What is your weather file location? This is a pretty common result to see at least in the US and Australia. The solar radiation is not perfectly symmetrical throughout the day and is usually higher in the afternoon, between noon and 5 pm. If you plot the Direct radiation from your weather file, I suspect you will see that during the time the peak occurs on the western facade, its higher, and during the time the peak occurs on the eastern facade, it is much lower.

What is your weather file location? This is a pretty common result to see at least in the US and Australia. The solar radiation is not perfectly symmetrical throughout the day and is usually higher in the afternoon, between noon and 5 pm. If you plot the Direct radiation Normal Radiation from your weather file, I suspect you will see that during the time the peak occurs on the western facade, its higher, and during the time the peak occurs on the eastern facade, it is much lower. lower.

What is your weather file location? This is a pretty common result to see at least in the US and Australia. The solar radiation on a surface is not perfectly symmetrical throughout dependent on the day direct normal, diffuse horizontal, and global horizontal radiation. In particular, direct normal radiation, which is usually higher in the amount of solar radiation received per unit area by a surface that is always held perpendicular (or normal) to the sun, is often highest between late morning and late afternoon, such as between noon and 5 pm. If you plot the Direct Normal Radiation from your weather file, I suspect you will see that during the time the peak occurs on the western facade, its higher, and during the time the peak occurs on the eastern facade, it is much lower.

When I plot results for a box model using a Sydney weather file, I get very similar results as you, with the western facade at almost double the peak of the east.

Update: since you overwrote your weather file data, then my above explanation doesn't hold true like it would for typical weather data. Though when I look at your model and plot the results, I don't get the same plot that you attached. Double check that you are outputting Surface Outside Face Incident Ground Diffuse Solar Radiation Rate per Area [W/m2]. When I plot this, the results are not identical but are very close to being mirror opposites of each other for the east and west facade.facade on Jan 1.

You also need to consider Site Ground Reflected Solar Radiationwhich has some slight variation.

When I plot this, the results are not identical but are very close to being mirror opposites of each other for the east and west facade on Jan 1.1, with a peak at 2597 W/m2 for Surface 3 and 2384 W/m2 for Surface 4.
