Solar panels are on the roof. The inverter is humming. Now comes the part your installer probably glossed over: getting Meralco to actually count what you're feeding back to the grid. Meralco net metering requirements in the Philippines have a reputation for being bureaucratic. That reputation is earned — but the process is survivable if you walk in with the right documents. Here's exactly what you need in 2026.
- Residential owners with grid-tied solar systems qualify; submit via Meralco's e-Net Metering portal or walk in to any Meralco business center.
- Meralco charges zero application fee — budget PHP 3,000–PHP 15,000 total for the bidirectional meter and, where required, a Distribution Impact Study.
- Typical approval: 30–90 days for residential systems under 10kW, provided documents are complete on Day 1.
Ano ang Kailangan? The Complete Requirements Checklist
The single biggest reason applications stall is incomplete documents at submission. Meralco won't fast-track a partial file — they'll hand it back and restart the clock. Your DOE-accredited installer owns the technical side. The admin documents are yours to gather.
| Technical Documents | Legal / Admin Documents |
|---|---|
| ✅ Single-line diagram of solar system | ✅ Proof of ownership or lessor's written consent |
| ✅ Load schedule / electrical load computation | ✅ Government-issued ID (primary applicant) |
| ✅ Solar system specs (panel model, wattage, quantity) | ✅ Meralco account number (from your latest bill) |
| ✅ Inverter datasheet (model, brand, grid-tie compliance) | ✅ Barangay clearance (required in select service areas) |
| ✅ Net meter specifications (bidirectional) | ✅ Duly accomplished Meralco application form |
On VECO vs. Meralco: In the Visayas — Cebu, Mandaue, Lapu-Lapu — your distribution utility is VECO, not Meralco. Core requirements are similar, but VECO runs its own portal and its own timeline. Confirm directly with VECO if you're outside Meralco's Luzon franchise area.
Magkano? The Real Costs of Net Metering (Hindi PHP 0 Lahat)
Yung bayad sa Meralco mismo — wala. But free-to-apply doesn't mean free-to-connect. The real costs are in the meter and, for larger systems, the impact study. Here's the honest breakdown:
| Cost Item | Who Pays | Typical Amount (PHP) |
|---|---|---|
| Meralco application fee | — | PHP 0 |
| Bidirectional net meter (supply + install) | Homeowner | PHP 3,000 – PHP 8,000 |
| Distribution Impact Study (DIS) — larger systems | Homeowner (if applicable) | PHP 5,000 – PHP 15,000 |
| Accredited installer certification | Installer (not you) | PHP 0 to homeowner |
Most residential systems under 10kW either skip the DIS or get it expedited. The ERC caps what Meralco can charge under ERC Resolution No. 09, Series of 2013 — a regulatory ceiling that protects you from surprise fees. Ask your installer for a written cost estimate before you touch the portal. They should know exactly what applies to your system size and feeder area.
Paano? The Application Process Step by Step
"The biggest delay is almost always incomplete documents on submission day — double-check the checklist before you go."
-
1
Get a DOE-accredited installer to assess your system and produce all technical documents. Single-line diagram, load schedule, equipment datasheets — their job, not yours. If your installer can't produce these, find a new installer.
-
2
Submit the complete application package. Online via Meralco's e-Net Metering portal at meralco.com.ph — in 2026 this is the preferred route for most residential applicants. Walk-in submission remains available at any Meralco business center if you prefer face-to-face.
-
3
Meralco conducts the Distribution Impact Study (DIS). For systems 100kW and below, this is typically waived or fast-tracked. Larger systems or congested feeder areas trigger a full DIS. Your installer will know in advance.
-
4
Meralco inspects the installation and fits the bidirectional net meter. When Meralco sends the inspection notice, respond immediately. Slow replies add weeks to your timeline for absolutely no reason.
-
5
Sign the Connection Agreement. Done. Your next Meralco bill will reflect the new meter type, and credits start from your first full billing cycle.
Consider Rico, a homeowner in Parañaque — a composite of solar clients we see regularly — who submitted his file with a missing inverter datasheet. Meralco returned it within a week. By the time he resubmitted, he'd lost a month. His 30-day process stretched to 74 days. One missing document.
After Approval: What Happens to Your Singil sa Ilaw
Manage your expectations here. Exported solar energy is credited at the Blended Lifeline Rate (BLR) per kWh — not the retail rate you pay Meralco. The BLR is lower than the generation charge on your bill. Net metering isn't a 1-for-1 swap. It still cuts your bill meaningfully — just not as dramatically as some installers imply.
A 6kW grid-tied system on a well-oriented Metro Manila roof — minimal shading, decent sun hours — typically shaves PHP 3,000 to PHP 5,000 monthly from the kuryente bill. Use our solar system sizing guide to match your system to your actual daytime consumption pattern, not just your roof space. Households that self-consume most of their generation during the day consistently outperform those exporting heavily.
Under the Renewable Energy Act of 2008 (Republic Act 9513), distribution utilities including Meralco are legally required to accept net metering applications from qualified end-users. A complete, properly submitted application cannot be refused.
Most homeowners are pleasantly surprised once they're on net metering. Walk in knowing the credit rate is the BLR — not retail — and your first bill won't feel like a letdown.
Net metering with Meralco is worth it for most solar homeowners. Submit a complete package on Day 1, let your installer own every technical document before you open the portal, and you'll be earning bill credits within 90 days.
Mga Tanong (FAQ)
How long does Meralco net metering approval take in 2026?
For residential systems under 10kW: 30–90 days from a complete submission. The most common delay is missing or deficient documents at first filing. Commercial systems can run up to 6 months when a full Distribution Impact Study is required.
Is there an application fee for Meralco net metering?
No application fee from Meralco. Budget PHP 3,000–PHP 8,000 for the bidirectional net meter and PHP 5,000–PHP 15,000 for a Distribution Impact Study if your system size or feeder area demands one. Your solar installer can give you a precise estimate before you file.
Can I apply for net metering if I'm renting my home?
Yes — with your landlord's written consent. The solar system and net metering account must link to the property's existing Meralco account, so a signed lessor's consent letter is non-negotiable. No letter, no application.
The process isn't complicated. It rewards preparation. Get the paperwork right the first time, and your solar investment starts paying back faster than you'd expect.
