Hi, I have been looking into purchasing a solar power battery charger for my caravan. I wanted to go away the Easter weekend but have left it too late to have an electric hook up so I have been looking for a solar power battery charger so at least I can use my leisure battery to power the lights etc. Or would be better to purchase a generator but again I am unsure which one would power my tv and hot water heater. Your comments are greatly appreciated. Thank you Lorraine
