Hi, When simulating a particular project and reading the EB, I can see that the module independent shading, which I normally assume to be due to the horizon (far) shading is just below 6%. Looking to the module dependent shading, I can see that this is at around 16%. Two aspects are interesting when it comes to this: The total shading loss over the year, presented in the summary, is 23.2%. Removing the horizon from the 3D model reduces the module dependent shading almost entirely. Knowing how the help file defines independent and dependent shading, I am a little
In the simulation results, can someone please explain the physical meaning of the module specific partial shading and is there a way to present a graph that would show the shading losses during one day (best 21st of December) ?
Hello, I'm trying to run a basic simulation with one module tilted 30% facing south (azimuth 180 degrees), with a wall partially obstructing the view to the south. I've setup the scene, and when I run it there are outputs: Area South: Irradiance onto tilted surface [kWh/m2] Shading [kWh/m2] I'm finding that the shading losses compared to the irradiance (which I assume is the plane-of-array quantity) are much lower than I would expect. For a full year, I'm seeing: Shading - 25 kWh/m2 Area South: Irradiance onto tilted surface 1921 kWh/m2. Which is a 1.3% annual loss. Ho
Hello, I am trying to run a simulation for a system where I've set up a 3D shading scene. When I click to generate results, two simulations occur. The first is the calculation of shading losses. This appears to run for the full 365 days. The next simulation says "Simulating", but only runs until day 239 before stopping. Then, the "Hourly Values" csv file only has data until August 28. Is there a setting somewhere that would govern this behavior? Thanks
