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

Is this system sizing method sufficient enough to match load demand through the year, in which I don't. Someone who doesn't understand the in-depth PV system concept will think that this is the right way to size the system.

So, SAM can't design for more than 4 subarrays?. How do you then do your string design for a large rooftop with more than 4 roofs with different orientations?

Very illuminating webinar.

How do you enter microinverters (ex: IQ8) in the system design?

I've the necessary meteo data for my area, how can I create a corresponding weather file and run simulation in SAM

Great overview, many many thanks to the SAM team and NREL for bringing these amazing tools to the public.

hi, can I simulate my PV System from 2023 to uptill now in SAM..

¿No existe una versión en español?

Currently doing a research for LCA photovoltaic, Do I need to set a real life situation of a photovoltaic system to be compatible with SAM ? Or SAM itself is a simulation to simulate the real life situation?

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!

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

7 years ago! Can you update or make a new webenar

thank you for this informative presentation. a quick question: how do we input irradiation inputs?

At about 21:55, Dr Wagner talks about the scenario where the HTF pump is rated to the design power of the system. He says that, in this case, when the DNI exceeds the design-point DNI, energy has to be dumped from the system. This has raised two questions for me: 1. How would you go about dumping energy from the system? 2. What exactly does he mean by this? Is he saying the following: In this scenario, the maximum HTF flowrate that can be achieved by the pump is rated for when the DNI on the receiver is at design point. Therefore if/when the DNI on the receiver increases above the design-point, the pump is unable to increase HTF fluid flowrate further and therefore the HTF absorbs more heat/kg/s and thus the hot HTF temp will exceed the design temp (e.g. 565*C) ? It would be awesome if you could please answer my first question, and confirm whether I am understanding correctly in my second point. If my second point is even slightly incorrect, please could you correct me as I am not sure I fully understand the whole relationship between DNI/receiver flux, HTF flowrate and HTF temp. Any resources explaining the HTF flowrate control/design basis would be amazingly helpful. Thank you so much in advance!

where do i get the sensitivity and GHG models in SAM software

How can convert this excel data to epw format for energyplus simulation?

i had a problem when i chose manual dispatch option and chose the allowability to discharge to load at 100% rate .. the graph is completely odd and i and the system is not using the battery correctly ! .. if i reduce the rate f discharge to 10% which is in my case 100KW, the battery start pump larger energy to the system and the utilization of the battery is better ? so how can i solve this and allow the battery to discharge at 1C rate ?!

I just wonder, can SAM analyse off-grid solar+battery?

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.

Is the desired bank Power (kW) and desired bank capacity (kWh) equivalent to kWac peak per day and kWhac per day if I select "Set desired bank size" and select AC units for Battery Bank Sizing? Secondly, having ran your simulation, how do you show or read from your results that your system is providing 95% of the energy through the year.

Always after processing, SAM completely closes and does not output the results. Why?

Under Battery Sizing, are the inputs for desired bank capacity and desired bank power values per day, month or annum?. Secondly, what does the mean DC and AC, is it the indication of which side is the battery connected? Your SAM webinars and presenters are not explaining these.

My SAM version 2022.11.21 is unable to load the data, followed the above steps, not sure whats wrong

Where is the value of capacity factor and i also want to know about how to find out capacity factor

How to add utility database for those utilities that are not listed in the database. Or only US one being listed in SAM?

It's been four days but I still haven't received any emails.

How can I change the language of the SAM program to Arabic?

Given only the electric load (kW) data, how do you then do load analysis and PV sizing using the data?

Can we use this for offshore wind? Any additional considerations for offshore wind?

How to daunlod

I've received the email but I can't open the link or download any folder

is there a way to add new modules in this??

I want to design an off grid pv system without battery storage can i do it with SAM

are there any other websites that supply weather data sheets? maybe specific to wave datasheets?

where can you find the amount of modules to be connected in series and in parallel connection?

Thanks for the talk. I see we defined two costs for the battery, one in terms of $/kWh and $/kW. Would not be sufficient to define a battery cost only based on the former value?

I have queries, can you please link with me so that I can learn from you! In my research i am using SAM but i am confused and want to clear the queries. waiting for response.

Hi everyone, I would like to see how to import correctly field layout in order to investigate optical efficiency in SolarPilot ? Is SolarPilot appropriate to analyze small tower (100 kWe) ? Thanks
