The Philippines has over 500 solar installation companies — ranging from large, experienced EPC contractors to informal groups of electricians with minimal solar training. Choosing the wrong installer is the most expensive solar mistake you can make. Ask these 8 questions before signing any contract.
| # | Question | What a Good Answer Looks Like |
|---|---|---|
| 1 | Are you accredited by the DOE? | Yes, with accreditation certificate number available |
| 2 | Does your team include a PRC-licensed Electrical Engineer? | Yes — they should show the PRC ID; all electrical work must be supervised by a licensed EE |
| 3 | How many systems have you installed in the past 12 months? | Minimum 10+ residential systems; ask for references and site addresses |
| 4 | Can you provide a detailed Bill of Materials? | Yes, with brand names, model numbers, and specifications — not just "5kW solar system" |
| 5 | Do you obtain the electrical permit from the LGU? | Yes — this is legally required; an installer who skips this is cutting dangerous corners |
| 6 | What is your workmanship warranty? | Minimum 1 year on labor; 2-5 years is industry best practice |
| 7 | Who do I call if there's a problem after installation? | Direct contact number, not just a general hotline; verify response time commitment |
| 8 | Can you assist with Meralco net metering application? | Yes — reputable installers handle or facilitate this; it's not optional for grid-tied systems |
The DOE maintains a public list of accredited renewable energy service contractors. Ask the installer for their accreditation number and verify at the DOE website or by calling DOE at (02) 8840-2278.
