IEA SHC Solar Academy: Solar heat and electricity: PVT solutions for buildings and industry

Over the past few years, PVT systems that combine solar thermal technology and solar PV have gained more attention. In 2018, IEA SHC started the Task 60 called “PVT systems” to better understand the applications of the technology. PVT solutions can be used in several ways which Task 60 is currently investigating with heating or cooling for residential, commercial, administrative or industrial buildings as the main application. This webinar will introduce the current status of PVT technologies, show examples of systems, analyze the markets and trends, talk about the key findings of Task 60 and open new horizons.

The webinar will welcome the following three presentations:

  • Jean-Christophe Hadorn: Why consider PVT systems?
  • Laetitia Brottier: Overview of the PVT industry and perspectives
  • Daniel Zenhäusern: PVT systems figure of merits and KPI

The webinar will be moderated by Bärbel Epp, founder and managing director of the German consultancy solrico for solar market research & international communication.

Q/A Session: The 90-minute webinar will include a 30 minutes Q/A session.

The webinar is organized by the Solar Academy of the IEA SHC Programme and hosted by ISES, the International Solar Energy Society .

Laetitia Brottier

After a double degree of engineering and entrepreneurship at the Ecole Centrale Paris engineering school and a PhD in energetics at the Paris Saclay Ecole Normale Supérieure University, Laetitia Brottier was at the origin of the DualSun hybrid concept and in 2010 co-founded the company to develop, industrialize and commercialize the technology. At the end of 2013, the DualSun was the first module in the world to pass the PVT IEC certifications. In 2020 DualSun launches its 4th certified version, ever more powerful and competitive. Today, as Head of Innovation and Research at DualSun, she is responsible for keeping DualSun as a technological leader on the PVT market.
