Rooftop Solar EPC Market Size

Rooftop Solar EPC Market size was USD 122.3 billion in 2024 and is projected to reach USD 227.7 billion by 2037 expanding at a profitable CAGR of 4.9% during the forecast period, i.e., 2025-2037. In 2025, the industry size of rooftop solar EPC is estimated at USD 128.2 billion. The profitable growth curve of the global rooftop solar EPC market is attributed to rising focus on decentralized energy generation and growing demands for renewable energy solutions. The advancements in solar technology have made rooftop solar installations convenient and cost-effective, increasing adoptions across residential, commercial, and industrial sectors. The International Energy Agency (IEA) estimated the number of households relying on solar PV to grow from 25 million in 2022 to more than 100 million by 2030 in the Net Zero Emissions by 2050 scenario.

A major growth driver of the sector is the declining costs of photovoltaic (PV) panels that have led to greater accessibility of rooftop solar systems increasing demands for rooftop solar engineering, procurement, and construction (EPC). For instance, in June 2024, Our World in Data estimated solar PV costs to have reduced by 90% in the last decade. The global push for sustainable energy solutions benefits the robust growth of the rooftop solar EPC market as tax incentives and subsidies encourage market players to invest more in providing end-to-end solar energy services. Residential, commercial, and industrial end-users demand quality solar power solutions with minimal risk and quality assurance that boosts demand for solar EPC services. Additionally, a large-scale increase in solar PV manufacturing is poised to maintain a favorable growth curve of the sector in the future.

Regions such as Europe and Asia Pacific have abundant solar resources and growing demands for electricity positions the rooftop solar EPC market to benefit by leveraging sustainable energy solutions. Emerging economies globally are witnessing a sustained effort to harness solar power for energy solutions. For instance, in October 2024, a rooftop solar power plant was inaugurated at the Geological Survey of India Training Institute, Hyderabad marking a continued push to leverage renewable energy. Additionally, companies operating in the rooftop solar EPC sector can benefit from the growing scrutiny of corporate sustainability commitments, by offering end-to-end rooftop solar solutions to help businesses reduce carbon footprints. The global rooftop solar EPC market’s future will be shaped by continued technological advancements in energy storage systems and solar power equipment that can open new opportunities for energy security and grid independence.
