What Light Pollution Means to the Future of Lighting

Posted by SEPCO

4/6/15 10:00 AM

Florida Coast by The City Dark DocumentaryWe are from a small town, so the difference between us and a place like New York City as far as light pollution is way different; however, we all experience some form of light pollution. Light pollution isn’t something you think of, but does it really affect us?

Light pollution is the way light shines upwards illuminating dust and debris in the air and creates a cloud effect that blocks out the night sky. Since the beginning of time, we have depended on the night sky for information in regards to location, seasons, direction, etc., but with modern technology, we don’t rely on this for our information, but does it still affect us? And if so, what can we do to change the light pollution factor of areas?

Granted, all light cannot be lost at night and we will never have the dark sky at all times at night that happened hundreds of years ago, but light pollution can be reduced. Providing light in the areas they are required at the times they are required, and using dark sky compliant fixtures, will lower the amount of light pollution and increase our visibility to the night sky. The US spends 1.5 billion dollars every year on wasted energy due to light pollution. Towns all over the US are setting light ordinances moving towards using full cutoff fixtures only to preserve the night sky as well as reducing costs.

I recently wanted a documentary on this very subject called The City Dark and learned a lot about how we see the night sky in different locations. The films looked at the light in New York City and out in Arizona and the differences were amazing.

The light pollution doesn’t just affect animals, but humans as well. The US National Library of Medicine did a study on the health effects of light pollution.  Decreased melatonin produced in the body effects our hormonal system and sleep cycles. Melatonin deficiencies cause an increased risk of cancers, especially breast cancer, and it is unknown what other risk factors this produces. Many sleep disorders are also caused by light pollution. The study says we are only at the tip of the ice burg in research at this point.

Turtle Friendly Solar Light in Bradenton Beach FloridaSo what does this mean for the light industry? California has taken the light pollution into consideration, as well as the wasted energy, and implemented Title 24 Energy Efficient Standards. These standards are for residential and non-residential areas to decrease their use when the light is not required, like after a facility is closed, and using full cutoff fixtures with motion sensor or adaptive lighting controls. This is set to lower the consumption of electricity in the state.

Other states, like Hawaii, require LPS lamps for their telescope areas with a full cutoff fixture so there is little to no light pollution and any light will not affect their telescopes when looking at the night sky. Areas like Florida are required to use amber color light with full cutoff along coastal areas due to sea turtles. All these different steps are being taken to help reduce light pollution and the affects they have on nature.

What can you do? Take steps to not waste light where it is not needed, provide high efficiency lights, look at local ordinances when installing new lighting and turn it off when you don’t need it. Small steps can be taken in both a residential and business to ensure that we all do our part in reducing the impact we have on the environment and us as a species.

How Does A Solar Light Work

Posted by SEPCO

3/30/15 10:00 AM

How Does A Solar Light WorkWhether you are talking about the small garden stake lights you find at any big box store or a commercially produced solar lighting system, they provide the same functionality. The difference between them is in the design. Here is a basic overview of how does a solar light work.

There are four major components to any light; the solar panel, battery, control electronics and the light fixture. During the day, the solar panel produces power to charge the battery by the photons produced by the sun’s rays collecting and stimulating electrons in the silicon cells. These electrons are knocked off and collected by the wiring of the solar panel and fed to the battery for storage. This happens from the time the sun starts to rise till the sun is set. Full power production doesn’t actually occur till mid-day; however, the panels can produce power in almost any circumstance there is sunlight.

The battery then stores the power produces during the day. The control electronics determine when it is dark out by noticing the reduced power production of the solar panels. This triggers the system to stop feeding the battery and turn on the light fixture. The light fixture will then feed off the battery for its energy to produce the light. The fixture then operates the schedule profile it is set to operate, whether that is dusk to dawn, or in some lights, when the battery is empty. The light will then turn off when the battery becomes too low or the control electronics notice there is power being produced by the solar panel again.

This cycle continues day after day.

The only differences between solar light systems are the operation profile and system components that are used to build the light. Small lights you find at a home improvement store for your garden provide typically one night’s worth of power. They charge small batteries during the day and operate the light fixture only as long as the batteries have charge. This full depth of discharge only provides a short period of time before the batteries would need changing.

