Shading on the PV array from obstructions shall be eliminated or avoided as necessary to meet performance requirements under the performance approach or the prescriptive limit on shading under the prescriptive approach (stated in JA11.3.1). Any obstruction located north of all points on the array need not be considered as shading obstructions. Obstructions to consider include:

1. Any vent, chimney, architectural feature, mechanical equipment, or other obstruction that is on the roof or any other part of the building.
2. Any part of the neighboring terrain.
3. Any tree that is mature at the time of installation of the PV system.
4. Any tree that is planted on the building lot or neighboring lots or planned to be planted as part of landscaping for the building. (The expected shading shall be based on the mature height of the tree.)
5. Any existing neighboring building or structure.
6. Any planned neighboring building or structure that is known to the applicant or building owner.
7. Any telephone or other utility pole that is closer than 30 feet from the nearest point of the array.
