They<br />work any time the sun is shining,<br />but more electricity is produced<br />when the sunlight is more intense<br />and strikes the PV modules directly<br />(as when rays of sunlight are perpendicular<br />to the PV modules). Unlike<br />solar thermal systems for heating<br />water, PV does not use the sun's<br />heat to make electricity. Instead,<br />electrons freed by the interaction<br />of sunlight with semiconductor<br />materials in PV cells are captured<br />in an electric current.<br />PV allows you to produce electricity—<br />without noise or air pollution—from<br />a clean, renewable resource. A PV<br />system never runs out of fuel, and it<br />won't increase U.S. oil imports. Many<br />PV system components are manufactured<br />right here in the United States.<br />These characteristics could make PV<br />technology the U.S. energy source<br />of choice for the 21st century.<br />The basic building block of PV technology<br />is the solar “cell.” Multiple<br />PV cells are connected to form a PV<br />“module,” the smallest PV component<br />sold commercially. Modules<br />range in power output from about<br />10 watts to 300 watts. A PV system<br />connected or “tied” to the utility<br />grid has these components:<br />• One or more PV modules, which<br />are connected to an inverter<br />• The inverter, which converts the<br />system's direct-current (DC) electricity<br />to alternating current (AC)<br />• Batteries (optional) to provide<br />energy storage or backup power<br />in case of a power interruption<br />or outage on the grid.<br />AC electricity is compatible with<br />the utility grid. It powers our lights,<br />appliances, computers, and televisions.
