When investing in solar technology, 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" 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 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 International patented interference film coating 3 Hi” vacuum tubes use 3 systems to ensure the most effective heat absorption. This included a AL-N/AI layer but also a separate aluminum and copper layer. The added layer conduct heat better and also stabilize the coating allowing for a much longer lifespan of 20 year or greater.

Test Drive one of our solar systems and you will quickly see the difference a powerful "engine" makes. See below for comparision on SunRain performance versus other leading evacuated tube suppliers.

SunRain Versus the Competition

As the worlds leader in Solar Vacuum tubes, SunRain clearly has done so by providing quality prodcuts at affordable prices. SunRain Evacuated Tube Solar Collectors are the most cost-effective collectors on the market – they offer the best performance at the best price – THE BEST VALUE AVAILABLE! SunRain Evacuated Tube Solar Collectors out-perform all major competitors – and are available for hundreds of dollars less.

Based on actual German Keymark Testing and SRCC, here is how the SunRain performs against the leading vacuum tube major competitors:

When comparing the BTU/$ values for SunRain Evacuated Tube Solar Collectors and Apricus’ AP-20 Solar Collector, it is clear that SunRain Evacuated Tube Solar Collectors are the better value – hands down. And these figures are even more staggering when compared with the selling price of Thermomax’s Solar Collectors.

These numbers are clear as day – illustrating the tremendous value of the SunRain Evacuated Tube Solar Collectors compared to the leading national competitors. If you want to make the smart decision and choose the right solar collector for your home or for your dealership/installation business, SunRain Evacuated Tube Solar Collectors deliver the performance, quality low price and value you need!
