EPC stands for Engineering, Procurement, and Construction — the standard contract type for solar installations. Whether you call it a contract, proposal, or job order, you are signing a legal document for a ₱150,000–500,000 investment. Here are the 6 clauses that protect you.
| Clause | What to Require | Red Flag |
|---|---|---|
| 1. Scope of Work | Detailed BOM with brand names, model numbers, quantities | Generic "5kW solar system" with no specifics |
| 2. Performance Guarantee | Minimum annual kWh output guaranteed (with recourse if not met) | No performance commitment, only equipment specs |
| 3. Payment Terms | Stage payments tied to milestones: deposit, delivery, installation, commissioning | 100% upfront payment required |
| 4. Completion Timeline | Specific completion date with penalty for delay | "As soon as possible" or no stated timeline |
| 5. Warranty Terms | Separate workmanship and equipment warranties; clear claim process | Verbal warranty only; no written warranty document |
| 6. Permit Responsibility | Installer responsible for obtaining electrical permit and net metering paperwork | Permits listed as "owner's responsibility" |
Never pay 100% upfront. An installer who requires full payment before starting work has no incentive to complete the job properly.
