The Philippines is blessed with abundant sunshine, making it one of the most promising countries in Southeast Asia for solar energy. With rising energy demands and a growing urgency to transition away from fossil fuels, the nation has invested heavily in large-scale solar farms. From Luzon to Mindanao, these projects are not only reducing carbon emissions but also proving that renewable energy can power communities at scale.
In this article, we’ll explore the top 10 solar farms in the Philippines, including their capacity, location, developers, and impact.
1. Meralco Terra (MTerra) Solar Farm – Luzon (Bulacan & Nueva Ecija)
- Capacity: 3,500 MW (planned)
- Storage: 4,500 MWh battery system
- Location: Bulacan and Nueva Ecija, Luzon
- Developer: Meralco PowerGen (Terra Solar Philippines Inc.)
- Commissioning: Phase I by 2026, full completion by 2027
- Land Area: ~3,500 hectares
The MTerra Solar Farm is set to become the largest solar and storage project in the world. By combining massive solar arrays with a 4,500 MWh battery energy storage system (BESS), it will ensure power availability even after sunset—paving the way for reliable and sustainable energy in Luzon.
2. Solar Philippines Concepcion Solar PV Park – Luzon (Tarlac)
- Capacity: 150 MW
- Location: Concepcion, Tarlac, Central Luzon
- Developer: Solar Philippines
- Commissioned: 2019
This project is one of Solar Philippines’ flagship developments, helping make Tarlac a renewable energy hub. Its large-scale output significantly reduces the region’s dependence on coal-fired power plants.
3. Cadiz Solar Power Plant – Visayas (Negros Occidental)
- Capacity: 132.5 MW
- Location: Cadiz City, Negros Occidental
- Developer: Helios Solar Energy Corporation (owned by Vena Energy)
- Commissioned: March 2016
- Land Area: 176 hectares (430 acres)
Cadiz Solar is one of Southeast Asia’s largest solar farms and a pioneer in the Visayas. With enough energy to power over 150,000 households, it has placed Negros Occidental firmly on the renewable energy map.
4. Alaminos Solar PV Park – Luzon (Batangas)
- Capacity: 120 MW
- Location: Alaminos, Batangas
- Developer/Owner: ACEN
- Commissioned: 2021
Operated by ACEN, the renewable arm of the Ayala Group, the Alaminos Solar Farm is a showcase of sustainable development in Batangas. It also integrates a reforestation initiative, pairing green energy production with ecosystem restoration.
5. Subic Bay Solar PV Park – Luzon (Zambales)
- Capacity: 100 MW
- Location: Subic Bay Freeport Zone, Zambales
- Developer: Emerging Power
- Commissioned: 2016
Located inside a former U.S. naval base, this solar park highlights the adaptive reuse of land for sustainable development. Its clean power supports Subic Bay’s industrial and commercial operations.
6. Ilocos Norte Solar PV Park – Luzon (Ilocos)
- Capacity: 83.3 MW
- Location: Ilocos Norte, Northern Luzon
- Developer: Vena Energy, MGEN Renewable Energy
- Commissioned: 2023
The Ilocos Norte Solar Farm taps into one of the windiest and sunniest regions of the country. By pairing solar potential with the province’s existing wind projects, it strengthens Northern Luzon’s position as a renewable powerhouse.
7. Ilagan Ground-Mounted Solar PV Project – Luzon (Isabela)
- Capacity: 440 MWp (~336 MWac)
- Location: Ilagan City, Isabela
- Developer: San Ignacio Energy Resources Development Corp. (Nextnorth Energy Group) with TotalEnergies
- Target Commissioning: 2025
- Land Area: ~392 hectares
Once completed, Ilagan Solar will become one of the largest single-site solar projects in the Philippines, providing significant power to the Luzon grid.
8. IslaSol II (SaCaSol III) – Visayas (Negros Occidental)
- Capacity: 48 MW
- Location: Manapla, Negros Occidental
- Developer: Bronzeoak Philippines for San Carlos Solar Energy Inc.
- Commissioned: 2016
- Land Area: 64 hectares
An expansion of the earlier San Carlos Solar projects, IslaSol II demonstrates the rapid scaling of solar power in Negros. Together with nearby facilities, it contributes to the province’s reputation as the renewable energy capital of the Philippines.
9. Malubog Floating Solar Farm – Visayas (Cebu)
- Capacity: 4.99 MW (scalable to 50 MW)
- Location: Malubog Reservoir, Toledo City, Cebu
- Developer: Carmen Copper Corp. with EPC contractor Black & Veatch
- Commissioned: August 2025
- Water Area: 3 hectares
The Malubog Floating Solar Farm is the Philippines’ first utility-scale floating solar project. It sets the stage for future developments on reservoirs and lakes, maximizing water resources for clean energy.
10. SanMar Solar Project – Luzon (Zambales)
- Capacity: 585 MW
- Location: Zambales
- Developer: ACEN
- Land Area: 500 hectares of lahar-covered land
Still under development, the SanMar Solar Project is a bold step toward repurposing lahar fields left by the Mount Pinatubo eruption. Once operational, it will transform wasteland into a hub of sustainable energy.
The Growing Importance of Solar Energy in the Philippines
From mega-solar parks in Luzon to floating solar farms in Cebu, the Philippines is positioning itself as a leader in renewable energy in Asia. These projects not only provide electricity to millions of households but also create jobs, attract investments, and reduce the nation’s dependence on imported fossil fuels.
With the government’s target of 35% renewable energy in the energy mix by 2030, solar farms will continue to play a critical role in shaping the country’s sustainable future.
