version but the problem I am facing is that when I selected a day like 22 Dec after simulation it is not matched for 2021 or 2022. My question is that how can I select the exact date of 2021/2022 to run the simulation for concern day? Thanks Regards,...

does not provide data for the current year. After this year, it will take some time for NSRDB staff to process new data for 2022 and add it to the database. Best regards, Paul.Hi Muhammad, A SAM weather file contains a single year of data. There are two...

have downloaded data for 2020. Would it mean it starts from Jan 1, 2020, and I will go for the third year to consider it in 2022? Or what does it mean? Simply I am working in Australia what will I do about it the link you send me gives me old data from...

Hi Julian, This message suggests that the piping model failed. The model is described in Section 2.5 of Wagner, M. J.; Gilman, P. (2011). Technical Manual for the SAM Physical Trough Model. 124 pp.; NREL Report No. TP-5500-51825. (). You may need to...

Hi Muhammad Irfan, To run a simulation for a specific year, you need weather data for that year. You can download weather data from the NREL National Solar Radiation Database (NSRDB) from SAM's Location and Resource page with the "Choose year" option to...

Thanks, Very helpful for me. If I want to simulate for the next 25 years, which means let's start from 2020/ 2021 to 2045/2046, then what I will do to do? Then from where I will get weather data to predict weather and solar generation, it's cost...

Hi Muhammad Irfan, Simulation results from a TMY file represent the "typical" power output you might expect from a system in the future based on the past. The NSRDB does not provide forecast data, but this is an area of active research. For example, see...

am using SAM 2022.11.21 for the first time, and I am not thoroughly familiar with all the concepts involved in the design. I am trying to run simulations to design a Concentrated Solar Thermal (Parabolic Troughs) facility to generate steam as feedstock...

Good morning Paul. Thanks. I have reviewed the chapter. Still, I still may need some guidance. Firstly, I changed the number of Field Subsections (It was 8 as recommended in NREL video for Molten Salt systems) to 6. The simulation ran this time, but...

Hi Julian, I tried the following with the first case in your file: On the System Design page: Design point DNI = 850 W/m2 Target solar multiple = 2 On the Solar Field page: Header design min flow velocity = 2 m/s (cold and hot headers) Header design max...

Hi, Paul. Thanks for your help. I adjusted the min and max flow velocities to 2m/sec and 3m/sec, respectively, solving the crash. After that, I made many sensitivity (Parametric) analysis runs. I obtained optimal values for DNI, TES hours of Storage,...

Good afternoon, Paul. I believe my previous post got cropped, and you could not see the last part of it. I am including again the error message still coming after any Parametric Run. At the bottom of the error message, you can see it is related to some...

Hi Julian, Those variables are outputs of the performance model that are also inputs to the financial model. The errors indicate that the performance model simulation failed. In the file you attached, the "IPH Trough Barranca MS 31Oct23" case has...

Dear Paul. Thanks again for your help on this subject. I have adjusted the Max Single Loop Flow Rate to 15Kg/s, and used 8 SCA / HCE per loop per your recommendation. Changes in the Desing Point DNI were unsuccessful since increasing the number above...

The charging behavior is a bug. The algorithm should be charging during those low cost hours. We will fix that for the Fall 2022 version of SAM: . Changing the discharging behavior would be an enhancement to the current model. SAM's battery dispatch...
