Buildings.Fluid.SolarCollectors.Data.Concentrating.C_VerificationModel

Information

No model on the Solar Rating and Certification Corporation website tested to EN12975 standards provides all of the necessary information for modeling. Specific limitations are dp_nominal, G_nominal and dT_nominal. This data record was created to allow verification of EN12975 base classes despite the limitations in available data.
