can I have Incident beam solar radiation without epw file ?

I don't have the epw file for my location. I want to calculate Incident beam solar radiation on external surface . I think if I had the coordinate of my location I should be able to define simple sky model for that location . the location specification such as pollution or sunny days are not important for my run,I want to compare different models base on same sky condition (sunny sky) in location that I haven't the epw file for it . can I changed the coordinate inside an epw file for my location and set energy plus to use a simple sunny sky model that other weather data doesn't effect my calculation ?
