Hi Snowman,
If you MUST be in the shade, then use shade tolerant panels (yes, Dorothy, they do exist).
My system is series / parallel with nominal input voltage of 33 volts to a Blue SKY 3024di MPPT controller. I get 7 amps from 256 watts of Unisolar panels (four panels), in leafy shade. In the sun I get 17 amps (if the batteries are hungry--or I'm using the inverter).
My system has fixed panels and those measurements are at solar noon.
I wish I could say I planned for a system that worked in the shade, but the truth is, I got lucky.
Amorphous panels have the "edge" for low light and probably shade. The down side is that they are not small.
Math time again! :)
Exam question: Amorphous panel makes 6 amps in low light and covers area X. What would be the amps in the same light for Poly panels covering the same area X?
