Photovoltaic panel electrical construction specifications and requirements

What are the NFPA requirements for solar PV systems?

The electrical portion of solar PV systems shall be installed in accordance with NFPA 70. CS512.2 (IFC 1204.2) Access and pathways. Roof access, pathways, and spacing requirements shall be provided in accordance with Sections CS512.2.1 (IFC 1204.2.1) through CS512.3.3 (IFC 1204.3.3).

What conditions should a roof support a photovoltaic panel system?

Roof structures that support photovoltaic panel systems shall be designed to resist each of the following conditions: 1. Applicable uniform and concentrated roof loads with the photovoltaic panel system dead loads.

What are the requirements for ground-mounted photovoltaic panels?

Ground-mounted photovoltaic panel systems shall comply with Section CS512.1 (IFC 1204.1) and this section. Setback requirements shall not apply to groundmounted, free-standing photovoltaic arrays. A clear, brushfree area of 10 feet (3048 mm) shall be required for groundmounted photovoltaic arrays. CS512.5 (IFC 1204.5) Buildings with rapid shutdown.

What size photovoltaic system do I Need?

1. First photovoltaic system shall be a (ground mount, roof mount) sized at xx kWAC (approximate xx kWDC) grid-tied for main facility usage. One ground mount grid-tied photovoltaic system providing approximate xx kWAC (approximate xx kWh/year for an average year using typical weather data.

What is a photovoltaic system?

photovoltaic system (or PV system) is a system which uses one or more solar panels to convert sunlight into electricity. It consists of multiple components, includ-ing the photovoltaic modules, mechanical and electrical connections and mountings and means of regulating and/or modifying the electrical output.

Do I need to meter a photovoltaic system?

It is assumed that aluminum framed photovoltaic (PV) panels mounted on a “post” and rail mounting system, the most common in the industry today, will be installed by the homeowner. While metering the system is encouraged, the specification does not address system wiring elements for associated system sensors or monitoring equipment.
