Primarily I chose them for environmental reasons rather than financial. Solar panels are definitely now at a price point that they make easy financial sense (most systems pay for themselves inside 4 years). The Powerwall is probably nearer to a 10 year break even point at the moment but it also gives you some nice features such as power independence (i.e. it can power your home even if the grid is unavailable) so depending on what value you put on that feature they can make financial sense. The Tesla car however does not make financial sense at all 😆 That was a purely emotional purchase and I really should have avoided taking one out for a test drive. I had intended on only getting a Model 3 but Elon Musk knows how to sell: As you put in a pre-order for a Model 3 we would love to offer you a test drive of a Model S, which of the following days are you available? ... genius 😁
