Latest photovoltaic panel system configuration specifications

What are the requirements to install a PV array?

The mounting frame/support for the PV arrays is to be weatherproof and corrosion resistant. The lifetime of the mounting structure must exceed the lifetime of the PV arrays. The contractor is responsible to ensure adequate and safe connection of the roof framing to the building/roof structure.

What are the requirements for a solar array mounting system?

The solar array mounting system and connection must be provided with a minimum manufacturing warranty of 10 years. The system must comply with AS/NZS 5033 and Clean Energy Council Installation guidelines.

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.

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.

Can a roof be integrated with a PV system?

Building integrated PV (BIPV) modules, which can be integrated into the roof itself, might be considered for new construction or for an older roof in need of replacing. While BIPV products currently have a premium price, costs are expected to decrease. Will it be connected to the utility’s transmission grid?

How many kilowatts can a PV module generate a year?

Each 1,000 watts of PV modules can generate about 1,000 kilowatt-hours (kWh) per year in locations west of the Cascades and about 1,250 kWh per year east of the Cascades. When using less efficient modules, such as amorphous silicon or other thin-film types, the area will need to be approximately doubled.
