The NASA Power data set gives access to daily or monthly temperature averages for any point on earth. This would be useful for calculating PV output given the reliance of efficiency of panels on temperature, however it seems to me that the peak solar irradiance would coincide not with the average temperature--which includes an average from post-sunset hours too of course--but with the maximum temperature.
What I am looking for is a means to re-calculate the average temperature and skew it to the maximum, but I have only a minimum, maximum and mean temperature. I have a feeling that I would not be the first person to do this for a PV application. Is there some kind of established standard/protocol for doing so?
Thank you!
a daily profile of temperature and solar irradiation are not easy to find in detail measurement i advice you to use your setup and prepare your materials as senors and data acquisition system to get what you looking for
Dear Abed,
One way to overcome this would be to use reanalysis data (such as one available here: http://www.soda-pro.com/web-services/meteo-data/merra ) and for irradiation, I would refer you to that one ( http://www.soda-pro.com/web-services/radiation/cams-radiation-service ) they both come with hourly values. However, it is advised to juxtapose them with local field measurements.
Alternaively, maybe you can use TMY data from http://climate.onebuilding.org/
this website provides weather data by hourly.
