Panel efficiency is calculated before rated power. 4kW * 5 hours that’s 20kWh. At ideal tilt with solar tracking you can get close to 30 kWh/day from a 4kW worth of panels in ideal conditions, but flat panels are significantly worse.
The quote was 20-75 miles per day of range. Let’s assume 25% extra drag at highway speeds. That puts breakeven at 80-300 miles of highway driving per day which most people don’t do.

- Retric 3y agoInteresting, I just assumed 9*220W panels but I can see why went cheaper.
