# Solar-array sizing
# Scope: Daily energy and equivalent peak-sun hours; no hourly weather model.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

dailyEnergy = 1000 Wh
sunHours = 4 h
derating = 0.8
panelRating = 200 W

requiredPower := dailyEnergy/(sunHours*derating) [W]
panels := ceil(requiredPower/panelRating)

check panel count budget: panels <= 3

scenario alternative: dailyEnergy = 800 Wh
