SolarWaterHeating. Compare Evacuated Tube Collectors Vs. Flat Panel Collectors Comparison. The solar heating collector's job is simple – it sits in the sun, absorbs the heat, and transfers it to where you need it.
To do this efficiently, solar heating collectors need to absorb – and retain – a large volume of sunlight every day. There are two main technologies that have both been time tested and accomplish this, and as a result there has been a practically endless debate over which is considered “best”. These two main technologies are the Solar Flat Panels, and Solar Evacuated Tubes. Solar Evacuated Tubes, Solar Vacuum Tubes. "3-Hi" Solar Vacuum Tube Technology Solar Evacuated Tubes - Solar Vacuum Tubes When investing in solar water heaters, it is important to ensure the "engine" you select is the most powerful and the longest lasting made.
This if why we use SunRain's patented "3-Hi" solar vacuum tubes. The absorbing coating found on the inner layer determines how efficient the vacuum tube will operate. The method and material of this coating will also define the life expectancy of the solar vacuum tube. How do solar panels work? - Richard Komp.
