Acr38522693595560-9525ELTEC, in business for over 40 years, is known for programma-ble time clocks (NTC-17E). Over 10 years ago, ELTEC entered into solar powered systems support-ing the traffic industry. As appli-cations for solar power grew so has ELTEC’s product offering.

Some solar powered pedestrian crossings required supplemental lighting. One of ELTEC’s electrical engineers (PE) with experience in lighting applications worked with a major lighting manufacturer and designed a super bright 24 LED solar-powered fixture.

The Charleston Shipyard in Coos Bay, Oregon has “gone green”. For security reasons the shipyard needed a (solar pow-ered) light for the drive through/walk through gate entrances. Aaron Simons, Marine Facilities Manager/Harbor Master asked ODOT (Oregon Department of Transportation) to recommend a company. Aaron discussed the Shipyard’s requirements; ELTEC created the system and submitted a solar sizing report ensuring the system’s reliability. The area light-ing runs from dusk to dawn.Acr38522693595560-1577

The super bright 24 LED light fixture operates at the same frequency as the human eye. The result: ‘real life’, true color clarity. A car’s color appears as it truly is; license plates are more easily read. The long life, low amperage light fixture is rated for 80,000 hours.

All ELTEC solar powered systems are backed by a sizing report. Systems are never over sized (more expensive) or under sized, so systems won’t go dark. Coos Bay is located on the Oregon coast, which is challenging due to the number of cloudy, rainy days as well as its northern geographical location.

When asked what he liked best about the project, Aaron says it was “ELTEC’s service”. He was extremely impressed with ELTEC’s customer support and the reliable, maintenance free area lighting system.

Solar Powered Light Brightens City Park Pavilions (Marshall News Messenger 9/23/2011)

Let there be light Marshall High School student builds solar panels to bring night lighting to City Park

Marshall residents can now enjoy the Marshall City Park after dark thanks to a 17-year-old student who decided to give back to the community by installing solar lighting in the pavilions.

Jewel Ross-Gatson, a senior at Marshall High School, worked for the majority of the summer to get local businesses on board to help her build solar panels in three pavilions at the Marshall City Park.

The project was designed in order to gain her Girl Scout Gold Award, the highest award a girl scout can receive.

“Choosing the project was extremely challenging because it had to be something I loved to do, I had to give 110 percent, it had to involve the community, and it had to be beneficial for me and them, and it had to use science, technology, engineering and mathematics,” said Miss Ross-Gatson.

She said her idea to install solar panels at the park came from a first-hand experience when she and a friend decided to visit the park close to nightfall, and could barely see in front of them.

“The pavilions are beautiful and safe to play around during the day,” she said. “But during the late hours when they get off, it is unsafe for the kids to see.”
She said the idea of installing solar panels was generated by her interest in preserving the planet.

“I wanted to come up with a project to preserve the world for future generations so they can have it like we have. I want us to have clean air for your children and grandchildren,” she said.

She explained solar energy, which is gaining rapid popularity, is created by the sun hitting a solar panel, which creates an energy charge that can trigger either DC or AC power.

She said the solar panels are charged throughout the day, and automatically switch on to produce an LED spotlight when it gets dark.

“The sun energy output is, one hour absorbed by the sun energy rays is equivalent to a yearly energy consumption by the entire planet,” she said. “It is just that strong. One of those that is not burning up. There is a lot of energy out there.”

She said after visiting with city commissioners, police officers, and park directors, she found out the lack of lighting was leading to the recent vandalism in the park.
“They said the security cameras there but there is not enough lighting to see anything,” she said.

She said after getting city officials on board, she needed to present her idea to local businesses in order to receive funding.
“Bill Marshall, owner of ELTEC traffic and solar productions, donated solar panels to us,” she said.

She said after receiving the panels about three weeks ago, she worked with a couple of volunteers to build the solar panels, which she said was not as easy as it seemed.
“There is more to building it than meets the eye,” she said.

She said Jim Putnam, ELTEC employee, walked her through the building process, even providing a diagram.

