Shading is the number 2 enemy of solar panels! Determining the optimal layout involves mapping the roof in 3-D using a CAD model and simulating shading over the course of a year. This allows us to identify the true impact of any shading and adapting the design accordingly. We go through this process for every project and present you with the results and the layout diagram  Wondering what the number 1 enemy of solar PV is? Night time!
