Adding Solar PV to Your EV

Here’s a new concept in electric transportation that I don’t expect to catch on.  Imagine you park your car somewhere on a sunny day, you unlock a roof-mounted container, and pull out an array of solar PV that you then unfold and drape over your car.  You plug the array into your car’s charge port.  When you’re ready to leave, you reverse the process.

While the car is parked, you get a maximum of 1200 Watts, meaning that you’ll need about 30 hours of sunshine to charge your base-model Tesla Series 3 from 20% SoC to 80%.

Aside from the issues of cost, added weight, wind-resistance, theft, and vandalism, how long will it take the average driver to conclude that this is a royal pain in the ass?
