Solar and Chest Freezers

Can solar power a chest freezer?

A chest freezer on solar: ENERGY USE: 150-300 kWh/yr (0.4-0.8 kWh/day). This is one of the lowest-consumption large appliances. Your 4kW solar system generates 3,500-4,200 kWh/yr — the freezer uses just 4-8% of this. COST ON GRID: £37-£74/yr. ON SOLAR: absorbed into your general household consumption — essentially free. A freezer runs 24/7 but cycles on and off. During solar hours: cycles are covered by solar. During evening/night: covered by battery or grid. With a battery: the freezer's 24/7 consumption is largely covered by stored solar. KEY TIP: keep the freezer full (or use water bottles as filler) — a full freezer is more efficient than a half-empty one.
