It's possible, but it's not profitable. First: the electric water heater is small and cannot be used by families. Second: the electric water heater consumes too much and is not profitable. Third: Wall mounted solar power is a flat panel heat collector which can generate enough hot water. The water tank only provides water storage effect from the heat collecting plate to the water tank. I suggest the original is better.
Yes, but there may be no hot water when there is no sun or in winter.
Solar water heaters use solar energy to heat water and are an energy-efficient and environmentally friendly product. However, it will be affected by natural weather conditions, particularly in winter, and often cannot be used, or electric supplementary heating will be required. Many water heatersThese require the use of auxiliary electricity. Users of solar electric space heaters should be very careful when using them.
Solar water heaters absorb heat from the sun using solar collector panels to heat the water. When it rains for a long time, electric supplementary heating is necessary. Electric space heater is similar to the heating method of electric water heaters. Using electricity to directly heat water temperature also carries certain risks. If solar energy is added to electricity, it will be the same as the heating method of an electric water heater, it is immersion heating, and there may be risks such as leaks and dry burning.
