I am trying to plan for my solar placement. Just a little background of how my pool and equipment pad are placed. The pool is on the south west side of the house. The equipment pad is on the east side of the house. I have three sections of roof I can put it on. Each roof is labeled as 1, 2 or 3 (see diagram below) with the following information:
Roof 1: East facing. Have approximately 23W x11H space to put solar panels. Please note that in the picture, there are trees that shade this roof. The tree has been removed so it gets full sun right now. If I use this roof, I can get five 4'x10' panel for a total of 200 Sq Ft.
Roof 2: West facing. Have approximately 18W x 16H space to put solar panels. I can put four 4'x12' panel for a total of 192 sq ft.
Roof 3: South facing. Have approvimately 16W x11h space to put solar panels. I can put four 4'x10' panel for a total of 160sq ft.
If I go with the south or west facing roof, I need to run the pipe from the equipment up the east wall, over the ridge and then to the solar panels. According to the diagram I found below, they suggest that I instll a 1/2" PVC pipe from the low point of the system and tie it back to the feed pipe.
Question: Is the 1/2" PVC pipe really needed? Wouldn't the main feedline automatically drain the solar panel by siphoning?
Where would you put the solar panel?
BTW - I live in northern California near Sacramento, so we get a decent amount of sun with little freezing,
