Solar Bus Stops & Bus Shelters for Energy Efficient Transit System

Posted by SEPCO

12/4/14 3:22 PM

Solar Bus ShelterBus stops and shelters are used along any bus transit system. These areas provide information to travelers along the route to make sure they get where they need to go at the times they need to get there. Daytime travelers do not have to worry about visibility; however, at night, lighting is required to ensure the bus driver spots them and they can see the information on the routes. This is where solar lighting can easily come in to play.

Most bus stops and bus shelters are located in an area that grid power is not easily accessible without tearing up the nearby area to bring wires out to the location. Solar makes the lighting at night possible since the solar is either roof or top of pole mounted. The power is generated wherever it is needed without the destruction of surrounding areas.

Solar bus stop light systems consist of a pole mounted solar power system that provides power to a fixture, sometimes integrated within the battery assembly, and can provide lighting all night, via a motion or push button activation, or on only when the transit system is in operation. These systems are completely integrated together and can be installed in just about any sunny location along a route.

Solar Bus StopSolar bus shelter light systems can integrate easily into an existing bus shelter or be specified with a new installation along a route. The panels can mount on the roof of the shelter structure or be pole mounted nearby. The LEDs are integrated within a battery assembly and mount under the roof of the structure to provide lighting within the structure.

Advertising bus shelters can also use the solar to light the ad boxes that are sometimes on these shelter structures. The solar can power the entire lighting requirements of the bus shelter. These typically use LED strips along the edges of the ad box and are fed by the same battery pack as the overhead light fixture within the bus shelter. These systems require additional solar power and battery; however, allow for the advertising message not to be lost at night by travelers and others just passing by.

Not only do these systems save money due to lower installation costs, they save on monthly electric bills. Since the systems provide the power by the sun, there is no need for standard electric and to pay the utility company for the lighting. With the rise of utility power costs, this can turn into a huge savings in the long run. Definitely a win-win.

Here is Your Solar Flag Light Systems Comparison and Overview

Posted by SEPCO

12/2/14 9:30 AM

solar flag lightThere are many different types of flag light systems. Proper flag lighting etiquette states that you should light the flag all night long if you do not want to take it down at night. There are many types of flag light systems you can find online and offline, from $30 systems that operate only with a single charge and only last part of the night, to large industrial custom built solar flag light systems that will last days even if there is little sun due to weather conditions.

The small solar lighting systems you can purchase off large online stores and in big box stores typically provide about 8-10 hours of light for your flag if the solar is able to fully charge the batteries during the day. If you have an overcast day, or do not set it up just right, the light will not operate all night, leaving your flag in the dark. Make sure to read the complete specifications and installation on what you are purchasing if you want to ensure that your flag will stay illuminated all night long.

The smaller solar lighting systems will also require a battery replacement every year or two; depending the depth of discharge allowed for the battery used. Make sure the replacement batteries are easy to purchase and replace will allow your system to be able to reused year after year. If the batteries are not able to be replaced, this will end up costing more as you will need to replace the entire system when the batteries no longer hold a charge.

Custom built solar flag lighting systems provide all night lighting and provide much better backup for times of inclement weather. These types of systems come with a minimum of five nights storage and enough solar power to charge the battery in almost any weather conditions. They take into account the length of your night, the available sun in your area, and the amount of light required for your specific size flag to ensure good coverage.

These systems can still be quite small, depending on the type of fixture used and the sizing required for your geographical location. Fixtures range from small 3 Watt LED fixtures to much larger 25 Watt LED or more for larger flags. The fixtures can either be ground mounted or mounted high on the flag pole, depending again on the needs of the project. They can also be installed on a roof that is near the flag.

No matter what type of system you chose, make sure it will operate reliably and how you want it to. Don’t overlook the specifications and make sure you follow the installation instructions carefully to ensure your system operates as designed.

How to Have a Green Thanksgiving

Posted by SEPCO

11/20/14 9:30 AM

Green_Thanksgiving

It’s that time of year again. The smell of turkey cooking, green bean and sweet potato casserole and of course grandma’s pumpkin pie, but while we are thinking of what we are thankful for don’t forget about Mother Nature. After all, without her we would not be able to enjoy the food on our plate. It may be a little too late to completely rethink your entire plan for Thanksgiving, but there is still time to make a few adjustments to keep your Thanksgiving green and maybe even start some new family traditions to pass on to our future generation.

I have already bought my turkey, farm raised locally, and some of the other essentials for my traditional dinner, but I usually try to buy my vegetables and fruits as close as possible to my meal. There are few ways you can help the local economy and environment with very little effort. Let’s start before we even walk out the door. Grab your reusable bags of any kind to carry your haul home. Any kind of bag you have around will do even those old grocery bags you saved from your last trip to the store. I am guilty of always forgetting my cloth reusable bags when I go to the store so I do regretfully have a stock pile of plastic grocery store bags, since most of us already have them repurpose them. Reusing any extra bag you have lying around is greener than buying a new one, not to mention even easier on the wallet.

