Hi Bruno, You wrote: "It could happen that the DC is connected at a time when there is already a significant irradiance, but the ambient temperature is still low." But when the system is operating even at low temperatures, is there really a point in calculating the Voc voltage? In my opinion, at that stage the system is already in operating mode, so the voltage should be calculated based on Vmp, not under open-circuit conditions. That is, Voc can only be critical during system startup, and if the irradiance level is low, the system will transition into operating mode and everything will work properly. Am I right in thinking that considering only the worst-case scenario is not always the best approach, and that it's important to find a compromise?

Hello, I want to model a solar system with vertical bifacial solar panels. When I calculate my system using the Unlimited Sheds method, I get values that are much lower than when I model this system with Near Shadings. Which of the options can I choose for the final calculation, and which one is more accurate? Thank you for your answer.
