I have six 100 W panels wired in series on the roof of my van. I can only get 180 W maximum out of my entire setup (with a Canadian winter, I'm expecting at least 300 W), and I think the problem lies in them being in series. Someone told me that the panel with the least amps will bottleneck the entire system amperage output (which makes sense), so I'm looking for a way to increase my total wattage output by getting rid of this bottleneck. Two of my panels bend over the front of the vehicle, so they're great when my van is facing the sun, but they do poorly otherwise (thereby causing a really low amp bottleneck).
I'm thinking of wiring the back 4 panels in series (grid_1), then the front 2 panels in series (grid_2), then wire grid_1 and grid_2 together in parallel.
Does this series-parallel setup that I'm thinking about make sense for optimizing my total wattage output? I've also read that microinverters can work around this bottleneck issue as well, does anyone have any thoughts/experience with that?
