Clever-Solar (Enerpro GmbH)

Clever-Solar was rated one of the best value-for-money balcony solar providers in Switzerland in an SRF Kassensturz test (conducted together with BFH Burgdorf). The XL set, with two 445 Wp TOPCon modules, delivers 650 to 750 kWh per year on average and, according to the manufacturer, pays for itself in under five years.

All products are approved for the Swiss market and come with a declaration of conformity needed to register the system with the grid operator. Orders go through the company's own online shop.
