Photovoltaic (PV) Panels
The durability of a metal roof is impacted by both the PV panel system and roofing assembly, so both should be considered during the design and installation process, and in follow-on
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.
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.
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.
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.

Solar PV mounting systems utilized on face-fastened metal roof systems are installed using bracket components mechanically attached either through the panels to the underlying substrate or building
Install a mounting system for solar thermal or solar photovoltaic panels. Consider the roof type (material and slope), weatherproofing, installation convenience, and wind and snow loadings.
