Global Rooftop Solar PV market Size Study, by Deployment, by Technology, by Grid Type, by End-Use, and Regional Forecasts 2022-2032

Global Rooftop Solar PV market is valued at approximately USD 54.17 billion in 2023 and is anticipated to grow with a healthy growth rate of more than 5.8% over the forecast period 2024-2032. Rooftop solar systems are roof-mounted electrical setups that convert solar energy into electricity, addressing a building's energy demands within an existing distribution network, which can either be on-grid or off-grid. These compact systems vary in size based on the structure's scale and are primarily installed on the rooftops of residential and commercial buildings. Government policies, such as net metering and community solar, have been pivotal in promoting the adoption of solar technology in countries like the U.S., Spain, and France. According to the Solar Energy Industries Association (SEIA), these laws enable consumers to utilize solar energy for their electricity needs and sell the excess power. Community solar initiatives, where local solar facilities are shared by multiple subscribers, further bolster this trend, offering credit on electricity bills for the power produced.

China's solar cell industry has seen remarkable growth, with a 14% increase in 2022 compared to 2021, as reported by the China Photovoltaic Industry Association. By the end of 2022, the installed PV capacity surpassed 390 gigawatts, a significant jump from 253 gigawatts in 2020. The high population and rapid industrialization in countries like China and India have surged the demand for electricity from renewable resources. Government initiatives and investments in smart city infrastructure are also playing a critical role in the rooftop solar PV market's significance in these regions. India's 2024 rooftop solar policies emphasize sustainable energy adoption and economic empowerment. The Interim Budget 2024-25 reflects the government's commitment to providing free electricity to one crore households through rooftop solar installations, allowing households to receive up to 300 units of free electricity monthly and sell surplus power back to distribution companies. The substantial budget allocation and initiatives like the National Portal for Rooftop Solar and the Residential Rooftop Solar Program are expected to drive market growth.

High installation costs and the need for regular maintenance of roof-mounted solar panels present challenges for industry expansion. Additionally, the significant capital expenditures associated with solar installations, when compared to other emerging renewable technologies, limit market growth. The cost of deploying glass for solar panels further adds to the overall expense, hindering the deployment of PV systems during the forecast period. Moreover, solar energy is collected for specific periods and stored in expensive, large batteries requiring regular replacement.

The Paris Agreement, signed in 2016, aims to enhance the parties' ability to adapt to climate change effects, mobilize sufficient finance, and drive countries to report on climate-friendly initiatives regularly. This has prompted both developed and developing countries to mobilize funds for environmental initiatives, thereby minimizing global carbon emissions. Tax incentives and green subsidies introduced by governments to boost solar energy utilization are expected to offer growth opportunities for the rooftop solar PV market during the forecast period.

The key regions considered for the global rooftop solar PV market study include Asia Pacific, North America, Europe, Latin America, and Rest of the World. The Asia-Pacific segment dominated the global rooftop solar PV market, with significant use of solar energy in standalone systems and rural electrification in India and China. Rapid urbanization and industrial expansion, coupled with substantial government investments in R&D and technological innovation, are expected to propel demand. China's Zhejiang-based China southeast space frame group and EVA, a back sheet manufacturer of the first PV, have established a joint venture to develop building-integrated PV projects, expected to deploy up to 950 MW of BIPV systems over the next five years. North America is anticipated to witness significant growth during the forecast period, driven by policies such as net metering and community solar projects. The U.S., the second-largest energy consumer after China, is enforcing stringent environmental regulations and encouraging photovoltaic energy use to reduce carbon footprints. In 2022 and 2023, solar energy experienced substantial growth in the U.S., with a projected 45% of electric capacity additions in 2022 coming from solar, totaling 17 GW, expected to rise to 56% in 2023, reaching 31 GW. The U.S. solar industry is set to expand by a record 32 GW in 2023, representing a 52% growth compared to the previous year.
