District Photovoltaic Support Drawings

What should be included in a solar PV system diagram?

The diagram should have sufficient detail to clearly identify: Figure 10: 70-Amp Double Pole Breaker. Figure 11: Site/System Diagram. The diagram should include: array breaker for use by the location, size, orientation, conduit size and location and balance of system solar PV system. component locations.

Do you need a pull line for a solar PV system?

To facilitate the wiring of the solar PV system at a later date, the builder may also want to include a pull line in the conduit, particularly if the conduit run is lengthy or has multiple bends.

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.

What is the minimum array area requirement for a solar PV inverter?

Although the RERH specification does not set a minimum array area requirement, builders should minimally specify an area of 50 square feet in order to operate the smallest grid-tied solar PV inverters on the market.

How much space does a photovoltaic system need?

Photovoltaic modules installed on the ground or on a flat surface occupy an area of approximately 20 m2/kWp, avoiding shading between the rows of modules. The design of a photovoltaic system, from the public operator’s network to the photovoltaic modules, requires careful planning and compliance with local regulations.

What documents should be included in a solar roof plan?

At a minimum, these documents must include specific documentation of dead loads, live loads, wind loads, and, where applicable, snow loads for the existing roof design. These plans will provide important information for the solar designer when the homeowner decides to install a system.
