Solar Panel Layout?
Me again....have questions on the best layout and mounting for the panels I bought. Panels = 58.27" x 26.58" x 1.38" (26.4lbs) Roof dimensions are roughly 100" wide by 251" long. This was my ini...

Sorry, I have no answers/comments about your post. However, I am very interested in the comments of others. I do have a couple of questions that I believe are relevant to your layout.
1) What type of controller are you going to use: PWM? MPPT?
2) How are you connecting your panels to the controller? In other words, what is the solar voltage going to the controller?
3) I have read about the shadow effect has on output performance but I have never seen it stated specifically for a design. Here is the chance for someone to address this issue for this design. Is the total system output less effected by monocrystalline panels when they are partially shadowed? How about when they are connected in series? How about when they are connected in parallel? Is a PWM controller better or not for handling shadows?
4) Knowing that there will be shadow issues for this setup, what would be the most beneficial selection of components: mono or poly crystalline panels? Series or parallel or series & parallel solar panel connection to the controller? PWM or MPPT controller?
5) Is it better to have the front of the panels tilted down to put wind pressure on the top of the panels when driving or vice versa? Is it even a design consideration?
I am looking forward to everyone's comments on this thread.
