Solar Electricity

Solar electric generation produces no pollution or emissions.  The energy required to manufacture a solar module is recovered in just 3-4 years of operation and the modules themselves will last 40 years or more.  Solar electricity reduces the effects of coal burning power plants such as mercury in our water and carbon dioxide in our air.   

Types of Solar Electric Systems:

Grid-tied PV Systems

Grid-tied systems are connected to utility power.  Instead of storing excess power in batteries, a grid-tied system sells it back to the utility.  These battery-free systems are lower maintenance and lower cost than an off-grid or multimode system.  Grid-tied systems need not provide all of the electrical needs of the building as the utility is always connected.

Multimode Systems: Grid-tied with Battery Storage

A multi-mode system combines a grid-tied system with the ability to store energy in a battery bank for use during a power outage or anytime you wish to disconnect from the utility grid.  In addition, you are also able to export excess power back to the electric utility.

Off-grid Systems

Off-grid systems are not connected to any utility power.  They store power in  batteries to be used whenever the sun is not present.  Off-grid systems require daily monitoring of your electrical usage.  They provide energy independence and are most cost-effective for remote locations with no existing utility service.
