It is estimated that lighting alone accounts for 12% of the total U.S. electrical consumption every year, using upwards of 461 billion kWh of electricity. This is a heavy cost to businesses, cities and municipalities. Solar lighting can provide both a financial relief as well as a green alternative to traditional lighting. They are self-contained and grid free, and with LED technology, requiring almost no maintenance throughout their lifespan. These lower installation costs compared with utility powered lighting and continue huge savings in the short and long run for most installations.
