💡 How the Calculator Works

🔋 Battery Sizing

We calculate battery capacity at 12 V with 50 % depth-of-discharge, giving you 2 days of autonomy without sun.

🔆 Panel Sizing

Based on 5 peak sun hours per day in Kenya. We add a 25 % safety margin for cloudy days and cable losses.

🔌 Inverter Sizing

The inverter is sized at 1.25× your total peak wattage to handle startup surges from motors and compressors.

💰 Cost Estimates

KES estimates are based on current Kenyan market prices for panels, batteries, inverters, wiring, and installation labour.
