TASK 46: Solar Resource Assessment and Forecasting

This Task will address ways to improve our understanding of solar resources.

IEA Solar Heating & Cooling Programme

The Solar Heating and Cooling Programme (SHC) was established in 1977, one of the first programmes of the International Energy Agency, to promote the use of all aspects of solar thermal energy. The Programme's work is unique in that it is accomplished through the international collaborative effort of experts from member countries and the European Union.

The benefits of this approach are:

  • accelerates the pace of technology development
  • promotes standardization
  • enhances national R&D programmes
  • permits national specialization
  • saves time and money

What's New
  • IEA SHC Task 58: “We will need new and innovate designs for heat and mass exchangers” - Thermochemical materials (TCMs) used in storage tanks show higher heat capacities than water and smaller losses over time. They are crucial to an increase in solar use among consumers and the storage of summer heat for the winter season. However, they are also more complex than their water-based counterparts, which require only heat exchangers. (Posted: 2017-07-18)
  • The Second Solar Academy Webinar on Solar Heating for Industrial Processes Held - The second Solar Academy Webinar on Solar Heating for Industrial Processes was held July 6, 2017 with presentation from Christoph Brunner, Pedro Horta and Bärbel Epp. (Posted: 2017-07-06)
  • IEA SHC Task 55: Solar District Heating Means Big Business - Solar district heating is attractive business. Not only does this become obvious when looking at the 347 MWth of newly installed SDH capacity in Denmark in 2016, but also when one hears about Big Solar, a 250 MWth collector field – with 1.8 million m2 of seasonal storage – planned to cover 20 % of the energy demand in the Austrian city of Graz by 2020.

  • IEA SHC Task 54: Investigating Cost Factors Along the Value Chain - Researchers have worked intensively for one-and-a-half years across national borders to find ways of reducing the costs of solar thermal systems and making them more attractive to end users. The members of Task 54 of the IEA Solar Heating and Cooling Programme, Price Reduction of Solar Thermal Systems, have discussed the effects of standardised product designs or changes in product offerings on cost structures.

  • IEA SHC: New Task to Push Emerging PVT Industry - Inventors and start-ups have been trying to combine photovoltaic and solar thermal collectors into one product for many years. Finally, a new industry seems to be emerging. (Posted: 2017-05-21)
