=Solar Energy=

1.The challenge that NASA overcame by inventing solar energy is no electricity. They use the Sun's rays and transform it into solar energy/electricity. The goal of solar energy was to develop remotely piloted aircraft. Intended to fly unmanned for days at a time and requiring only advanced solar power sources that did not add weight.

2.Solar panels were invented to transform radiant light and heat from the Sun into energy. NASA invented this to overcome no electricity in space and some people also think they invented it because when you're in space you're closer to the Sun if you're on the right side, because if you launch the space shuttle with solar panels on it at midnight, it won't get any light from the Sun to power it up.

3.This spin-off I used on earth when people want to be environmentally friendly then they get solar panels and put it on your house on places where the Sun touches it most. Some people also do it because they don't want to pay for the electricity bill. It can also be put on buildings that use too much electricity and the people/person who own the building might be paying more than they can earn
