Solar Panel Golf Carts
Would a10w solar panel w/7a charge controller be enough to charge battery to run a 2.7cf Haier fridge?
Would 2-6volt golf cart batteries be better than 1-12 volt battery for this application?
There is no way a little 10W panel can provide enough power for a fridge, even a small dorm fridge like that. I found a site that said it (or a similar model) uses 750 watt hours a day. Without taking any losses into account, an average day has 5 sun hours (number of hours equal to a standard test condition, not hours of sunlight). So on a sunny day, a 10W panel can produce 50 watt hours (5 hours x 10W), that’s 700wh shy.
You would need at least a 200 watt panel.
As far as the batteries, you’d need about 100 amp hours. One 12V or two 6V in series doesn’t matter, as long as they are deep cycle batteries designed for this like golf cart (not car batteries), it will work.
