Can solar power a dehumidifier?

A dehumidifier is ideal for solar power: it uses 0.2-0.5kW continuously — well within your solar system's capacity. Running 6 hours/day on solar: ZERO cost. On grid: £0.30-£0.75/day (£110-£275/year). Solar saves: £110-£275/yr on dehumidifier running costs alone. Best strategy: run the dehumidifier during peak solar hours (10am-4pm) using a timer. This dehumidifies while solar is generating, storing the benefit (dry air persists for hours after the unit switches off). Particularly useful in: drying laundry (indoor racks + dehumidifier on solar = free drying), preventing condensation, protecting against mould in older homes.
