Description

Solar electric heating combined saving energy box Technical Field The application relates to the technical field of solar energy, in particular to a solar electric heating energy storage box. Background The traditional solar water heater mainly relies on the solar collector to collect heat to heat water, has a relatively single function, can only provide hot water, can not work normally at night or when illumination is insufficient, and an auxiliary electric heating device is needed to ensure the supply of hot water, so that not only is the energy consumption increased, but also the storage and the utilization of electric energy can not be realized. The electric water heater directly heats water through electric energy, and the electric water heater is not limited by illumination conditions, but has higher energy consumption, does not have a solar energy utilization function, and cannot fully utilize clean energy. Both traditional water heaters can not meet the requirements of users on hot water and electric energy at the same time, and have obvious defects in the aspects of diversity and flexibility of energy utilization. Under the great trend of accelerating the transformation of global energy structures to clean energy, solar energy is used as an energy source which is rich in reserves, clean, pollution-free and renewable, and the development and the utilization of the solar energy are widely focused. The photovoltaic and photo-thermal integrated technology is used as an important mode of solar energy utilization, and can provide domestic hot water and electric energy for users by simultaneously realizing photo-thermal conversion and photoelectric conversion, so that the comprehensive utilization efficiency of solar energy is effectively improved, huge application potential is shown in the fields of residential houses, commercial buildings and the like, but the existing photovoltaic and photo-thermal type water heater still has the problems of low energy utilization rate and lower use safety.
