That's a very awesome Christmas gift for your boy, and it looked like he hardly needed any directions to get it put together!

That is really funny how it stops working if the direct sunlight is blocked 😄

Great to see you buddy! Thanks for the wishes. Chirstmas went by very quietly this year. More family and friends were gone, it's like unreal, but let's hope for a better year in coming few days.

The point is, we need a capacitor(battery in this case) to store the electric. And there's no capacitor is light weight enough to carry itself against the charging time from given voltage generated by via our solar panel. Put it this way, we can have a solar powered car, with a solar charger and a lithium ion battery. The car can function normally during day time, at the same time it charges it's battery. After sun goes down, the car can only drive with the power directly from the battery, but it can only last 5 miles because of the dead weight of the solar panel and the battery itself. LOL
