# Solar-panel orientation screening
# Scope: Direct-beam incidence cosine only; diffuse irradiance and shading omitted.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

irradiance = 800 W/m^2
incidence = 30 deg
area = 2 m^2
efficiency = 0.2

power := irradiance*max(0,cos(incidence))*area*efficiency [W]

check power target: power >= 200 W

scenario alternative: irradiance = 640 W/m^2
