This 3.7 KW grid tied PV system has helped the owners achieve their goal of a zero energy home - a home that uses no more energy than it can produce onsite. The Sunny Boy 3800 Watt battery-less inverter sends power back into the electrical grid during the day when household electrical use falls below electrical production of the photovoltaic system. After installation, the owners experienced additional savings in their electrical bill from the reduced need for their air conditioner. The photovoltaic system acts as a second roof over the areas of the roof where it is installed, reducing heat gain to the building below. Townhouse associations are required by law to create a procedure for allowing the property owners to install solar hot water and photovoltaic systems.
