    Which of the use in simulation options should I choose?

    1-no shadings
    2-linear shadings
    3-
    4-
    ??

     

    Dear Furkan,

    "No shadings" is the default option when you haven't designed any 3D scene yet. Once designing your PV scene, you will have to choose between "Linear shading", "According to module strings" or "Detailed electrical calculations".

    You can find details about these modes in the following links:

    If I run the simulation after making a settlement according to the topology of my land in the close shadings tab for my project, will the production estimation result be based on these shading factors, that is, will it give results by evaluating the topology factors?

    Dear Furkan,

    Yes the simulation takes into account the shading factors based on your 3D scene

    Module's price in the Economic evaluation

    in Problems / Bugs

    Posted

    Dear Kien,

    The "by Wp" option is related to the total installed power of your system, not the price of individual PV modules.

    For a system of 500kWp, 0.5$/Wp will be equal to a total system price of 250 000 USD (500 * 1000 * 0.5).

    If you should give us details about your system (total installed power, number of modules etc...) we would be able to give you the exact calculation.

    You can send details of your project (for example screenshot of Economic Evaluation tool) to support@pvsyst.com

    Regards.

    Do I make a correct assessment by transferring the topography of the land to pvsyst with csv and then positioning and simulating it in pvsyt?
    Or are there any other steps I need to take to make an accurate production estimate?

    Dear Furkan,

    This is a correct way to perform the simulation.

    Regarding the missing option "Transform to ground object", you need to update to last version of PVsyst, this is a recent option.

    Regards.

    New tool Shading scene (ground objects)

    in Shadings and tracking

    Posted

    Dear Barbadori,

    Ground objects are objects representing the topography of your location, meaning the terrain on which you will put your panels and other shading objects. Trees are not ground objects and should not be selected in this section. 

    Moreover, in order to speed up shadings calculations, it’s very important to simplify your 3D scene by removing unnecessary and complex objects. For example, do not include in your 3D scene a tree which will not shade any panel or a complex building with useless details such as windows, doors etc... Simplifying and removing useless trees should improve your simulation performance.

    Regards.

    This will adjust the elevation of the trackers, but not the tilt. To adjust the tracker tilt to the terrain, you will need to create a zone of trackers within PVsyst, and draw the zone over the terrain. When they are generated, they will have their tilt adjusted (as long as you select the option). 

    The other option is to use autocad or some other software to place the trackers on terrain with tilt adjusted. 

    Dear Daniel,

    With the "Auto-altitude" tool the tilt is readjusted according to the base slope of the terrain. You can check this behaviour by opening the "List and management of objects" after using the "Auto-altitude". The tilt and azimuth are updated according to the base slope:

    Dear Muhammad,

    Tables need to be placed after importing the topography in order to follow the terrain.

    However, you can still reajust the position of your tables on the ground afterwards by using "Auto-altitude option" : 

    - Select all your tables and right-click on them. Then choose "Automatic altitude" option in the contextual menu:

    - Click on "Set auto. altitude":

    - Your tables will be placed on the ground:

    How to import a ground topography from GoogleEarth?

    • Open Google Earth Pro (this software is free even if it’s called “Pro”)
    • From the menu Tools>Options>Navigation, check Do not automatically tilt while zooming (in order to be always in a perpendicular top view from the ground)
    • Select a location by setting an address or by scrolling with the mouse
    • Click on the Path tool and draw as many points as possible with the mouse to define the desired area (the polygon tool will only generate the elevation data for the polygon’s corners, it’s not sufficient to extract the topography of the polygon area)
    • On Altitude tab, select Clamped to ground

    image.png.4ebc1bf23936f0d94c5bb7eeaf72eec7.png

    • Click on OK to close the path tool
    • Select the generated path and save it as a KML file :

    Im importing  the google ground image in Pvsyst and then resizing  it as described in website  and its all going okay. I want to place module on it for right shading effect .How to provide the height in google image option 

    Dear Ree,

    You can use the zone tool to fill the area with modules: https://www.pvsyst.com/help/zones_of_tables.htm

    In the zone tool, you have the option to set the height of the modules from the ground.

    CSV for tariff

    in Suggestions

    Posted

    Dear JaHu,

    We thank you for providing us details of your pricing. 

    Currently in PVsyst you can define 2 different daily tariff (Peak / Off Peak), which can be combined with 2 seasonal tariff (summer/winter).

    It's not possible to define a third daily pricing, nor a weekday depending price (price different for Saturday and Sunday in your example).

    The only way is to use a custom CSV file with all the hours of the year and the corresponding price for this hour. 

    However, in your example you have a size dependent charge (maximum demand and network access charge), which is currently not managed by PVsyst in the economic evaluation. You will be able to only define the fix pricing corresponding to each hour (2.290, 1.850, 1.410). For the monthly charge dependent part, a solution would be to create a fixed yearly operating cost corresponding to the total manually precalculated charge for your installation size).  

    Regards.

    Hizir

    Dear Debbie,

    This is indeed a known issue of the last version. We have already corrected it and the fix will be available in the upcoming version.
