Installation Process

Before a contractor starts installing the system, they’ll need to secure the correct permits (such as a building and electrical permit) and approvals (Energy Trust incentive, utility interconnection agreement).

This process will vary in time, depending on where you live and type of installation. Generally it takes 3-7 weeks. Once your contractor has all the required permits and approvals it generally only takes 1-3 day for their team to install the system. Some installation are more complicated and may require more time.. Following permits and utility inspections, you’ll be set to enjoy the benefits of the sun.

Equipment Mounting for Typical Rooftop Solar System

Your contractor will find a shaded north side for the location on your home where they will mount the inverter. The goal will be to have a location that does not get direct sunlight so that the inverter does not overheat.  For security reasons, interior locations such as a basement of a garage may be chosen, but small, confined spaces such as a closet will not work due to the danger of overheating.  In addition to mounting the inverter, a DC disconnect switch and a utility meter will be located close by.The output of the inverter and PV system will be connected to a circuit breaker in your breaker box.


The electrical connect from the solar panels, typically mounted on your roof, will be enclosed in a metallic conduit from the roof down to your inverter. The output of the inverter and your Solar Electric System is connected to a circuit breaker in your breaker box. The Electricity generated by your PV system will be used by the other circuits in your home, and any excess power will be sent through your electric meter to the local neighborhood.
