I did a similar thing on my
bimini. I have a
single 100 oriented like your 135s, and two 40W modules in the aft corners. Each module has its own MPPT controller. I ran the wires down through the
bimini stainless tubing.
I used a Sunsaver MPPT on the 100, and two Genasun voltage boosting MPPT controllers on the 40s since they are only 8V modules.
Your research is correct:
To get the absolute most out of your array you should have a separate MPPT controller on each solar module. This is because of the partial shading you get on each of the modules. It looks like you have shading from the boom on the 135s, and from the split backstay(?) on the 55s.
MPPT controllers track the maximum
power point of an array or module, and if you have modules paralleled and each are getting shaded independently, the IV(current-voltage) curve and max
power point of the combined array gets very distorted and you end up getting less out of your array.
If you have to parallel all of your modules together then you are better off with a PWM type controller.
Don't series any of the modules, it will only make your IV curve even more distorted.
Put separate PV and controller out circuit breakers on each controller for
safety and so you can control and evaluate your output.
How did you hide the wires?
Have fun,
