Solar in the Philippines
The Philippines has some of Southeast Asia's best solar resources, with 4.5-4.8 peak sun hours across major regions. With Meralco rates at ₱13.82/kWh (March 2026) and rising, solar payback periods of 6-9 years are common for well-sized residential systems. Philippine net metering (Republic Act 9513) allows grid-connected systems up to 100kW to export excess solar and earn bill credits from their distribution utility.
