Why Apply for Net-Metering

Supporting the push for Solar and Renewables

More Filipino homes and businesses are choosing solar to lower their electricity bills while helping protect the environment. With abundant sunlight almost year-round, the Philippines has exceptional potential to turn sunshine into clean energy and savings.

Net-Metering unlocks even more value. Use the energy your solar system produces, export the excess to the grid, and earn bill credits on your next Meralco bill.

Power your needs, export the rest

Your solar system powers your home or business first, so you draw less from the grid. Depending on your actual demand and sunlight availability, it can cover your daytime use entirely.

When your solar system produces more energy than you use, the excess flows to the grid through a bi-directional meter. The meter separately records the energy you draw from the grid and the energy you export.

Meralco then applies the value of your exported energy as credits on your next bill.

Your system’s total generation may be measured using an optional REC meter or estimated through the ERC’s Gross Generation Formula, as provided under the 2025 Amended Net-Metering Rules.

Compute your savings

Your Net-Metering bill comes down to one formula:

Net Amount Payable (PHP) = Amount for Imported Energy (PHP) − Amount for Exported Energy (PHP) − Any amount credited from the previous month (PHP)

In practice: take the Export Energy (kWh) on your Meralco bill, multiply it by that month’s blended generation rate, and that’s your credit. Unused credits carry over to your future bills. They can’t be converted to cash.

Important Your exported energy is computed using Meralco’s monthly generation charge, based on its blended generation cost, before other generation adjustments.

Important Some government-mandated subsidy charges, including the Lifeline and Senior Citizen subsidy rates, are based on your total electricity consumption. This includes both the energy you draw from the grid and the solar energy you use directly.

Four Ks: What to KNOW before investing

KNOW the right size

Size your system to the power you actually use during the day, so you don't pay for panels you won't need.

KNOW the right requirements

Prepare your documents early and coordinate with your LGU for the Electrical Permit and CFEI to avoid delays.

Safety and compliance
