What are the advantages and disadvantages of flat panel solar and vacuum tube solar?

What is the difference between vacuum tube solar and flat panel solar? After reading the most complete analysis, don't buy nonsense.

1. Advantages of solar energy: pressure-bearing, unique overheating protection function, anti-freezing and anti-freezing, snow melting and snow melting function, preventing solar energy "hibernation" phenomenon, perfect combination with buildings (balcony wall hanging and exterior wall hanging wall are widely used in urban high-rise buildings and high-end villas), easy installation, easy handling and installation, high thermal efficiency, large heat gain, large lighting surface, large effective heat gain area, less heat loss, stable water temperature, easy control, and long service life.

Disadvantages: poor heat retention.

2. Advantages of vacuum tube solar energy: safety, energy saving, environmental protection and economy. In particular, the solar water heater with auxiliary electric heating function is mainly based on solar energy, and the energy utilization mode supplemented by electric energy makes the solar water heater operate normally all year round.

Disadvantages: fragile, easy to break, high maintenance cost, no overheating protection function, no frost resistance, minus 20 degrees can not be used normally, no snow melting and snow melting function, winter snow days present the phenomenon of "hibernation", unsightly, inconvenient installation, can only be placed on the roof, increase the roof load, fragile, not suitable for building integration, not conducive to the use of urban high-rise buildings, not easy to transport and install, large gap between glass tubes, low effective heat collection area per unit, low heat gain, need to occupy more building space, easy to produce scale, It is not drinkable, falls into the water, is easy to cause water waste, and the water temperature is unstable and difficult to control.

At present, the types of solar collectors used in the domestic market mainly include: flat plate type, vacuum tube type, heat pipe type, U-shaped tube type, etc., the four types have their own advantages and disadvantages, and none of them is perfect and has an absolute advantage. The type of solar collector selected by the user should be selected according to the climatic characteristics of the installation location, the required hot water temperature and use.

For users in Guangdong, Fujian, Hainan, Guangxi, Yunnan and other southern regions that do not freeze in winter, it is very suitable to choose a flat plate solar collector, because there is no need to consider the problem of frost resistance in winter, and the disadvantage of a flat plate solar collector is not frost resistant, so it is used in the southern region, the shortcomings will not be shown, but the advantages of the flat plate type are very prominent: high thermal efficiency, metal tube plate structure, maintenance-free, 15-year life, and cost-effective.

Users in the Yangtze River and Yellow River basins, because the winter will freeze, and the winter temperature is higher than -20, so it is more appropriate to choose a vacuum tube solar collector, which can not only resist frost, but also cost better than heat pipes and U-shaped tubes, but the main disadvantages of vacuum tubes are: not pressurized, easy to form scale, easy to burst.

The flat plate only has advantages, such as high efficiency, beautiful appearance, easy to build, easy to build, easy to bear pressure, stable system, and no disadvantages.

Vacuum tube The disadvantage is that the tube is other ugly and the advantage is low.

Advantages of flat panel solar water heaters: First, it is especially suitable for building integration requirements. Due to its planar structure characteristics, the flat panel solar water heater is flexible and arbitrary in the application of solar energy building integration, and the design is not restricted by the shape or size, and it is easy to realize the combination with building components.

In addition, its collector plate is made of metal, which can be easily connected by wire knotting, welding, etc., which provides convenience for installation, maintenance and use. Second, it has high thermal efficiency. Because the vacuum tube solar collector is composed of several vacuum tubes, there is a gap between the tubes, and when exposed to sunlight, a part of the solar energy is not accepted by the collector.

The flat panel solar collector, on the other hand, is a continuous plane, and the entire surface of the collector can receive sunlight. Therefore, under the same daylighting area and sunshine intensity, the average daily efficiency of flat panel solar water heaters is generally higher than that of vacuum tube solar water heaters by more than 6%. Third, it has good pressure-bearing performance.

Since the heat-absorbing plate of the flat panel solar collector is made of metal material, the connection between the collector and the water storage tank is also made of metal parts, so it can withstand the pressure from the tap water and the circulating pump. At present, the centralized water supply system is generally used for urban water, and the tap water pressure is higher, which requires the hot water from the solar water heater to have a certain pressure, so as to reduce the pressure difference between the water heater outlet and the tap water outlet, and provide convenience and comfort for the user. Fourth, the performance is stable when forming a large system.

