The typical components of your solar electric system:
Solar PV Panels — Generate DC electricity
Inverter — Converts the DC to standard AC electricity that is compatible with the electrical grid and capable of powering electrical devices.
Mounting Structure – Roof Mounted: Probably the most common type of mounting system, roof mounting, involves the panels being attached to an existing roof using a racking system.
Utility Meter — Tracks the solar electricity that your system produces and feeds to the utility grid, thereby keeping track of your credit from the utility.
