Net-Metering in the Philippines: A Guide

Turn your roof into a power-generating asset and earn credits on your bill.

What is Net-Metering?

Net-Metering is a government-incentivized program, mandated by the Renewable Energy Act of 2008, that allows homes and businesses with their own renewable energy (RE) facilities, like solar PV systems, to export their excess electricity to the grid. In return, they receive credits on their electricity bill, effectively spinning their meter backwards.

The Core Concept

Think of the grid as a giant, shared battery. When your solar panels produce more power than your home is using, you "deposit" that excess energy into the grid. When you need more power than your panels are producing (like at night), you "withdraw" it. Net-metering is the system that keeps track of these deposits and withdrawals.

How Does It Work?

The process is straightforward and tracked by a special bi-directional meter provided by your Distribution Utility (like Meralco):

  1. Production: On a sunny day, your solar panels might generate 8 kW of power.
  2. Consumption: At that moment, your home might only be using 3 kW to run appliances.
  3. Export: The remaining 5 kW of excess power is automatically exported to the utility grid. The bi-directional meter records this export.
  4. Import: Later that evening, when your panels aren't producing, you draw power from the grid as usual. The meter records this import.
  5. Reconciliation: At the end of the month, the utility calculates your net consumption: (Total electricity imported) - (Total electricity exported). You are only billed for this net amount. If you exported more than you imported, you receive a credit that can be carried over to the next month.
Key Benefits

Reduced Bills: Drastically lower or even eliminate the consumption part of your monthly electricity bill.

Energy Security: Contribute to a more stable and resilient power grid for the whole community.

ROI: Accelerates the return on your solar investment by monetizing every kilowatt-hour you produce.

Eligibility & Requirements

System Size: Your solar PV system must not exceed 100 kW in capacity.

Utility Account: You must be a customer in good standing with your local Distribution Utility.

Certified Installer: The system must be designed and installed by a qualified and certified solar provider like Solarix.