Where I live there are green markets that happen every Sunday or food co-ops, so it is easy to go pick up those last minute items that will be fresh and perfect for my Thursday meal. Most of the time not only is the food fresher, but it does not come with unnecessary packaging or chemicals and is usually cheaper. It is easy to grab a few containers along with your bags and put any loose items in them instead of the plastic produce bag. I can buy my lettuce without the plastic package and make sure I have all fresh leaves this way. Many times the farmers will have things like tomatoes, green beans, and blueberries in baskets that are already weighed out. Since it is going to be a big dinner buying in bulk should not be a problem and any extra you may have can be put in the freezer to use at a later time.

An obvious way to go green is to use regular plates and silverware versus the plastic utensils or Styrofoam plates that most of the time are not recyclable and can actually be harmful to the environment. If you don’t have enough of the same matching plates and silverware you could use the regular stuff for the kids table that way you don’t have to worry about the fancy stuff and kids usually don’t judge how pretty their plate looks. Use cloth napkins and repurpose those mason jars as flower vases or beeswax candle holders. Get creative and make some personal decorations. You can create your own potpourri by simply using cinnamon sticks and dried berries. My kids love making crafts and the family loves seeing what their works of art; my personal favorite is the traced hand turkey.

Over indulging is easy to do and something I am guilty of at every holiday meal, but food waste is one thing that can easily be avoided. Instead of stacking as much on your plate as possible start with small portions, it is easy to make a second trip and you are also less likely to consume as many calories. Try to make platters smaller so there is less leftover and not as much temptation to eat so much. I tend to drink water instead of soda as much as possible but it is easy to put more water in my glass then I consume. Any easy way to avoid water waste is to let guest refill their glass as needed and don’t worry about refilling when the glass is half full, or if there ends up being extra use it to water your plants.

Since we are putting smaller portions on our plate it is very likely we will end up with leftovers so try asking your guest to bring to-go containers and that way it doesn’t all end up in your fridge and thrown away because you can’t eat it all before it spoils. Being prepared with to-go containers will make you less likely to use saran wrap, Ziplocs, or a paper plate to send food home. If your family is anything like mine we always have a ton of desserts that we could not eat if we tried. A solution to this may be to plan accordingly so there are not as many made or give it to a neighbor, take it to work or even throw a dessert party for your kids’ friends.

Last comes the dreaded clean up. There are easy steps to take to reduce waste when cleaning up. First uses rags instead of paper towels and sponges and then hang them to dry after use. Turn the water off between wiping down counters and adding dish soap. In my home I try to use environmentally friendly cleaning products which are pretty easy to find and use much less harmful chemicals. Your guest can even get in on the action by properly disposing their waste into different containers that are marked recyclable or trash. Compost the food scraps like vegetable peels and eggshells which can be turned into garden soils. If composting is not an option check out different ways to use the remains for new meals like using vegetable scraps and the turkey carcass to make stock or soups by boiling them down. Leftover break crust or rolls can be used to make croutons for salads later in the week.

We would like everyone to have a wonderful Thanksgiving and try to keep in mind what we are thankful for and what is the most important, our family, friends and the earth we live on. Let’s all do our part to make sure that they are all preserved for years to come by doing all we can to keep it green.

Happy Thanksgiving from your SEPCO Family.

Ways to Save Money with Commercial Street Lighting

Posted by SEPCO

11/18/14 9:30 AM

Dania-Beach-4Commercial street lighting provides light along streets for driver safety, but the costs of installing, maintaining and monthly electrical bills can add up. There are steps you can take to reduce the costs and save money in the long run. Here are a few ideas, and feel free to share yours below in the comments.

 

Illuminate uniformly

Illuminating the streets uniformly provide the best lighting levels for security purposes. Spotty lighting does not allow for the safety that is needed on roadways and is basically wasting light and power. Provide even illumination and eliminate dark areas makes sure you are using every bit of energy to its maximum potential.

 

Switch to LED fixtures

LED lights provide better illumination while reducing operation costs and reducing maintenance. LED fixtures are more costly for initial purchase, but compared to HID, LPS and HPS fixtures, they can reduce the power consumption by a third or more and only need replacement once every 10 to 25 years. Best of all, LEDs use most of the power they draw for lighting purposes, unlike older style lamps that only use a small percentage of the power to provide light, the rest produces heat.

 

Provide maximum lighting when needed

Instead of running a 150 Watt LED fixture at full intensity all night, most streets can reduce the wattage of the fixture by lowering the fixture on the pole and only provide the lighting necessary for the application. There are few applications where high powered lights are required such as on a highway or major intersection. Also, reducing the fixture by utilizing dimming features with LEDs when there is practically no traffic, lowers the power usage for off peak times.

