[QUOTE="mygoggie, post: 1150709, member: 18916"] I have been playing on FreeCAD (once again a CAD package to learn) to get the optimum layout of the PV panels on the roof. [USER=25509]@Sarel.wagner[/USER] I have decided that I will install 20 panels and be done with it. At the moment this is more or less the layout which I am aiming for. [IMG]https://i.postimg.cc/ZYjqNBhQ/Solar-array-layout-with-N.jpg[/IMG] The western panels will be wired as 4S2P and the eastern panels as 3S4P. I am a tad hesitant about the two north eastern green panel as they point more SE than East. I have however found that this section of the roof gets the most sunshine in the mornings. More in fact, than the grey panels on the NE facing section. I can always do some test between these two sections and see what is what and relocate if needed. The eastern panels are 3S as I have some shading issues in this area during morning and afternoon sun. Rather let three panels not deliver than four. Next step is to calculate the fittings and extruded fiberglass sections required to install the panels onto. The wind of the past weekend reminded me once again why you need to design to accommodate the wind forces! Still waiting on the panels to arrive which actually is a blessing in disguise as there are so many other items to get in place. If you have some valuable input regarding the layout I would appreciate reading such! [/QUOTE]
