What does East-West Array mean?
An east-west array is a PV layout with modules facing both east and west, spreading production across morning and afternoon hours.
Why do installers use east-west arrays?
East-west layouts can make better use of roof space and create a broader production curve. The system may generate less at solar noon than a single ideal orientation, but more during morning and evening windows that can matter for load offset and utility rates.
