Hello experts. Who can help me? In my energy savings certificate, a coverage ratio of the solar system for water heating of 62.5% was calculated. Since this value seemed very high to me, I had a solar simulation created by the manufacturer. This simulation resulted, due to the orientation of the system (west), in only 44% coverage. The question now is whether the real figures have to be used in the energy savings certificate or if some idealized laboratory values are allowed to be included.
