The 2021 IEA SHC Solar Heat Worldwide Report, a publication which has been published annually since 2005 under the framework of the Solar Heating and Cooling Technology Collaboration Porgramme (SHC TCP) of the International Energy Agency (IEA), was recently released. The goal of the report is to give an overview of general trends, highlight special applications and outstanding projects, document the solar thermal capacity installed in important markets worldwide, and ascertain the contribution of solar thermal systems to the supply of energy and the CO2 emissions avoided as a result of operating these systems. The data used in the report is collected from 68 countries.
Co-author Monika Spörk-Dür described the report:
The IEA SHC Solar Heat Worldwide Report ed. 2021 is the most comprehensive solar thermal market report worldwide showing market trends for 2020 and giving detailed figures for 2019. Besides common markets like for single-family homes, multi-storey houses as well as swimming pools it also provides data for solar thermal applications in connection with district heating systems and industrial heat that are on a rise worldwide. With regard to technological developments it glances at PVT collectors that have increased 9% on average between 2018 and 2020. New in this year’s report there is a chapter about PV systems directly heating hot water, where more than 11,500 systems have been installed in South Africa.
