How do solar panels supply energy for spacecraft?

How efficient are solar panels?

DS1's solar panels convert 22% of their available energy into electrical power. This may not sound very good, but it is much better than most solar panels. Most solar panels on people's houses, for example, are fairly inefficient. Less than 14% of the energy that reaches them will be converted to electricity. DS1's panels are so efficient, in fact, that unless the ion propulsion drive is running, DS1 is producing far more power than it needs.
