Just wanted to share our project. My wife and I are doing a 14.85 kW, 2 PW partial home back up solar roof. This is after 3 weeks of work. They estimate another 2 weeks. House is located in Mechanicsburg, PA.
The roof is about 5000 sq ft. Almost the entire south facing roof is PV (8.2 kW). A little bit is on east (2.1 kW) and west (2.1 kW) facing. A small amount is north facing (1.2 kW). Estimated first year production is 15595 kWh. We don’t have PTO and we won’t be moving in for a few more months to give you any real world numbers yet though. I hope this helps.
Yes, thanks for the numbers! That's a nice production number. Do you think you could have had more active panels if you wanted or did they max out your roof? House looks great, I bet you are looking forward to getting through the construction phase!
The remaining east-west roof space had no attic access and we didn't want conduits and electrical boxes outside the house. The remaining roof is all north facing so it wasn't really worth it. I wish we did 2 more Powerwalls and had whole home back up but we decided against it for now due to how much more that was going to cost. We plan on doing it in a year if Tesla allows buying Powerwalls separately again. Thanks! Yes, we are very excited. It will be a big upgrade from the 150 year old house we currently live in.
