I want to get a solar power system going in my RV. I'm absolutly clueless and didn't know where to turn, so I thought someone with knowledge of electricity on this message board could help. I have a 28 ft RV, the manual says an outside power source is 115 Volts, the breaker box says 30 amps and at .11 cents/thing (?) we paid $50.00 over a months time when we camped at a campground. The RV packages are measured in watts and I don't know what to look for. Any advice??
