I am looking to install one or two panels on a rack system. For practical reasons I would like to place the panels "under" the crossbars of the rack (1in x 2 in aluminum extrusions). As such, there would be 3 extrusions going across the width (not length) of the panel and shading select cells permanently. I would only ever be able to accept about 40 watts in my system (I have a Jackery with obvious limitations — the watt input, as Will notes, maxes at 40), and could over-panel the Jackery by going with a 100 or 200 watt panel. So, the question—if I put up a 100 or 200 watt panel that is in some permanent shade, would the panel be able to generate my modest 40watts (assuming, of course, some good sun).
The question, really, is how shade affects these panels, when it is consistent and permanent.
