tshaw26 Posted October 14, 2016 Share Posted October 14, 2016 We are being asked to provide a modeled Irradiance Weighted Module Temperature for some projects that we are working on, and have a few questions that have come up:- Is the Tarray that is showing in PVsyst the same as the Irradiance Weighted Module Temperature? If not, where can I go in PVsyst to get the information?- The portfolio consists of several smaller projects, all located within a few miles of each other. Some of the sites consist of older modules that are about 3 years old. Because of this, we are incorporating a 3% LID loss, while the sites using the new modules do not have this loss calculated in. I have noticed after running the simulations that the sites using the new modules are showing almost 10 degrees cooler on the Tarray. Is this because of the lack of the LID loss, or does it have more to do with temperature coefficient? Any insight that someone can provide would be greatly appreciated.Thank you Link to comment Share on other sites More sharing options...