 

Install commercial solar street light systems

Using commercial solar street light systems in areas where there is no grid power nearby allows for the ability to provide the same safety and security in rural areas. These areas can sometimes be more dangerous than urban areas since there is more wildlife that can wander out in the middle of the road and without proper lighting, can cause fatal accidents. Mixing solar power with LED fixtures, maintenance will be minimal and there will be no electrical costs or worries for underground wiring to destroy the roads in these areas.

What other steps do you think would improve the efficiency and help save money when it comes to street lighting?

The A – Z of Solar LED Area Lighting

Posted by SEPCO

11/13/14 9:30 AM

Solar LED Area LightingSolar LED area lighting can be used for many applications ranging from small single LED lights along a pathway to large overhead lights for roadways and parking lots. Each system should be designed for the specific application and to provide the required lighting levels. Good research on the project application, design work and choosing of the final product will ensure that the end user gets exactly the type of system that perfectly fits their needs.

Small walkway lighting can be accomplished in multiple ways. From small off-the-shelf lighting systems for home walkways to larger corporate walkways using higher powered bollard fixtures vary in their design, costs and maintenance. The off-the-shelf systems typically each have their own solar panel, battery and all included in each fixture. These systems are not high powered, but can outline the area they are placed along. These systems require a lot of maintenance as their solar is only sized to provide a small amount of power with little to no backup from the battery, making the system use all available power nightly and reducing the battery lifespan dramatically; typically needing replacing every year or two.

Larger bollard fixtures can be installed in one of two ways; each having their own solar power system integrated within the bollard fixture, or multiple bollards powered off a single large power array. The single bollards that each has their own solar power system provide a little better storage than the small big box solar lighting systems; however, they will still require much more maintenance than a commercial lighting system. These types of systems have a flat panel on the top of each light requiring constant cleaning, especially in the northern snowy areas, and are more prone to vandalism. The batteries are typically only a couple day backup, which still produces a short lifespan of a battery. Large solar arrays powering multiple fixtures will provide a longer lasting system as there is typically a minimum of five nights autonomy and the solar is sized to replace the total usage every night in the worst case scenario, winter.

Other area lighting applications use larger fixtures such as floods and overhead light fixtures. These are much higher powered systems and provide large area lighting for parking lots, streets, perimeters, etc. These systems each have their own solar power assembly to provide the power to the fixture and operate as specified by the end user. These systems need to still be sized properly to ensure they are reliable and provide a long lifespan.

These larger projects have a considerable amount of customization options and discussing the needs of the project with the lighting designer will guarantee that the light specified for the project will meet the needs perfectly. Different distributions for different lighting applications can be used to customize the lighting system so that lighting is only installed where needed and not wasted. Also, control options provide specific lighting needs, such as dusk to dawn or specific timing, even dimming options that can be considered. Always make sure that the lighting representative knows the end project requirements before specifying any type of custom control electronics.

Next time you are looking to light up an area and need a solar option, consult your solar lighting specialist to help you design the perfect system tailored to your specific needs. From big to small, solar LED area lighting can be a great choice.

7 Questions That Level the Commercial Solar Lighting Playing Field

Posted by SEPCO

11/6/14 9:30 AM

Commercial Solar Lighting Playing FieldSolar Lighting is not all the same. Yes, they include panels, batteries, light fixtures, control electronics and brackets for mounting the fixture and solar; however, there are many differences when deciding the best solution for your project. Here are the 7 questions you should ask to ensure you are getting exactly what you are looking for and to be able to compare the offerings of different solar lighting manufacturers.

  1. What is the type of solar module used?

Is the solar module single or multi-crystal panels? Mono (single) and Poly (multi) crystal panels, though vary in efficiencies, are both great for energy production and work well in off grid solar situations. Making sure you are purchasing quality solar panels will ensure their long life span and energy production. Some unknown brands of solar panels will state that they provide the same power; however, they typically cannot stand up to the test of time like well-known solar panel manufacturers do, as well as back their products and stand by them on the warranties.

  1. What type of fixture is being used?

All fixtures are not equal. Finding out the lumens per watt provided by the fixture will allow you to determine the light output of the fixture. Also, you need to find out how long the fixtures have been in production and if they are from a reputable company. You don’t want a fixture that hasn’t been field tested for some time by a company that has no experience in the lighting industry. Especially with LED fixtures, you want to make sure the fixture will last as long as the system does.

  1. Is there protection for the solar?

Protecting your solar power system is a great way to safeguard that your system will stay standing for years to come. Some companies, such as ours, use panel pans to protect the fragile backside of the solar panels. Vandal hardware can also be used to make sure that the system cannot be easily removed from installation site. Finally, higher quality solar panel manufacturers use tougher glass material on the front of the panel so not to get damage from wind-blown debris and storms that include hail.

