Whether a pointed gable, tented roof, modern city villa, single-family home or apartment building, it also pays to install PV modules on the north-facing side of buildings. This delivers more energy yields and makes system operators independent of rising electricity prices. With the Sunny Design planning software, you can display up to six module arrays during system planning, allowing you to incorporate more roof surfaces into the design from the outset. We will show you how to do this (including with a carport) for north-facing installations as well, because diffuse light can also result in a good yield. The software allows you to easily design complex systems in a single step.
