Solar panels

Post by Ca11um43 » Sun Jul 20, 2025 9:36 pm

Next year I plan on going off-grid around Italy for 2 weeks, as well as some shorter off-grid trips around the UK. My first trip being next month. Luckily it is fairly local but apart from the few bits that the previous owner left in the van, it's not set up or ready to be used off-grid at all. I've already got a Renogy 100a lithium deep cycle battery, and a Renogy 30a DC to DC MPPT charger ready to be installed, so I'm now looking in to solar panels. I have an AFT roof and ideally don't want to block the window/sun roof, so I'm a bit limited on space. How much solar (wattage) would you recommend to have?

I will be running a 12v compressor fridge (JKF50) pretty much 24/7 as well as LED lights, charging phones, the water pump for the sink, 12v TV (occasionally), etc. So nothing major. The solar will only really be a back up in an unfortunate event where I have to stay parked up for a while, and to keep the leisure battery topped up once I'm parked for the evening.

Yes I did :D Just getting as many links/ideas as possible, then I'll measure my roof again when I'm next with my Bongo (I took some measurements before but it was a while ago). It failed it's MOT recently, so is off the road and I'm about to start the repairs to get it back for a retest...Need to plan ahead though, as I haven't got much time until my first off-grid trip in the UK!! So I will be starting to fit the electronics at the same time as the MOT repairs. Definitely keeping my busy lol
