Power a fridge with solarpower?

balroq · 12-31-08, 05:07 AM

Hi!

I read the blog entry about "DIY, Super-Efficient Fridge Uses .1 kWH a Day" on EcoRenovator and imediatly thought about my father whos in need of a fridge in his cottage out in the woods, it sounds like it would easily be doable, I mean .1 kwh per day would not even require a big solar panel?

Im not good at the "electricity" thing

could anyone tell me what I would need if it sounds like a good idea?

Hi Balroq, welcome on-board.

This post may reply to your question.

Just change 20W*24h by 100Wh.

Balroq, it can definitly be done. What kind of cabin is this? Is it just a weekend get away, or summer get away, or year round home? This will greatly effect the sizing of the system.

Sizing the solar array and battery capacity will be the tricky part as it is with any system. You'll definitly want to think of a way to have mains power backup just in case if you want this to be a 100% reliable system. However, if its just a weekend cabin, you could probably get away with a small and inexpensive system for pretty cheap.
