A Photovoltaic system is composed of the following main components:
|
- 1 - Modules
-
The modules are the main components of a Photovoltaic system. They act as energy collectors, and convert sunlight into electricity. Assembled together into an array, they determine the amount of electrical energy the system produces. Simple: the more module surface you install, the more electricity you can produce.
- 2 - Inverter
-
The inverter performs the necessary conversion of current, from the current generated by the modules (Direct Current or DC) to an Alternative Current or AC (identical to the current available from the grid). Inverters need to be accurately paired with the module arrays in order to achieve the best possible energy production.
- 3 - Electrical Panel
-
Power travels from the inverter to the breaker box or electrical service panel. The power from the electrical panel is then distributed throughout the home or business for use.
- 4 - Utility Meter
-
When the Photovoltaic system produces excess power (like during a work day at a residence), the electrical power will flow to the grid through the electric meter. This will cause the meter to run backwards, generating a utility credit that can be used to offset future usage. This is called net metering.
- 5 - Utility Grid
-
The utility grid is the infrastructure that links homes and businesses to electric power plants. The grid automatically provides electricity when household or business demand exceeds solar production.
