Frequently Asked Questions
How accurate are the electricity tariff rates?
Tariff rates are sourced from published utility company schedules and government regulatory bodies. They are updated regularly. Some countries have complex tiered or DisCo-based pricing — we reflect the most common residential rates. For billing disputes, always use official utility statements.
How is solar ROI calculated?
Solar ROI uses your country's average peak sun hours, local grid tariff (what you'd otherwise pay), and estimated system installation cost in local currency. The payback period is the time until cumulative savings equal the installation cost. Panel output degrades ~0.5%/year — our 25-year projections account for this.
What does PAYGO solar mean?
Pay-As-You-Go (PAYGO) solar allows customers to access solar home systems by paying a small deposit and then small weekly payments via mobile money — without needing a bank loan. After the payment period (typically 18–36 months), the customer owns the system outright.
Can I trust the generator fuel consumption figures?
Fuel consumption estimates use standard engineering figures: diesel generators consume approximately 0.28 litres per kWh at 75% load. Actual consumption depends on generator brand, age, load factor, and fuel quality. Our figures are conservative (slightly higher) to avoid underestimating costs.
