You only get real power out of your solar for a few hours a day, at best. This needs to be enough to supply power to your equipment during those hours while also (hopefully) giving your battery bank a full or near full charge. Your panels will pretty-much work 24/7 though. I've gotten half an amp from the moon on my 2x 100w panels. > Is the power rating of the panels a peak, before efficiency or lack-of-sun losses are taken into account? Yeah. They can actually put out a tiny-bit more, but don't expect them to. Plan for them outputting peak 70% of what they are rated for, actually.
