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.

How does East-West Array affect PV system design, production, or customer expectations?

In solar projects, this term helps teams describe equipment, design assumptions, documentation, or field workflows with less ambiguity. Precise vocabulary reduces mistakes between sales, design, installation, inspection, and support.

Practical design considerations

Use the term consistently across product pages, technical documents, and support content.
