White Roofs: Bifaciality, Maximum Use of Reflective Light.
Prism’s bifacial modules are perfectly suited for commercial roofs with white or reflective “cool roof” technologies. A cool roof has a white or special coating that reflects more sunlight, allowing the roof to stay cooler and transmitting less heat to the building.
Cool roofs reflect sunlight that can be used by the Prism module in a way that can’t be utilized by traditional photovoltaic systems. Prism modules are uniquely designed to harvest sunlight reflected off a cool white roof. The holographic film in the modules accepts angular and reflected light to increase power production in combination with bifacial, high efficiency, silicon cells.
With the use of a reflective background like a cool roof, the Prism holographic modules can increase the energy produced in kilowatt hours by up to 30% over a conventional solar module with an equivalent nameplate Wattage rating.
Financing for commercial white roof systems may be aided by the 30% U.S. Investment Tax Credit and accelerated depreciation rules which may be applied to the solar system and to the roof (consult your tax advisor), as well as cool roof rebates that are offered in many locations.
