Small Solar Electric Balance-of-System Components

In addition to the solar cells and modules, a small solar electric (or photovoltaic) system consists of other parts called balance-of-system components.

The balance-of-system equipment required depends which of the following systems is being used:

A typical small solar electric system usually includes the following balance-of-system components:

  • Mounting racks and hardware for the panels
  • Wiring for electrical connections
  • Power conditioning equipment, such as an inverter
  • Batteries for electricity storage (optional).
  • Stand-by gasoline electric generator.
