Outdoor photovoltaic base station parameters

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.

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 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.

How much weight does a PV system add to a roof?

A conventional PV system that includes racking materials will add approximately 6 pounds per square foot of dead load to the roof or structure, though actual weights can vary for different types of systems. Wind will add live loads; the magnitude of live loads will depend on the geographic region and the final PV system.

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.

Where should a solar array be located?

Builders should detail the location and the square footage of the proposed solar array area relative to the home on a project specific site plan (see Figure 1). There are multiple options for locating a solar array in a residential setting, including mounting the array on the roof or on the ground.
