|---|---|---|---|---|---|---|---|
| Version 2025 | 15/05/2025 - 12:29 | 0.0501.1a | Pre-work verification | Confirm that roof or ground area is suitable to accommodate installation of the indicated size PV system Comply with all federal requirements regarding National Environment Act, Historic Preservation Act and local requirements Verify current electrical panel and service line infrastructure is in good condition, compliant with codes, and of sufficient electrical capacity (Amps) to accommodate interconnection of solar power. Verify the position of spare (unused) breaker or space to install new breaker in panel for solar power interconnection. Any upgrades to the electrical panel or service, such as size and type of circuit breakers, shall be completed before PV system is energized If a roof installation is planned, verify that the roof will support the installation (e.g., dead load, wind load) and that the current roof covering is less than 5 years old. Verify that the type of roof is suitable for solar installation (e.g. not slate or wood shingle). The roof understructure shall be inspected and evaluated for support of PV system. Any reinforcements, such as blocking between rafters, shall be completed before load of PV system is applied If a roof installation is planned, the roof shall be inspected, cleaned and any necessary repairs shall be made If a ground installation is planned, confirm access for installing equipment, suitable slope, suitable stormwater run-off accommodation, and site soil conditions and indicate if any sub-surface infrastructure is present (underground pipes, etc) For roof-mounted or ground-mounted systems, all energized components shall not be accessible to the public through the use of locking hardware, closed wiring raceways or conduit. |

The committee agrees that aligning all solar specifications is necessary to ensure consistency across installation types. This was done to streamline efforts, and reduce redundancy across both roof-mount and ground-mount solar installations resulting in one set of specifications that align with current standards. | Red Line |
