pvperfsolar performance modeling

Reference / Incidence-angle modifier, beam

Model option

Tabulated

A measured table entered on the Module tab

Inputs used: ASHRAE b₀, AR-coated glass, module.iam_angles_deg, iam.angles_deg

Method

A measured table of incidence angles and accepted fractions, entered on the Module tab while this method is chosen, is interpolated linearly between its points. A table without a 0° point starts from (0°, 1), angles beyond the last point give 0, and negative values are held at 0.
