I am trying to define solar panel area coverage on the roof of a building but I do not really understand how to define the number of series strings in parallel and the number of modules in series. Do these values depend on the area of the roof being covered or the area of the solar modules/panels? How can I calculate these values? The solar panel model that I am using for this simulation is the Kyocera KC 120-1, object 43 in the SandiaPVdata data set. The dimensions of the roof for this simulation are length=27.69m, width=18.46m. Any help would be greatly appreciated! Thank you in advanced!
