Data sources and cutoff

Solar ROI Calculator

Rates last reviewed: July 4, 2026

Sources used

Meralco June 2026 residential typical-consumption and generation-charge tables
Davao Light June 2026 Original Franchise Area residential and generation-charge tables
Visayan Electric official rate page reviewed July 2026; Cebu numeric table not available, so the prior sourced retail value remains
Net-metering export credit assumptions based on utility generation-charge treatment
Philippine peak-sun-hour references, residential installed-cost benchmarks, and IEA 2023 grid emissions factor fallback

Important limitations

VECO and Other Region export credits remain estimates until current generation-charge references are sourced.
The Cebu retail rate remains the prior sourced value after the June 2026 Visayan Electric page did not expose a numeric table for verification.
Installed-cost brackets, self-consumption, derating, degradation, and rate escalation are planning assumptions.

User-entered inputs

Results depend on the monthly bill, location, roof type, and customer type entered in the calculator.

Your mileage may vary

Actual results may vary. Roof direction, pitch, shading, usable area, roof condition, structural capacity, wind exposure, local weather, equipment choice, utility approval, and your real consumption pattern can materially change cost, output, savings, and payback. Use this as a planning estimate, not a final quote or engineering assessment.
