Research project

SolProof – Compactness and fault resistance of solar heating systems

The competition between photovoltaics and solar thermal systems for available roof area and investment capital of house owners is putting pressure on solar thermal heating systems to reduce cost and to simplify the product. This project aims to assist manufactures in this task. The goal is to reduce the complexity of solar thermal systems, and reduce likelihood of failures during planning and installations. Criteria for defining compactness and fault resistance will be defined and subsequent applied to different heating systems in the test bench. For this purpose, the well-established CCT method will be simplified and combined with the criteria for evaluation of compactness and fault resistance.


This project is financed by the Swiss Federal Office of Energy (SFOE).
