Philippines Solar Battery Calculator
Beat Meralco's high rates with solar + battery storage
Why go solar + battery in the Philippines?
The Philippines has some of the highest electricity rates in Southeast Asia. Meralco and other utilities charge around ₱12/kWh — roughly double the regional average. Combined with frequent typhoons that knock out power lines for days, the case for home solar + battery is compelling.
The country receives 4.5 kWh/m² of daily solar irradiance, with the dry season (Nov-Apr) offering near-perfect conditions for solar generation. Net metering has been available since the Renewable Energy Act of 2008, allowing homeowners to export excess power back to the grid for credits on their bill.
Key advantage: With Meralco rates rising 4-6% annually and typhoon intensity increasing due to climate change, solar + battery provides both financial protection and energy security. The payback period for a typical Manila home is just 4-6 years.

Why Filipinos are switching
- ✓ Meralco rates are among SE Asia's highest — solar cuts bills by 50-70%
- ✓ Net metering lets you earn credits for excess solar power
- ✓ Battery backup keeps the lights on during typhoon outages
- ✓ Rising electricity tariffs make payback faster every year
Things to consider
- ⚠ Typhoon season can affect solar generation — ensure panels are rated for 180+ km/h winds
- ⚠ Net metering applications can take 2-3 months — plan ahead
- ⚠ Condo installations may face HOA restrictions on rooftop panels
- ⚠ Battery lifespan is 8-12 years — factor replacement into your long-term costs
