New Solar Keymark Network Rules Allow On-Site Testing
The Solar Keymark Network has expanded its range of options by including in situ testing. At a meeting in March 2019, a revised version of the Solar Keymark (SK) Scheme Rules was approved to allow collector efficiency tests in a real-life environment.

Seasonal pit heat storage: Cost benchmark of 30 EUR/m3
Denmark has had a steep – but successful – learning curve with regard to the cost and efficiency of seasonal pit heat storage, which is used to store sunlight in summer for heating purposes in winter. Take Sunstore 3, for example, a 60,000 m3 pit heat storage system built at a cost of 38 EUR/m3 of storage capacity in the town of Dronninglund in 2014: It has now reached a storage efficiency of more than 90 %.

Combining the strengths of collector technologies
Task 55 of the IEA SHC Programme is currently studying the benefits of systems equipped with both flat plate and parabolic trough collectors to supply thermal energy to district heating networks. Preliminary results from a project in Taars, Denmark, have been encouraging, indicating how their combined strength can be an asset across a wide range of solar district heating applications.

On-site collector testing: new standard in development
Once a large solar field is set up at its designated location, what tests can be conducted to show that it performs as expected? Soon, the IEA Solar Heating & Cooling Programme may have an answer to this question, as it is working on internationalising Denmark’s testing procedure.
