Dear Johnny, First of all, in a self-consumption + storage system, the system responds to the user's load. So, if you have a small load profile and a large PV system, excess energy will be injected into the grid. Since I don’t know your exact goal, I suggest creating multiple variants — starting with fewer PV modules, then trying with higher storage capacity. This will give you different results and help you find the best configuration. Regards,

Thank you, Muhammed Sarikaya.

Hello everyone. I'd have hard times using this software since I am new. I am designing a hybrid system with battery. I'd like to ask if how to properly design my system since I have only a daily demand of 313kWh and my PV system panel that is to be yield is 333kW per day. However, as I simulate my system for a year it has a lot of energy excess that is to be sent on the grid which is not ideal since my goal is that the PV should utilize the energy and the minimal excess must be on battery or to sale on grid.

Hello, Indeed, the first input of the Global horizontal irradiation is different between the two diagrams. Verify that you have the same coordinates and are using the same weather data provider.

To modifiy this parameter, you must go to the file in question then : "Additional Data" then "Secondary parameters" :

Hi all, I been learning to use Pvsyst, i recently try to compare my simulation with my friend. In the loss diagram i found that the Irradiation level for both are different. Any other setting or configuration i might need to look at given the location set point is the same.

Hi! The variable in the hourly energy variables are sometimes displayed with units "kW" instead of "kWh". This is indeed a bit confusing but for time step of one hour this is equivalent. The case of the apparent and reactive energy units should be unified with the rest in the future. In particular the reactive energy should be displayed by convention in kVARh instead of kVAh (even though they are all pseudo-units, equivalent to kW in the end).

Any response here ?

is the solution to "ungroup" the array and then set altitude per individual row?

Hi all. i have imported topo data and generated this shade scene of trackers. when i click "set auto altitude" at the highest point, the trackers do not properly follow the slope/topography. how can i fix this? less important question - the area with the highlighted streaks is always white space and i can only see the shade scene on the bottom left of my screen. why is that??

Hi, I have a display problem in 3D scene, I can only draw in a small area when I put the window in full screen. It's a bug or I have to configure it? Thanks in advance, Florent

I sent to you the file .zip with the project. Thank you

Dear Stewart, In the Near Shading tool, you need to draw your 3D scene manually — it is not generated automatically. I suggest watching our tutorial related to near shadings: Regards

Dear User, You can use PVsyst menu <File> <Export projects> to easily export your project files in a ZIP file and email it to our support address: support@pvsyst.com In the meantime, you can already read our FAQ about the most efficient way to optimize PVsyst simulation time: https://forum.pvsyst.com/topic/3542-how-to-optimize-simulation-time/?do=findComment&comment=9867 Best regards.

This is the last status before that I quite the simulation!

Hi Moderator, can you help me with the same problem? My simulation onVersione 8.0.8 is extremely slow. Can I send you the project? This is a big project but 2 hours for shadows and 4 hour for 15% of simulation are too much, so I stoped the simulation. Plese help me with a rewiev of the project. P.S. Where Can I share the project. Best regards and Thank you

Hello, I imported a SOLITEK module into the PVSYST database using the manufacturer's PAN file. After importing, PVSYST displays an error message: "Invalid PV module." "The specified temperature coefficient must be between -0.42%/°C and -0.15%/°C of VOC." How can I correct this temperature coefficient? Sincerely, Thomas Meurville

Hi, how I can plot my project after designing it in the system window and I want a 3d view of the plant align in what I design in the System window

Dear, See my example below on how to proceed: Click Orientation Management: Then, select the orientation you want to delete and delete it, as shown below: Regards,

Dear Andrés, You can use the "Zone Tool" — see below how to access it: Then, you can draw a zone where you place PV tables that follow the topography. Regards,

The inquiry above is related to the inquiry here, which is the slope (tilt) of the table does not follow terrain, only the elevation.

PVsyst should calculate this automatically.

Hello , Thanks for your reply . but i didn't insert different orientation . in the initial page of orientation i have chosen tracker N-S ( see image 1) . then i inserted the file imported from PVcase ( .PVC) in the near shading but i found automatically there are two different orientations ans therefore , i am not able to complete the simulations . in the PVcase file we checked all stings all of them have the same orientations . the problem is not existing in PVsyst 7.4

Hi, It seems like you have defined an orientation (Orientatation #2) that has not been defined in the system. In the system window, make sure that all the orientations (shown in the drop down list) has been assigned in a sub-array (list of subarrays to the left)

Hello, It's difficult to understand clearly the situation with these screenshot. Please send your project to support@pvsyst.com so we can better assist you
