Results of IEA SHC Task 45 Subtask C “Systems - Configurations, Operating Strategies, Financing Issues”

The main objective of Task 45 was to assist in the development of a strong and sustainable market for large solar heating and cooling systems by focusing on cost effectiveness, high performance and reliability of installed and new solar thermal systems.Subtask C of Task 45 focused on system configurations, system performance, tools and guidelines for operating strategies, and models for ESCo services. The findings were prepared for 6 deliverables, C.1-C.6. To assure up-to-date results, first, more than 300 installed large solar thermal plants were evaluated in a database, operating in over 40 countries. The subtask C provides practitioners, researchers and officials findings on system configurations in a database, new tools, guidelines and templates to overcome a wide range of technical, financial and operational challenges when implementing large scale solar district heating and cooling (DHC) systems.
