Power SystemHow do solar panels supply energy for spacecraft? |
Efficiency is how good the solar panel is at changing the Sun's light to electricity . You can think of it as the percentage of the light that hits the panel that ends up as electricity. So a panel with 50% efficiency would be able to change one-half of the light that hits the panel to electrical energy. Scientists define it as the ratio of how much power the panel generates to how much power the panels receive from the Sun.
How do solar panels convert the Sun's energy into electricity?
What role does the Sun play in space missions like DS1's?
