My solar system is 8.4 kw and included 18 kw of battery, it was $15k after tax credits and pays for itself over 7 years at the electric rate I was paying when I put it in. That was three years ago and I’m now running two AC units, a pool pump, charging the wife’s car and prices have gone up. I’m sure my electric bill would be $5-600 a month instead of the $200 it was so no doubt it’s paid for itself already, although I haven’t rerun the numbers. So yes it Is essentially free and it also makes me immune to the unreliable nature of our grid and the price increases in electric or gasoline. With the Silverado I’ll be working pretty hard to only charge off solar, I’ve got excess available during the day and my schedule allows. I’m considering an expansion of the system mainly to add more battery, while maybe not financially worth it now it would give me the luxury of more flexibility when I use the power and of course allow for more toys like AC and a hot tub. I could just float it all with minimal payments for some excess grid power, as I already do in some of the winter months, however being completely off grid capable appeals to me. We are saving $1500 a year running my wife’s car off solar instead of the gas we used in her hybrid before. For my truck the savings will be much more dramatic, something like $4-5000 a year at the way things are now.
To help you understand it really is free and more so pays for the truck. I’m driving a Cadillac now that cost $50k new, I didn’t buy it new but someone did, adjusted for inflation that’s a lot higher then I’ll spend on my Silverado EV new not including the $40k saved in gas over ten years.
I’m no tree hugger, I don’t care about CO2 other then I don’t live in the city and my life is such that I’m already many times greener then all my city dwelling liberal friends who won’t shut up about global warming and won’t do anything about it. I’m happy the truck will have zero emissions of the kind I do care about for me and my family, and local community. It wouldn’t make financial sense not to do what I’m doing, and I don’t mind getting a few luxury’s out of my truck along the way as it will be my primary vehicle to haul my wife and children around. I’ve gotten accustomed to things like having the AC on in my wife’s car without the engine running while waiting in a parking lot, good for me or the dogs. I like ventilated seats, surround view cameras for parking or making sure the cat is out of the way when backing down the drive. I like seat memory my wife is tiny, I like remote start, lock and unlock from the app, all four doors having touch unlock. I like the heads up display and lane keeping cruise control so I can text or drink a beer while it drives itself down the highway. I’m excited to run all my tools off the truck and leave the Honda generator at home. Wireless carplay would be nice, I’ve got it on the Kenwood deck in the Escalade. I like the digital rear view mirror too.
Hopefully my Silverado EV can come well equipped with the things I want for $70k and I’ll only be paying $30k after ten years. So it will be cheaper then your barebones wt and I’ll probably be living in mine. Kids can make appointments to see me in my office the AC will be running.
