What Is Solar Panel Installation in the Philippines?

Solar panel installation is the complete process of designing, permitting, mounting, wiring, and commissioning a solar photovoltaic (PV) system on a residential or commercial property. In the Philippines, a properly installed solar panel system connects to the Meralco distribution grid, generates electricity from sunlight during the day, and credits any surplus electricity back to the customer’s monthly bill through the ERC Net Metering Program under Republic Act 9513.

A solar panel system is measured in kilowatt-peak, or kWp. A 5 kWp system generates approximately 600 to 700 kilowatt-hours (kWh) of electricity per month under typical Metro Manila solar conditions, where the average solar irradiance is 5.1 kWh per square meter per day.

Why Choosing an Accredited Solar Installer Matters

DOE Accreditation

The Department of Energy accredits solar PV installers who meet Philippine government standards. Our team, equipment, and methods are formally recognized by the national energy authority.

ERC Net Metering Accreditation

The Energy Regulatory Commission accredits installers whose systems are eligible for the Net Metering Program. Your system qualifies for Meralco bill credits from day one of operation.

Meralco-Accredited Installer Status

Meralco-accredited installers are authorized to complete grid interconnection work within the Meralco franchise area, ensuring smooth net metering approval without delays.

PRC-Licensed Electrical Engineers

Philippine law requires a PRC-licensed Professional Electrical Engineer to sign off on all solar installation electrical plans. Every project is supervised by one.

The Complete Solar Panel Installation Process

Ten distinct stages from site visit to net metering activation. Physical installation takes one to three days. The full process typically takes two to four months.

Site Assessment and Shading Analysis

A SolarPro Install engineer evaluates roof area, structural condition, shading, and reviews your last 12 months of Meralco bills.

System Design and Sizing

Our engineers design a solar PV system sized to your load profile, specifying panel count, inverter capacity, and projected monthly energy generation.

Proposal and Quotation

A detailed proposal with system size in kWp, component specifications, estimated monthly savings, payback period, and total cost.

Contract Signing

We formalize the engagement covering scope of work, payment schedule, warranty terms, and timeline.

Permit Application

We prepare and file the Building Permit and Electrical Permit with your LGU. Processing typically takes two to four weeks.

Solar Panel Installation

Inspection and CFEI

The LGU inspects the installation and issues the Certification of Final Electrical Inspection (CFEI), required for the Meralco net metering application.

Net Metering Application Submission

We submit the Application Form, CFEI, Amended NMA, and COC Application Fee to Meralco.

Meralco Distribution Impact Study

Meralco conducts a DIS and inspects your facility before approving the grid connection.

Bi-Directional Meter and Commissioning

Meralco installs your bi-directional meter. DIMC fee shall not exceed ₱3,000 for residential per ERC Advisory September 22, 2025.
