Seeing Alex's thread prompted me to look here for help.
I have bought an old caravan that has a seemingly just as old solar setup.
My problem is that it only puts out 2.5 to 2.8 amps on a sunny day, and I don't know what it should put out because it is screwed down to the roof,
and has no visible specs plate, and no info came with the van. Is there any
way I can find out how many watts the panel is. It is 900x 400 approx.
