MKBHD, aka Marques Brownlee, recently posted a 1 year anniversary video about his Tesla Solar Roof and Powerwall experience. A pretty decent video. There were a lot of numbers to convince you, the viewer, and himself, that it was worth the 9 year pay back period.
Back in 2018, we installed a 10.4 kW Tesla solar panel system (not solar roof) with three Powerwalls for roughly $55K before tax incentives. Over the years I’ve come to think of the “cost” of a home energy system quite differently. Maybe I can convince you too.
If you do decide to order a system for your home, and don’t have a referral link from a friend, feel free to use mine: http://ts.la/william5655.
Cash or Loan
When we purchased our system, we chose to use Tesla Financing. There were a few reasons.
#1: Lower upfront cost than cash. Just 10% down to get started. IIRC, we got a 10 year loan.
#2: Since solar offsets your utility bill, you will partially pay the monthly loan with the savings from your normal electricity bill…
