“Would it be enough light to make a difference?”
Looks like the biggest residential skylight on those sites has a 18” diameter tube. Even using optimal assumptions…
0.164 m^2 x 1000 W/m^2 light intensity x 22% solar cell efficiency x 90% charging efficiency = 32 watts.
And that’s a with a lot of unrealistically optimal assumptions thrown in (midday, no clouds, sun directly overhead, 100% of the light transmitted, 100% of the light hitting cells, etc.).
And now that I think of it, I wonder how the Aptera’s solar array will react to spotty shade / inconsistent light intensity across the body of the vehicle. If it acts like a regular solar panel where partial shade on even a small part of a single panel can dramatically reduce output, a bit of light focused on one part of the Aptera while the rest is in shade might not generate hardly any power at all.
