Rooftop Solar PV Market Outlook:
Rooftop Solar PV Market size was over USD 62.93 billion in 2025 and is poised to exceed USD 113.77 billion by 2035, witnessing over 6.1% CAGR during the forecast period i.e., between 2026-2035. In the year 2026, the industry size of rooftop solar PV is evaluated at USD 66.38 billion.
Solar energy is one of the most efficient and eco-friendly sources of power available today. Unlike fossil fuels, solar energy does not produce greenhouse gas emissions or air pollutants, making it a crucial solution in combating climate change. By harnessing sunlight through photovoltaic panels, individuals and businesses can significantly reduce their carbon footprint while benefiting from a renewable and abundant energy source.
One of the key advantages of solar energy is its independence from nonrenewable resources. Once installed, solar panels generate electricity without requiring fuel or producing harmful products, ensuring a clean and sustainable energy supply. Additionally, the solar power system offers long-term economic benefits, including lower electricity bills and potential government incentives. A rooftop solar PV installation is a type of electrical installation setup used to meet the energy demand of a building within an existing distribution network.
The rooftop solar model plays a key role in helping distribution businesses lower peak-hour demand while reducing transmission and distribution losses associated with on-site electricity generation and consumption. This model is instrumental in avoiding the demand for costly investments in commercial transmission infrastructure. More importantly, it reduces the dependence on grid power and diesel generators by offering users a stable, long-term, and reliable source of energy.
The rooftop solar model demonstrates significant cost-effectiveness compared to commercial and industrial electricity, with tariff rates lowered up to 25%. Moreover, the residential sector also gets benefits from the rooftop solar concept, as it provides power directly to their building through the grid. This model not only ensures affordability but also provides long-term reliability and sustainability. Rooftop solar systems are highly versatile, capable of being erected in various places including the rooftops of commercial and residential buildings, parking lots, and other available spaces, using essential components such as inverters and monitoring equipment. Rooftop solar applications utilize capacities ranging from 1 watt to several GW both on and off the grid. This rising need for rooftop solar is largely driven by incentive programs such as feed-in tariffs for surplus power from self-consumption systems, tax credits, power purchase agreements, and technology-specific renewable portfolio standards and tenders.