For some large-scale places, such as hotels, swimming pools, factories and other places, when using solar water heaters, many solar collectors are often required to form a large-scale water supply system. If a flat panel solar collector is used, the metal connection between the collector and the system is used, instead of the rubber and plastic parts like the vacuum tube solar water heater, the stability of the whole system can be guaranteed. Therefore, when building large-scale solar water heating systems, flat panel solar heat collection is often used.

In addition, due to the simple structure, convenient processing and easy large-scale production of flat panel solar water heater, it also has the characteristics of low manufacturing cost, low installation cost and long service life. Of course, the problems of high heat loss and anti-freezing in flat panel solar collectors also need to be further solved through scientific and technological innovation.

Flat plate collectors have many advantages over vacuum tube collectors.

For example, the advantages of the Solo Sunshine Tablet:

Long life, good combination with buildings, less overheating problems, high annual heat gain, stable performance Disadvantages: Relatively high, the heat collection capacity in winter alpine areas is lower than that of tubular Advantages of vacuum tubes:

**Cheaper, better winter temperatures than flat plates.

Disadvantages: Glass is fragile and has poor impact resistance.

In addition** is higher than that of a vacuum tube.

Advantages of flat panel solar collectors:

1. It is safe and does not blow up the pipe, and it is the safest product among all balcony wall-mounted solar water heaters.

2. The installation of flat panel solar collector is not restricted, and can be installed on the south balcony, wall, awning, window wall and other locations, and the water tank can be installed next to the balcony, toilet or air conditioning unit, which is suitable for various building design requirements.

3. Due to the simple structure, convenient processing and large-scale production of flat panel solar water heater, it also has the characteristics of low manufacturing cost, low installation cost and long service life.

Disadvantages of flat panel solar collectors.

1. High heat loss and anti-freezing problems in flat panel solar collectors. The "Tianzi" flat panel solar collector is antifreeze circulation, so there is no antifreeze problem, and the heat loss is also reduced to the minimum standard.

Advantages of vacuum tube solar collectors.

1. The heat loss of the vacuum tube solar collector is relatively low.

Vacuum tube solar collector disadvantages.

1. The vacuum tube solar collector is a water cycle, and there is a problem of freezing and freezing the vacuum tube in winter.

2. The vacuum tube solar collector will produce scale according to the different water quality after a long time, and the worse the water quality, the more serious the scale.

3. Due to the relatively high operating temperature of the vacuum tube collector, it is easy to explode and crack the tube when it suddenly encounters cold and heat.

Of course, it is a tubular type, with the simplest way to think, the collector plate can only be placed on the balcony, no matter how good there is no heat on the roof, and the life is short, generally about 5 years.

Flat plate collectors and vacuum tube collectors have their own advantages and disadvantages.

**In terms of flat plate collectors, they are slightly higher than vacuum tube collectors.

In terms of aesthetics, the flat plate collector is more aesthetically pleasing.

In terms of pressure, the plate collector has a stronger pressure capacity, which is generally about efficiency, and under the same footprint, the plate collector has a larger heat collection area and higher efficiency.

The two are the two main brand products of the solar water heater industry at home and abroad, the application proportion of flat panel solar energy and vacuum tube products in China's solar energy market is very different from the situation in developed countries, and even completely opposite to the European and American markets, more than 90% of the products in the European and American markets are flat panel solar products, and less than 10% in China. Which is better, flat panel solar or vacuum tube solar? As two equally divided application systems in the field of solar thermal energy, the performance of flat plate and vacuum tube has its own merits, the following comfort 100 network will take Jiesen flat panel solar energy as an example, carefully analyze the comparison of flat panel solar energy and vacuum tube solar energy.

Each has its own advantages, the durability of the plate is good, and the integration effect with the building is good, but the water temperature in winter is lower than that of the vacuum tube.

Vacuum tubes have a higher heat collection temperature, but are not as durable as flat plates. One is damage, which is less common, mainly because the vacuum degree is gradually destroyed over time, and the thermal insulation performance of the pipe will decline.

Suggestion: If you are in the north, you can use a vacuum tube, and you should use a large factory.

The temperature in the south is relatively high in winter, and if the sunshine is better, you can use a flat plate.

Quite a lot of European tablets are used.
