LoicA Posted August 3, 2016 Share Posted August 3, 2016 HiI am studying the impact of panel degradation on the voltage and thus the voltage threshold loss (VMin 60°C).Where to find the value of the array voltage at 60°C the 20th year ?In the System window, the value shown does not take into account the degradation of panel power thus the panel voltage.In the Simulation -> Results > "Predefined Graph", it's possible to draw the "Distribution of array voltage" but it does not answer to my question and it's not easy to use.By using the hourly data I saw some values of voltage (see image enclosed) but two questions emerged :1/ Why the voltage is constant over the day ? Both the T° and irradiation are varying. The value of 596V is the VminInverter, is there a coincidence ?2/ Why some values of EGrid or PR are negative ? (not visible in the image enclosed).ThanksLoic Link to comment Share on other sites More sharing options...
