Agustín Doña Posted September 15, 2022 Share Posted September 15, 2022 Hello everyone, I was running some cases in PVSyst 7.2.17 with bifacial panels. I simulated one HSAT (backtracking enabled) and one fixed tilt (16° tilt, 90° azimuth, South hemisphere) configuration, all else being equal. For the fixed tilt configuration I used a Near shadings 3D scene together with "According to module strings" for shading loss calculation. When retrieving hourly results, I obtain greater GlobEff for the fixed-tilt configuration even close to midday and with no relevant diffuse component. I attach an image with some of these cases (I found ~60 hours with this behavior throughout the year). Even if the differences are low in absolute value (decimal differences) this caught my attention, given that at those hours the tracking system should be receiving more irradiance than the fixed tilt configuration. Maybe there is some modeling configuration I am not looking at. Thank you very much in advance for your answers ! Link to comment Share on other sites More sharing options...
