Rooftop Solar Panel Market to Grow from $41.2 Billion in 2025 to $78.5 Billion by 2035, Driven by Rising Distributed Adoption

Rooftop solar panel market was valued at $41.2 billion in 2025 and is projected to reach $78.5 billion by 2035, growing at a CAGR of 6.8% during the forecast period (2026-2035). Rooftop solar is emerging as a central driver of change in the global solar panel market, supported by the shift toward distributed energy systems and on-site power generation. Rising electricity costs, grid reliability concerns, and space constraints in urban areas are accelerating adoption across both household and corporate sectors. Corporate users, in particular, are using rooftop installations to manage long-term energy costs and meet internal sustainability targets, while households are increasingly adopting rooftop systems to reduce dependence on centralized power supply. This momentum is directly influencing demand across panel types, with monocrystalline and polycrystalline silicon panels seeing strong uptake due to efficiency and space optimization needs in rooftop settings.

The scale of this shift is evident in recent installation data. As of 2023, global rooftop solar installed capacity reached approximately 636 GW. Annual installations surged by 67 per cent in 2023, rising to nearly 175 GW from 105 GW in 2022. Corporate and commercial users continue to lead deployment, with around 62 GW installed in these sectors in 2022, compared to 43 GW in the residential segment. Annual rooftop solar installations are projected to reach 183 GW by 2024 and expand further to 268 GW by 2027.

On the residential side, rooftop penetration is expected to grow significantly, with global installations projected to reach 100 million systems by 2030 and 240 million by 2050. Regionally, China remains the largest market with about 225 GW of cumulative capacity in 2023, while countries such as the US, Germany, Brazil, Australia, and India are strengthening rooftop adoption through residential growth and targeted distributed solar programs.

Rooftop Solar Advances with High-Efficiency Modules and Large-Scale Deployments

• In December 2025, JinkoSolar commissioned a 9.728 MWp rooftop solar system at Bangkok’s Krung Thep Aphiwat Central Terminal, Thailand’s largest railway station serving over 600,000 passengers daily.

• In November 2025, Foulath Holding and Yellow Door Energy announced plans for a 123 MW solar project in Bahrain, comprising ten rooftop and four ground-mounted PV plants with nearly 190,000 panels spanning 707,000 sqm.

• In August 2025, JinkoSolar launched a 48-cell rooftop-optimized module in its Tiger Neo series featuring TOPCon 3.0 technology and dual-glass design. The 475W module delivers over 23.77% efficiency, maximizing power density for constrained rooftop spaces, with a 20-busbar layout that reduces resistive losses and micro-crack risk by 30%.

• In October 2025, JinkoSolar presented its next-generation Tiger Neo 3.0 48-cell modules at All Energy Australia 2025, designed for rooftop applications in the Australian market with higher efficiency, improved low-light performance, and reduced Levelized Cost of Energy.
