Modeling Utility-scale PV Systems in SAM

[@LuisAlbanes]

Hello again, I´ve already done my first run on a small project. I didn´t find exactly the PV and Inverter we have so I used the closest ones and I have this message at the end: Inverter oversized: ------The maximum inverter output was 68.60% of the rated value 2.626 kWac--------. So, I have to use a smaller inverter?

Hi there! I am evaluating the performance of an on-grid solar PV plant in Botswana, Gaborone, Currently, there is only 2017, 2018, and 2019 weather data. May I kindly request an update on the weather data. Thank you!

Hi Dear, Hope you are fine. Actually, I am performing performance and economic analysis for a 10 MW PV plant using UAE weather data. However, when I simulate it its Net Present Value is always negative but for similar 10 MW (built-in) USA weather-based data, NPV is positive. For both of the above projects UAE based and USA-based 10 MW solar PV projects, all the settings/inputs are similar like a number of inverters, modules etc. The only thing I changed is to enter the coordinates of UAE in the location tab to enter the UAE location and its NPV turns out to be negative but for USA USA-based location, it's always positive. (and there is a big difference between these two values) Can you help me rectify the issue, I think it might be something wrong when we load the UAE weather data? Hope to hear from you soon. Note: I have also posted in this SAM platform and also provided you both SAM files in my second reply.

Hello, for the shading calculations in the shade calculator, what software is usde to make a .s3d file please?

[@SAMDemoVideos]

The .s3d file is a special file used by SAM to store scene data for SAM's 3D Shade Calculator. Please post any follow-up questions on the SAM forum: sam.nrel.gov/forum.
