Does PVSol apply a default 1% discount to total production to account for the average light-induced degradation of PV modules during the first year? I have modified the module degradation in the 3D visualization section. In the first year, the total power is 99%. However, the generation result for the first year decreases by only 0.5%. Additionally, there are no changes to the annual specific output or the CO2 savings. Why is the output reduced by only 0.5% instead of 1%, and why do the CO2 savings or kWh/kWp remain unchanged?

Hi, I have a question regarding how module degradation might affect standby consumption. I've noticed a discrepancy in the first-year generation figures: the simulation results show 792,161.3 kWh, while the report states 792,333 kWh. Please see attached screenshots. Could this difference be attributed to standby consumption being 72 kWh instead of the 86 kWh mentioned in the report? Thank you. Kind regards, Felix Galan

I have a similar case in which the annual generation in the results, does not match with the annual generation of year 1. I have set P50 in bankability, for a 25-year observation period, and the following module degradation profile: Year 1: 99% Year 31: 87% The result for year 1 within the observation period is around 0.4% lower than the estimated annual generation. PV Generator Energy: 23,848 kWh/y Energy Year 1: 23.724.5 kWh Which generation is the correct one? Is 23,848 kWh a generation for year 0? Why do I have a result for 26 years when the observation period is 25 years? Thank you

I have seen in the below link that PVSol has decided not to calculate the radiation gains of bifacial panels for inclination angles lower than 10 degrees. Will this be considered in the future? This affects one of my model for a carport with a 7-degree inclination. It is a big system (almost 1MWp) in which the gained radiation might make a difference, as I try to optimise the system to export as minimum electricity as possible. For others cases with elevation between 10 and 80 degree, how is the rear albedo calculated? Is it possible to input this value?

Hi, How can I display the characteristic curves for a grid-connected project? When I select characteristics curves in the diagram editor, I obtain the message: "No characteristic curves available. Please activate recording of characteristic curves in Program Options". I have selected: "Record characteristic curves for modules/All" in Options/Project Options/Simulations. However, I still cannot see the characteristic curves. Is there anything else I must do to obtain the characteristic curves? Thank you.
