The lifespan of solar energy has a lot to do with the inner tank. Due to different processing methods, the shelf life may be as short as 3 years or as long as 30 years. Some brands will say that they can be used for 15 years when purchased, but they will be disposed of after 10 years of actual use, because the lifespan of the heating tube is only ten years. If it exceeds ten years, the safety factor will be. reduced and the risk of electric shock can easily occur.
Solar energy refers to the energy of thermal radiation from the sun, which is expressed primarily in what is often called sunlight. The sun shines everywhere on earth and there are no geographical restrictions. It is everywhere, whether on land or sea, on mountains or islands. It can be directly developed and used, easy to collect, and does not require mining or transportation.
Aadvantages of solar energy
1. The greatest feature of solar energy is its enormous energy. There is no energy source on earth comparable to solar energy. Solar energy is the radiant energy released by high-temperature nuclear fusion reactions inside the sun. The radiant solar energy that reaches the Earth's surface each year represents approximately 130 trillion tons of standard coal, which is equivalent to 10,000 times the total energy consumed worldwide each year.
2. Solar energy is a typical regenerative energy source. Moreover, it is precisely because of the renewable nature of solar energy that determines the renewable nature of almost all other renewable energy sources. In other words, the reproducibility of almost all other renewable energy sources comes from the reproducibility of solar energy.
3. Solar energy ist sustainable over time. For humans, it can be considered permanent and infinite. According to estimates of the rate of nuclear energy produced by the sun, hydrogen storage is enough to last tens of billions of years, and life on earth is also about billions of years. In this sense, we can say that. the energy of the sun is inexhaustible.
4. Solar energy is widespread. Almost the entire surface of the Earth is illuminated by sunlight.
5. Solar energy is a completely clean energy source and does not emit any polluting gases or harmful substances. Solar energy is the only energy source capable of maintaining atmospheric temperature balance without warming the climate.
6. Solar energy is the safest and most reliable source of energy. The development and utilization of solar energy can fully maintain the natural balance. The application of solar energy is notnot limited by mining, transportation and storage conditions.
How long can a solar water heater last?
The lifespan of qualified products is 15 years. The reason is that as long as the bracket is well made, it will not rust. or become deformed. If the water tank coating thickness is SUS304-2B or greater than 0.3, there will be no problem. The service life is mainly limited by the vacuum tube. Inert gases in the air can penetrate the glass, so a getter is placed in each vacuum tube to absorb inert gases entering the vacuum layer. But generally the amount put in can be used for 15 years. After 15 years, the vacuum degree will decrease more and more until it is no longer insulated, and the thermal efficiency will be very low. Good quality products can be used for 20 years, but thermal efficiency will decrease more quickly afterfrom 15 years old. As for small accessories, such as silicone rings, try to avoid the water temperature being too high when using the solar water heater. This way it will age more slowly. The way to prevent the water temperature from being too high is to use water frequently and refill it regularly.
How long do solar water heaters last?
The lifespan of solar water heaters is generally around 10 years, although some brands claim that their products can last up to 15 years, in reality. Use, due to the durability of the heating tube Sexual restrictions, safety risks will increase significantly after more than 10 years. The lifespan of the heating tube is generally this number of years. Continued use may result in a risk of electric shock, so it is recommended to replace it within the specified time.
The operating principleoperation of solar water heaters is quite clever. Sunlight passes through the structure of two layers of glass. One layer absorbs heat from the sun and uses vacuum insulation technology to almost isolate heat conduction and convection. Most of the heat is transferred to the water in the glass tube to heat it. . The heated water rises to the insulated water storage barrel, while the low temperature water enters the circulation from the backlight surface, so that hot water can be continuously supplied to water from the barrel to save energy.
In general, although solar water heaters are an environmentally friendly hot water solution, their lifespan is limited by their main components. It is wise to follow the manufacturer's recommended replacement intervals while ensuring safety. For principles and informationations, you can refer to relevant encyclopedias for complete information.
The lifespan of solar energy has a lot to do with the inner reservoir. Due to different processing methods, the shelf life may be as short as 3 years or as long as 30 years. years. Some brands will say that they can be used for 15 years when purchased, but they will be disposed of after 10 years of actual use, because the lifespan of the heating tube is only ten years. If it exceeds ten years, the safety factor. will be reduced and the risk of electric shock will easily occur.
Inner coating selection
1 Welding coating, whether you are doing argon arc welding, high frequency welding, manual welding, mechanical welding, Lifespan is generally 3-5 years, some are better 5-8 years.
2? Completely seamless coating, whetherinserting or tightening a rubber ring. Since the water inlet and outlet are at the bottom, the pipeline is easy to sway in the wind after insulation. also prone to problems. However, the service life is longer than that of welding. The inner tank can grow longer, about 10 to 15 years.
At present, the most advanced inner tank is also completely weld-free. However, the water inlet and outlet as well as the inlet and outlet ports are at the top of the inner tank, following the siphon principle. use solar hot water, just like a large water tank, with a lifespan of more than 30 years (the inner tank material should be 304-2B stainless steel).
In addition, there are two reasons for the short lifespan of solar energy
1 Vacuum tube
The vacuum tube is the main component of solar water heater. , and its quality affectsdirectly the overall performance of the solar water heater. Vacuum tube performance and quality are affected by coating technology and processes such as cleaning, coating, vacuuming and sealing. Inferior vacuum tubes have low vacuum degree, poor film stability, and are prone to aging and falling, resulting in rapid attenuation of heat collection performance and inability to absorb sufficient heat.
2 Insulation layer
The thermal insulation performance of the solar water heater is determined by the quality of the insulation layer. A good insulation layer has uniform foaming, high density, low thermal conductivity, high temperature resistance, high thermal insulation performance, and is stable and durable.
