Off-grid Solar Power Systems

An off-grid solar power system captures energy from sunlight and stores it in a battery bank for use in a structure which is beyond the reach of the main power grid.  Using solar panels to create an elecrical DC current, this current is then routed through a solar charge controller which ensures proper charging and prevents overcharging and helps to "float" the battery bank, meaning to keep the charge topped-off.  The current is then directed to the battery bank for storage and later use. 

In most off-grid solar installations, the current is drawn from the battery through a DC-to-AC solar inverter.  The AC current is then used to power household appliances and, together with a good energy usage plan, can power many of the needs of an off-grid home or other structure.

On-Grid Solar Power Systems

Grid-tied, also referred to as grid-connected and grid-interfacing, solar photovotaic systems are made up of several components that, when wired together, are capable of producing alternating current electricity using light from the sun.

These systems are designed to offset utility power usage and to compensate system owners for any excess wattage their systems produce through an arrangement known as "net metering".

This arrangement is, essentially, an electric power plant that is owned and operated by the home or business owner.
