Solar Act of 2012 provided clear rules for grid-supply projects on farmland versus disturbed lands, to balance development with preservation. By channeling large projects toward landfills, brownfields, and underutilized spaces (through subsection (t) of the law), the BPU enabled hundreds of megawatts of solar while minimizing impact on open green space. This regulatory approach turned potential land-use conflicts into an opportunity – New Jersey leads the nation in solar built on Superfund sites (17 projects, 187 MW as of 2023). The state also launched a dual-use solar pilot (agrivoltaics) in 2022, exploring how to allow solar installations on farms that continue to produce crops or grazing, demonstrating a flexible regulatory mindset to expand solar footprints without displacing agriculture.
• Protecting Consumers and Ensuring Equity: The BPU and Division of Consumer Affairs have kept an eye on the consumer protection side of the solar boom. As solar leasing and third-party ownership grew popular, the state implemented registration requirements for solar contractors and standards for marketing to prevent scams. On the equity front, regulators integrated equity considerations into program design (e.g. mandating at least 51% of community solar capacity serve low/moderate income customers in pilot projects). The Successor Incentive Program also created a higher incentive for community solar projects serving low-income customers. These measures ensure the regulatory framework not only boosts raw megawatts but also aligns with broader public interest goals.

In summary, supportive regulation and utility engagement have been linchpins in New Jersey’s solar rise. By making the grid “solar-friendly” through net metering and interconnection policies, and by encouraging innovative utility programs and sensible siting, the state smoothed the path for rapid adoption. The NJBPU’s continual oversight – from adjusting the SREC market to launching new incentives and addressing grid integration – gave the industry the stability needed to invest and grow. Moving forward, continued regulatory adaptability will be important, particularly as solar penetration increases and new challenges (like higher daytime backfeeding on distribution networks) emerge. So far, New Jersey’s regulators have shown a willingness to innovate in tandem with the industry.

Future Outlook: Solar in New Jersey Beyond 2025

Looking ahead, New Jersey’s solar journey is far from over. By 2025 the state has built a strong foundation, but even more ambitious targets loom on the horizon. The trajectory suggests continued growth, albeit with new challenges and opportunities to navigate in the push toward a cleaner and more distributed energy system. Here are some key trends and expectations for New Jersey solar beyond 2025:

