Weather File Downloads Issue

Weather file downloads for SAM's solar and wind models are not working as of October 12, 2022. This will be fixed in next version of SAM, which we hope to release in November, 2022.

For wind models, the workaround is to use the latitude and longitude option (you can right click a location in Google Maps to find its latitude and longitude):



For solar models, a workaround is to download files directly from the NREL National Solar Radiation Database (NSRDB) website. Here is a short video demonstrating how to do that:



For a detailed description of the problem, see github.com/NREL/SAM/issues/1186.
