I have recently installed a Sol-Ark 15k inverter and temporarily installed 20 Sunpower X21-335w panels. 15 panels on my pergola and 5 propped up towards the afternoon sun. This is temporary as I don't know the rules for pergolas and was excited to see the 15k function and the old roof issue.
My roof is 24 years old and has a few areas that look like its loosing the granules at a higher rate. So the roof will need to be replaced before I put the new panels on the roof. Meanwhile, I was hoping to get some advice on the placement of the panels after the roof is installed.
The Sol-Ark 15k has three MPPT inputs. My house is pretty much East/West facing. I can use 3 strings of 6 per MPPT. So 18 panels per MPPT. I have only 40 panels right now, and also limited to the roof and pergola space. I could use the 3rd MPPT on the 3rd MPPT.
I also have 40 Tigo TS4-A-O units to tie in with the panels.
How would I string these panels on my roof? Attached are a couple of placement attempts. But with east/west facing, it is probably not a good idea to have the three south facing panels on the plans.
Any help would greatly be appreciated.
