Solar-Powered Walkway and Patio Lights
Outdoor lighting powered by solar energy is an excellent use of solar technology that improves your home's appearance without adding to your electric bill. Each light fixture consists of a solar collector (a photovoltaic panel) that converts daytime solar energy into electrical energy, which is stored in a rechargeable battery. At night, the battery is used to light the fixture, typically a soft white light using the latest in LED (light emitting diode) technology. Colored lenses are also available. Each solar light operates independently and there is no need for trenching, wiring or even a transformer. You can see how this makes it easy to use in remote areas and locations near water.
Models are available to both turn on manually or turn on automatically; by either a motion sensor or a light-sensing control. All solar lights require unobstructed sunlight during the day to recharge their batteries. With fully charged batteries, most models will stay illuminated for up to 15 hours. When it is shady, cloudy, rainy, or snowy during the day, performance will be diminished. While they will not produce nearly the amount of light as will low voltage or 120 volt path lights, their output is sufficient light to mark entrances, accent walkways and steps, and to indicate the location of darkened obstacles at night.
