The latest installation specifications for photovoltaic panels at the gate
The Renewable Energy Ready Home (RERH) specifications were developed by the U.S. Environmental Protection Agency (EPA) to assist builders in designing and constructing homes equipped with a set of fe. [pdf]FAQs about The latest installation specifications for photovoltaic panels at the gate
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.
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 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.
What are photovoltaic panels & how do they work?
They are designed for builders constructing single family homes with pitched roofs, which offer adequate access to the attic after construction. 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.

Is it okay to drill holes on the roof to install photovoltaic panels
Roof penetrations, which entail cutting holes on the surface of the roof to secure solar panel mounting systems, have the potential to jeopardise the roof's structural integrity and add sites of water ingress. If these dangers are not properly managed, they may result in leaks, moisture damage, and. . The process involves drilling holes into the roof to attach the mounting hardware, which is then used to secure the panels. While this process sounds invasive, reputable solar installation companies take great care to avoid causing damage to the roof.
