A Solar Roof, also known as a Photovoltaic Roofing System, can unleash the power of the sun and turn your roofing liability into an energy- producing asset. A building-integrated photovoltaic (BIPV) system will reduce your energy costs and your reliance on the utility grid while providing you with a lightweight, high performance roofing system.

The result is a photovoltaic roofing system that protects the building interior from the elements while generating power for its electricity needs. Not only can you save money on energy costs but often you can also get credit for feeding its excess solar power into the local electrical grid.

• Coordinated roofing/solar activities result in higher overall quality and accelerated project completion

• Roof and PV system warranties issued from the same contractor simplify any maintenance or warranty issues with a single point of contact

• Third-party financing options including Power Purchase Agreements (PPAs) address customers’ cash flow and return-on-investment requirements

• Rebate application support minimizes project’s administrative burden on customers

• Nations Roof's team of professionals have over thirty years of construction experience behind every installation which delivers peace of mind

• Nations Roof will team with approved Solar Integrators (if requested by customer)

PHOTOVOLTAIC ROOF APPLICATIONS

Roof-Integrated Systems

Nations Roof offers advanced expertise in the installation of functionally-optimized roof-integrated photovoltaic systems within commercial settings.

Advantages include:

• Coordinated roofing/solar activities result in high overall quality and
accelerated project completion

• No Roof Penetrations

• No Mechanical Fastening to Building

• Decreased Installation Costs

• Minimal Shadow

• Decreased Total Installed Weight (lbs/sq ft)

Rack-Mounted Systems

Nations Roof also develops roof- mounted solar projects using established rack and module technologies when this approach best suits our customers’ project objectives.

• Higher kWh production/watt
• Broad supply base
• Requires mounting structures
• Results in roof penetrations

The efficiency of solar cells can vary widely, from 6% for amorphous silicon-based solar cells, to 42.8% for non-commercial, multiple-junction research lab cells. The most common commercially available type of solar cell is the "Multicrystalline Si" which offers between 14-19% efficiency. While thin-film solar panels are catching up in efficiency, currently, they offer between 7-9% efficiency.

Unlike their "thick-film" cousins, thin-film panels use much less raw material in manufacturing. Additionally thin-film cells can be manufactured in a large-area process. This process can be both continuous and automated. Another unique characteristic of thin-film panels is their ability to be deposited on flexible substrate materials. This means thin-film solar panels can be integrated into roofing tiles and other architectural products. Thin-film panels are also much lighter than traditional photovoltaics.
