The Eturnity PV Solution

The aim behind the Eturnity Solar Solution is to make the daily work of installers, fitters, energy suppliers and solar technicians easier. Until now, the workload for providers and customer consultants of PV systems has been from 12 to 20 hours. Thanks to the Eturnity Software, this workload is minimized and at the same time the work of the installers and energy suppliers is standardized and centralized.