Some larger solar lighting systems manufacturers think the above design is okay for commercial practices; however, there is a large system failure since there are differences between locations and applications that need to be considered when designing the system. Large commercially produced lights must take into consideration the project location, the application that it will be used, and other project specifics. A minimum of five nights autonomy, or backup power, should be implemented to lower the maintenance of the system and provide enough backup for little to no failures when there are periods of inclement weather.

Light fixtures specific to the application should also be used. If you have a large area that requires lighting, a small spot light will not produce the required lighting levels. Instead, using light fixtures that produce specific optics and distribution patterns will ensure the light fixtures meet the needs of the project. The lumen output of the fixture, not the wattage, also needs to be taken into consideration. A lighting analysis and calculations can show all this and can be provided by any reputable solar light systems manufacturer.

So that’s basically it. Sun charges the batteries with the help of solar panels during the day and then the light fixture feeds off the battery at night.

Benefits of Off Grid Solar Power Light Systems

Posted by SEPCO

3/16/15 10:00 AM

Off Grid Solar Power Light SystemThere are two types of commercial lighting systems, grid powered and off grid powered. Solar powered light systems that are off grid provide different benefits to grid tied light systems such as: light when there is no power for additional safety and security, lack of electric bills, easier installation, and light wherever you need it. Customizing a system for each application will ensure that your light system meets the needs of your project completely.

Light with No Power –

If you live in an area that is prone to blackouts and brownouts, then off grid solar power light systems provide you the safety and security knowing that your lights will still function. Since they are not powered by the grid, if the electrical company has an issue, your lights will still operate just as they are supposed to.

If you area is not effected with these issues, the benefits are similar since you can rely on knowing that no matter what is going on with grid power in the area, your lights will still function. This provides additional safety and security and is popular for military and government facilities since the inception of the Federal Energy Policy Act of 2005 that states federally owned property and buildings are mandated to materially reduce current energy use while also improving energy “security,” by employing renewable power that operates independent of electrical utility grid.

Lack of Electric Bills –

Off grid power systems do not use electric from the grid and therefore cost you nothing in monthly electric bills. Since the inception and popularity of LED fixtures, the maintenance on such systems has also reduced greatly. The only thing that requires maintenance now on a standard solar lighting system is changing the battery every so often. Depending on your nights of autonomy, this can vary greatly between manufacturers. Ask your manufacturer how much their system’s autonomy, or backup power, is standard and what their maintenance schedule is. The more autonomy, the longer the batteries will last and the lower the maintenance costs will be.

Converting your existing electric grid powered lights to solar is not always the most cost feasible if everything is operating correctly. Instead, making simple changes such as switching out the fixtures to LED fixtures, installing control options that reduce the lighting, or even turn in off, when it is not required will help reduce power bills greatly. If you are looking for a way to eliminate the electric bill of your current lights, installing grid tied solar, after making the other changes, based on your average sun insolation and usage will allow for a NET Zero project.

Easier Installation –

Off grid solar power light systems provide a much easier installation. The light can be located where it is required. Unlike the constraints of traditional grid powered lighting where you have to use existing poles and infrastructure, or complete costly trenching to put the power where you need it, solar powered light systems can be installed just about anywhere. This lowers costs by allowing existing structures and areas to be undisturbed for installation. This is especially helpful in cases where grid power is far from the location of where the light is required and times where you discover, after doing upgrades to an area, that the power lines are deteriorated and would need replacing.

Light Where You Need It –

Like discussed in installation, the light can be placed exactly where it is required. Have a dark area in a parking lot? Or a pathway around a park where there is no electricity? Solar powered light systems can be installed in just about any location. If your lights are needed in a shady area, the solar power systems can be installed up to 50’ to 100’ from the actual light so that the solar can be exposed to full sun while your light can be installed where it is needed.

Now that you know some of the benefits of off grid solar power light systems, you will be able to make a better decision when determining your needs. Want to move forward with your off grid solar light project? Learn about common design questions that need to be answered before a system is configured. This will ensure that the manufacturer is designing a system that will meet the needs of your project.

