BIPV: Built-in photovoltaics can take the place of conventional glass and roofing

A promising new "green" energy technology that breaks down pre-existing concerns and hesitations about solar energy is called Building Integrated Photovoltaics (BIPV). BIPV systems actually build solar cells into the construction materials of a building. They end up looking as natural as what would have been a conventional roof, window, awning, and even concrete.

BIPV systems can provide savings in electricity and sometimes home heating costs for many years. In some areas where there is a lot of sunlight, solar energy can completely replace conventional electric sources, but in almost every area the electricity provided will provide enough benefit to make conversion to photovoltaic (solar) worthwhile

BIPV systems can be made to be “on-grid”, or hooked into the local electric company. That way, not only does the homeowner get “free” electricity for their own home, they also can automatically sell any extra back to the utility. Not only might you receive no electric bill, you might actually receive a check back instead each month! On the grid systems also guarantee a back-up source of power if necessary.

BIPV systems can be designed to blend in and look exactly like conventional building materials and designs, such as external structures including awnings or skylights. However, the most common use of building integrated photovoltaics is BIPV roofing, where solar shingles are substituted for traditional roofing.

As exciting as the above technologies are, there has even been research lately about building photovoltaic solar cells into the walls of buildings - into concrete and other basic building materials. Soon BIPV technology may be widespread and conventional, but for now building integrated photovoltaic solar can get you a head start while saving electricity and reducing your carbon footprint. You will also serve as a positive model for others.
