My first reaction was how stupid this is. Dirt, debris and other things will get on the panels and cause lots of problems, but after a few minutes I realized it’s actually quite brilliant.

There are three major costs of solar, the panels, the location, and the wiring + inverters. If the tracks are used as the wires (extremely low resistance paths back to an inverter), the location is wasted space so basically free, and the inverter can be placed anywhere along the path to remove the power from the tracks, the cost of this comes down to mainly the cost of the panel, which is actually pretty cheep these days.

The real challenges will be in cleaning & maintenance, vandalism, and modifying the track to limit the conductive paths (assuming they’re used for this).

It’s shockingly high. I live in the SF bay area and I’m a bit pissed off at how bad we’re getting screwed.

We have a Volvo XC90. Much bigger (and probably heavier) than your Bolt. It gets ~26MPG on the gas only mode. It has an 18.8kWh battery and can go ~30 miles on a charge. So again, bigger, heavier, and less efficient. At $0.50 per kWh, it takes ~$9 for 30 miles, and ~$5.5 in gas to go 26 miles.

That’s all great, but the real thing that will stop it is economics. We have a PHEV and I calculated it out and we pay $8 per gallon equivalent compared to $5.50 for regular gas. That’s a pretty big difference. Right now we ignore the EV part of the vehicle. (Live in California and I pay $0.50/kwh.)

We’re planning on getting solar shortly and that may make it feasible, but until then, it’s not.