What Is EPA and Why Does It Matter?

Posted by SEPCO

3/9/15 10:00 AM

WindandEPA
EPA stands for Effective Projected Area and is used in many applications, including solar lighting system design, construction and installation. The EPA is calculated to help determine the strength of the pole needed to provide support to the solar lighting system during wind events. This calculation takes into consideration the entire area that the solar power system and light fixture will take up at the top of a pole and helps manufacturers determine the size of pole, the type of anchors used, the embedment and foundations used at installation, and the types of brackets required to keep everything mounted during a high wind event.

EPA and AASHTO Standards are used when calculating the requirements for the pole used in any solar lighting application. These two factors are used to determine the size of pole required to ensure that the light will still be standing after a wind event up to a certain mile per hour.

The EPA of any system varies depending on angles, shapes, and size of the systems. Even the shape of the pole can change the EPA of a complete system as square poles have a larger EPA than a round pole. When designing a solar power system, the angle of the system affects both the EPA and the solar power production of the system. All these factors must be taken into consideration when designing a project as well as ensuring the installation will withstand for years to come.

So why does this all matter? When designing a system, the EPA of the complete system needs to be taken into consideration to ensure that the solar power assembly will not blow apart during a storm, the pole won’t be knocked over due to the large area at the top of the pole, etc. To find local AASHTO wind load ratings, you can look online or talk to your pole manufacturer, solar lighting specialist or local engineering firm.

Different locations, such as mountainous areas, coastal areas and areas around the Great Lakes have different wind speed requirements than other inland areas. Consulting a local authority is the best way to ensure you are purchasing equipment that can stand up to these windy areas. The best way to determine the requirements of the project is to:

  1. Determine the site location

  2. Determine to total weight and EPA of the equipment

  3. Determine the wind load requirement

  4. Talk to your manufacturer to ensure the pole can hold up

If you are still unsure, additional engineering calculations can be performed. These typically are a small fee ranging from $500 - $1000 for signed and sealed calculations. These calculations are performed by a third party engineering firm.

In the end, talking to your manufacturer or local engineering firm will help you determine what size and type of pole will ensure your equipment will withstand local wind events. Learning about different options when it comes to poles will also educate you on the final decision when it comes to system design. Check out: My Pole or Yours? Why Solar Light Poles Differ

A New Way to Think About Lumens and Watts

Posted by SEPCO

2/16/15 10:00 AM

Lumens and Watts

I keep being asked to meet the Lumens or Watts from a HPS, MH, or just about any other type of light, but this isn’t comparing apples to apples. This is trying to compare apples to spaghetti (I love spaghetti). A while back, I wrote an article Wattage vs Lumens: Know the Difference for Better Lighting to help readers understand the difference between comparing a 400 Watt HPS lamp to a 30 Watt LED, but I think it is time to expand on that.

A Lumen is a Lumen and a Watt is a Watt; however, the two don’t really have much to do with each other in the LED world. One LED may produce only 50 Lumens per Watt, where as another may produce closer to 100 Lumens per Watt. Therefore, one company’s 30 Watt fixture may be brighter or less bright than another company’s. Most companies publish their efficiency ratings on their specification sheets, and if you don’t find it there, contacting someone at the company or a local representative will help you determine exactly what the light output of a certain LED fixture is.

Another huge misconception is how many Lumens it will take to light a specific area. Other lamps, like some 400 Watt Metal Halide lamps, produce around 36k Lumens; however, these lumens are spread out shining in all directions, not just down. This means that only a fraction of the 36k Lumens actually reaches the area below the fixture.

Directional LEDs are very different. All of the light is directed to a specific direction and produces task specific lighting. All Lumens are in the area they are required and not wasted in areas where they are not needed. This lowers the amount of Lumens required for a specific lighting task while also lowering the wattage of the fixture draw and the electrical requirements.

For example: a street light requires the light to be shone down on the street, possibly even on a walkway / sidewalk along the street. The light is not needed on the building across the street, nor is it needed up high in the sky. The same concept goes for a coach fixture in an HOA, a sign light, parking lot light, etc. The light should be specified to the task that is required, and light level requirements should be figured before determining the Wattage or Lumens that it will take to meet those requirements.

