Why does it change, and how can I ensure that PR and production remain consistent when running a one-year simulation and when using the Aging tool for 25 years simulation?

How to control the PV loss due to temperature.

What does IAM Losses mean, and what factors does it depend on? and what's the meaning of ASHRAE Model

Way when using Aging tool the the PR value was changed.

Thank you for your assistance. However, I wasn't able to locate any option in the site file to adjust the altitude. Could you kindly provide further explanation or share a screenshot to guide me? Best regards,

How can I adjust the altitude after importing site data as a custom file? The expected altitude is 757, but after import, it shows 774.

How can I perform a simulation for bifacial modules with multiple orientations and shading calculations from a shading scene without changing the field type to "unlimited sheds" in the orientation tab?

Dear Mohammad, Following your suggestion, the distribution appears as shown in the attached image. Is this acceptable for the simulation? I will certainly raise the modules further above the plant, but would this setup impact the results? The results will serve as the guaranteed values for the project. Regards, Abeer Sabbah

Dear Mohammad, Thank you for your help. As shown in the attached photo, I have a large plant with varying slopes. I initially set the tilt to 25 and then activated Auto Altitude. As a result, the actual tilt adjusted to 25.6, and the real azimuth also changed. I need the azimuth to be zero and the tilt to remain at 25, but in the current orientation, both the actual tilt and azimuth are displayed. Best regards, Abeer

Is the Snap to Grid feature enabled in the shading scene of PVsyst?

When I insert a PV array on a plant with a 3-degree slope and set the tilt angle to 25 degrees, after updating the orientation with the shading scene, the tilt changes to 25.6 degrees. However, when I check the array, the tilt is still 25 degrees. Why is there a discrepancy?

If I use Auto Distribution for the PV tables on the plant, will the azimuth of the PV panels adjust to match the plant's azimuth, or will only the slope of the array align with the plant's orientation?

How can I import an Excel file containing one year of hourly meteorological data into PVsyst?

How can I distribute PV modules for a 4 MW large-scale project on a curved ground?

How can I adjust or control the Inverter Loss over nominal inv. power ?
