I'm reaching out to get a better understanding of the expected energy output from your solar system solutions. Considering the dimensions of my roof and my specific energy consumption needs, I want to know how optimally the system can perform in my scenario. Could you provide insights into the energy yield I might anticipate from the installation? Additionally, any details on how the system's efficiency may change based on roof orientation or shading factors would be super helpful. Thanks!
