I created a rooftop solar array for my Tesla Model Y.That I could easily drive with it. It gives me anywhere from 20 to 75 miles. Version one (1575 watts, 11 inches high) adds about 20 miles per day, version two (4000 watts, 5 inches high) can add 45 miles on average, and with DC-to-DC charging that could increase to about 63 miles for a five hour sun window.
This design focuses on minimizing weight and aerodynamic drag, using carbon-fiber telescopic tubes and rods. When expanded, the array covers the space of a US parking spot and is designed to reduce injury in case of accidental collisions.
I also explore the environmental benefits of my design and discuss its potential applications for larger vehicles like buses and delivery trucks. I conclude by sharing my plans for Beta Two, which will have a lower height profile and the capability to support larger solar panels, potentially adding 50-75 miles per day.
The Version one is light enough to be carried on the roof rack of your EV, it weighs less than 165 lbs (75 kg). When expanded, it fits in a standard parking spot — and generates 100% clean and net-positive power from the sun.Using nine 175 watt solar panels.
Beta One can add 6kWh to your EV per day, that’s about 20 miles (32 kilometers) with only five hours of sun. Plus, you can drive it anywhere — it can withstand bumps, water, snow, nature.
