Hello, In short, yes. However, SAM's 3D shade calculator only works with up to 8 strings per subarray. To illustrate this, I added a third attachment to your original post. It is a SAM file with several cases described below: Original This is the...

Dear Joe, As you note, the variable is an input to the compute module. And, in the desktop version of SAM, the variable is shown in the user interface on the Solar Field input page with the label "Actual number of loops," where it is a calculated value...

Dear Abubakar, SAM does not model hybrid power systems. You can use the Combine Cases macro to combine the power output of two different systems and use that generation profile with a single financial model to approximate a hybrid power project. UPDATE:...

Dear Paul, I had installed the SAM software in Windows, but when I try to open it, an error message appears immediately. I tried to resolve by reinstalling SAM latest version 2018 as well as previous version 2017 also but there are no changes, the same...

Hi Darren, For SAM's Detailed Photovoltaic model, each case in SAM supports up to four subarrays, so it is not possible to define shading scenarios for more than four subarrays. Depending on the system you are modeling, you may be able to use the...

Hi Bud, There seems to be a bug in the capacity factor calculation for the Geothermal model. We will fix this issue for the Fall 2021 version of SAM. As a workaround, please use this LK script to calculate the correct value. To use it, click Open script...

Thank you for the response Paul, I have tried to put together another file to better illustrate the issue I am having. After further tinkering the issue I am observing appears to be related to the "inverter thermal derate DC power loss (kW)", which does...

Dear Mr. Paul, Thanks a lot for your reply. I have other questions in my mind. If you can help me, I will be grateful. 1) Which is more reliable method to use, the Single Owner LCOE calculation or the LCOE calculator? Which of these two methods is used...

Hi Joel, That configuration requires modeling each building as a separate case. You could model the combined system using the Generic System model, which allows you to provide a generation profile (hourly or subhourly) as input. To do that, start with a...

Thank you Nathan. I will discuss this with the development team and let you know what we decide. For now, you can at least find a list of all of the URLs that SAM accesses in the webapis.conf configuration file, which is in the same folder as the SAM...

Paul, Thanks for the reply, the effective tax rate hadn't occurred to me but I see that it does make sense as with lower operating costs, tax liability will increase. I do work in windows 8, and tried the new Send to Excel with Equations function;...

Dear Pam, Yes. As long as the scripts are in the same SAM file, you can call a function from one script in an other with the 'use' keyword. For an example, see the sample file SamUL Script Samples (from the File menu, choose Open sample file, and then...

Hello Yes, SAM project files can be shared. For the project (containing the cases) you want to share, go to File and choose Save As... Save the file as type *.zsam. Send the *.zsam file to your colleague to share the project. Note that if the *zsam file...

Thank you for your comment, Paul! Well, I used a random .csv file from the list which is in the program (from different regions US I guess) as a base file in the TMY3 creator, there I pasted my data into the table and wrote the right...

Paul, I've been working on this rather basic residential system off and on for quite awhile. I feel reasonably confident in all my input data. Although string sizing and inverter matching are subjects that need additional study on my part. Also, need to...

Hi I have been successfully been using SAM for several years on the same computer, windows 7 64bit. I have just installed 2014.11.24 and was trying the default PV models included in SAM. After I run the simulation and start looking at various outputs,...

Dear Brian, Unfortunately, the "send-to-Excel" functions do not work in OS X because they rely on Microsoft's OLE technology, which OS X does not support. The Excel workbooks that SAM uses for the send-to-Excel are available on your Mac, so you can at...

Is it possible to model hybrid power systems in SAM? For example, a system that combines PV, biomass gasification, and wind? No. SAM models single technology systems. However, you can use the Combine Cases macro to model a project that consists of...

Dear Brian, I assume you want this measurement for a Google Earth image to use as an underlay for the photovoltaic 3D shade calculator. As you know, by default SAM can automatically load Bing map images from the coordinates you enter. If you want to use...

Hi Brian, Thanks for pointing out this limitation. Unfortunately, in the example you give, SAM uses 0.8 rather than 0.84. We'll fix that in the next update. UPDATE (AUG 20 2015): SAM 2015.6.30 r2 FIXES THE DECIMAL POINTS ISSUE. HOWEVER, THE "TERMS OF...
