Solar energy will not fall when not in use. The solar is directly attached to the wall, using high-strength expansion bolts. As long as there is no typhoon, there will be no risk within 10 years. Therefore, solar energy will not decrease when not used. Solar is the abbreviation for “solar water heater”.
Is external wall mounted solar water heater good? Advantages of external wall mounted solar water heater
The tilt of the panel mainly affects the efficiency of power generation by the tilt angle. with the sun. Energy production efficiency is highest when facing the sun; Solar cells use solar energy to convert into electrical energy, so the amount of sunlight directly affects the electrical characteristics of the solar cell.
First: in order to obtain the maximum cumulative sunshinein a day, the general orientation should be south. For example, if a house faces south, it can get the maximum amount of sunlight in a day. .
Second: The tilt angle must maintain a perpendicular relationship with the incident sunlight. The theoretical reference value of inclination angle in different cities in China is the latitude angle.
If designed as a photovoltaic curtain wall, electricity generation will be reduced by more than 30%

The Pros and Cons of Wall-Mounted Solar
It works, but it's not great.
The biggest advantage of external solar water heaters is that they can meet the needs of solar water heaters in urban high-rise buildings, because the collector tubes are mounted externally on the wall, in case of tube rupture; during use, it is easy to cause blfalls.
So when using an external solar water heater, it is better to place the collector tube on an open balcony, which can not only meet the usage needs, but also prevent it from falling straight down and causing injury to people. when the tube bursts.
Nowadays, more and more homes install solar energy, which brings great convenience to life. What are the advantages and disadvantages of wall-mounted solar energy? PChouse will lead you to learn more.
1. Advantages
1. The wall mounted solar water heater can be a separate solar water heating system. The water tank is placed inside the balcony or on the exterior wall, and the collector is placed on the south side of the building. On the balcony facing the building, the wall-mounted solar water heater uses flat collector tubes to convert absorbed solar radiation into thermal energy, allowingi users of high-rise buildings to benefit from free hot water. of the sun.
2. The successful application of flat plate heat exchange technology in wall-mounted solar products not only improves the thermal efficiency of balcony wall-mounted products, but also successfully realizes the integration of safety and service life of products and buildings. requirements, making the installation of water heaters extending to all floors instead of being limited to the roof, and greatly eliminating the hidden dangers of traditional solar water heaters such as freezing, easy explosion of pipes, Easy leaks and easy scaling.
2. Disadvantages
1. The demands are too high. For wall-mounted solar water heaters, since the water tank is hung on the balcony, there are certain requirements on the size of the water tank, whether the balcony can hang a flat collector and si the wall can support the load. questions that need to be considered.
2. Installation is complicated. The owner should first ask the owner if he is willing to install this type of solar power. Exterior walls, once installed, can affect the overall beauty of the building. Additionally, wall-mounted solar is more complex than traditional solar systems and more expensive than traditional solar water heaters. ?
