Combining Solar Power and Your Electric Vehicle — Too Practical to Pass Up (Reader Comment)

We recently got the following reader comment on a post of Andrew’s on electric vehicles, the smart grid, and residential solar power.

It’s a great one, so I thought I’d highlight it further with a quick repost here. Check it out: May I please emphasize this? “A small, 1.2-kilowatt solar system priced at around $4,000 will cover charging costs for an electric vehicle for up to 40 years.” For $4,000 you can buy your ‘gas’ for the next 40 years.

For the next forty years you will be producing the power for your EV for $8.33 a month. Those are fixed dollars, not dollars that will rise with inflation, the $8.33 per month is locked in. The $185 per month that ICEV owners will be paying for gas?
In forty years, based on past inflation, will cost you $1,027. Let’s use historical inflation rates to look forward to forty years from now… Price for gas now = $185. Price for electricity now = $8.33. Price for gas forty years from now $1,027. Price for electricity forty years from now $8.33.

Forty years from now $8.33 will have the buying power of $1.44 in today’s dollars. For less than the price of a latte, you charge your EV for a month. On an annual basis, $12,324 for gas, $100 for electricity. What’s not to love about that? (Yes, curmudgeons, there may be some inverter repair necessary along the way, and a tree might need to be trimmed back. Thank you in advance for grousing.)
