How Net Metering Reduces Your Electric Bill
Net metering is what makes grid-tied solar so worthwhile in the Philippines. It lets you send unused solar power back to the grid in exchange for credits — so nothing your panels make goes to waste.
How it works
Enabled by the Renewable Energy Act (RA 9513), net metering lets homes up to 100 kW export surplus solar to the distribution grid. Your meter records both what you import and what you export.
At the end of the billing period, your export credits are deducted from your bill. In effect, the grid acts like a giant shared battery for your daytime surplus.
Credits aren't full retail
Here's the important detail many people miss: you're credited for exports at the utility's generation (or 'blended') rate — lower than the full retail rate you pay to buy power back. So a kWh you export is worth less than a kWh you use yourself.
That's why self-consumption beats exporting. The smartest move is to run heavy appliances during the day so you use your solar directly at full value, and export only the true surplus.
Getting connected
To join net metering you apply to Meralco for a net-metering agreement and a bi-directional meter. A licensed installer handles the paperwork, inspection, and commissioning as part of your project.
Once approved, your credits appear automatically on your monthly bill — no manual tracking needed.
Net metering credits your surplus solar, but exports earn less than retail — so using power by day is worth more than selling it. We build every grid-tied quote around honest net-metering math.
