Plan set
- Roof Plan
**Building Elevation Drawings for Roof Mounted Systems** * Provide an overhead elevation drawing or site plan drawing of the building showing the location of the panels on the roof with the street shown for reference and property lines. * Include North arrow. * Include the location of any utility lines. * Any solar installation must be located on the rear elevation or otherwise configured to the degree practicable to have a minimal visual impact as seen from the street. * Solar installations that are visible from the street must either be composed of building-integrated components (such as solar shingles) that are not readily evident, or be designed and mounted to match the shape, proportions, and slope of the roof.
- Attachment Detail
Modules to be evenly distributed to ensure the grouping is perfectly square/rectangle without any sawtooth edges or gaps Modules shall not be located on any frontward facing roofs, including along any secondary road frontages, if applicable. It is allowable in some instances if the modules are configured to match the roof dimensions.
- Electrical Diagram
**Electrical Plan** • Power riser diagram and panel schedules. Show location and size of electrical service, meter, disconnects, panels, transformer, etc. in accordance with NEC Article 690.5. The diagram must show the meter base separate from the panel. The meter should be shown schematically as self-contained with the service passing through meter. The PV connection cannot be made inside the utility meter base. Inverters should be equipped with integrated ARC-fault and rapid shutdown per NEC 690.5. o Add the following notes on the plans: o Add note, “A lockable disconnect shall be located within 6’ of the utility meter on an exterior wall and accessible to utility personnel at all times.” o Power riser must state “In the event of a Utility power outage the PV system will automatically disconnect from the utility.” Maximum Voltage per NEC 690.7 (A-E) and circuit sizing NEC 690.8. • Bidirectional meter will not be installed until all necessary Net etering Documentation has been submitted and approved by the Electrical Engineering Department. • List the specific UL and IEEE certifications (UL 1741 & IEEE 1547) that apply for systems interconnecting with an electric utility provider on the one-line diagram

**Site Plan for Ground Mounted Systems** **• Site Plan showing the arrangement of the panels on the ground, north arrow, property lines and dimensions and distance from property lines, street name and location, existing home location with front and rear labeled.** **The Rock Hill Zoning Ordinance has specific design standards for the installation of solar panels. Please see the sections below.** **Article 4-400 (18) Ground-Mounted Solar Installations In instances where roof-mounting of solar panels or solar thermal collectors is not practicable due to efficiency or aesthetic considerations, ground-mounting may be necessary. Due to differences in scale between residential and commercial/institutional/industrial solar systems, separate standards apply as follows:** **(a) Residential** **1\. Must be located to the rear of the principal structure and screened from view from public streets. 2. Must be as close to the ground as practicable and in no case higher than the principal structure.** **3\. The mounting framework must be neutral in color or screened from view from surrounding residential properties** **(b) Commercial/Institutional/Industrial** **1\. Every effort must be made to completely screen the devices from view from public streets. In instances where complete screening is not possible, the devices must be screened and/or located as to have a minimal visual impact as seen from public streets.** **2\. Must be as close to the ground as practicable and in no case higher than the principal structure.** **3\. The mounting framework must be neutral in color or screened from view from public streets.** ** ** **Allowable yard encroachments - Installations that are six (6) feet or less in height shall not project more than two (2) feet into a required yard, based on the required yards for accessory structures. Installations taller than six (6) feet may not encroach into required yards unless approved as a variance by the Zoning Board of Appeals.**
