Solarman PHFrom bill to bi-directional meter
Net metering lets a grid-tie system export surplus solar power. The export becomes a credit on your bill. It is not a cash payment.
- 1
Bill
Your Meralco bill shows how much power you use. It sets the system size and is part of the application.
- 2
Survey
We check the roof, structure, shading and your electrical panel, then give a written quote.
- 3
Install
The grid-tie system is installed and tested. It powers your home during the day from switch-on.
- 4
LGU papers
Building and electrical permits and related documents are secured from your city or municipality.
- 5
Utility file
The net-metering application is filed with the utility (Meralco in Metro Manila), with the required documents and inspection.
- 6
Bi-directional meter
The utility installs a two-way meter that records both imported and exported power. Export credits start from here.
A bill credit, not cash
Once the bi-directional meter is in, power you export is converted into a peso credit and subtracted from your bill. You do not receive a payout. Exported power is credited at a lower rate than the retail rate you pay for imported power, so solar you use yourself is worth more than solar you export.
How long it takes
The LGU papers and the utility filing are separate from the installation and can take weeks to months, depending on your city, the documents and the utility’s queue. Your system still powers your home during the day while you wait; you just do not get export credit until the new meter is installed.