• Steady Growth to Meet Clean Energy Goals: New Jersey’s policy goals virtually ensure that solar capacity will keep rising. The RPS (as updated in 2018) calls for 50% renewable electricity by 2030, and Governor Murphy’s executive actions target 100% clean power by 2035. Solar will supply a significant share of this. According to the state’s Energy Master Plan, solar could contribute around one-third of the electricity mix by 2035. Meeting these goals could require roughly 8–10 GW of solar capacity or more by 2035, up from ~5–6 GW in 2025. The current Successor Incentive Program authorizes about 750 MW of new solar per year; if that pace is sustained or increased with future program tweaks, New Jersey can hit those targets. In fact, industry observers note that simply continuing the current solar programs at their present rate would make solar “a key role” in achieving the 100% by 2035 goal. We can expect the BPU to monitor progress closely and adjust incentive levels or procurement volumes as needed to stay on track.
• Shift in Project Mix: While rooftop and behind-the-meter solar will remain significant (given New Jersey’s high population density and rooftop availability), the coming years may see a larger share of grid-scale and community solar projects. The pipeline for competitively bid projects is growing under the CSI program, and developers are eyeing bigger installations on capped landfills, warehouses, and open land (within environmental guidelines). Community solar is likely to become a permanent, scaled-up program, integrating lessons from the pilot to expand access to those who can’t put panels on their own roofs. Meanwhile, dual-use solar on farms (agrivoltaics) and floating solar on reservoirs are emerging concepts that New Jersey is exploring to expand capacity without consuming valuable land. These new project types, along with possibly larger solar farms in South Jersey’s rural areas, could contribute more significantly post-2025.
• Integration with Storage: As solar’s share of generation grows, pairing solar with battery storage will become increasingly important. New Jersey’s target of 2 GW of energy storage by 2030 is a clear signal of this need. We should expect many new solar projects to include storage components, allowing excess midday solar production to be stored for evening peaks. This is particularly relevant as the state retires more fossil fuel plants under its clean energy plan – solar+storage can help fill the gap and maintain grid reliability after sunset. The BPU’s forthcoming storage incentive program (likely rolled out by 2024–2025) will encourage solar developers to add batteries. By smoothing out solar’s variability and providing ancillary services to the grid, storage will enable even higher solar penetration. In the long run, a combination of distributed batteries (in homes and businesses) and utility-scale storage will help integrate the solar influx.
• Grid Modernization and EV Synergies: The grid upgrades initiated through the GridMod proceedings will need to materialize. Expect to see investments in advanced inverters, automated grid controls, and possibly community microgrids that can handle large amounts of distributed solar. Additionally, the rise of electric vehicles (EVs) in New Jersey (over 125,000 EVs registered as of 2023 and climbing fast) presents both a challenge and an opportunity for solar. EVs will increase electricity demand substantially, but they mostly charge at night – if managed smartly (with time-of-use rates or vehicle-to-grid tech), EVs could soak up daytime solar surplus or even discharge to support the grid, creating a symbiotic relationship between transportation electrification and solar deployment. By 2035, integrating EV charging load with solar generation could be a key strategy for balancing the grid.
• Continued Cost Declines and Innovation: Technological advancements will further shape the outlook. Solar panel efficiencies keep improving (new panels in the coming years will produce more power in the same amount of space), and costs may continue to inch down or stabilize at low levels. Innovations like bifacial panels (which capture sunlight on both sides), building-integrated PV, and solar-plus-storage virtual power plant models could all find a place in New Jersey. As the state’s solar market is relatively mature, it's also an ideal ground for next-generation business models – for instance, aggregated rooftop solar acting as a single power plant in grid transactions, or more sophisticated peer-to-peer energy trading using blockchain, etc. The regulatory environment post-2025 may gradually evolve to accommodate such innovations, especially as FERC and regional grid rules adapt to higher distributed energy resource (DER) penetration.
• Policy Certainty (and Uncertainty): One open question is how New Jersey’s policy framework might evolve after 2025. The current RPS solar requirements flatten out after 2025 in the statute (2.5% solar by 2028, for example, was an earlier goal), but the overall clean energy target effectively demands more solar beyond that. There has been discussion of moving from an RPS to a broader Clean Energy Standard or other mechanisms. In late 2023, a bill (S4300) was even proposed to eliminate New Jersey’s solar RPS requirements after mid-2025 in favor of new approaches. While the outcome is uncertain, any such change would be aimed at simplifying compliance or reducing ratepayer costs, not at curtailing solar development. The likely trajectory is continued support for solar, but possibly via more direct procurement (e.g. utility solicitations or inclusion in integrated resource plans) rather than fixed percentage carve-outs. Stakeholders will be watching how the Successor Incentive Program might be updated or extended beyond its initial 2026 scope – a process likely to begin by 2025 to ensure a smooth continuity for the solar industry. Federal policy will also play a role; the extensions of the 30% federal ITC through 2032 (enacted in the 2022 IRA law) give a stable backdrop for financing new projects in New Jersey for the rest of the decade.
• Challenges: Despite the optimistic outlook, challenges remain. Grid congestion in certain areas could slow interconnections if upgrades are not timely. Land availability in densely populated New Jersey is limited, so there may be tougher conversations ahead about using open space for large solar farms versus other land uses. Community acceptance can be a hurdle – some towns have resisted larger solar arrays due to aesthetic or land use concerns, requiring continued public engagement and smart siting (hence the focus on landfills and rooftops). Net metering compensation might evolve too: as solar grows, utilities and regulators might consider transitioning to time-varying rates or smart export management to ensure grid costs are fairly shared. The state will have to carefully balance solar growth with grid stability and equitable cost allocation. Thus far, New Jersey has managed this balance well, but the task will grow more complex at higher penetration levels.

Overall, the future for solar energy in New Jersey looks bright. The state has cultivated a strong ecosystem of policies, industry players, and public support. Solar is now a mainstream part of New Jersey’s energy landscape – providing local jobs, cleaner air, and a measure of energy independence. As we move beyond 2025, New Jersey is likely to remain at the forefront of solar deployment in the U.S., demonstrating how a densely populated, industrialized state can successfully pivot to a renewable energy economy. The journey from a few rooftop panels in the early 2000s to a future of ubiquitous solar powering every community is a testament to consistent policy leadership and grassroots adoption. If New Jersey continues on its current trajectory, solar power will be a cornerstone of its energy supply for decades to come, driving the state toward its climate goals while delivering economic benefits to its citizens.
