It's funny that you should mention solar panels, my neighbour has just had two 4' square solar panels installed on his house roof!

 

I've often thought about having a solar panel on the caravan but wouldn't know really how to begin putting one on and whats more, what will I gain?

 

I've gone off the topic here, perhaps you would like to move this post into Caravan Accessories??

The 4 foot ones on the house will be for hot water,

you could have a free standing one for the electrics, in the caravan. You can move it to face the sun :)

Are they any good. The ones I've seen for caravans are quite expensive, do they work.

Any information I can get will be most welcome, the website mentioned seems good but there is no replacement for personal recommendation.

I had a good look at these last year, wanted to avoid having to take my battery home from storage every couple of months for a recharge.

 

My dealer would not fit one to the roof for me, said it damaged the van and reduced its second hand value.

 

Looked at putting one under the roof window, but the manufacturers said they don't work well behind plastic glass.

 

Gave up and bought a good charger :-(

 

But, in the process I came upon various bits of information:

 

Someone makes roof mounting kits that you glue in place, no holes.

I remember someone doing some experiments and concluding that a panel pointed at the sky produces more power than one pointed at the sun.

There are several different technologies used to make them, some work better than others, some are aimed at specific conditions and markets.

Buy a good "series" regulator.

 

Don't be conned by ratings. One of the supplier's sites tells you how much power you will "really" get from a panel. They say the equivalent of 1 hour in winter and 3 to 5 hours in summer, that's all.

 

Here are a few links, there are many more, some have good advice on them.

Regarding the fixing of the panels to the roof, I would imagine that if you used a blob of silicone sealant at each corner to fix it, it isn't going to go anywhere once the sealant has set.

If you did that, I think you would lose your panel very quickly. A reasonable sized panel is quite heavy and the forces generated in a caravan bumping down the average road are amazingly high.

 

I always remember following a van being towed quite quickly down a badly surfaced country road, it was vary scary :-(
