Technology continues to improve as this case study of Lockheed Martin shows. Kudos to Lockheed Martin for doing their research and cost analysis regarding solar powered street lights for their Orlando facility.
The decision to investigate the feasibility of a solar-powered street light option was one already in-line with the company’s movement towards sustainable business practices. Lockheed had already committed itself to find ways to reduce energy usage across their facilities worldwide, and had already benefited from the successful installation of energy- efficient lighting at other facilities. As a result, Lockheed was looking to build similar momentum in Orlando.
But environmental responsibility aside, Lockheed had another ‘green’ consideration to contend with: cost. In the past, solar-powered outdoor lighting was a costly alternative for outdoor illumination.
But SESCO disagreed. Following a comparison between solar and AC- powered fixtures, representatives from both sides affirmed that the Carmanah solar LED streetlights would save significant cost. At $342,000 (including purchase price and maintenance) over a twenty year period, the EverGEN lights far outweighed conventional AC-powered streetlights with a cost of $563,000 (including new wiring and electricity costs) over twenty years.
