I want to fit solar power to our wee Autocruise Vista, on a budget. If I do it, it has to a viable set up. Is it worth thinking about a used system? Is there much available? Are kits any good or just cheap tat? I have read numerous posts, but am not particularly au fait with what is available and of any use on the cheaper side of things, or indeed what components are a must have, rather than a useful addition. Sorry if this subject has been flogged to death, but so far this forum has been a godsend. Cheers John.
