What Permits Are Actually Required
A fully permitted solar installation in the Philippines involves four separate approvals from three different agencies. Most reputable solar installers process all of these on your behalf as part of the installation package — you should not need to go to government offices yourself.
🏛️ LGU Electrical Permit
Issued by your Local Government Unit's Engineering or Building Office. Required for any electrical work above minor repairs.
🏗️ Building Permit (Accessory Works)
Required because rooftop solar panels are attached to the roof structure, adding load and penetrating the weather barrier. Classified as "accessory works" in most LGUs.
⚡ PEC Compliance Certificate
Certification from a licensed Registered Electrical Engineer (REE) or Professional Electrical Engineer (PEE) that the installation complies with the Philippine Electrical Code. Required for both LGU permits and net metering applications.
🔌 Interconnection Agreement (Grid-Tied Systems)
For on-grid and hybrid solar systems connected to the utility grid, you must sign an Interconnection Agreement with your distribution utility (Meralco, VECO, CEPALCO, or electric cooperative). This is separate from — but often bundled with — the net metering application.
Typical Permit Timeline
LGU Permit Application Filed
Installer files for electrical and building permits simultaneously. Most LGUs process in 1–3 weeks. Some progressive LGUs fast-track solar permits.
Physical Installation
Once permits are approved, physical installation begins. Typically 1–3 days for residential systems. LGU inspector may do a site visit during or after.
PEC Certificate & As-Built Drawings
Installer's REE prepares the PEC compliance certificate and as-built single-line diagram documenting the completed system exactly as installed.
Utility Interconnection & Net Metering
Installer submits net metering application to your utility. Utility schedules inspection, installs bidirectional meter, and processes interconnection agreement.
What Happens If You Skip Permits
Some bargain installers skip permits to cut cost and speed up installation. This creates serious problems:
- Net metering is blocked: Distribution utilities require a valid LGU electrical permit and PEC certificate to process net metering applications. No permit = no net metering, ever.
- Property sale complications: Unpermitted improvements are revealed in due diligence. Buyers' banks may require remediate permits before releasing mortgage funds.
- Insurance invalidation: An unpermitted electrical installation may void your home insurance for fire-related claims.
- LGU penalties: If an LGU inspector discovers an unpermitted solar installation, you may face fines and be required to obtain retroactive permits — at higher cost and with possible rework requirements.
- Warranty complications: Some panel and inverter manufacturers require proof of proper installation (including permits) to honor warranty claims.
Red flag: If an installer offers to "skip the permits to save time and money," decline immediately. The permit fees — typically ₱5,000–₱20,000 total — are a tiny fraction of your system cost. The risks of skipping them are disproportionately large. SolarStream includes all permit processing in every installation.
The good news: A reputable installer handles every permit, document, and government coordination on your behalf. You sign some forms and provide your title — that's your entire involvement in permitting.
