The PV Health Scan

A diagnostic health and performance check of PV plant operation

The PV Health Scan is a software-driven service for PV plant owners, operators and asset managers. It ensures the early detection of faults and performance degradation and gives you actionable recommendations on the root causes. This allows you to improve your performance return by more than 10%. We are able to do this by mining your PV monitoring data on our SynaptiQ platform.

Why?

An analysis of 197 PV plants revealed that 25% of all PV plants perform 8% (or more) below expectations. Where is your plant or the one you want to purchase? With 3E’s PV Health Scan, move your plant to the top tier and keep it there!
