Solar Permits and Requirements in the Philippines

A grid-tied home solar system needs three main approvals — an LGU electrical permit, a Certificate of Final Electrical Inspection (CFEI), and a Certificate of Compliance (CoC) — plus an anti-islanding certification on the inverter itself. None of these require a separate barangay permit, and a competent PCAB-licensed installer handles most of the filing.

LGU electrical permit

Filed with your city or municipality’s Office of the Building Official (OBO) before installation begins. It confirms the planned electrical work complies with the Philippine Electrical Code. LGUs are required to issue this permit within 3 working days of a complete application.

Certificate of Final Electrical Inspection (CFEI)

Issued by the LGU after installation, once an inspector confirms the completed system matches what was permitted. Current rules require LGUs to issue the CFEI within 7 working days of the final inspection. You’ll need this document for your net metering application — see how to apply for net metering for where it fits in the sequence.

Certificate of Compliance (CoC)

Signed by a PRC-licensed Professional Electrical Engineer (PEE) or Registered Master Electrician (RME), the CoC certifies the installation meets Philippine Electrical Code requirements — proper grounding, overcurrent protection, conductor sizing, and inverter safety features. Most installers have a PEE or RME on staff or on contract to sign this off; if yours doesn’t, that’s a red flag worth asking about.

Anti-islanding certification

Required for any grid-tied inverter under net metering, this confirms the inverter automatically disconnects from the grid during a power outage, protecting utility crews working on the lines. It’s typically bundled with the equipment’s own compliance documentation rather than a separate filing step.

Do I need a barangay permit?

No. Under current DOE rules, residential rooftop solar permitting runs through the LGU’s Office of the Building Official and your distribution utility — there’s no separate barangay approval layer to clear. See our DOE 2026 net metering rules guide for the fuller regulatory picture.

Who provides each document?

Why does the installer’s license matter here?

Because a PCAB-licensed, experienced installer is the one actually filling out and filing most of this paperwork correctly the first time. An installer who’s unfamiliar with your LGU’s process or your distribution utility’s document format is the single biggest cause of permit delays — see our guide to avoiding solar scams for warning signs that an installer isn’t set up to handle this properly.

What if a document is missing or wrong?

Your net metering application gets bounced back for correction, which resets the clock on your distribution utility’s review window. This is the most common reason applications take longer than the DOE’s mandated timelines suggest — not because the utility is slow, but because something in the document package didn’t match. Confirming your installer has a track record with your specific LGU and DU before signing a contract is the best insurance against this.

Does system size change which permits I need?

The core set — LGU electrical permit, CFEI, CoC, anti-islanding certification — applies to any grid-tied residential system regardless of size. Larger commercial and industrial installations face additional requirements outside the scope of standard residential net metering; if you’re sizing a system for a business, see our solar for small business guide.
