How it's calculated
- Output per panel = rated W × peak sun hours × (1 − losses) ÷ 1000.
- Peak sun hours are the hours of 1,000 W/m² equivalent sunshine, which is not the same as daylight hours. They vary a lot with season and weather.
- A panel's rating is measured in laboratory conditions; on a hot roof it produces less. This is a planning estimate, not a performance guarantee.
