Solar Electric PV (Photovoltaic)
A Solar Electric, or Photovoltaic system, converts sunlight to electricity. The conversion process requires only the sun’s energy and releases no harmful pollutants, which is why solar is sometimes called free fuel or clean electricity.
Solar Electric PV Panels: The solar panels themselves come in different shapes and sizes from a host of manufacturers, allowing us to put together a customized system that perfectly suits your home or business. On the roof, a series of panels – usually 8 to 20 - are linked together to create a system whose size is measured in kilowatts (kW), with a typical solar electric residential system being 2 to 5 kilowatts in size. For an array to be efficient, panels need to be oriented so as to receive the greatest amount of direct sunlight during the peak hours of the day, typically from 9am to 3pm. An optimal installation is flush mounted on a south facing, unshaded roof, but other orientations work as well. A site evaluation is important to determine the effectiveness of any solar array.
Inverter: From the rooftop solar electric array, direct current electricity travels to an inverter, located in the basement or utility closet, near your electric panel. The inverter changes the direct current (DC) to alternating current (AC) and feeds that power to your building. Inverters come in different shapes and sizes, but they all output the alternating current electricity that we use everyday.
Net Meter: Usually on the outside of your home, you have a conventional electric meter installed by your utility company that measures how much power you consume and determines your monthly electric bill. When you install a solar electric system, the utility company replaces that meter with a new net meter, free of charge. This net meter spins both directions, measuring the electricity you produce as well as the electricity you consume from the utility, so your electric bill is based on the net difference.
PV Controller & NetMonitor: The final component of the solar electric system is the Controler NetMonitor. This small box attaches to your solar system and your internet connection. It feeds power generation data to a web-server allowing you to track your own system output.
