Might as well just get solar PV then, that's around 150W per m2.

- hatsunearu 5y ago150W electricity, so you need to run a refrigerator cycle to pump that heat out of your house, which comes at a massive efficiency penalty.
- zplizzi 5y agoRefrigerators actually have greater than 100% efficiency, often like 300% or so. Because you're just moving the heat, not creating it. Sounds like magic but it's not.
- hatsunearu 5y agoah true. though that number is coefficient of performance, not efficiency
- thescriptkiddie 5y agoAnd an efficient heat pump can move four times as much energy as it consumes. But if some special paint/tile/insulation can reduce your needed cooling capacity by 30% you'll save a lot of money on equipment.
