SPP brand solar thermal collectors
Testing SPP solar thermal collector products is very important, as is testing our competitors products. Real outdoor testing over a period of time and under various weather, temperature and sunlight conditions is just as important as any indoor testing that can be done under artificial sunlight. Of course all SRCC-Certified collectors undergo indoor lab testing and under these conditions SPP collectors have no competitor with higher collection values.
We are also happy to report that our real-world outdoor tests confirm the superiority of the SPP collectors, while allowing us to continually improve them. We never stop testing. Here are some images from the outdoor lab.
