Gearmotors are what rotate the mirrors to track the sun. The module’s computer drives the gearmotors to focus each mirror’s reflected sunlight on the absorber. They are galvanized to give long life and they are double sealed to keep out moisture and dust. Attached to the frame by two screws, they can be replaced in a few minutes.
The absorber collects solar energy. There are two types of absorbers: FourFold™ absorber and Microgrid absorber. Regardless of the absorber type, four mirrors reflect sunlight onto the absorber’s active region.
