π‘ How to Size Solar Panels for EV Charging
Solar panel daily output = panel wattage Γ peak sun hours Γ· 1000 = kWh per panel per day. A 400 W panel in an area with 5 peak sun hours produces 2.0 kWh/day. Divide your daily EV energy need by this to get panels needed.
Peak sun hours vary by location: sunny regions get 5β7 hours, temperate regions 3β5, and northern regions 2β4. Enter your local peak sun hours for accurate results. System costs vary widely by region β enter your local cost per watt.
50 km/day at 6 km/kWh = 8.3 kWh/day needed. With 400 W panels and 5 sun hours: each panel produces 2.0 kWh/day. Panels needed: 5. System size: 2.0 kW.
