Why choose solar in Kenya?

Abundant Solar Resource

Mombasa and much of Kenya enjoy high solar irradiance (typically 4.5–6 peak sun hours daily) — ideal for predictable solar generation year-round.

Lower Long‑Term Energy Costs

Solar systems reduce or eliminate monthly electricity bills and protect you from rising KPLC tariffs, delivering stable, lower energy costs over decades.

Faster Payback & Financing Options

Typical residential and commercial systems often pay back in 4–8 years. Affordable financing and lease options make switching to solar accessible for many customers.

Resilience & Environmental Benefits

Solar provides reliable power during outages, lowers carbon emissions, and supports sustainable development for homes and businesses along the coast.

Are the calculator results accurate for my site?

The calculators provide indicative estimates. For a precise design and quotation we perform a free on-site assessment to account for shading, orientation and equipment choices.

How should I use the load calculator?

Enter realistic appliance counts and daily usage hours. The calculator totals daily and monthly energy which we use to size solar and battery systems.

Can I request a detailed quote after using the calculator?

Yes — use the contact form or call us and we will schedule a free site visit and provide a detailed proposal with accurate costing.

Do results account for battery/inverter losses?

Calculators use simplified efficiency assumptions. Final system sizing includes inverter and battery round-trip efficiencies which we confirm during design.

Can I save or export my results?
