PV*SOL

Hello, I just purchased the PVSOL Premium and need to design 3 different arrays in one project, is this possible, without setting up three different projects in the software? Thanks, Eddie

Do you know how to find the best angle and the best orientation for solar panel according to the location ? For example, I am in Bogota, and I want to know what is the best angle and orientation for maximizing the energy along the year. Or for maximizing the energy during the worst month of the year. And so on ? Do you now if there is any function in PV Sol and if not, do you know if I can find it on internet ? For example, that's easy for europe and africa with this webpage : http://re.jrc.ec.europa.eu/pvgis/apps4/pvest.php# But for South America, I didn't find something similar yet. Thanks for your help !

Greeting. I´m Edwin From Cali, Colombia. today download Pv*sol premium trial for test the software. i Try made my roof and i can not make it. i read help file with pv*sol software but i don´t understand how i can make 3D roof i see you tube videos and i don´t see step by step how to make 3d Roof. Thank, Edwin Vidal evidale@gmail.com

I would like to reduce the inverter number as much as possible when I use the inverter configuration...is this possible?

Hi friends: I would like to ask about some improvements in the Dimensioning Plan. As you can see in the picture below it is almost impossible to understand the measures for the pv generator. Is there a way to improve that? I think is a very good tool for the design and it is a shame that unusable... Best regards, Boris

Hi guys, I´ve a question about the info in the Configuration Check window. If you see the next image, there is a U0 = 1024,3 V above the maximum level, but the temperature for that U0 is -283°C..., is that correct??? Regards, Boris.

Hello, I have developed my first design using 3D Design feature and so I am really not acquainted with this features on the report. I did some tests and no matter what the spacing between rows I apply I always get the same "Yield reduction due to shading", in this case 16.3%, this parameter is calculated based on what? My initial row spacing calculation was 1.64 m and effectively it had some partial shading on the pannels, shade frequency about 2.7%, I have now increased the distance up to 4 meters, there is no shading on the pannels and I still get the same results. I need to justify to the customer how this Yield reduction due to shading is calcula…

I have a question I have a pv sol premium 7.5 can I upgrade to 2016 with the same license ?

Has anyone had a try of PVsol 2016? All the new features seem unstable and hard to use. I was told that 2016 would use Sketchup for 3d modelling which would have been amazing. Is it possible to import buildings from Sketchup? Hopefully the glitches will get worked out but even then I don't think the new features look useful. James

Dear all, Hope this message finds you all well I would like to ask , what factors affects the specific yield for the same location . as what I did try is to choose different panels and compare the specific yield . and some results were just making no sense some panels were have better efficiency , better temp. coefficients and still have lower specific yield So it will be helpful if one of you guys try to explain what really affects the specific yield calculation Best regards, Ahmad Elghobashy

Hi, The performance ratio is defined as "a measurement of the energy losses that occur within the system in comparison with the system's optimal operating conditions. The actual solar energy produced is measured against the nominal output. The nominal output is calculated from the irradiance onto the tilted PV surface multiplied by the efficiency of the module under standard test conditions (25 °C, 1000 W/m²). The Performance Ratio is calculated: PR= (PV Array Energy (AC) - Stand-by Consumption)/(Max. possible PV Array Energy )" This probably should be verified by dividing the Grid Feed-in (or PV energy (AC)...) value by Rated PV Energy. I see some 5-6% more valu…

Hi Everyone I had been working a lot with PVSol Premium 7,5 (R4) with the 3D, but today the program started with some problems during the View Presentation process. The thing is the programs stays in a loop..., and the view presentation doesn´t work... The same thing ocurrs if I use the PVSol Pro Standalone tool. When I want to simulate the system, the program has the same problem. It could be a program failure or could be another problem? I don´t know if it is possible to reinstall the program, because I´m very concern about the problem and I´ve been restarting the computer a lot of times. Thanks and regards, Boris.

Hi, I would like to conduct an analysis of fixed tilt Photovoltaic array. I need a weather file for particular location. It can not be found in the PV*SOL Climate data. But Meteonorm has it. The problem is that this Meteonorm weather file does not contain data about snow depth nor albedos. I was wondering if I could approximate this by somehow defining an albedo to be 0.6 (ground covered with wet snow) in cases when air temperature is bellow some value. Which value would that be? Something bellow 0°C. Basically when this air temperature value is present, there is snow on the ground, and when it's higher than this value, there's no snow. RETscreen advices using 0.7 al…

Hi. I was wondering how does the PV SOL apply the light transmission factors (degrees of transmittance)? I understand that when it comes to solar thermal systems and T SOL, the light transmission factors are used to reduce the amount of solar radiation passing through a tree object. But what about PV SOL? If I understood correctly when checking for horizon shading for PV systems, it is shading of the actual AC output that is taken into account, not the solar radiation. That is: if certain portion of the horizon is shaded by an obsutrction tree the AC output that this certain portion of the horizon yields is subracted from the overall annual AC output. So how are thes…

After creating an elaborate design, I go to export the presentation and I get the following message: "The presentation cannot be created" Why am I unable to get my report? Richard

Dear Sir / Madam, For battery system,I would like to model a system of 1 SMA Sunny Island Inverter 8.0H and 24 units of Hoppecke 24 OPZV 3500.. What I see available at the moment is SMA SI 8.0H - 11 set LG Chem 5,0kWh and SMA SI 8.0H + Akasol neeoQube. Is there a way for me to modify the existing components to suits my objective ? Thank you.

Hello madams and sirs, How can I calculate for the total land or roof area used ? and not the pv generator area ? what I mean is the total area including the panels cleareance and the eadges and the walkways in between strings Regards, Ahmad Elghobashy Egypt

How we can calculate optimum angle for our panels, can you share with me formula of this calculation. I know we can see it in old versions of pvsol.

Good morning I have got the following question: is it possible to size a power plant with batteries and auto-consumption, but injection of the surplus energy on the network? Kind regards

Hi everyone: My question is about how to get the V-I and P-V data (and curves) from a simulated PV plant. Is there a way to get them, besides the energy output? Best Regards, Boris

To understand the impact of shading I have run the same system with and without shading. The reports show a slight increase in yield with shading, The shaded system shows a loss from shading more than made up for by increase in low light performance. The seems wrong, has anyone else experienced this? any tips to understand why this happens?

Hello, The company I work for has bought one license for PV Sol 7. However, we want to remove it from one computer and install it on another. How can we do this?

Hello, My name is Ahmad Elghobashy from Egypt I do have a question and don't know what to do , and I think maybe you can help I have a string of 20 modules of Jinko solar panels JKM 310Wp now from the data sheet the open circuit voltage is 45.9 V So the total string open circuit voltage is 918 V now in the system check I get 1018 V So the max. allowed open circuit is exceded but I don't know why there is a 100 V over the stated in the data sheet

I have a project where in one roof , I have two types of installation one array should be mounted while the other is roof parallel . And I did the first from mounted assembly , then when I add panels from module coverage I get an error messeage saying that I can't use both on the same mounting surface what is the solution for that problem ? Or how can I cobine both on one roof ?
