How the Philippines ' rooftop solar surge can flip the energy emergency script

Rooftop solar capacity in the Philippines has likely doubled between April 2025 and April 2026, reaching approximately 1,300 MW. This growth is driven by surging electricity prices, which have reduced payback periods for residential, commercial, and industrial users to between 2.3 and 3.1 years. The report highlights a massive influx of solar panel imports from China and the emergence of domestic manufacturing. To further scale rooftop solar to a target of 3,500 MW with 4,500 MWh of battery storage within 24 months, the author recommends expanding low-interest loan schemes, legalising 'plug-and-play' solar kits under 800 watts, and implementing a distributed grid-battery project.

• Rooftop solar capacity in the Philippines likely grew from 721 MW in early 2025 to approximately 1,300 MW by April 2026, as generation data suggests an additional 600 MW came online in that 12-month period.
• The Philippines has become a major destination for Chinese solar exports, ranking as China's second-largest solar panel export market in 2026 and overtaking Pakistan in volume.
• Rising electricity prices and falling technology costs have significantly shortened the payback period for rooftop solar across all sectors between May 2025 and May 2026: residential fell from 4.0 to 3.1 years, commercial from 3.0 to 2.3 years, and industrial from 3.9 to 3.1 years.
• The Philippines currently faces some of the highest electricity costs in the region, possessing the costliest residential electricity price in Southeast Asia, the second-highest commercial price, and the third-highest industrial price.
• Domestic solar manufacturing is beginning to scale in the Philippines Economic Zone Authority (PEZA) areas, with Gstar opening 1 GW plants in May 2025 at Subic Bay and April 2026 at the First Philippines Industrial Park.
• To achieve a target of 3,500 MW of rooftop solar and 4,500 MWh of battery storage in 24 months, the report proposes three policy interventions: expanding loan schemes for private sector workers, creating a micro-generation exemption for plug-and-play solar below 800 watts, and building distributed grid batteries.
