Solar vs KPLC: How Much Will You Really Save in Kenya?
KPLC tariffs in Kenya have risen sharply over the last five years. With domestic consumers now paying upwards of KES 30 per unit, switching to solar has gone from 'nice to have' to a serious financial decision.
What you currently pay KPLC
A typical Nairobi home consuming 600 kWh/month pays roughly KES 18,000–22,000 once fuel cost charge, ERC levy, VAT and inflation adjustment are added.
Small businesses on the C1 commercial tariff often pay KES 35,000–80,000 per month for similar usage patterns.
What solar costs you per unit
After installation, the effective cost of solar electricity in Kenya is around KES 6–9 per kWh over the system's 25-year lifetime — about a third of KPLC's tariff.
A grid-tied 5kW system in Nairobi will produce approximately 720 kWh per month — enough to cover most homes' daytime usage.
Real-world savings examples
5 kW residential hybrid: typical monthly bill drops from KES 18,000 → KES 1,500. Annual saving: KES 198,000.
10 kW commercial: bill drops from KES 60,000 → KES 12,000. Annual saving: KES 576,000.
50 kW industrial rooftop: bill drops from KES 480,000 → KES 105,000. Annual saving: KES 4.5 million.
