What are the advantages and disadvantages of solar water heaters?

Nowadays, many families use this green and environmentally friendly solar water heater, which is mainly heated by solar energy to improve the water temperature, thereby providing hot water for each family in a timely manner. So what are the advantages of solar water heaters that everyone will have? Let's take a look together.
Advantages of solar water heaters:
1. The solar water heater system operates automatically and statically, without the need for special personnel to take care of it, without noise, pollution, electric leakage, fire, poisoning, and other dangers. It is safe and reliable, environmentally friendly, energy-saving, and beneficial to the country and the people.
2. The system has good thermal insulation performance and large heat storage energy. The thermal insulation water tank has a water storage function, which can meet the centralized use of hot water by a large number of personnel, and can also be used as an emergency water source when water is stopped.
3. With sewage purification function, the water source is clean and pollution-free.
4. Solar energy is a renewable energy source that is inexhaustible, environmentally friendly, and pollution-free. Only sunlight can cause abnormal operation. The energy-saving effect of solar water heaters is significant, which can save a lot of electricity costs. Once invested, the investment can be recovered within 2 to 3 years.
5. Solar energy only absorbs sunlight for heating, without the risk of gas poisoning and electric shock, and is safe and reliable to use. In addition, the design life of solar water heaters is 10 years.
6. High tech product, copper aluminum anodized composite plate core or all copper plate core, with high surface treatment process, good heat transfer performance, strong heat absorption ability, and large water yield.
Disadvantages of solar water heaters:
1. Solar water heaters rely heavily on sunlight, and in overcast days or winter, the heating effect can deteriorate immediately, making them usable throughout the year. If electric heating is used, the power consumption is very high.
2. It takes a whole day of sunlight to heat the water. When the weather is good, hot water can only be guaranteed at night. During the day and night, hot water is rarely available, and it cannot guarantee 24-hour hot water supply for users, resulting in poor comfort.
3. The lighting panel of the solar water heater must be installed on the roof, which is not only bulky and bulky, but also affects the aesthetics of the building (more obvious in high-end residential areas), and can easily damage the roof waterproof layer.
4. If the solar water heater is installed at a high place, it must be ensured that it is within the protection range of the lightning rod, or lightning protection facilities must be installed for the solar water heater to avoid lightning accidents.
5. The installation procedure for solar water heaters is complex, and if installed improperly, it will not only pose a safety hazard, but also affect the aesthetics. Moreover, solar water heaters are generally installed on the roof of buildings, making daily maintenance difficult.
6. The hot water pipeline is more than ten meters long, and it wastes a lot of water every time it is used; Photoelectric complementation cannot be properly realized
