The Working Principle of Sun Rain Solar Vacuum Tube Collectors
The solar collector acts as an engine of any solar water heater. A solar vacuum tube is the most efficient solar power production system; but was more costly than flat panel system. With the immense popularity of solar energy and modern manufacturing techniques, the solar vacuum tubes cost less while ensuring the greatest return on the investment. Working principle of SunRain solar vacuum tube collector The working principle of solar vacuum tube is simple. It works same like a coffee thermos. A solar tube comprises of two layers of glass with vacuum in between the layers. The outermost layer of the solar tube is actually the Borosilicate glass that has very iron content and allows around 98% energy to pass through. In fact the innermost layer has very special coatings applied to it. The SunRain solar vacuum tube collector available at Northern Lights uses a patented three layer process that ensures a coating to absorb enough solar energy while withstanding
