Subtasks

Subtask A: Collectors.

The objective of this subtask is to examine existing testing and certification procedures for low-temperature evacuated tube and flat-plate collectors, air heating collectors, medium- to high-temperature concentrating collectors, to identify weaknesses, inconsistencies in application, and significant gaps. The research will result in new or improved tests that can be communicated to ISO/TC 180 for consideration in updating old standards or developing new standards. Results will be promoted to certification bodies when they are relevant for consideration in how product certification is implemented. Methods include round robin tests to refine existing test procedures, in cooperation with researchers, industry and certification bodies involved in these technologies. The task will also establish ongoing information dissemination and communications to provide necessary information and feedback among participants, industry, and certification bodies to promote harmonized standards and coordination among certification bodies.

Subtask B: Systems

The objective of this subtask is to examine existing testing procedures for entire systems and identify weaknesses, inconsistencies in application, and significant gaps. Testing research will investigate component/material substitution issues, including implications for qualification and safety testing. System performance characterization, testing, simulation and modelling and extrapolation will be investigated to help clarify key issues including accelerated aging testing and performance prediction. The research will extend to analyzing how system testing and performance characterization results can be applied to analysis and public dissemination of public benefit indictors, including environmental, economic, energy and occupant comfort indicators for solar thermal systems. Where appropriate, research results that have implications for testing standards will be communicated to ISO/TC 180 and/or certification bodies to consider. Methods will include round robin tests to refine existing test procedures, in cooperation with researchers, industry and testing bodies involved in these technologies. The task will also establish ongoing information dissemination and communications to provide necessary information and feedback among participants, industry, and certification bodies to promote harmonized standards and procedures.
