Hello,
I'm in the final stages of designing my DIY home grid-tie solar system and just wanted to run it by you guys to see if I'm missing anything. The basics are as follows: 35x 275W (CS6K-275M) for a total of 9.625kW. SolarEdge SE7600A-US inverter with 35 P300 SolarEdge optimizers. Twenty-nine (29) of the panels are facing South (170°) the remaining six (6) are facing West (260°). Two strings divided equally 18/17. String 1 will run at max 4,950-5,040W @350V --> 14.4A. String 2: max 4,675W-4,760W --> 13.6A. Existing electrical panel rated at 200A/240V. All wiring will be running in conduit inside the attic all the way to the attached garage (less than 60'). For the racking, I'm planning on using IronRidge XR100 rails on QuickMount Flashing E-mounts, although I'm open to other options. I'd prefer to be no more than 3" off the roofing surface. My main south roof is 33° pitch and the west side roof is 45°. The roof material is asphalt shingle. My next step is drafting up some diagrams/plans and applying for building and electrical permits. Already have applied for my local power company (Dominion Power) Solar Purchase program and have local HOA/town approvals. Hoping to start construction end of September with switch on date October 1st. Any other suggestions or advice?
