negative energy

Hi,
I performed a simulation for a parabolic trough power plant. I get a negatives values for annual energy,capacity factor, NPV,and
Internal rate of return (IRR) NaN
Year IRR is achieved NaN
IRR at end of project NaN.

That suggests there is something wrong with your inputs, or with the data in the weather file.

Could you email me a copy of your .sam file and weather file using the contact form?
