As 2018 comes to an end so does our most recent Task on Solar Standards and Certification. SHC Task 57 built on the work of Task 43 on Solar Rating and Certification Procedures to develop, improve and promote ISO standards on test procedures and requirements for solar thermal products as well as to harmonize at the international level certification schemes. It is this harmonization work that sets this Task apart from our other work and the work begin carried out by other organizations. Task 57 participants leveraged the SHC platform of international collaboration to push a global certification initiative to improve the harmonization of certification schemes and avoid the need for re-testing and re-inspection of solar thermal products.
