Panels in parallel have to have same voltage. Panels in series have to have the same wattage. Batteries in parallel have to have same voltage and wattage. Batteries in series have to have same wattage. Panels and batteries get confused as how to combine them.
ya and its not even that easy. everything I have been read and explained to me on solar forums and what not, points to it doesn't matter it if series or parallel the smallest panel will set the tone, in volatage for parallel, or amps in series. I have a basic understanding of why, but I do want to dive into it deeper as the understanding I have now is not enough to expain why to someone if they ask.
I personaly have never seen this as I have always went with a single panel or identical panels and I only found this out when I asked about it on a large solar forum as I knew the sides where I can put panels were different widths. so basicly, if you have two different sized panels the way to go is two solar controlers, if you have three different size panels then 3 solar controlers, the batteries don't care what is sending them power, as long as its the right volatage.