After the battery and the charging system she and volunteers set up the poles on the south side of each pavilion.

“I placed the poles for the solar panels on the south side of each one because the sun rises in the east and sets in the west, so we wanted the solar panels to get the most sun light,” she said. “And it was a very very heavy pole, and I could not have done it on my own.”

She said the poles blend perfectly to the side of the pavilion, and are not noticeable unless one looks for it.

“The first time I saw them lit up, I was very excited. The end results, I loved it, and it was bigger than I expected,” she said. “Now families can now stay longer, activities that are held you can stay longer at the park longer so now it is being used for its full potential.”

Solar Lightning Valero (IMSA Sept-Oct ’09)

ELTEC ‘lights the way’ for Valero employees

Published in the Sept-Oct 2009 IMSA journal

A Valero Refinery in Texas has high pedestrian traffic during shift changes. Because of the size of the facility, there is constant traffic with motorized vehicles. Lack of clearly marked pedestrian crosswalks exacerbated during dark hours endangered employees.

IMSA Sept-Oct '09 Solar lighting Valero-3To improve safety, Valero undertook a multi- prong approach. First, they established multiple pedestrian crosswalks. Second, they erected 24 hour flashing beacons at each crossing. The third element was to make pedestrians more visible during the dark hours by illuminating the crosswalks.
Valero is committed to supporting ‘green’ solutions. In support of this they chose ELTEC’s solar powered system to supply the outdoor lighting in conjunction with 24 hour flashing beacons.

ELTEC designed the solar power source to ensure no loss of load under all operating conditions. The beacons flash 24 hours; the solar outdoor lights operate from dusk to dawn.
Valero has been extremely pleased with the system’s operation and safety performance. They are now considering additional solar lighting along the road to further illuminate the pedestrians as well as speed feedback signs to advise motorists of their speed.

ELTEC is currently installing solar outdoor lighting at Charleston Marina in Coos Bay, Oregon. This lighting will be used at the entrance gate.

ELTEC’s solar outdoor lighting system provides sustainable solutions at affordable prices. For further information on solar outdoor lighting and solar solutions, contact Sales@ELTECCORP.com or call 800-227-1734.

Marshall News Messenger – Celebrating the Sun 6/20/2010

Solar power continues to grow in popularity and using solar energy is a mainstay for products created at Marshall’s Electrotechnics Corporation (ELTEC), 1310 Commerce St., which manufactures a variety of traffic systems.

“We have been working with solar for 20 years. In 2000, we probably sold 100 systems compared with the 600 sold this year,” said ELTEC President Bill Marshall.

This weekend, businesses and individuals across the nation are celebrating SolarDay, which was founded in 2009 to increase awareness of the benefits of solar energy. Benefits include creating sustainable lifestyles and businesses as well as the adoption of green and clean-technology.

“The premise of SolarDay is simple: a national day of recognition for solar, energy independence and protection of the planet,” according to the SolarDay Web site.

A young holiday, SolarDay began in 2009 and is celebrated the weekend before June 21, the Summer Solstice and the longest day of the year. This year it was celebrated June 19, according to www.solarday.com.

The popularity of solar power is evident from its growth and the diversity of its uses.

ELTEC uses solar power in its traffic lights, warning beacons, school zone flashers, pedestrian crossings, industrial traffic lights and as a creative solution to virtually any other power requirement in remote places.

“Our solar business grows 10 to 20 percent over the previous year, and that’s not price appreciation affecting this,” added Marshall.

The cost for building these solar systems fell in some areas as the technology of the lower power LEDs (light emitting diodes) improved. The amount of solar and battery power needed to run the systems decreased.

“LEDs draw less power. I need less batteries and I need less solar panels,” explained Marshall. “The little LEDs are five watts, the bulbs used to be 30 watts, which used to be a lot of power consumption. Now it is down to five.”

ELTEC uses Kyocera solar panels, which come in different strengths measured in the number of watts they can generate. During the daytime, the solar panel powers the lights and also charges a battery for use at night.