If light level requirements are unknown, then standard IES requirements for most applications can be a good starting point for just about any project. Standard IES for a parking lot, for example, is .2 foot candle average. Depending on the height of the fixture, the Lumens per Watt produced (efficiency rating), and a few other factors, this may be achieved by a range of different fixtures and fixture Wattages available.

The best way to determine what you need for Wattage and Lumens is to have a lighting plan completed. Lighting designers will place the lights where they are needed within a design and help determine what is needed to properly illuminate a space. If there is dimming being used, you can always ask for one light plan showing what the light output will be on full intensity and an additional light plan to show what the light output will be at dimming. This way you can verify exactly what the light fixtures will do at any point.

Remember, there is no one-to-one comparison when it comes to Lumens and Watts, especially when changing companies and types of lamping options. Instead of asking for an equivalent fixture, ask for a specific lighting level requirement and you will see better results. And always ask for a lighting plan if you are unsure…you may be surprised at what the lighting plan reveals.

Determine The Best Way To Implement Pathway Lighting In 3 Easy Steps

Posted by SEPCO

1/19/15 9:30 AM

Solar Powered Pathway LightingPathway lights cover a myriad of different areas. They can be small walkways like in front of a house or through landscaping, or large walkways like those around a college campus or park. Adequate lighting allows for people along the pathway after dark to be able to see where they are going and provide visibility to their surrounding areas. To ensure these pathways are properly illuminated, there are a few steps to follow to determine what sort of lighting would be required.

Step 1 - Determine what type of pathway will be illuminated.

Small pathways that are only a foot or two wide in gardens or along a home do not require much lighting other than illuminating the footpath as there is typically other lighting to illuminate the surrounding area. These are typically illuminated with small pagoda or bollard style lighting that only provides the light at a very low level.

Larger pathways that are over three feet wide will require high powered bollard fixtures or overhead fixtures to provide a large area of light. With LED lighting and advanced optics, these fixtures can provide lighting to just the path, or the path and surrounding areas for added security. These areas also characteristically require even illumination which cannot be provided by small, low powered fixtures.

Step 2 - Determine how to power the light fixtures.

These types of fixtures can be either standard grid powered or solar powered. Standard electrical power requires the use of underground wiring and should be implemented in the planning phase of a project to not disturb the landscaping or require for breaking up concrete to trench under. The electrical lights can be set on a timer to only be on during the times they will be needed, or the lights can operate all night.

Solar powered pathway lighting such as solar bollards or solar pagoda lights can be designed two ways. The first way is to have every light have its own solar power source, typically fixed to the top of the fixture. These fixtures provide the lighting where needed; however, they are prone to vandalism, and due to the flat panel design, do not get the full advantage of the sun, especially when there is inclement weather such as snow or cloudy weather. These types of fixtures also can only be located in sunny areas and cannot be installed under trees or nearby something that can cast a shadow on the solar during the day. They also do not typically operate all night or have much for backup power if they are not able to be fully charged by the sun the following day.

Using a single solar power source that is remotely installed with full access to the sun to provide the power for multiple fixtures provides added security since these types of solar power assemblies are more vandal resistant and can be located in a more secure location or high up on a pole with the fixtures installed anywhere they are needed, even in the shade. They are typically mounted at an angle facing south to take full advantage of all the power the sun can provide. The solar power assembly provides more power than integrated fixtures with solar as well as much more backup power for inclement weather periods.

Solar powered pathway lights are the perfect solution for lighting an area that does not have electrical power nearby or as an afterthought to an existing area. They can also be set on a timer for specific operation times or operate all night for areas, such as a hospital, that are open all night.

Step 3 - Determine the architectural requirements of the area.

Is the pathway located in an industrial or historic area? Are there fixtures that would need to be matched already located nearby? With the number of light fixture styles available, there is sure to be a fixture to meet the architectural needs of the project.

LEDs have advanced and can provide similar lighting levels for each fixture style. Learn about the fixture designs and talk to your local lighting company to determine if they can meet your requirements. Since LEDs are easily integrated with solar power systems, the requirement for a solar option no longer keeps you confined to only a small selection of fixtures.

