Solar modules

Solar cells are merged into larger units – the modules – in module production. They are framed and weather-proofed. The solar energy modules are the final solar products and ready to generate power. Sunlight is converted to electrical energy in the modules. The direct current produced this way is converted to alternating current by the inverter so that it can be fed into the public grid or, if the unconverted electricity remains in the house, it can also be used directly.

The modules are manufactured in Freiberg, Germany and Hillsboro, USA. A globally unique production process ensures that solar module production is fully automated at Solar Factory GmbH. The regular electrical and optical measurements performed during production and thorough testing in all phases of production assure quality. After framing, the final product is tested and packaged for shipment.

Production

The cells are wired as solar modules in a fully automated process. The solar cells are first soldered to cell chains, known as strings, during the wiring process. These strings are then connected to a matrix made of, e.g. 60 cells.

In the next step, this matrix is integrated into a layer sequence made of solar glass and three films that are laminated in a vacuum oven at 160 degrees Celsius to become a single unit that is weather-proof and impermeable to water and air. After the connection sockets have been automatically placed, the modules are put in a stable aluminum frame.

Finally, output is measured in standard test conditions, the final inspection is carried out and the entire system packaged.
