Solving Temperature Issues Found in Fresnel Reflecting Solar Concentrators
However there is one catch, the prospect wants greater assurance that the materials you have selected will stand the test of time...and they want the results within the next four months. In particular, they want you to further validate the durability of plastics used in your product when it is subjected to extreme levels of direct UV light.
True enough, the materials used in your formulation have already been subject to numerous and extensive UV light tests in a state-of-the art xenon weathering instrument. And while the manufacturer said they were impressed with these testing methodologies and corresponding results, they also want an outdoor "real world test, just to be sure." Of course you say "no problem" and make arrangements to get back in touch over the next few weeks to let them know what you're doing.
