[QUOTE="Occasional_panner, post: 436278, member: 7956"] Don't get hung up about mppt or pwm, in the small systems like these they make so little difference it's simply not worth spending the extra money. Pwm will do perfectly well. If you have never used a multimeter before maybe a better idea to handball the job. I'd be happy to test it for you mate but I'm down in Melb. If you do want to do it, you'll need to open the junction box at he back of each panel and test the output of each one. Or a very rough way of doing it would be to cover half with something that completely blocked out the sun and test each half at a time. This will work as the panels will be connected in parallel. Sun will bounce off the ground too so don't just leave it folded in half and test that way, you need to completely block the sun from each side while you test the other side.
