[QUOTE="binky, post: 544681, member: 490"] The panels are knackered, you've been sold a 🍋. If you just want an odd panel for a campervan, then you can live with what you have bought, but if you are trying to power your house, I would ditch these - flog them off. The voltages would possibly indicate one string is down, the cells are usually arranged as 3 sets, hence 3 bypass diodes. They could of course, just be old, panels degrade at upto 1% per year (usually less). [/QUOTE]
