The above example figures are calculated using MCS MIS 3001 Solar Domestic Hot Water Calculation v1.0 guidelines and are based on an MCS compliant system using a south facing array on a 40° pitched roof connected to a cylinder of typical size with the typical number of occupants in London, UK.

Please note that the performance of solar heating systems is impossible to predict with certainty due to the variability in the amount of solar radiation (sunlight) from location to location and from year to year together with variability in heat demand. This estimate is based upon the standard MCS procedure and is given as guidance only. It should not be considered as a guarantee of performance.
