Advantages Of Flat Panel Solar Hot Water Project

- Jan 13, 2021-

Flat-panel solar water heating projects have actually been developed in China for more than ten years, and the technology is relatively mature. In comparison, the application rate of flat-panel solar hot water projects in foreign countries is very large. There will be some opinions on the Internet that the utilization rate of flat-panel solar hot water projects in foreign countries has reached more than 90%. We can't make a definite affirmation on this point, but what is certain is that flat-panel solar water heating projects are more widely used in foreign countries than vacuum tube solar energy. There are also many advantages of flat solar water heating projects. So, what are the advantages of flat-panel solar water heating projects?


First of all, the flat panel solar hot water project has better pressure bearing performance


At present, urban commercial solar hot water projects are generally central heating systems, and the pressure of tap water is high. This requires the hot water from the solar water heater to have a certain pressure, thereby reducing the gap between the water heater outlet and the tap water outlet The pressure difference provides convenience and comfort for users.


Since the heat absorbing plate of the flat panel solar hot water project collector is made of metal materials, the connection between the collector and the water storage tank also uses metal parts, so it can withstand the pressure from the tap water and the circulating pump.


Secondly, this feature of the perfect combination of flat-panel solar water heating projects and architecture is beyond doubt.


Flat-panel solar water heating projects are particularly suitable for building integration requirements. Due to its planar structure characteristics, flat-panel solar hot water engineering water heaters have flexible shapes and structures in the application of solar energy and building integration, and are not restricted by shape or size during design, and are easy to integrate with building components. In addition, its heat collecting plate is made of metal, which can be easily connected by wire knots and welding, which provides convenience for installation, maintenance and use.


Finally, the thermal efficiency of the flat panel solar water heating project is obvious


Because the evacuated tube solar collector is composed of a number of evacuated tubes, there are gaps between the tubes. When it is irradiated by sunlight, part of the solar energy is not received by the collector.


The flat panel solar hot water project collector 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 the average daily efficiency of vacuum tube solar water heaters by more than 6%.
