Power(W/m^2) versus Azimuth Angle (degree) was created by ayedh_alqahtani

Dear Dr. Paul,

I downloaded the latest version of SAM (2013.1.15), and I would like to get the curve that describes the Power (W/m^2) related to the Azimuth Angle (degree), for one PV module (any module), located in Columbus, OH. Similarly, I want another curve for the Power with the elevation angle. Could you please show me how to do this?

Thank you

In the incident-radiation-vs-azimuth.zsam file (ZSAM 3 MB) , I set up a parametric analysis on the azimuth angle with values between 90 and 270 degrees.

On the Results page, click Graph, and you should see a line graph of total annual input radiation (kWh) vs azimuth angle. You can convert the input radiation to W/m2 by dividing by 8,760 hours and the array area in m2.

If you click Tables on the Results page, you should see a table of hourly incident radiation (kW/m2) values for each azimuth angle. You can export that table to Excel (click Save as CSV or Send to Excel), sum up the 8,760 values in each column, and create a graph in Excel of the totals.

Best regards,
Paul.
