Solar electric systems can be connected throughout a utility grid to provide an additional power source for homes and businesses. Grid connected applications continue to experience rapid growth due to the increased incentive programs, reliability and cost savings associated with a portfolio or power solutions. In 2006 alone, the worldwide on grid market segment grew by a remarkable 22% to 1,537MW (MarketBuzz 2007).
Home and business owners that use grid connected solar power benefit from lower monthly utility bills through net metering and can take pride in the fact that their systems generate no harmful pollutants.
Net Metering - How it works:
When a home or business requires more electricity than the solar system is producing (at night or cloudy days), utility power is brought in to supply the demand. In contrast, when the solar system produces more electricity than it requires, the excess can be sold back to the utility through a process called net metering. Therefore it is possible for a home or business using a grid connected solar system to actually sell more electricity back to the utility than it uses.
Building Integrated Solutions
Building Integrated Photovoltaics (BIPV) is often referred to as the next revolution in solar power generation.
BIPV systems not only produce electrical power from the sun, but also form an integral part of the building structure. Recent examples of BIPV can be seen on roof shingles, awnings, walls, facades, skylights and window shutters. The main advantage of integrating solar into building materials is that the overall cost of the system can be reduced significantly; one product performing two very important functions.
Another advantage of this innovative concept is aesthetic appeal. Many resident and business owners are not pleased with the overall look of traditional glass solar modules fastened to their open roof space. BIPV can blend into the building structure, thus maintaining the visual and architectural request.
In recent years the building materials industry has made a push to a more sustainable approach. With programs such as Energy Star gaining momentum in North America, the demand for building material efficiency will lead to innovative building material products.
