PV*SOL

I have a fairly simple PV setup that I'm trying to connect to inverters: After picking the inverter that I want to use I let PV*Sol work out how to connect the panels. However, its results are not satisfactory: This is an ~800 kWp system using 110 kW inverters. It shouldn't take more than 8 of them. And definitely not 15, There are no suggestions with fewer inverters, others use 16 or 17, How do I get the software to use the inverters more efficiently? Nothing in the settings seems to be related or have any effect.

Hello, I wanted to compare the yield of vertical PV with conventional PV on a given roof size. The daily yield curve of vertical PV is usually m-shaped, which means two peaks in the morning & evening and a through around noon. After the simulation I compared the yield curve of several days. Besides the expected curve I also received several days where the yield curve is the same as the conventional one. I can't explain it to myself. Maybe you guys can. Thanks in advance. Best, Philip

Is there anyway to copy a building with modules or roof objects on it? I was working on a project recently and basically had 9 identical buildings with same roof objects and panels. I was able to copy the building since they are same building but on each buildings i had to place the roof objects and modules which takes so much of my time as it was over 10,000 modules. If there was a way to copy buildings with roof objects and panels on it that would be helpful.

Hallo , why is it not possible to select the new battery lg Resu flex ? Best regards. Oliver Stieg

Hello, I was facing issues with battery configuration, 1) there are two inverter in part list , i need only one inverter and battery . how to remove the no 2 row ? 2) how can i chose my inverter and battery separately for eg : sma battery with solis inverter

Hello Is there a function to calculate ballast for solar cells on a flat roof?

Hi, just wondering if anyone knows how to change the inverter numbers once they have been configured, currently have 16 inverters and not in any sort of of order, plus I have a number 17 and '15' is missing. We use PVSOL for design reference for all our drawings and would be great to have inverter numbers that make sense. Thanks Tim

Hi I have a setup with 4 inverters, and the feed-in to the main panel must be max 200A in total. The inverters are all same model and size, and each at 70A. So the total are 280A How do we set this up correct in PV sol? Thanks,

Hi, Here in Denmark we have all the spot prices readily available from a public API. I trust you have the same in DE? So why is the PV calc's base on fixed, manually entered values??? With more and more solar and wind on the grid, prices seem to be very low when the solar panel are producing at their max, often even negative. That gives a poor ROI. It would be nive if PV*SOL could use the real data and provide the true picture, so we don't have to invest in solar blindly or based on overly optimistic report.

Is it possible to use different FV modules on a single 2D project? I need it for a plant revamping project/simulation. Kind Regards

When I import the OBJ file into PVSOL, the 3D model has no color. What to do?

Is it somehow possible to add more consumption data in a pv*sol project and define which part of the pv plant is connected to a specific consumption? e.g. I am working on a project where a large company wants a solar system. They have 3 transformer stations, each with its own electricity meter, from which I have data. Due to the Danish regulations, I must have distributed their solar system on their meters. Can you define which part of the total plant in a pv*sol project belongs to a specific consumption? Or do you have to create a project for each sub-plant so that pv*sol does not see it as a plant with a total consumption?

Is there a way to set how the battery should be charged, e.g. ; battery first or charge with 30% solar energy the rest for the house/grid.

Hi, So from the images below you can see that on the report I have a Spec. Annual Yield of 1116.18 kWh/kWp. (521,192/1116.8= 466.76kWp) Does this Spec Annual Yield take into account the performance ratio as 95.85%? So if the PR was 100% would the Spec Annual Yield would be close to 1164.5? But on the PV System Energy Balance I have different to figures as below: Best regards Carl

why first year savings in financial analysis is different first year electricity savings in cashflow table whereas start of operation is 1.1.24. and what is the algo is used in the cashflow table 3mw, 3382kwp 21.7.23 2nd.docx

Every time when Valentine publishes a upgrade my home location changes to Germany and I loose all the climate data locations I have created. Why does Valentine do that?

Hi, i'm relatively new and on my way to do PV planning professionally. I thougt i'd try a a 3D photogrammetry aproach to do the planning in a way like create a bunch of serial photos via drone (DJI Mini 2 in my case) of the object use Agisoft Metashape (or Pix 4D) to build a textured mesh export the OBJ and use it in PVSol Pro get an awsome looking model for the offer 😅 Reason for this is that im located more on the countryside, Google Image quality is typically pretty bad, and most of older houses have no plan available. And if you calibrate the model with some known distances the accuracy of the 3D model is very good. 1-2cm detail…

Any ideas why this would happen after importing a model. The model was created with 3DF Zephyr and the original model is clean. It doesn't seem to do this with OBJ files from other software. The same file loads in Cloud Compare with no problem.

Hi in the below project there are 174no X 125w thin module in the centre which is around 21.75kw. so i want to configure to any 20k inveter ( Solis , Growatt , SMA, Giv energy ) Could you please advice ? if you could send a screenshot of configuration it would be great. Thanks Strand 49.83kwp trial.pvprj

Hello, was wondering were there any possible solutions to this problem, how to allocate more memory also i have seen before nvdia settings setup tutorial somewhere but cant find it anywhere (Best settings) could you link it ?

Hi all! I want to ask a question to which I have not found an answer for myself. Maybe someone can explain what's wrong? When simulating a 2 MW solar power plant with azimuth 180 the program produces 1625.19 kWh/kWp, with azimuth 210 the program produces 1680.12 kWh/kWp. How is that even possible? Such an effect on both bifacial and monofacial modules. In other programs, the calculation shows the deterioration of generation with any change in azimuth. The difference is more than 3%, so this question is very important. Thank you!

Hi, Can anybody tell me how to export the HH data for the overall solar generation curve? This is being requested by an ESS developer. Thanks

Hi, Solis inverter 110k 5G pro has 10mppt and 20 input on the datasheet but on PV sol database for same it shows 8 mppt and 16 inputs , could you please check this ?
