Ushered in flat-panel technology upgrade transit
Currently, a vacuum tube solar and the solar panel on the market share battle, is quietly brewing in the industry. Vacuum tube solar panel and solar energy, solar collectors, as the current two basic forms, the shift in the contradiction between the two determines the competition.
Solar Energy Co., Ltd. Deputy General Manager Liu Jie Sen said the rain, now flat solar antifreeze already solved the problem. Flow using copper pipe, cover the use of low-iron tempered glass production, the use of a secondary circulation system and antifreeze fluid heat transfer medium flat plate solar collectors can withstand large eggs fall from the sky hail from the days of combat, and not afraid of cold run, minus 30 ? still work as usual.
Norit relevant person in charge of solar energy, , frost and heat are the two core technologies with independent intellectual property with a real vacuum tube collectors compared to flat plate solar collectors for thermal insulation performance is poor. Specifically, solar water heaters can be divided into low, medium temperature, heat three systems, the low-temperature systems, flat-plate collector with vacuum tube collectors is almost the same, but the water temperature reaches 60 degrees Celsius, the flat-plate collector will encounter to the bottleneck, that is, at this time of the endothermic heat speeds up to speed and the mean temperature is difficult to continue to improve, while the vacuum tube water heater is not the problem, so the mild temperatures in the system, the vacuum tube will have more advantages.
To solar energy, general manager of Changzhou Sheng Mei Jianzhong that the solar panel does not have independent intellectual property rights, although many domestic companies claim that their flat-panel technology is self-development, but in fact most of the small improvement of foreign technology. Flat in foreign advanced technology of solar energy, rather than domestic. Plate to achieve the technical parameters, the vacuum tube will be more outstanding. However, with the accelerated process of urban development in recent years, multi-layer and high-rise buildings mushrooming of installation and use of the formation of challenges. As the multi-storey buildings and high-rise building roof area is not enough, should adopt the balcony-type or wall-type solar water heater, and vacuum easily broken, easily aging sealing gasket leaking, the balcony or wall installation, great security risk.
