  1. Huge Discrepancies between Power output in horizontal tracking bifacial system.

  2. Huge Discrepancies between Power output in horizontal tracking bifacial system.

    Daisy posted a topic in PV*SOL
    Hello Support, I designed a fixed vertical agriPV system on both PVsyst and PVSOL Premium and got quite similar power outputs. I designed a horizontal N-S tracking bifacial agriPV on PVsyst and PVSOL (using the same modules and system input details as the fixed vertical one) but the difference in the power output was 70 MWhrs/year. In the design, the pitch was 10m, the elevation was 3.5m, the tracking was +/- 55 degrees. I understand that both software are different but I ensured that the time step, input data and losses from both were close to similar. How come the results differ so much? Is it due to the 2D design of tracking systems, or the use of both bifacial and tracking systems?
