There's so much to learn! Based on Will's video Mono vs Poly - Real World Test - Worth the $$? it sounds like Polycrystalline is the way to go but I'm finding a lot more options for Monocrystalline. Is Polycrystalline being the better option due to cost and efficiency still the case with panels...
I'm following William's build guide for 24v system and the panels he links to on Amazon are out of stock https://amzn.to/2FM7GlM. I'm a newbie so can someone recommend different panels to consider? Thanks!
