Solar E-Bike Charging

Can solar panels charge an electric bike?

Charging an e-bike with solar: E-BIKE BATTERY: 300-750Wh (0.3-0.75kWh). CHARGE TIME: 3-6 hours from flat to full. COST ON GRID: 1-3p per charge (7-18p/kWh). COST ON SOLAR: FREE. Your 4kW solar system generates 10-20kWh per sunny day — enough for 13-66 e-bike charges. Even on the cloudiest winter day: 1-2kWh = enough for 1-6 charges. E-bike charging is so energy-efficient that it's irrelevant to your solar economics. But it's a nice thought: your commute is powered entirely by sunshine. Annual e-bike electricity cost: £5-£15 on grid. With solar: £0. For comparison: a petrol car costs £1,500-£2,500/yr. An EV: £200-£500/yr. An e-bike on solar: £0.
