Solar Panel Installation in the Philippines
Solar panel installation in the Philippines varies widely depending on system size, location, and roof type:
- 1.6 kWp Grid-Tied: Starts at ₱108,000 (for ~₱12,000/month bill)
- 5.6 kWp Grid-Tie: Starts at ₱270,000
- System Size: Larger systems cost more but offer better ROI
- Panel Type: Monocrystalline vs. polycrystalline affects cost
2026 Cost Examples
| System Size | Monthly Consumption | Estimated Cost |
|---|---|---|
| Small (2kWp) | 224 kWh | ₱150,000 - ₱210,000 |

| Large (15kWp) | Large consumption | ₱900,000 - ₱1,260,000 |
Installation Process
- Consultation & Assessment — Assess energy needs and roof suitability
- System Design & Quotation — Detailed proposal with pricing
- Permitting — LGU permits (3-day electrical permit under 2026 rules)
- Installation — Panels, inverters, mounting (1-3 days)
- Inspection & Commissioning — Final checks (7-day CFEI under 2026 rules)
- Net Metering — Connect to grid and start saving
2026 Permit Requirements
Under Joint Memorandum Circular No. 001, s. 2026:
- Electrical Permits: 3 working days (previously weeks)
- CFEI (Yellow Card): 7 working days
- "Deemed Approved": If LGU misses deadline, application automatically proceeds
- Electronic Signatures: Now accepted
- No Notarization Required: For net metering agreements
System Types: On-Grid vs. Hybrid vs. Off-Grid
On-Grid (Grid-Tied)
