tnygroves Posted October 14, 2020 Share Posted October 14, 2020 What size solar panels would be used for off grid motorhoming? Any advice appreciated. :-D Link to comment Share on other sites More sharing options...
colin Posted October 14, 2020 Share Posted October 14, 2020 What length is a piece of string? *-) But seriously, time of year, what you want to run off it, and usage patterns such as staying in place or often moving. Without these there is no sensible answer. Link to comment Share on other sites More sharing options...
Den Posted October 14, 2020 Share Posted October 14, 2020 We always use a electric kettle and charge up the vacuum, phones ect with 2 x 100 AH batteries. All our Motorhomes have been fitted with 100w solar panels and had no problems. We only use sites maybe once or twice a year with hook up. This time of year can result in a lower recharge, but I’ve learnt to very briefly start the engine while the 1000w kettle is on. We have a quality 1500w inverter.

spirou Posted October 15, 2020 Share Posted October 15, 2020 As many as you can fit on the roof and it still won't be enough for several months of the year. Or...it depends Link to comment Share on other sites More sharing options...
Hughmer Posted October 27, 2020 Share Posted October 27, 2020 My 20 yr old panels are crumbling (literally) Trying to choose replacements.. The link that Matrix posted was very useful https://www.campingandcaravanningclub.co.uk/helpandadvice/technicalhelp/solar-power/ But so much choice. There aren't enough hours left in my life. Can anyone recommend a particular panel? Mine are each 450wide by 1000mm long, and I could probably put another on as well. I subscribe to the "as many as you can fit" argument. Chatting to a techie today, he asked why not fit one much bigger panel. But it would probably have to be rigid. But I think mine were semi flex. There's no air gap under mine. They're glued direct to roof. I understand the benefit of cooling the panel but I feel a bit cautious about lifting new ones on some of the grp mouldings that I've seen. They look vulnerable and I can't help wondering about wind noise. Any first hand recent experience most welcome Link to comment Share on other sites More sharing options...
