Your solar panels are generating electricity right now. If you haven't filed your Meralco net metering application, that surplus power is flowing into the grid for free — a gift to Meralco, not a credit on your bill. Real pesos. Gone every month. The good news: enrollment follows a defined five-step process, and most homeowners in the Philippines cross the finish line in under three months.
- Net metering credits your singil sa kuryente for excess solar electricity exported to the Meralco grid.
- You need a grid-tied solar system (≤100 kWp), electrical permit, and a few key documents.
- The 5-step process takes roughly 45–90 days from submission to live meter.
- A 5kWp system in Metro Manila can earn roughly PHP 1,275/month in net metering credits.
- Meralco installs the bidirectional meter for free — no extra cost to you.
What Is Net Metering — and Bakit Sulit Ito?
Net metering is exactly what it sounds like: your meter runs both ways. When solar panels produce more than your home consumes — a bright Tuesday morning, say, when everyone's at school or work — that surplus flows into the Meralco grid. Meralco credits your bill at the ERC-approved avoided-cost buyback rate: currently PHP 5–10 per kWh, depending on the ERC's annual avoided-cost determination (2026 Meralco rates sit toward the higher end of that range — verify the current figure on the ERC's published rate table). Your singil sa kuryente shrinks. Sometimes dramatically.
The legal foundation is the Philippine Renewable Energy Act (RA 9513), which requires distribution utilities — Meralco, VECO, and others — to accept surplus solar power from qualified households. This article covers Meralco, which serves Metro Manila and surrounding provinces. Cebu and the Visayas? VECO runs an equivalent program with a nearly identical process.
Requirements: Ano ang Kailangan Mo?
Get these in order before you submit anything. Incomplete applications are the number-one cause of delays — Meralco sends you back to collect missing items and your clock resets.
| Requirement | Details |
|---|---|
| Grid-tied solar system | Must use an approved inverter; system capacity ≤100 kWp for residential |
| Bidirectional kWh meter | Meralco supplies and installs this — you don't need to source it |
| Proof of ownership or lease | Land title, tax declaration, or lease agreement with landlord consent |
| Electrical permit | Issued by your local government unit (LGU) — your installer handles this |
| Single-line diagram | Must be signed and sealed by a licensed Professional Electrical Engineer |
| Meralco account number | Found on your existing electricity bill — the solar system must be under this account |
A good solar installer handles the bulk of this. They've submitted these packets dozens of times. If yours isn't offering to manage the paperwork, ask directly — or find one who will.
Paano Mag-Apply: The 5-Step Process
Here's the actual sequence, start to finish. No surprises if you know what's coming.
Bring everything to your nearest Meralco Business Center, or email [email protected]. Run through the checklist above one final time before sending — a missing item resets your place in the queue.
Meralco engineers inspect your solar installation and review every document. Allow 15–30 business days. This is the stage where they confirm your system is safe to connect to the grid.
Meralco sends a formal agreement outlining the buyback rate, billing cycle, and terms. Read it carefully. Then sign.
Meralco schedules and completes the meter swap — free of charge. This meter tracks both what you draw from the grid and what you push back into it.
Your solar-plus-net-metering setup is officially active. From this point, every kWh you export earns a credit on your next bill.
Magkano ang Matatipid Mo? Real Numbers
Put numbers to it. Carlo is a Quezon City homeowner — a composite of real customers — running a 5kWp rooftop system. Metro Manila sun yields roughly 550 kWh monthly from that capacity. Carlo's household burns about 400 kWh. That leaves 150 kWh flowing back into the Meralco grid every month.
At the 2026 ERC avoided-cost rate of approximately PHP 8.50/kWh (rates update annually — check the ERC rate table for the current figure), that's PHP 1,275 in net metering credits per month — applied directly against his singil sa kuryente. His effective electricity cost drops from around PHP 4,400 to under PHP 3,200 monthly, using Meralco's residential rate as reference.
| Scenario | Monthly Bill (est.) | Net Metering Credit |
|---|---|---|
| Before solar (400 kWh/month) | ~PHP 4,400 | PHP 0 |
| After 5kWp solar + net metering | ~PHP 3,125 | PHP 1,275/month |
The numbers compound fast. Without net metering, the payback period on a 5kWp system runs 7–8 years on self-consumption savings alone. Add credits from exported power and that timeline drops to 5–6 years. The remaining panel lifetime — typically 25+ years — becomes free electricity. And income.
Mga Madalas na Tanong (FAQ)
How long does the Meralco net metering application take?
Expect 45–90 days from first submission to live meter. Delays trace back to one culprit almost every time: incomplete documents at Step 1. Have your solar installer assemble and submit the full package — that single move can shave two to three weeks off the timeline.
Libre ba ang bidirectional meter ng Meralco?
Yes. Meralco supplies and installs the bidirectional meter at zero cost — ERC mandates it. You don't source it, purchase it, or schedule the installation yourself.
Can I apply for net metering if I'm renting my home?
Yes — with caveats. You need written landlord consent confirming your right to install on the property; our solar installation checklist includes a landlord consent template you can use. The system must also be billed under your Meralco account, not your landlord's.

Get Your Free Solar Assessment →- Net metering in the Philippines is a legal right under RA 9513 — Meralco cannot refuse a qualified applicant.
- The bidirectional meter is free; Meralco installs it at no cost to you.
- Expect 45–90 days from submission to live export — faster if documents are complete on Day 1.
- Excess kWh credits roll forward monthly and are settled in cash once a year.
- A properly sized 5–8 kW system can wipe out 50–100% of your Meralco bill within the first full billing cycle after approval.
If your solar system is already installed and you haven't filed yet, every month you wait is a month of export credits you can never recover.
