Brighten Up Your Garden with Solar Garden Lights Outdoor solar lights are easy to install and virtually maintenance free. Best of all, using them won't increase your electric bill. Popular home uses for outdoor solar lighting include pathway light sets, wall-mounted lamps, freestanding lamp posts, and security lights. Outdoor solar lighting systems use solar cells, which convert sunlight into electricity. The electricity is stored in batteries for use at night. Manufacturers most commonly use nickel cadmium, sealed lead acid, and lead acid batteries. The "nightly run time" listings on most outdoor solar lighting systems are based on specific sunlight conditions. Outdoor solar lights located in places that receive less sunlight than the solar cells need will operate for fewer hours per night than expected. Nightly run times may also vary depending on how clear the sky is on any given day. Operating times in the winter months may vary as much as 30%–50% unless the solar lighting system has been sized specifically for winter operation. If the solar cells are shaded by landscape features (such as trees and buildings), battery charging and performance will also be affected. Watch for bird droppings, too. Insufficient battery charging will not only affect performance, it also may reduce the life of the battery.
