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!

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: maximum inverter output was 68.60% of the rated value 2.626 So, I have to use a smaller inverter?

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.

I was so excited using this software trying to use a Canadian Solar utility inverter 350KW, which has 16 mppts...
Then I realized i cannot have more than 1 inverter with mppts, and if I do, it can only have 4 PPTS
I dont know how to go around this to simulate an 8MW solar farm
