IEA SHC Task 49/IV - Deliverable C3 - Performance assessment methodology and simulation case studiesMarch 2016 - PDF 0.65MB
Performance of a solar system or any other energy conversion system in general is often being considered in a too simplified way. Simple performance indicators or metrics like efficiency are often taken without any description of the operating and application conditions, of the system boundaries considered for its calculation.
The performance of a system however can be described in a broader sense as a concept including energetical, economical and environmental aspects of a system operation for a defined time period. The system boundaries considered should be clearly defined, and the operating conditions according to the application should be specified.