  1. What are the controls of the system?

Knowing exactly how your system will operate will guarantee you are getting exactly what you are expecting from your solar lighting system. Some companies hide in the fine print that their systems in fact operate all night; however, after so long, it will be at a reduced wattage, sometimes as low as a fraction of the original wattage requested. Make sure you get the control profile of the system that matches your needs. If dimming is an option on your project, great, but make sure you know how much the fixture will be dimming. If no dimming is allowed, make sure to read through the fine print. Learn about all the control options available before you finalize your design.

  1. Is there enough storage for inclement weather?

Five days storage is the minimum required backup for most areas; however, the further north your installation site is, the larger the storage will need to be. Five days does not cut it in New York like it does in Texas since the depth of discharge on cold batteries is much larger than in the warmer weather, lowering the life of the battery and increasing down time and maintenance costs. There are also many more overcast days in the north during the winter than in the south. Know the amount of storage that is appropriate for your area and verify that there is enough storage for your systems to operate all winter long.

  1. What type of materials is used in construction?

Materials may not seem like a very important discussion initially, but the way the systems, including the mounting brackets, fixtures, etc. are constructed will determine how long your system will hold up in the field. Marine grade aluminum is one of the best materials used in the industry since it does not corrode or deteriorate and can last as long as the complete system. Other metals, such as steel, tend to rust (unless galvanized) and powder coating the system can also improve the life of the metal as well. Plastics are a definite no-no in the main construction of the system as sunlight tends to break them down and cannot withstand the long lasting needs of a commercial solar lighting system.

  1. What type of pole is the equipment mounting to?

Finally, what type of solar light poles is the equipment mounting to? Is it round? Square? Steel? Aluminum? There are many questions that need to be asked before installation. We never recommend using a square pole since the solar power system needs to face due south and this does not always allow for the fixture and the solar to face the correct directions. A round tapered pole is best as the taper allows for added strength to withstand the added weight and EPA (effective projected area) of the system as a whole. If you purchase the pole from the manufacturer, make sure it will withstand the local AASHTO wind ratings, is made with a long lasting material and compliments your project as a whole.

Implementing Solar LED Outdoor Lighting for Commercial Property Saving

Posted by SEPCO

11/4/14 9:30 AM

ABC-Domes-7One of the primary problems facing any commercial business operator is making sure their business stays profitable. If you can't make money you're bound to have trouble keeping a business afloat, it's just the nature of the beast. Of all the things you could do in hopes of cutting costs one that's probably going to be the least detrimental to health of your company is looking into switching out your source of electricity. Standard electric can be a bit costly, not only due to rate increases from whichever company is supplying your power, but also the upkeep of the system and the constant changing of the bulbs in your system. As a result of this cost many businesses have been taking steps to focus more on use of solar LED outdoor lighting systems. These systems will allow you to cut the cost of having to pay one of the power companies for the sake of lighting your business and the surrounding parking area. Solar power is the best option these days due to its cost cutting ability as well as its ability to renew itself day after day. If you're looking for a way to light your business, you can't really do much better than to switch over to solar power instead of standard electricity.

There are a ton of benefits to going solar over standard electricity; one of the primary positives is the fact that the government looks very kindly on people going green. When you choose to go solar in place of a standard electrical hookup you're eligible for certain tax breaks as you're helping to turn around things in favor of the environment. Not only are you able to get apply for, and receive, tax credits for the work you're doing in swapping from standard to solar power, you also may have the opportunity to sign up for grants to pay for your project. If you're looking to make your business turn as solid of a profit as possible you're going to want to go with solar LED outdoor lighting, it's one of the best moves that anyone can do while starting things up. Solar power has grown by leaps and bounds in recent years and it appears that it's growing even more every day, with the potential for printed solar panels on their way to the market soon it would seem that solar will finally become much more affordable than in years past as well.

With the steady stream of companies switching over to the solar power sources for their lighting, one of the top choices has become to go to the LED lights in the system. LED lights are amazing due to their low wattage output while not losing any of their luminosity. LED bulbs have a tendency to be incredibly bright which would help guarantee your location is well once the sun goes down. Between the low wattage use, the high visibility created, and the length of time that the bulbs last you're looking at an incredible cost savings. This is typically one of the biggest expenses a business could have up front; going the solar LED way is the best option to keep your location well lit so that nobody is injured on your property. You've got plenty of choices when it's time to change out your lights, of all those choices, the combination of LED and solar lighting is easily the best bet for saving energy, and more importantly saving money. You can consider your options, but in the end you're not going to find anything better than LED lights run on a solar powered system.
