Both the residential and the commercial segments have seen a boom in rooftop PV. With nearly two thirds of all new solar capacity installed on buildings in the EU in 2022, the deployment of solar rooftop installations will continue in the short term. The energy crisis has been contributing to driving the demand for rooftop PV installations, with homeowners striving to protect themselves against surging retail energy rates and looking for affordable electrical heat and transportation options.

This session will discuss:

  • Drivers & challenges for rooftop solar PV in Europe
  • Technical solutions for high levels of solar self-consumption
  • Business models for prosumers
