View calculation assumptions
- Illustrative estimate — not a binding quote or performance guarantee. Based on residential property type with 70% consumption offset assumption.
- Solar system installation cost assumed at ₦500,000/kW (includes panels, inverter, installation, contingency).
- Generation estimate: 4.5 kWh/kW/day (conservative for Nigeria ~4°-14°N; actual varies by location, season, and panel efficiency).
- Tariff used for estimate: ₦40/kWh (blended 2026 Nigerian rates; actual varies by DISCO and consumption band).
- Payback assumes no tariff escalation, consistent generation, and no major maintenance/replacement costs during payback period.
- Actual savings depend on roof orientation, shading, system degradation (~0.5%/year), inverter efficiency, and grid connection stability.
