The Philippines added 899 MW of new solar capacity in 2025, according to the latest Renewable Capacity Statistics 2026 report released by the International Renewable Energy Agency (IRENA). This pushed the country’s total installed solar capacity to 3,892 MW by the end of 2025, up from 2,993 MW a year earlier.
Ground-mounted solar projects remain the main driver of the market. Data from the Philippine Department of Energy (DOE) shows the country had 3,492 MW of utility-scale solar installed, while behind-the-meter capacity stood at 52 MW.
Industry analysts say two major growth factors are the falling cost of solar technology and the government’s Green Energy Auction (GEA) program. The fourth auction round concluded last year, awarding more than 10 GW of solar, storage, and wind projects, making it the largest procurement round so far. The DOE has also confirmed plans for GEA-7, covering ground-mounted, rooftop, and floating solar systems, as part of its goal to secure an additional 25 GW of renewable energy capacity by 2035.
The commercial and industrial segment has also gained momentum due to rising electricity prices and increasing renewable energy commitments. In the residential market, the 6.5 MW Ning Ning rooftop solar project was completed in November, becoming the country’s largest housing-related rooftop solar project.
Several landmark utility-scale projects also advanced in 2025. These include the 197 MW Citicore Solar Batangas 1 project paired with 320 MWh battery storage, promoted as the Philippines’ first solar baseload power plant. Meanwhile, ACEN’s SanMar Solar Project continues construction, with its first two phases totaling 384 MW already operational. The full project is expected to reach 585 MW by 2027.
Floating solar is also beginning to emerge. The country’s first megawatt-scale floating solar plant, a 4.99 MW system on the Malubong reservoir, was completed last year, with further projects expected in the future.
Looking ahead, analysts expect the Philippines to install even more solar capacity in 2026, supported by its gigawatt-scale auction pipeline and progress on the Terra Solar project, which combines 3.5 GW of solar generation with 4.5 GWh of battery storage. Once completed, it will rank among the world’s largest integrated solar-plus-storage facilities.
To further accelerate growth, experts recommend expanding the country’s net-metering cap beyond 100 kW, improving grid integration, and easing restrictions on power exports from distributed solar systems.
it is currently one of the largest exporters of photovoltaic products in China.
