Did you buy vacuum tube solar energy? Vacuum tube solar energy, as the name suggests, is composed of a double-layer sleeved glass tube. Water or antifreeze flows inside the inner glass tube. There is a heat-absorbing coating on the outer surface of the inner glass tube to absorb the energy of the sun. Between the two glass tubes The interlayer between them is evacuated to maintain heat. As we all know, glass tubes are very easy to explode when suddenly exposed to cold or heat. Vacuum tube solar energy cannot avoid this shortcoming. So I guess your solar panel leaked because the glass tube exploded due to cold exposure.
Relatively speaking, there is a type of flat-panel solar energy on the market now. This type of solar energy is very suitable for large-scale hot water systems. It has high water production and can overcome the problems of vacuum tube explosion and tube cracking. instability problem. Beijing Joyoung Industrial Company is a company specializing in solar water heating projects.

First of all, in terms of products, the company's flagship product - all-copper plate core, ultrasonic welding flat-plate solar collectors, has always been in a leading position in the country in manufacturing and production. Flat-plate solar collectors have the characteristics of simple structure, reliable operation, high thermal efficiency and strong pressure-bearing capacity. However, with the continuous advancement of solar energy technology and the fierce competition of solar products on the market, flat-plate solar collectors are facing severe challenges. In order to manufacture domestic first-class and competitive flat-panel solar collectors, Joyoung has made continuous technological improvements in product structure design, material selection and processing. On the one hand, Joyoung uses high-quality materials such as all-copper plate cores, aluminum alloy frames, and low-iron tempered glass for its flat-panel solar collectors. It has introduced the first domestic ultrasonic welding equipment for flat-panel solar strips and built a 100,000-square-meter flat-panel solar collector. It has realized large-scale production of collectors and took the lead in conducting system pressure tests on flat-plate hot water systems, which has improved the overall quality of the product. On the other hand, our company and the National Housing and Living Environment Engineering Technology Research Center have jointly established the "National Residential Engineering Center Solar Building Jiuyang R&D Base".
