Hi Martin, Many thanks for your support. fantastic!

Hi Martin, Many thanks for your answer and the link to the help site, this helps in starting to understand the calculations and PR predictions from PV*SOL. Some additional questions for better understanding: Could you explain how "Module-independent shading is not accounted in the calculation of the PR", as you use the "Global Radiation at the Module" for the PR calculation, and for determining the "Global Radiation at the Module" from "Global Radiation - horizontal" you use "Module-independent shading" as well? When we use a 3D model as input with regular rows of modules where the diffuse shading factor for the inner modules is higher due to the shading by the row in front, will also then the value of the first row be selected for all modules? if yes, are 3D models than only for shadow calculations from buildings, vergitation, cooling installations, etc. relatively nearby? Next, on the help site I found out that you are determining a heat loss rate UA. (where) is that included in the PR calculations? Thanks in advance

Hello, Could you please inform me if my assumption about how different shading is taken into account within the expected energy balance and PR calculations? Shadow from one row of solar panels on the next row(s) has its effect on the expected generated PV energy and so more shadow from panels on other panels leads to a lower expected PR? Next, Shadow from obstacles (buildings, vegetation, other (roof) installations) has its effect on the Global radiation at the solar module and so more shadow from obstacles leads to a higher PR? If my assumptions are correct, could you please explain me why the different kind of shadow has a different effect on the numbers? looking forward to some answers. Thanks in advance. Frederik
