TL;DR
Solar access is the fraction of available sunlight a specific roof plane or ground location actually receives over a year once shading from trees, buildings, and terrain is subtracted, expressed as a percentage. Installers measure it during the site survey, and values above roughly 90 percent mark a strong production site, while heavily shaded planes get excluded from the design.
What it means
Solar access is the fraction of available sunlight a specific roof plane or ground location actually receives over a year once shading from trees, buildings, and terrain is subtracted, expressed as a percentage. Installers measure it during the site survey, and values above roughly 90 percent mark a strong production site, while heavily shaded planes get excluded from the design. Some states also use the phrase legally, protecting an owner's sunlight through solar access laws and easements that limit what neighbors may shade.
