Solar energy does not mean bigger is better. First of all, the larger the capacity, the higher the price. Secondly, it is wasteful to choose a capacity that is too large and cannot use so much hot water every day. Therefore, the choice of solar energy should be determined based on actual usage. The purpose of hot water, the number of people using it, etc. Generally, if used for bathing, washing face, etc., 30 ~ 40 L/person is enough (select according to personal bathing conditions). If there is a bathtub, etc., it is recommended to choose 50L. If you also want to use solar heating in winter, water for washing vegetables, dishes, clothes, etc. must be bigger!
620 liters.
Solar energy generally ranges from 80 to 620 liters. The solar water heater is a device that converts solar energyheat energy, causing the water to go from a low temperature to a high temperature. To meet the hot water consumption in people's daily lives. The conversion of solar energy into thermal energy mainly relies on vacuum collector tubes, which use the principle of hot water rising and cold water falling to create microcirculation in the water, making so hot water.
The larger the capacity of the water heater, the better you should choose the capacity according to your personal needs.
