It took me awhile to find a local PWS that was reporting solarradation. What I did was goto the “Wundermap” and check each PWS to see which values it was reporting. I eventually found a few somewhat close by. I looked at the historical data and found the one with the most consistent chart data. I wish there was a tool to find stations reporting specific values sorted by distance. You can probably try nearby zip codes as well if you don’t want to search around the map.
In the driver settings you can set the specific PWS as the location with pws:[Station ID].
