I would like to calculate PV output for 100 sites for one year using hourly solar irradiation and temperature data. Can anyone suggest how I can use a software (e.g. PVSyst, RETScreen or similar) in batch mode or otherwise automate the process?
If your solar cells are the same throughout all sites then only the operating conditions will vary which is the G the incident solar radiation and the temperature. It is so that the photo current is strictly proportional to the G. Also here is fairly accurate model for the variation of the solar cell output power with temperature. In this case you do not need to calculate the output power in very site. You need to calculate it in one site only. And then use illumination and temperature model to calculate for the other sites.
You can also sample the sites and calculate only for a limited number of sites covering the whole variation range. and then use interpolation to calculate for the intermediate sites and then check some of them.
You can use any simulator to calculate Pom given the solar cell structure, illumination and temperature.
As an example for the CAD tools please refer to the chapter in the link: Chapter Solar cells and arrays: Principles, analysis and design

Dear Diane,
You can use Liu and Jordan's model and follow the procedure in the following article. If you have solar irradiance (global and diffuse) and ambient temperature hourly data for the entire year, you can write simple code and easy to compare the 100 sites.
