How does the solar or wind hook up to the utility?
The solar or wind makes electricity, reducing how much is needed from the grid. The inverter is the point in a renewable energy system where the solar module or wind turbine output interfaces with the existing electrical system. The inverter allows for seemless translation between two differenet electrical sources. Many utilities will have an application process for the connection of the inverter to the the grid. This installation is best performed by a licensed electrician.
