We use a special state of the art online program to design the solar system.
A Design contains the physical layout of a solar array, including the detailed module layout, orientation, roof shape, and surrounding obstructions. It also includes the electrical design, including wires and inverters. A Project can have multiple Designs, often these multiple designs are used to compare design alternatives. The system extract weather data for the exact location of the project from an online internationally recognized weather data sources. includes ground weather data from the National Renewable Energy Laboratory (TMY2 and TMY3), Solar and Wind Energy Resource Assessment (TMY), and DOW (EPW) where available. It also includes satellite-based weather files from Prospector, Meteonorm (Meteonorm 7 and 8), and Physical Solar Mode (v3).
