Weifang solar engineering capabilities and usability improvements have been improved since its inception, from the original to today's big drum tank corrosion and rust stainless steel and other materials of high tightness tanks, from the original collector low temperature only to 30 several times to the present 70 degrees, from the glass to the current collector plate collector. Since the introduction of the domestic solar energy and has been widely used in various fields has been. Since solar energy since the advent of functionality and usability improvements have been improved from the original to today's big drum tank corrosion preventive materials such as stainless steel high tightness tanks, from the original collector is low, the water temperature to 30 only a few degrees to 70 degrees today, from the glass to the current collector plate collector. Since the introduction of the domestic solar energy and has been widely used in various fields has been. So far the market share is still relatively large solar glass, this type of solar collector mode, low cost, good collection efficiency, fast heating water temperature and other characteristics, through the decades of market changes, solar glass clear has lagged behind the market, first, that it can not meet the required rate collector now living; second, do not adapt to some of the alpine region, glass cracking easily, frozen fried; third, high transport costs, materials belong fragile items; fourth, low resistance to natural disasters; fifth, the installation of beautiful enough, absolutely can not be integrated with the building, and even become the subject of criticism and some high-end residential pull-factor. In recent years with the advent of flat solar Some problems have been relatively improved solar glass on the market, there have been some atrophy; flat solar higher than the degree of integration of solar glass and beautiful buildings, became the immediate use more common way of solar collectors; however, the cost of flat solar glass is higher than that in some areas the ability of solar panel collector tube solar energy is not as cheap.
