The global market for Solar Engineering, Procurement, and Construction (EPC) services is forecast to nearly triple in size over the next decade, driven by supportive government policies, declining technology costs, and increasing corporate demand for clean energy solutions, according to a new report published by Allied Market Research.
The Solar EPC market, which includes end-to-end services for solar project development, was valued at $0.4 trillion in 2024 and could reach $1.2 trillion by 2034, registering a Compound Annual Growth Rate (CAGR) of 11.9 percent over the forecast period from 2025 to 2034.
The findings underscore the solar sector’s expanding role in the global energy transition and its increasing maturity as a competitive power source. The growth projection is significant for the energy sector, as EPC firms are responsible for converting policy and financial commitments into operational solar assets, ranging from residential rooftop arrays to utility-scale farms.
The primary drivers of this substantial growth include global climate commitments, such as national net-zero targets, and an aggressive push for renewable energy capacity. Government policies, including incentives, subsidies, and ambitious renewable energy targets in countries like India, are lowering the financial barriers to solar project development, according to the research firm.
Technological advancements, particularly in solar panel efficiency, coupled with falling module costs, are also contributing to the market’s expansion. These factors are making large-scale solar installations more economically viable, enhancing their competitiveness against traditional energy sources.
The study segmented the market across technology, installation type, size, and end-use.
Regionally, the Asia-Pacific market is poised to maintain its dominance and is projected to register the highest CAGR of 12.3% percent during the forecast period. The region’s growth is supported by strong government policy frameworks, including incentives and feed-in tariffs in major economies like China, India, Japan, and Australia, paired with surging energy demand. States within India, such as Rajasthan and Gujarat, have emerged as key contributors to the nation’s overall solar capacity, highlighting local policy impact.
Despite the strong growth outlook, the Solar EPC market faces consistent challenges, primarily centered on regulatory and policy volatility. The report cited “regulatory uncertainty and policy inconsistencies” as a key restraint, noting that sudden changes in subsidy structures, import duties, or delays in land acquisition can disrupt project timelines and raise execution costs.
Additionally, the solar supply chain remains a point of vulnerability, largely due to a dependence on imports from a limited number of countries for critical components, particularly photovoltaic modules. Mitigating these risks, along with addressing a global shortage of skilled labor for project execution, will be crucial for the industry to realize the projected growth targets.
The forecast indicates that the solar energy sector’s reliance on specialized EPC services — which offer turnkey solutions for system design, component procurement, and installation — will continue to expand as projects become larger and more technically complex, cementing the EPC market’s critical position in the future energy landscape.
