I recently acquired my first solar panel and I'm way excited to see the thing in action. It's a 90w Sunpower panel and I'm not sure what type of fittings are on the end of the pos/neg cords that extend out of the back. I'm new to the whole solar thing, but quickly trying to learn the ropes. I thought that the wires were fitted with mc4 connectors, but I was unable to affix them to other mc4 cables.
I got the panel from a craig's list trade and the owner didn't know much about the panel. Can someone please help me ID what type of connectors/cables I'm working with here?
Much, much thanks!