Knowing how much solar power is needed for a system is as easy as running some figures through a computer program. The program was developed at ELTEC so that their solar systems could be made to handle most remote power needs.

“It’s a computer based program with the parameters. It allows us to design a system that will perform without failure,” said Marshall, who added that solar systems can use as many panels as needed to charge the batteries or to power the.

He displayed a photo of a system with eight, 135 watt panels, powering a series of traffic cameras, as an example.

“We just shipped an interesting system to the city of Philadelphia, Pa., where they had a faucet for sampling their water system and needed to power heat tape 24-hours a day in the winter time,” said Marshall.

ELTEC offers creative solutions to municipalities.

“If you tell us what the load is, we can size the system to determine the correct number of panels and the number of batteries,” said Marshall.

Marshall said the solar units are popular because their cost is all up front without the need to continually pay for powering them. Paying to extend conventional power lines is expensive and even more so when needed in remote places.

“Ease of installation is another reason people choose solar. The system is a pole with a cabinet and the area light. All you have to do is erect that right there, and you don’t have to worry about getting power run to it,” said Marshall. “There is no maintenance or utility charges.”

Solar systems are applied to “load operating beacons” which alert people to certain traffic conditions or traffic cameras, traffic counters and feedback speed limit signs.

Also included is a device, the brains, that control the charging of the battery. It is programmed to know when the sun is out, when to engage the solar panels.

“At night, it keeps it from trying to charge the battery from the solar panel,” said Marshall. “We could run these 24 hours a day if we wanted to.”

The batteries are made with a sealed gel absorbed into a fiberglass material with “no loose liquid in it” so does not spill if the battery is damaged.

Solar systems like this can run 24-hours a day and are generally sold for $3,000 each. Marshall began with the systems in the early 1990s and said there have been systems, built in Marshall, installed in cities in all of the lower 48 states, Hawaii and Canada.

“We’re increasing our distribution throughout the U.S.,” said Marshall. “We have added distributors in Utah, Alaska, Nevada and Minnesota.”

Some systems are self contained on a timer, but others can be managed from a control area for warnings.

“They use them in Wyoming when they have winter storms and they want to close the mountain passes,” said Marshall. “From a central location it can be radioed to activate the beacon saying ‘Road Closed’ and it will also close the gate. These have some conventional power and some solar power.”

One of ELTEC’s newest products is an Internet-based school zone time clock that is networked to radio signals to the flashers as to when they should be off or flashing.

“We think that is going to be really innovative technology in this industry,” said Marshall. “At a school zone, the clock turns the lights off and on. If it’s a Saturday or a holiday, it says ‘don’t come on’ or is on at the right time for an early dismissal.”

The new time clock is important for managing the power load and being able to activate the light systems for just the right amount of time each day.

They can be also found at pedestrian crossings, 24-hour warning beacons.

Another place ELTEC’s solar and light systems are useful is in industrial traffic where trucks and heavy equipment operators may have to wait in line. The signals reduce accidents and set expectations on the yard.

“At one steel mill, we went up and installed this system, and they called and said they needed another,” said Marshall.

At a waste management yard, the bulldozer operator controls a traffic light for those dumping from the bulldozer, Marshall said.

ELTEC has been “green” before green was cool

ELTEC has been “green” before green was cool. We’ve been supplying solar powered systems to the traffic industry since the mid 1990’s.

For the past few years we’ve had voluntary recycling in the common/lunch area, recycling aluminum cans, plastic bottles/containers, magazines & catalogs, glass, and grocery bags.

Recently ELTEC initiated a companywide office and production floor recycling program. In addition to the above items, all cardboard boxes, shrink wrap, bubble wrap and other miscellaneous objects are collected in separate bins located in all offices and each production area of our 20,000 square foot facility.

The recycling program has reduced ELTEC’s landfill garbage collection by approximately 85% and is saving ELTEC over $1,000 a year in garbage fees. It pays to recycle in so many ways.
