Megasol Energie AG (Aargau/Solothurn)

Megasol manufactures solar modules in Deitingen in the canton of Solothurn and is one of the few remaining module makers left in Switzerland. For customers in Solothurn and Aargau that means short distances and local customer service, something that's harder to get with imported systems.

Alongside standard roof-mounted systems, Megasol offers products for solar facades, in-roof solutions and custom colors. For commercial buyers with procurement policies that favor Swiss products, that's a concrete advantage.
