4 FAQs about Aerial Photovoltaic Panel Installation Specifications

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 do I install a Rerh solar PV system?

Install a 1” metal conduit from designated inverter location to electrical service panel (cap and label both ends). Install and label a 70-amp dual pole circuit breaker in the electrical service panel for use by the PV system (label the service panel). Provide architectural drawing and riser diagram of RERH solar PV system components.

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 roof space does a solar system need?

would require on the order of 500 square feet of usable roof space (average of 1 kilowatt per 100 square feet) to install the solar panels. However, homes with a higher than average level of energy efficiency, such as those meeting ENERGY STAR® Homes Standards, may not necessitate an average-sized system.
