Dear Paul,
I am simulating a CSP plant with tower technology in Chile. I use the page
solar.minenergia.cl/inicio to download climate files compatible with SAM (attached an example). When I simulate PV technology there is no problem, but when I want to simulate a CSP plant it cannot calculate the generated power and they only give negative numbers, something that does not make sense. I'm sure the problem is with the weather file, because when I use a file that comes in the software, there is no problem. This problem has always been? or are you having a recent problem? Apparently the problem is only with concentration technologies.
Thank you very much in advance for your kind reply,
Francisco
