SolarWaterHeating. Compare Solar Thermal | 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. As an American manufacture of solar heating products, Solar Panels Plus has tested, designed, and supplies both flat panel and evacuated tube systems. Flat Panel Collectors Flat panel collectors have been on the market and in use since the early 1900's, and are one of the most time tested and well known technologies. Evacuated Tube Collectors Evacuated tube collectors are a slightly more recently developed technology, introduced to the market in the 1970's. Evacuated Tubes vs. Cost Performance Design.

"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. Most vacuum tubes use a hi-tech reactive sputtering process to coat the inner tube. Most commonly this coating is made from an aluminum and aluminum-nitrogen coating (Al-N/Al) which is the primary absorbing coating. SunRain's solar vacuum tube technology uses an International patented film coating called “3 Hi”.
