Three Basic Systems-

1. Grid Tied- These systems work in conjunction with the utility grid. They can be sized according to a particular set budget or a customer’s desired percent of utility power offset. Grid Tied systems are capable of net metering, but they do turn off when the grid shuts down. This is required by law to protect the lineman from the power your system is producing while they repair the grid.(see solar glossary for definition of Net Metering,).    

   We offer all three systems above with custom design and installation services.

2. Grid Tied/ With Battery Back up- These systems work in conjunction with the utility grid and are capable of providing power when the grid goes down. GTBB systems include batteries and are usually designed to provide power for only mandatory loads in the event of an outage. They are also capable of Net Metering.
3. Off-Grid- These systems are usually installed in areas where there is currently no existing local grid or areas where the expense of getting a utility feed to the location is too great an expense to be cost effective. Off-Grid applications are typically designed for individuals who intend to use far less energy on a daily basis than the average American home. Off Grid takes a very large system or a very “small” lifestyle.
