Full Answer

Active solar energy involves equipment or an action to convert solar energy into a useful form. One example of active solar energy is the use of solar cells to convert energy from the sun into electrical energy that can be used in the home.

Passive solar energy does not require any specific action or equipment. An example of passive solar energy is strategically placing windows in a home to allow sunlight to enter and provide heat.
