Solar Outdoor Lighting
Tapping the limitless solar energy is a simple, economical and a profitable way to save depleting natural resources. Solar energy, a relatively new multifaceted concept in energy harnessing, provides us with low cost alternative to traditional lighting systems. The energy of the sun is stored by solar panels or generators by charging long life batteries and discharge of this electricity is stopped by sophisticated proprietary charge regulators when batteries are fully charged. This enables the solar outdoor lighting to work even on cloudy or rainy days.
Solar outdoor lightings have progressed from earlier models using incandescent bulbs burning out faster without producing enough light to the present models with LED or light-emitting diode light bulbs and nickel-cadmium or nickel-metal-hydride batteries. These use less electricity and last longer. Another reason for growing popularity of solar outdoor lighting is that it is cost efficient and maintenance free unlike traditional electricity system. The solar panel backed by warranty and personalized power plant energized by sun is not dependant on generating stations, substations, switches, transformers or transmission lines. Secondly solar outdoor lightings are self programmed and if one fails the other light is not affected. A one time installation cost as opposed to running costs towards cables, trenching, metering equipment, construction and electric bills tilts the verdict in favor of solar lights. (more…)
