Rooftop Solar PV Market: Global Industry Analysis and Forecast (2025-2032)

The Global Rooftop Solar PV Market size was valued at USD 147.5 Billion in 2024, and the total Rooftop Solar PV Market revenue is expected to grow by 6.93% from 2025 to 2032, reaching nearly USD 252.11 Billion.
Rooftop Solar PV Market Overview
Rooftop solar photovoltaic (PV) systems harness the sun’s energy as it is being received and produce their own energy. A rooftop solar PV system consists of solar panels placed on roofs or on land adjacent to a residential, commercial, or industrial building. The rooftop solar PV system also has the components of solar panels, an inverter, a mounting structure, and monitoring. Generally, rooftop solar PV systems produce only clean and renewable energy from solar, avoid grid energy dependency, and save the owner costs. The rooftop solar PV industry globally is maturing quickly. Maturity is fuelled by low solar PV costs, technology advancement in production, and political support from governments worldwide. There are even more opportunities to grow using advances in technology for efficient solar cells (like PERC and bifacial solar), new storage technology, and new regulations requiring renewable energy discussions in legislation (tax credits, feed-in tariffs, and net metering). The continual shift toward electrification and smart energy management will further integrate rooftop solar PV systems into other energy systems.

Because of an emphasis on corporate sustainability and decarbonization, there has been a significant increase in commercial and industrial deployments. Additionally, the technological pathways to decarbonization (enabled by digitalization and smart technology) now provide sophisticated monitoring platforms that allow us to control the performance and operation of systems while remaining predictive for maintenance. Also, advancements are occurring from manufacturers in building-integrated photovoltaics (BIPV). For example, these solar products include solar elements being integrated directly into manufactured building materials at the manufacturing point, which effectively eliminates the appearance of solar as a separate element, as the element becomes an integral part of the building envelope.

In terms of the market share for rooftop solar PV, Asia-Pacific is the leader, primarily due to high energy demand and government support; China, Japan, and Australia are typically the leaders in capacity additions in this area. North America and Europe are large markets offering steady growth in rooftop solar PV consumption as well, in large part due to climate goals and energy independence. While the residential segment represents the largest share of total number of installations, the commercial and industrial segment typically represents a greater share of the total capacity installed, largely due to the amount of overall available roofing space.
Rooftop Solar PV Market Dynamics
Rising Energy Costs and Climate Ambitions to Fuel Rooftop Solar PV Market Growth

The continuous rise in the price of electricity from traditional utilities globally - particularly for large energy-demanding markets - continues to drive the demand for rooftop solar PV. Additionally, the increasing global commitments to climate goals and decarbonization have created another demand across homes and businesses for distributed clean energy generation. Given the growing political concern, many governments have also begun to provide strong policy support, including tax credits, subsidies, and net-metering practices, in response to energy independence and renewable objectives. Our expectation is that in every segment (residential, commercial, and industrial), the overall demand for rooftop solar, in both an economic and environmental context, is increasing and will likely continue to grow.

Vertical Integration Restructuring Supply Chains to Rooftop Solar PV Market Growth

Like other sectors, the global solar industry is consolidating as bigger manufacturers vertically integrate the production of panels, cells, and wafers to control price and ensure supply. This fact is putting more competition pressure on the smaller component manufacturers, but also may mean that companies that specialize in a specific technology (like advanced mounting systems or unique storage) will have the opportunity to form strategic partnerships. Strategic acquisitions, along with long-term supply agreements, seem to be both more necessary now to stabilize their businesses, but also, given industry instability from the last couple of years, the only "real" way to scale a business.

Emerging Markets Offering Massive Growth Potential to boost the Rooftop Solar PV Market

Rapidly increasing energy demand in fast-growing economies in the Asia-Pacific, Latin America, and Africa creates unprecedented opportunities for rooftop solar growth. These emerging-market regions typically have high solar resource availability, as well as large populations with limited or unreliable access to an electricity grid, and solar energy makes not only sense but a compelling resource option. Also, with favourable government policies, decreasing technology costs, and novel financing vehicles such as solar leasing, will help satisfy this energy demand in these price-sensitive markets where low-cost and reliable electricity is a necessity.
Rooftop Solar PV Market Segment Analysis
Based on Application Systems, the Rooftop Solar PV Market is segmented into On-Grid, Off-Grid, and Hybrid. On-grid systems are by far the most prevalent application, and have seen strong and steady demand due to their price competitiveness, grid support through net metering, and ease of installation. On-grid systems are the predominant and most viable rooftop solar PV applications because of their economic benefits and fit with existing infrastructure in the urban environment. The on-grid segment is driven largely by net metering policies, which help consumers reduce energy costs by exporting their excess power to the grid, allowing for a faster return on investment. The lower entry price point, as on-grid systems do not include expensive battery storage, makes them the most reasonable and feasible option for the vast majority of consumers.


Rooftop Solar PV Market Regional Insights
The rooftop solar PV market has been expanding quickly, benefiting from improved panel efficiencies, rising electricity prices, and changing decarbonization policies in the Asia-Pacific, North America, Europe, South America, and Middle East & Africa (MEA) regions.
