Energy Balance

(100 points)

The Energy Balance contest requires teams to use only the energy generated by the solar electric systems (also called photovoltaic or "PV" systems) on their houses during the competition to provide all of the electricity for the contests. Teams earn full points if the energy supplied to the batteries is at least as much as the energy removed from the batteries during the competition.

A visitor to the home of the 2005 Virginia Polytechnic Institute of Technology team is amazed to see the battery bank which stores the home's solar energy. The home's batteries charge the team's electric car, visible in the reflection.
