I'm really sorry to open a new topic for this. I'm sure I'm failing to find something obvious.... but... Where on earth are the degradation parameters hiding? My project is currently applying zero deg to the output. So it predicts (in a slightly optimistic way) that the project financial revenue is identical for the next 25 years. I have searched the forum and found talk of these parameters, I've searched the web and found a page showing the menu from which they are accessed... only I don't have that menu! Please see attached screenshot - of my project interface, and the supposed interface found on the web help pages... what am I doing wrong that seemingly …

Hello, I would like to ask you for help with modelling a half hipped roof. Both the hipped part and the gable part of the roof have the same pitch. I would like to join these separate parts of the roof so that the panels can be fitted over both of these parts of the roof. Thank you in advance Ales

Hi, I'm using the 30 day free trial to evaluate the software and some projects. It always takes a while to get used to new software so it is somewhat painful! Big confusion, no UNDO option... amazing, unbelievable even. But my question... is it normal that the software never maximises my hardware? I'm using a rig I built for Fusion 360, Intel I3-10320 3.8 to 4.4ghz, 4 cores and multithreading. 32gb super fast ram. But when running simulations, whilst the CPU does use all cores, it is only using 17 to 18 % of the procesor power, only 16% of ram, 0% SSD and 4% GPU. Is this a problem with my machine or with the software? Why am I waiting so long?! It is a bit boring! …

Hi there. I have a project with 8 different rooftops. So, when I export the string (or cable plan) to DXF, I have to manually save the eight of them, correct the scale of each drawing and put everything together in another drawing. Is there any way I could select everything and export just one file?

Hi, I'm currently desgining an array for a block of 4 flats, they array needs to be split for each propety. Is there anyway of showing multiple grid connections, shy of creating a model for each flat? Thanks inadvance.

Dear All, I have recently purchased a full license and I really like the program interface and the simple design. I wander how the program determines the power flow in each direction and which equations/models used to generate the power flow direction. I will list my queries with the aid of the diagram below -How I tell the program to stop charging the battery from the grid (blue arrow to the batter) and compensate the 'grid to bat' energy such as to utilize a portion 'PV to grid' instead ? -Which factors/equations are used to determine 'Direct PV to load'? Why 227496kWh in particular? Any suggestions / software settings to increase 'Direct PV…

i have imported a 3d model from metashape to pv sol premium but the faces are not being detected. could someone please let me know where im going wrong. thanking you

Hey everyone, me again. Sorry for disturbing. I am having problems understanding how the software prioritize the flow of energy (battery charging over injection). And if it's possible to set up this parameter in advance. Using the following picture as an example I do not understand why the system injects so much energy instead of charging the batteries. SOC is at maximum around 13%. Modifying the grid injection does not seem to solve the problem. Thanks in advance!

Dears when comparing simulation results with power factor cosǾ = 1 with same simulation results with power factor cosǾ = 0.8, I noticed that the difference in energy production is not equal to 0.2 as losses, but it is some value which is very smaller than 20% expected less energy, so the question here how PVsol premium is calculation the power factor in simulation ? Can you pleas advise?

Hello, I have a plan roof with some obstacles (especially high attics which shade the panels). I will like to design a terrace above the attics (similiar with the bellow capture) and to put the pannels on it. I konw that i can simulate a nwe building with pitched or plan roof, and to put the pannels on this roofs, technical will be the same. But to present thu way to my client, will be difficult to explain to him my idea. So, my questios is if their is any possibility to put a terrace on a plan roof and to put the pannels on that terrace? Best regards, Marius https://www.pinterest.com/pin/660481101601746397/?mt=login

New feed-in tariff for France own consumption plus surplus sale The new feed-in tariff in France offers us a new wage band in own consumption plus surplus sale From 100 Kwc to 500 Kwc, the price and a compensation tier in Kwh/Kwc and up to 1100 Kwh to 0.1003 centimes then from 1100 to more 0.04 centimes I can’t create two rates on the resale of surplus example a solar power plant producing 1450 kwh/kwp will be renumbered 1100 kwh to 0.1003 then 350 kwh/kwp to 0.04 Question I can’t create the price on PV Sol can you help me.

Estou capturando imagens por DRONE e posteriormente gerando arquivos em 3D e na escala correta (metashape), salvando com pontos de face menor de 50 000. o PVsol abre os arquivos porém não tem a opção USAR COMO MODELO DE TERRENO, consequentemente não é possivel ATIVAR e inserir os modelos de placas e tudo mais. Além disso os programas estão abrindo com inclinação...

I am experiencing error in dragging and drop the solar panels to the roof when designing. I already restarted the PV*SOL and my laptop, but still, it is not working.

hello， I choose to record the characteristic curve of the module in the options, but I can only see the string I-V curve of the inverter MPP in the results. Can I see the I-V curve of each PV module?

Hi there, I am facing an issue in PVSol 2021 R5, related to the dimensions taken . The dimension of PVSol differ greatly from the dimension of Google earth, , please find attached a screenshot of both software’s dimensions, another screenshot is attached to make you sure that I put accurate scale of PVSol but the problem still exit. Can Anyone give me a solution for it with little details as i am beginar, please as an urgent bases. Thankyou

Hi all, Stuck! I’m unable to allocate PV panels to DC intermediate inverter and DC coupled inverters. I’m in the database view for inverter selection, but there is no drop down change available under ‘product type’. I can only select standard DC/AC inverters.. not DC coupled and DC intermediate coupled inverters. When out of 3D I have all of the databases, I just can’t access them in the inverter allocation screen. I’ve played around for a lot of one now - I’m sure it’s something simple but can’t find it for the life of me. Any help massively appreciated. Dan

Is it possible to use Pv-sol on more than one computer which one licens, or is it locked to one computer? (not at same time)

I cant use anything on the 3D visualization view i do not have the bar to add solar panels or trees or anything. is there anyway i can get this bar to appear?

Why my system is sending everything back to the grid? I do not have feed in terrif in my country

Hi, I am new to this software. My generated circuit diagram has a issue with the scale and the layout. Is there anyway to adjust this? I cannot find such an option. Also, is there an option to add AC combiner boxes into the circuit diagram? Thank you in advance. Cheers, CS

Hello, I have recently encountered a problem with PVsol Premium and I hope it can be answered. I set up an experimental bureau to compare the simulated power generation with the actual power generation.First, I imported the data processing of the environmental irradiator, which recorded temperature and irradiance , into PVsol Premium,Then, according to the actual scene modeling and simulation, the final result shows that the simulated power generation under strong irradiation is higher than the actual power generation.The red line is the simulated value, and the blue line is the actual power generation value.In simulation I set 4% dust loss.I want to know why the dev…

Hello, during try to open PVSOL filr .pvprj which I received from my coworker there appear error like this: Error during loading. Wrong file version (in translation). I have outdated version of program or what? Should reinstall of PVSOL help?

So, I had a client request the CO2 savings figures for systems with PV vs. the same systems with battery storage included. Of course, I had assumed that the systems with batteries included would have greater CO2 saving figures (or "CO2 emissions avoided" figures). However, the CO2 emissions avoided figure is slightly lower for the systems with battery. An example (not actual figures but there about!): * 170kWp Solar PV system with no battery: 150,000kWh/year production, 60,000kg/yr CO2 emissions avoided * 170kWp Solar PV system with battery storage: 150,000kWh/year production, X amount stored in battery, 58,000kg/yr CO2 emissions avoided How can …
