Your solar panels are producing more electricity than you can use — and right now, that surplus is disappearing into thin air. Net metering fixes that. Export the excess to the grid, and Meralco credits it directly against your next singil sa ilaw. Done right, your monthly bill can drop to near zero.
- Net metering lets you sell excess solar power back to Meralco — legally, under RA 9513.
- Systems up to 100 kWp qualify; the application is free but takes 30–90 days.
- Meralco's buyback rate is roughly PHP 9–10/kWh in 2026 — enough to gut your monthly bill.
- The #1 mistake: hiring a non-DOE-accredited installer. It will get your application rejected.
Ano ang Net Metering? (And Why Your Meralco Bill Could Hit Zero)
Net metering is a billing arrangement where your distribution utility — Meralco, VECO, or any local electric cooperative — credits you for the surplus electricity your solar panels push back into the grid. Your meter runs forward when you consume power, backward when you export it. You pay only the difference.
The legal foundation is solid. Republic Act 9513 (the Renewable Energy Act of 2008) mandated it, and the Energy Regulatory Commission enforces rules requiring all distribution utilities to offer net metering to qualifying customers. As of 2026, any grid-tied or hybrid solar system up to 100 kWp is eligible — that covers virtually every residential and small commercial installation in the country. Credits accumulate month to month but reset annually, so system sizing matters. Sayang naman kung mag-e-expire yung credits mo.
Paano Mag-Apply: Step-by-Step Net Metering Application sa Meralco
The process is straightforward. Patience is the hard part. Here's exactly what happens, start to finish.
-
1Install a grid-tied or hybrid solar system through a DOE-accredited installer. Non-negotiable — Meralco will reject your application if your installer isn't on the Department of Energy's accredited list. Verify accreditation before signing any contract.
-
2Get your system inspected and certified. Your installer coordinates this. A signed electrical inspection certificate is required before anything else can move forward.
-
3Submit your net metering application to Meralco. Required documents: solar system specifications, single-line diagram, proof of installer DOE accreditation, barangay clearance, and the Meralco application form. The application is completely free. In the Visayas, submit to VECO — same documents, same process.
-
4Meralco installs a bidirectional meter. This replaces your standard meter so the utility can track both consumption and export. Processing takes 30 to 90 days — often longer when paperwork is incomplete.
-
5Start exporting — credits appear on your next billing cycle. Once the bidirectional meter is live, surplus solar generation automatically offsets your bill. Walang additional action needed on your end.
Magkano ang Savings? Real Numbers for Filipino Homeowners
Savings before process — understandable. So let's talk actual numbers.
A typical 5kW system in Metro Manila generates roughly 550–650 kWh per month depending on roof orientation and weather. If your household consumes 400 kWh, you're exporting around 200 kWh back to the grid. At Meralco's approximate buyback rate of PHP 9–10/kWh, that's PHP 1,800–2,000 per month in credits. Stack that against the power you're not drawing from the grid at the retail rate (~PHP 11–13/kWh), and the combined monthly savings are substantial. Not sure what size system fits your actual consumption? Use our solar system sizing calculator to get a number specific to your home.
Take Jomar, a homeowner in Quezon City (a composite of clients we work with regularly), who averaged a PHP 7,500 monthly Meralco bill before going solar. After installing a 6kW system and enrolling in net metering, his net bill dropped below PHP 800/month. The numbers aren't magic — they just work when the system is sized right.
| Scenario | Without Solar | With Net Metering |
|---|---|---|
| Monthly consumption | 600 kWh | 600 kWh |
| Solar generation (5kW system) | — | ~600 kWh |
| Grid export credits | — | ~PHP 500–1,500 |
| Estimated monthly bill | PHP 6,600–7,800 | PHP 500–1,500 |
A well-sized 5kW solar system in Metro Manila can realistically offset 80–100% of a PHP 5,000–7,000/month Meralco bill — but only when net metering is properly set up.
Common Issues & Tips (Para Hindi Ka Ma-Hassle)
Most delays trace back to three avoidable mistakes. Know them before you start.
Processing delays. The 30–90 day window is an estimate — not a promise. Meralco's queue can run long. Follow up every two weeks, keep photocopies of every document submitted, and make your installer a co-owner of the post-submission process. Ang hirap mag-follow up kapag wala kang reference number at resibo.
Rejection due to non-accredited installers. The single biggest reason applications get bounced. Ask your installer for their current DOE accreditation certificate before you sign anything. If they hesitate or can't produce it, walk away. Our guide to choosing a certified solar installer walks you through exactly what to verify before committing.
Credits expiring unused. Net metering credits reset annually — they don't roll over forever. An oversized system generates credits that will simply disappear. Size your system against your real 12-month consumption history, not your worst-month bill.
The DOE maintains a publicly searchable list of accredited solar installers at their official website. Always verify before signing — your net metering eligibility depends on it.
Net metering pays off — but only if your installer is DOE-accredited and your system is sized for your actual consumption. Nail both, and your Meralco bill becomes almost optional.
Net metering is one of the smartest financial moves a Filipino solar owner can make in 2026. It turns your roof into a revenue source and can zero out your Meralco bill. The application is free, the law is on your side, and the savings are real. Get a DOE-accredited installer, size the system properly, and follow up until that bidirectional meter is installed.
Mga Madalas na Tanong (FAQ)
Magkano ang buyback rate ng Meralco for net metering in 2026?
Meralco's avoided cost rate sits at approximately PHP 9–10 per kWh as of 2026, per ERC guidelines. That's lower than the retail rate you pay (~PHP 11–13/kWh), which is exactly why self-consumption is your profit center — consume most of your solar output on-site, export a modest surplus, and the math works strongly in your favor.
Can I apply for net metering if I'm not a Meralco customer?
Yes. Net metering is available under Philippine law to customers of all distribution utilities — VECO (Cebu and parts of Visayas), BENECO (Baguio and Benguet), and local electric cooperatives nationwide. Same process, same documents, just submit to your specific DU instead of Meralco.
How long does the Meralco net metering application take?
Typically 30 to 90 days from submission of complete documents, though delays are common. The fastest approvals belong to applications where every paper is correct on the first pass — no missing diagrams, no accreditation gaps, no incomplete forms.
Net metering is a legal right. The process is defined. The savings are real. Between you and a near-zero Meralco bill stands a DOE-accredited installer and about 90 days of patience.

- The avoided cost gap matters. At PHP 9–10/kWh export vs. PHP 11–13/kWh retail, self-consumption is your profit center.
- Documents make or break the timeline. A complete first submission can mean 30-day approval. Errors mean 90+ days.
- Your installer is your partner. DOE accreditation isn't optional — and a good installer handles the paperwork with you.
- Non-Meralco customers qualify too. VECO, BENECO, and all local electric cooperatives operate under the same law.
