IEA SHC Solar Academy: Price Reduction of Solar Thermal Systems

Having the image of being too expensive to buy, too complex to install, too costly to maintain, solar thermal often loses the race against other offerings in today’s heating sector. How this trend can be reversed is one of the key questions of the SHC’s Task 54 “Price reduction of solar thermal systems”. This webinar will give information on the solar thermal value chain and highlight parts with the highest cost reduction potential. Task 54 experts explain economic and technological mechanisms that could change the price structure of current solar thermal systems decisively through five practical examples.

We invite all stakeholders to join the webinar scheduled for Wednesday, March 14, from 15 to 16.30 CET

This will be the fifth of a series of webinars organized by the IEA SHC Programme’s Solar Academy and hosted by the International Solar Energy Society. A recording of the event and the presentations from the webinar will be made available on the IEA SHC website,, after the live stream. Join us for a discussion about the opportunities and challenges future role of solar heat in urban environments.
