§ 110.10(a)2: requirements of § 110.10(b) through § 110.10(d).
Minimum Solar Zone Area. The solar zone must have a minimum total area as described below. The solar zone must comply with access,
pathway, smoke ventilation, and spacing requirements as specified in Title 24, Part 9 or other parts of Title 24 or in any requirements adopted by
a local jurisdiction. The solar zone total area must be comprised of areas that have no dimension less than 5 feet and are no less than 80
square feet each for buildings with roof areas less than or equal to 10,000 square feet or no less than 160 square feet each for buildings with
§ 110.10(b)1: roof areas greater than 10,000 square feet. For single family residences, the solar zone must be located on the roof or overhang of the building
and have a total area no less than 250 square feet. For low-rise multi -family buildings the solar zone must be located on the roof or overhang of
the building, or on the roof or overhang of another structure located within 250 feet of the building, or on covered parking installed with the
building project, and have a total area no less than 15 percent of the total roof area of the building excluding any skylight area. The solar zone
requirement is applicable to the entire building, including mixed occupancy.*
§ 110.10(b)2: Azimuth. All sections of the solar zone located on steep -sloped roofs must be oriented between 90 degrees and 300 degrees of true north.
Shading. The solar zone must not contain any obstructions, including but not limited to: vents, chimneys, architectural features, and roof
§ 110.10(b)3A: mounted equipment.*
Shading. Any obstruction located on the roof or any other part of the building that projects above a solar zone must be located at least twice the
§ 110.10(b)3B: distance, measured in the horizontal plane, of the height difference between the highest point of the obstruction and the horizontal projection of
the nearest point of the solar zone, measured in the vertical plane.*
Structural Design Loads on Construction Documents. For areas of the roof designated as a solar zone, the structural design Toads for roof
§ 110.10(b)4: dead Toad and roof live load must be clearly indicated on the construction documents.
Interconnection Pathways. The construction documents must indicate: a location reserved for inverters and metering equipment and a
§ 110.10(c): pathway reserved for routing of conduit from the solar zone to the point of interconnection with the electrical service; and for single family
residences and central water -heating systems, a pathway reserved for routing plumbing from the solar zone to the water -heating system.
Documentation. A copy of the construction documents or a comparable document indicating the information from § 110.10(b) through
§ 110.10(d): § 110.10(c) must be provided to the occupant.
§ 110.10(e)1: Main Electrical Service Panel. The main electrical service panel must have a minimum busbar rating of 200 amps.
Main Electrical Service Panel. The main electrical service panel must have a reserved space to allow for the installation of a double pole circuit
§ 110.10(e)2: breaker for a future solar electric installation. The reserved space must be permanently marked as "For Future Solar Electric".
