Pilot projects show promising results for ultra-low-temperature district heating
District heating systems have long been a key component of urban energy infrastructure, but they also come with significant heat losses and energy inefficiencies. Three pilot projects across Europe have been testing a new approach: ultra-low-temperature district heating – with promising results. By reducing heat losses and incorporating renewable energy …
Zero-COVID policy in China hit solar thermal market
The pandemic is to blame for the fact that the Chinese solar thermal market shrank significantly in 2022, against expectations. The collector area produced in China last year was 12 % lower than in the previous year. The market volume was 16.5 GWth (23.73 million m2) according to the “2022 …

IEA SHC recommends conversion factor 0.7 kWth/m2 for statistics on concentrating collectors
The IEA Solar Heating and Cooling Programme (IEA SHC) recommends the factor of 0.7 kWth per square metre of aperture collector area for the conversion of area to power for statistics on concentrating collectors. This is an important step for international market statistics about new solar heat capacities. So far, …
Certification and labelling of new collector types
GSCN and the Solergy label are continuing to grow together. More than a year ago, the Global Solar Certification Network and the Solar Heating Initiative, which developed the Solergy label, agreed to cooperate. In the recent IEA SHC Academy webinar the two initiatives gave an update on the expansion of …
Conto Termico: Good incentive but with room for improvement
Conto Termico, the Italian national support scheme for renewable heating, has had an important impact on the solar thermal market. 83 % of the newly installed collector area between 2016 and 2021 received subsidies from the national scheme. This can be calculated by comparing the cumulative figures from a report …
Hotel sector is important sales channel for solar industry in Brazil
ABRASOL, the Brazilian solar thermal industry association, has just published its annual market report for the year 2022. Collector sales totalled 1.25 GW (1.78 million m2) – slightly lower than the record year 2021. The 2 % decrease was caused by the economic problems last year and the political uncertainty …
