Weather Data

Are you looking for weather data to use with SAM? SAM can automatically download weather files from the NREL National Solar Radiation Data base (NSRDB), which covers locations in the Western Hemisphere from roughly 20° South to 60° North, including the continental United States, Hawaii and southern portions of Canada and Alaska, Caribbean, Central America, and northern South America (including most of Brazil). The NSRDB data also covers South Asia and parts of Central Asia, China, and Southeast Asia.

"Failed to geocode address"

When using SAM's "Download a Wind resource file" the weather data file will not download and spits out "Failed to geocode address". Even when I try to download the default location it provides (Denver CO) it fails to geocode the address.

What is going on with my SAM? What is the work around? I have tried troubleshooting SAM many times and the same problem persists.

Weather Download Macro Not Working

When I try to run the "Download Weather Files" macro I get the below error:

Macro did not finish.
[140] runtime exception at line 140: access violation: expected array for indexing, but found null

Any idea what would cause this?

Any thoughts on what would cause this? I am working on a project assessing the solar PV potential of 80 sites and it would be very useful if I could run the macro.

Weather Data from POWER Data Access to SAM?

Hello everyone, I have a problem here, since my Country does not have weather data on the format SAM uses.

So I was wandering if there is any way to use POWER-LARC data on SAM.

Does Anyone have done this?

Weather files for Australia gone

I have just upgraded System Advisor Model to the latest 2018 version and I am no longer able to access any Australian weather data.

This is an incredible shame and has rendered SAM useless to me. Given I can go online to PVWatts and simulate PV generation for a significant number of locations in Australia, the inability to do this in SAM is mindblowing. I guess I could pay the $250 to purchase the ASHRAE files, but maybe i'll just have to invest in a more functional tool.

Please advise if I'm missing something here - I really hope this to be the case.

Trouble selecting weather Data

I have already downloaded the update for the SAM 2018.11.11, but still i can´t select a weather data for my location, not the ones that i have downloades previusly, nor can download them directly from the sam location and resource, when i try to do any of the above the program starts updating info in the latitude , longitude, time zone, elevation... to finally leave the program.

How can i fix this issue?
