If you’ve ever driven on a freeway at night when there is road construction taking place, you’ve likely seen the huge light towers that help illuminate the road for workers. What you might not have noticed is that those lights typically run on loud, carbon-dioxide-spewing diesel-fuel-powered generators. Couldn’t there be a better way?
The Progress Solar/Wind hybrid light tower will debut at the American Rental Show in New Orleans next month. The light tower uses the combined power of a wind generator and solar generators to eliminate the need for fossil fuels. Two on-board solar power generators are used during the day, while the wind generator can be used on cloudy days and throughout the night. Progress says the generators provide enough juice to power the tower’s four overhead LED flood lights. A large battery bank can stored the accumulated power for a number of days, which can then be used as backup. In addition, the design includes a onboard AC power charger if needed.
“We are excited to be able to diversify the renewable energy resources available to insure that our light tower customers have ample energy to provide reliable bright white LED lighting each and every time it is needed,” Dan Robertson, a partner for Progress Solar Solutions, said in a statement.
The light tower is fully adjustable and can reach anywhere from 12 to 30 feet in height, while the lights can rotate and tilt in all directions. The system is housed on a portable trailer which means it can be easily taken to nearly any destination. Because it doesn’t need to the power of an electricity grid, the tower is ideal for emergency or disaster situations where power has been knocked out.
In addition to construction-site uses, by showcasing the new design at the American Rental Show, the company is also hoping to position the lighting tower as an option for people who will be renting portable lighting for outdoor events. The use of solar power means there is no emissions, vibrations or noise. The LED lights are said to last five times longer between bulb changes than metal halide lights. And, solar power isn’t subject to cost fluctuations like diesel gas, which could translate to additional cost savings.
