Photovoltaic power systems can be incorporated into virtually every commercial building. You can see examples of photovoltaic technology in outdoor security lighting, parking lots and bus stop structures. Architects can use photovoltaic building integration technology to design environmentally friendly, beautiful buildings that provide their own electricity. Pv Building integration provides a dual-use building material that reduces the cost of the PV system by using the building as an installation or support structure and reduces the electricity bill by generating its own electricity.
