What happens on cloudy days or in winter?
Solar collectors absorb ultraviolet radiation from the sun which heats the water even on cloudy days or in winter. The efficiency of the SWH system will, however, be lower than on a hot summer’s day. Solarise SQ58 SWH systems are designed to fit to, and augment your existing geysers, which act as an electrical backup for extended periods of “bad” weather or when there is need for extra hot water. Efficiency and reliability are seamlessly integrated in Solarise SWH systems.
