Solar PV Market Size & Share | Scope, and Trends for 2026-2035
Solar PV Market size is set to grow from USD 359.74 billion in 2025 to USD 976.36 billion by 2035, reflecting a CAGR greater than 10.5% through 2026-2035. Industry revenues in 2026 are estimated at USD 393.42 billion.
Growth Drivers & Challenge
One of the primary growth drivers of the Solar PV market is the strong global policy push toward decarbonization and clean energy transition. Governments across developed and developing economies are implementing supportive regulatory frameworks, renewable energy targets, tax credits, feed-in tariffs, and subsidy schemes to accelerate solar adoption. Solar PV has become a cornerstone technology for achieving net-zero emission goals due to its scalability, declining cost structure, and compatibility with both centralized and distributed power systems. Public investments in utility-scale solar parks, rooftop solar mandates for commercial buildings, and rural electrification programs are significantly expanding installed capacity. In addition, international climate commitments and pressure to reduce dependence on fossil fuel imports are encouraging countries to prioritize solar PV as a long-term energy security solution.
Another major growth driver is the continuous reduction in solar module and balance-of-system costs combined with technological advancements. Improvements in cell efficiency, such as the adoption of monocrystalline PERC, bifacial modules, and advanced inverters, have enhanced power output while lowering levelized cost of electricity. Economies of scale in manufacturing, particularly in Asia Pacific, have made solar PV increasingly cost-competitive with conventional power sources. The integration of digital monitoring, smart connectivity, and energy storage solutions has further improved system reliability and performance, making solar PV attractive for residential, commercial, and industrial users. As energy consumers seek predictable long-term electricity costs, solar PV is increasingly viewed as a financially viable and stable investment.
Despite strong growth prospects, the Solar PV market faces challenges related to grid integration and intermittency management. High penetration of solar energy can strain existing grid infrastructure due to its variable generation profile, creating issues related to voltage stability, frequency regulation, and power balancing. In regions with underdeveloped transmission networks or limited energy storage capacity, integrating large-scale solar installations can be complex and costly. Delays in grid upgrades, permitting challenges, and land acquisition issues for utility-scale projects further add to project execution risks. Addressing these challenges requires coordinated investments in smart grids, storage technologies, and regulatory reforms, which may slow deployment in certain markets.

Canada is also expanding its solar footprint, particularly in provinces focusing on clean energy diversification. The region benefits from advanced grid infrastructure, strong financing mechanisms, and increasing adoption of energy storage solutions, which collectively support long-term market growth.
Europe remains a key region for Solar PV deployment, driven by ambitious climate targets and energy transition strategies. Countries such as Germany, Spain, Italy, and France are expanding both rooftop and ground-mounted solar installations to reduce reliance on fossil fuels and imported energy. The European Union’s renewable energy directives and carbon reduction policies continue to stimulate investments in solar PV across residential, commercial, and utility segments. Additionally, rising electricity prices and energy security concerns have accelerated solar adoption among households and businesses. Technological innovation, combined with strong environmental awareness, positions Europe as a stable and growth-oriented market.
Asia Pacific dominates the global Solar PV market in terms of installed capacity and manufacturing capabilities. China plays a central role as both the largest producer and consumer of solar PV systems, supported by large-scale solar parks and export-oriented manufacturing. India, Japan, Australia, and Southeast Asian countries are rapidly expanding solar installations to meet growing electricity demand and reduce carbon emissions. Government-led auctions, declining module prices, and increasing private sector participation are driving strong momentum. The region’s vast solar potential, coupled with supportive policies and urbanization trends, makes Asia Pacific the fastest-growing market globally.

Segmentation Analysis
By connectivity, the Solar PV market is segmented into on-grid and off-grid systems, each serving distinct energy needs. On-grid solar PV systems dominate the market due to their integration with national electricity networks, allowing users to export surplus power and benefit from net metering policies. These systems are widely adopted in urban and industrial areas where grid access is reliable. Off-grid solar PV systems, while smaller in market share, play a crucial role in remote and rural regions lacking grid connectivity. They support energy access initiatives, telecommunications infrastructure, and agricultural applications, particularly in developing economies.
Based on mounting, the market is categorized into ground-mounted, rooftop, and floating solar PV systems. Ground-mounted installations account for a significant share due to large-scale utility projects that benefit from economies of scale and high energy output. Rooftop solar PV systems are gaining traction across residential and commercial buildings as consumers seek to reduce electricity bills and carbon footprints. Floating solar PV, though emerging, is attracting attention for its ability to utilize water bodies efficiently while reducing land constraints and improving module performance through cooling effects.
By end use, the Solar PV market is segmented into residential, commercial, industrial, and utility-scale applications. Utility-scale solar dominates overall capacity additions due to large power generation projects supplying electricity to national grids. The commercial and industrial segment is growing steadily as businesses invest in solar PV to manage energy costs and meet sustainability goals. Residential solar adoption continues to rise, driven by rooftop installations, declining system costs, and increasing consumer awareness of renewable energy benefits. Together, these end-use segments contribute to a diversified and resilient Solar PV market ecosystem.
