Is Solar Energy a Growing Industry?
The solar energy industry is witnessing significant growth, driven by technological advancements, increasing consumer demand, and supportive government policies in key markets. The statistics on solar clearly show the solar market is poised for further expansion.
Concentrated solar power may be years away, but the solar industry has averaged an annual growth rate of 24% over the last decade. From residential rooftop solar to complete solar power plants, the future of solar photovoltaic is still being defined.
As we embrace sustainable energy solutions, solar is becoming a mainstream power source, not just an alternative. As an MIT publication states, “The massive scale of the solar resource and its broad distribution globally are consistent with solar energy becoming an important source, perhaps the leading source, of electricity generation worldwide.” Key players are scaling up, and global solar capacity is consistently increasing.
This growth is reflected in rising market size, with solar adoption becoming more prevalent across various sectors worldwide.
Prior Growth 24%
The solar industry averaged 24% annual growth over the last decade.
Projected Growth $373.84 bn
Solar power market is projected to reach $373.84 billion by 2029.
How Fast Is the Solar Industry Growing?
Solar industry growth isn’t just steady; it’s accelerating at an impressive pace. Recent statistics reveal substantial increases in solar adoption, outpacing previous growth rates in some years.
Historical Trends
For decades, solar was a niche industry. But a confluence of technological advancements and increasing global focus on renewable energy has transformed power generation’s future.
2021 to 2026 and Beyond
The US set new records in 2025. The global solar power market is projected to grow from $234.86 billion in 2022 to $373.84 billion by 2029, at a CAGR of 6.9% in the forecast period. This surge is fueled by escalating demand for renewable energy as individuals and businesses recognize the urgency of transitioning to sustainable power.
However, 2025-2026 presents a more complex picture. Residential solar installations are projected to decline 18% year-over-year in 2026 due to the expiration of residential tax credits. Utility-scale solar remains stronger, with 2026 projections increased by 9% to 36.1 GW.
Obstacles to Growth
One threat to rapid US expansion is ongoing reliance on foreign solar equipment markets. While US developers have relied on lower-priced foreign photovoltaics, recent policy decisions placed tariffs on solar photovoltaics from Southeast Asian countries.
Additionally, in 2025, new legislation repealed many key tax credits from the Inflation Reduction Act. This creates near-term headwinds for residential solar while utility-scale projects starting construction before July 4, 2026 remain eligible for credits through 2030.
So despite strong adoption, the pace of solar market growth will depend on several factors yet to be determined.
What Are the Projections for the Solar Industry?
When we look to the immediate future of the solar market, the horizon shows both promise and challenges.
Authoritative bodies like the Solar Energy Industries Association (SEIA) and Wood Mackenzie offer projections for the coming years.
SEIA states, “Solar PV and wind additions are forecast to more than double by 2028 compared with 2022, continuously breaking records to reach almost 710 GW.”
Over the next five years, the industry is poised to see remarkable advancements in solar PV technology, increases in solar capacity, and deeper integration into the global energy mix. However, this path isn’t without challenges.
Issues including supply chain constraints, regulatory hurdles, and grid modernization needs present complex obstacles. Nevertheless, by 2035, solar has the potential to power 40% of all US electricity.
The opportunities for innovation, market development, and solar’s role in achieving a sustainable energy future are immense and continue driving the industry forward.
Potential Growth 40%
By 2035, solar has the potential to power 40% of all US electricity.
Solar vs. Hydroelectricity 14%
Solar power is projected to produce 14% more than hydroelectricity in 2024.
What Is the Solar Industry Outlook for 2026?
As we look ahead to 2026, the solar market’s prospects are complex and nuanced. Policy changes will significantly shape the industry landscape.
Policy Impact and Tax Credits
In 2025, new legislation repealed many key IRA tax credits, particularly the residential Section 25D credit expiring at year-end 2025. However, utility-scale projects qualify for credits if construction starts before July 4, 2026, with four years to come online.
This creates a bifurcated market. Residential solar faces headwinds. Utility-scale solar remains strong, with developers racing to meet construction-start deadlines.
Residential Solar Outlook
Residential solar installations are projected to fall 18% year-over-year in 2026 due to the expiration of residential tax credits. This decline reflects the policy shift but doesn’t necessarily indicate shrinking long-term demand.
Utility-Scale Solar Outlook
The 2026 outlook for utility-scale solar has been increased by 9% to 36.1 GW. These projects benefit from extended credit access and construction-start requirements that provide clarity for financing and scheduling.
Long-Term Trajectory
Despite near-term residential softness, cumulative US solar capacity is expected to nearly triple from 279 GWdc at year-end 2025 to 769 GWdc by 2036, with average annual additions exceeding 44 GWdc.
This long-term growth reflects strong underlying demand, technological improvements, and the industry’s essential role in the electricity grid’s future.
Consumer Demand
Solar expansion reflects growing confidence in government and the private sector regarding solar viability. The challenge ahead is accelerating solar deployment while navigating policy uncertainty.
Over 111 GWdc of large-scale solar projects are currently in various stages of construction or development, representing significant untapped potential.
Fueling growth is continued private investment. Companies continue building US manufacturing capacity. Microsoft plans to purchase 12 GWac of American-made solar panels over eight years, reflecting appetite in the US market for domestic solar systems.
Coupled with ongoing advancements in solar technology, these developments are expected to continue driving market growth and enhancing efficiency and accessibility of solar systems.
Together, these factors make 2026-2027 crucial years for the solar industry, marking a time of transition and significant technological progress.
The Role of Government Policies in Solar Industry Growth
Government policies play a pivotal role in shaping the solar market. Incentives and tax credits have been instrumental to solar adoption dating back to the Public Utilities Regulatory Act of 1978 (PURPA).
The Inflation Reduction Act marked a significant milestone in the U.S. solar industry. The IRA’s provisions were designed to make solar more affordable and accessible, accelerating the transition to renewable energy. However, in 2025, new legislation repealed many key provisions, particularly residential credits.
Current policy emphasizes utility-scale solar through extended deadlines for construction starts through mid-2026 and ongoing access to Production Tax Credits for qualifying projects.
These policies not only affect financial accessibility but also signal long-term market direction and investor confidence. This governmental support remains crucial for industry expansion, helping overcome economic barriers and accelerate the transition to sustainable energy.
