Collector area for domestic hot water
To calculate the size of the solar system for DHW heating, the collector area should be calculated depending to the number of persons or to the volume of the possibly already existing solar storage tank. At least 1 m² collector area should be installed per each person for a normal demand (approx. 50 L/person). To reach a higher solar coverage, 1.5 m²/person is also possible. If the DHW tank already exists, 1 m² is usually installed for every 50 liters of DHW tank volume.
