mlong87 Posted September 25, 2014 Share Posted September 25, 2014 Hi,Is it possible to do the P50 and P90 calculations in a stand alone system. For example i need the system to be 100% reliable, year on year. I use currently Meteonorm data, which is averaged so there is a chance one year could under perform. Usually what is done is the system is over sized, so the battery autonomy will always save you in the case of under production but it is also the most expensive part of the system. Is there anyway to model this variability so i can optimize my battery size?Thanks,Matt Link to comment Share on other sites More sharing options...
