Arguably the most important element of any solar design. Please let your electrical contractor know right away that you are planning to incorporate solar into your new build. If SunCommon is involved in the process early on, we can work with your contractor to choose equipment that is preferred for solar interconnections.
There are several electrical components to consider as it relates to solar: service size, main service panel location, utility requirements and existing utility infrastructure. A main breaker is required in the main service panel—no exceptions. Additionally, all projects require exterior utility equipment, such a production meter and system disconnect. For roof mounts, we strongly recommend including a 2″ conduit chase from the attic to the main service panel. To utilize this, our installers need access to your attic, and must have a clear working area by the main service panel.
