Net Metering Philippines 2026: Step-by-Step Guide to Selling Excess Solar Power Back to Meralco

Ano ang Net Metering? (And Why It Matters for Your Kuryente Bill)

Yes — you can sell excess solar power back to the grid in the Philippines. That's exactly what net metering does, and for Filipino homeowners with solar panels, it's one of the fastest ways to shrink your singil sa ilaw every month.

Your panels generate electricity. Your home consumes what it needs. Whatever's left flows back to your distribution utility — Meralco if you're in Metro Manila, VECO in Cebu. Instead of donating that power for free, your DU credits your bill. The legal foundation is rock solid: Republic Act 9513 (the Renewable Energy Act) and ERC Resolution No. 09, Series of 2013, both mandate that distribution utilities must offer net metering to qualifying customers. This isn't a pilot program. It's law.

Paano Mag-Apply: The 5-Step Net Metering Process (2026)

1. 1
   Install a grid-tied solar system through a DOE-accredited installer.

   Off-grid setups don't qualify. You need a grid-tied or hybrid system, 100kW or below for residential. Your installer must provide official documentation of system specs — you'll need it for the next step. The accreditation check is non-negotiable with your DU.

2. 2
   Submit your application to your distribution utility.

   Metro Manila goes to Meralco. Cebu to VECO. Bring your latest electric bill, installer certificate, system technical specs, and barangay permit. Incomplete submissions are the single biggest reason applications stall. Submit everything at once and keep copies of all documents.

3. 3
   DU technical inspection of your solar system.

   A Meralco or VECO engineer visits to verify anti-islanding protection, wiring, and inverter specs. Scheduling typically takes one to two weeks after your application lands. Be present. A clean install passes the first time.

4. 4
   Sign the Net Metering Agreement.

   Once your system passes inspection, your DU issues the agreement. ERC Resolution No. 09, Series of 2013 gives them 30 working days from receipt of a complete application. Follow up at the three-week mark if you haven't heard back. Silence is not approval.

5. 5
   Bidirectional meter installation — credits start accumulating.

   Meralco swaps your old meter for a bidirectional unit that measures both consumption and export. From this point, every kWh you push back to the grid shows up as a credit on your next singil sa ilaw. You're officially earning.

Magkano ang Matatanggap Mo? Credits, Rates & Real Numbers

Net metering credits are calculated at the Retail Rate minus distribution, supply, and metering charges — landing at roughly PHP 5–7 per kWh credited to your account. You still pay PHP 11–14/kWh when you draw from the grid, so net metering won't zero out your bill. But it's a meaningful cut, every single month.

Take a 5kW system in Quezon City, a typical Metro Manila household exporting around 300 kWh of excess power per month. At PHP 5–7/kWh, that's PHP 1,500–2,100 shaved off the monthly bill. Against a PHP 280,000–350,000 installed system cost, the credits compound fast.

Unused credits carry forward for up to 12 months. After that, your DU converts the remaining balance to cash at the avoided cost rate — lower than the retail credit you earn monthly. Right-size your system so you're consuming most of what you generate. Always verify Meralco's current net metering rate on their official portal; it adjusts with generation cost reviews.

Net Metering Philippines: Common Questions Answered

How long does Meralco net metering application take in 2026?

ERC rules give Meralco 30 working days to process a complete application. Budget 30–90 days total — inspection scheduling and meter installation add time after approval, and submitting complete documents on the first attempt is the single biggest variable.

Puwede ba ang net metering kahit may battery storage?

Yes, hybrid setups qualify — only grid-exported solar generation earns credits, not energy discharged from batteries. Most Filipino homeowners use batteries for nighttime backup while net metering handles daytime surplus, and the two work well together.

What happens to unused net metering credits after 12 months?

Your DU converts the remaining balance to cash at the "avoided cost" rate — typically lower than the PHP 5–7/kWh retail credit you earn monthly. Right-sizing your system minimizes unused surplus and keeps the economics sharp.

Can renters or condo owners apply for net metering in the Philippines?

Generally no — net metering requires property ownership and your name on the Meralco account. Condo corporations can apply collectively, but individual unit owners cannot; if you rent, coordinate with your landlord directly.
