Solar access measurement

A method of determining solar radiation exposure at a predetermined location, the method comprising:

• determining a plurality of elevation/azimuth pairs, wherein each elevation/azimuth pair of the plurality of elevation/azimuth pairs represents a vector extending from the predetermined location;
• and
• generating a two-dimensional (2D) solar access matrix including a plurality of elements, wherein each index of the solar access matrix includes an elevation/azimuth pair of the plurality of elevation/azimuth pairs, wherein each element of the plurality of elements of the 2D solar access matrix represents an amount of solar radiation to impinge on the predetermined location from a direction of an associated elevation/azimuth pair.

A method of determining solar radiation exposure at a predetermined location, the method comprising generating a two-dimensional (2D) open sky matrix including a plurality of binary elements, wherein each index of the 2D open sky matrix includes an elevation/azimuth pair of a plurality of elevation/azimuth pairs, wherein each binary element of the plurality of binary elements of the 2D open sky matrix represents whether or not a light ray extending from the predetermined location in a direction of a respective elevation/azimuth pair of the plurality of elevation/azimuth pairs is obstructed by an obstruction.
