Rooftop system with integrated photovoltaic modules and method for constructing the same

Abstract

This invention provides a novel design of a rooftop with structurally and functionally integrated photovoltaic modules that includes photovoltaic modules, which can be commercially available and which are augmented with additional framing including additional structural and functional layers. The modules are mounted on a grid like supporting structure sitting on vertical elevation structures, such as building walls or columns. The design enables cost reduction, fast installation and improved performance of rooftops with photovoltaic power.

Description

RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application Ser. No. 61 / 431,901, filed Jan. 12, 2011, entitled ROOFTOP SYSTEM WITH INTEGRATED PHOTOVOLTAIC MODULES AND METHOD FOR CONSTRUCTING THE SAME, the entire disclosure of which is herein incorporated by reference.FIELD OF THE INVENTION[0002]This invention relates to rooftop construction techniques in which photovoltaic modules are used as integral components of the roofing structure.BACKGROUND OF THE INVENTION[0003]As mankind continues to develop around the world, the demand for energy rises. Most energy used to power machines and generate electricity is derived from fossil fuels, such as coal, natural gas or oil. These supplies are limited and their combustion causes atmospheric pollution and the production of Carbon Dioxide, which is suspected to accelerate the greenhouse effect and lead to global climate change. Some alternative approaches to produce energy include the harnessing of nuclear en...

AI Technical Summary

Benefits of technology

This approach reduces the overall cost and installation time of rooftops with integrated photovoltaic power, providing a cost-effective and efficient method for harnessing solar energy while minimizing material duplication and structural load.

Problems solved by technology

These supplies are limited and their combustion causes atmospheric pollution and the production of Carbon Dioxide, which is suspected to accelerate the greenhouse effect and lead to global climate change.

Each of these alternative approaches has drawbacks.

Nuclear power requires large capital investments and safety and waste disposal are concerns.

Wind power is effective, but wind turbines require a windy site, often far away from grid connections and take up large footprints of land.

Hydropower requires the construction of large, potentially environmentally harmful dams and the displacement of large volumes of flowing water.

Geothermal power requires a source of energy that is relatively near the surface—a characteristic not common to a large portion of the Earth—and has the potential to disrupt the balance of forces that exist inside the Earth's crust.

However, PV is still more expensive than traditional energy resources in most parts of the world: while economy of scale and low cost manufacturing will contribute to further reduce cost, technological innovation is needed to achieve market competitiveness more rapidly and on an economically sound and sustainable basis.
