$40K for 9kW solar sounds really expensive, I advice you to shop a bit or consider Solar lease. I have a 10 kW plant from SolarCity installed in late 2013. It is a prepaid 20 year lease, meaning I own the electricity and they own the panels, and the total cost (including installation, pv, inverters) to me is about 10K.
You seem to be getting a 1 cent more for the electricity, so your only motivation for this must be to have a back-up. But the 7kW powerwall is daily cycle, it may be a OK backup but not beyond a day or two.
- localhost 12y agoWhere I live (WA state USA), there are some crazy tax incentives here for solar. Rough math: 1. 30% rebate on federal income tax, so that's $12K back in the first year. 2. $0.54 / kWh WA state energy production credit which is capped at $5K / year. The estimated power production of a 9kW array over 1 year should get me pretty close to $5K back. The production credit expires in June 2020, which means that best case I get $25000 back from the state. Without factoring in energy cost savings, I nearly break even in 5 years. Energy cost savings are somewhere in the neighborhood of $1200 / year with solar. If the only rationale was energy savings, it's not a good investment. However, the tax incentives make it very attractive indeed. More details on WA state incentives here: http://www.solarpowerrocks.com/washington/ http://www.solarpowerrocks.com/washington/
- sremani 12y agoThat is some killer state energy production credits. Now your plan makes complete sense.
