Joy, if you can make a list of the appliances which you intend to use, the rating or capicity of your fridge if it requires power to run it, is your lighting LED or not, what will your heating be in winter, whether you will be full time summer and winter or is this a holiday caravan, then some clever people here may be able to assist you with the minimum solar supply you will need. If you have the power ratings or consumption ratings for each appliance that would be helpful as well. Try and think of most things, a vacuum cleaner, a slow cooker and toaster for instance if that is your choice.

This will also assist with suggestions for the size inverter and the type or size batteries and most importantly how much solar you will need for trouble free days on the road in your new caravan.

For instance we run a 800watt electric toaster, and a small food processor and food mixer when required, Electric blankets for a short time before going to bed when it is midwinter and freezing outside, our Nespresso machine uses mega power but for a very short time and needs a minimum of an 1800 watt pure sine wave inverter to do this. My hairdryer is a 240v little travelling model it does spike up the power useage , again for a very short time. The slow cooker uses very little power but it does that for a lengthy period of time.

Hope these ideas will give you some ideas to get you started. ;)

Joy, many people with caravans find that very light, flexible solar panels mounted directly on the roof are the best option. These do cost more than the usual much heavier rigid panels, but they conform well to the caravan curves and are quite easy to mount with double-sided sticky tape.
Try very hard to site them where they will not be shadowed by vents, hatches, satellite dish etc.

Hi Joy,

Just in case you are not already aware there are panels available now that are 265w for a 1.65m long x 1m wide panel and 330w for a 2m long x 1m wide panel. Of course these are rigid panels (with glass over the cells and solid alloy frames) so they would need to be fixed / permanent mounted to your roof top and there are adjustable bracket kits available (for roof tops that are curved and not straight / flat) just letting you know in case you were stuck for options.

A typical Caravan / Motorhome or RV I would usually recommend at least 1 x 250w (or higher wattage panel) or 2 x 150w panels (assuming you want to have power during the winter months also) as typically solar panels produce between 1 quarter and 1 half the power output during winter months as they do during summer months, so it's just something to keep in mind and factor in.

If you needed any further info or had any other questions just ask as there's lots of great people on here to assist you.

Regards
Steve

And if a light user of power, don't forget the fold up portable type of solar panel. Can be easily connected to battery, can be moved around on ground to avoid any shadows and can be angled for optimum output. While we have a 120w panel on roof, the 90w portable panel puts out nearly as many amps due to no shadows etc.

I think there is a 120w fold up panel available. Storage of panel when travelling needs to be considered.

If this is an import caravan, I have been advised by several people that if gluing panels, you may have to import correct glue as some react with covering material.Worth checking as could be expensive.
