  • Is there enough sunshine in all regions?

    Solar thermal systems produce hot water whether the system is installed in Sweden, Germany, India, Tunisia or South America. The annual yield depends on the application (domestic hot water, pool heating, space heating), the local climatic conditions and system dimensioning (high or low solar fraction). The annual collector yield per square metre of collector area lies around 250 kWh/m2 for unglazed pool heating systems, 400 kWh/m2 for solar combi systems for hot water production and space heating in northern regions, and up to 700 kWh/m2 for installations in southern European regions used only for hot water preparation.
