I strongly believe that solar power has the mettle to take conventional energy sources over. Though we are not able to figure out the technology that can make solar cells cheaper and more efficient without sacrificing their size till date, but surely future advancements in the design of solar panels could free us from the tangles of gasoline and other polluting sources of energy. For now all we have for you are these lights that harness the sun to illuminate your driveway, paths, steps and decks. These easy to install lights don’t require any wiring or electricity. Once the night falls they automatically turn on and brighten things for you with the energy they acquire from the sun during daytime.