Following these three steps will help you determine what the best solution to your project is. Speak with your lighting representative to see what solutions they can provide you for your project and all the options they have available to meet your needs. With the advancements in the lighting industry happening every day, now is a great time to explore your options in solar lighting.

Quick Overview of Sign Lighting from Big to Small

Posted by SEPCO

12/11/14 9:30 AM

Signs provide advertising and information to travelers day and night; however, if they are not properly lit at night, miss visual impact by someone driving by. There are many ways to light up a sign at night, including the use of solar when electric is not readily available. Here are some great tips and information for different types of sign lights from big to small.

 

Large Billboard Salt River Devco

 

Large billboard lights require quite a bit of lighting to see easily at night. Billboards are typically used for advertising along highways of local businesses and can generate great traffic for these businesses from travelers. Making sure they are properly illuminated during the night time allows for your message not to be missed. A typical billboard needs around one bright fixture every 10 feet to allow for proper illumination levels and to make sure none of the message gets left in the dark.  These can easily be solar powered as the solar panels can be mounted on top of the billboard to charge the batteries during the day and then power the lights at night. Best of all, there is almost never any shading concerns on a billboard. Since billboards are typically installed in the middle of nowhere and have no ability to install typical electrical grid lines, solar is a great option for these large signs.

 

Large Monument Sign Moraine Valley Community College

 

Large monument signs for communities, offices, businesses, etc. can also require multiple fixtures to properly illuminate the sign. These styles of sign lighting systems have fixtures mounted near to the ground angled upwards towards the sign face. These signs can be located along the side of a roadway or in a median. You can either decide to light up just the logo and information on the sign, or the entire sign along with surrounding landscaping. Solar can easily adapt to these signs as well since there is not always power located where the sign is installed, especially in a median, and the trenching involved with bringing in standard electrical power is costly and tears up the surrounding areas.

 

Small Sign Savannah HOA

 

Small signs typically use a single flood fixture and require much less lighting than larger signs. These too have ground mounted lighting; however, the light fixtures can also be mounted from the top of the sign. These too can easily be powered by solar power systems and typically require small solar power systems. For extra impact, additional fixtures can be used to light up the surrounding landscape to really light up the sign area.

 

Internally Illuminated Sign Denver Children Advocacy

 

The final topic to discuss is internally illuminated signs. These are typically either on a building face or stand alone along a roadway. Internally illuminated signs mostly used long fluorescent tube lights; however, there is a huge transition to LED strips to new signs as well as upgrades to older sign boxes. There are many options available with LED lights that can be installed within a sign box and can be as comparable to sizing in regards to the required lighting as a standard flood system to requiring much more power than an externally illuminated sign.

 

Speak with your sign company when deciding what type of sign you are having designed and the options available when it comes to lighting. Knowing the lighting requirements before the final sign is built will help you determine the best type of lighting and to get the most for your money. Most sign companies work with lighting companies directly and can help you determine what the best course of action is. If you are requiring a solar solution due to a lack of traditional power where the sign will be installed, contact your solar lighting designer to create the perfect solar sign lighting solution for your sign.

Getting Better Solar Lighting Results by Following 3 Simple Steps

Posted by SEPCO

12/9/14 9:30 AM

Better Solar Lighting ResultsPurchasing a solar lighting system for any application can be a daunting task. There are so many options and decisions to make that you can easily get lost in the specifications. There are three simple steps you can take to ensure that you at least have good results with your system, no matter what the application.

Step 1

Use LED fixtures that provide a high Lumen per Watt output. This information can be found on any specification sheet, and if it is not right there, ask for it. A high wattage LED fixture does not mean that it provides bright lighting; it all depends on the Lumens provided from the LEDs. Knowing the available Lumens per Watt for the LEDs can help you determine which fixture would provide the required light. Want to know more about the difference between Watts and Lumens, check out Wattage vs Lumens: Know the Difference for Better Lighting.

Step 2

Make sure your solar power system provides enough power during the day and provides plenty of backup storage. Solar lighting systems should always be designed for worst case scenario since if you use more than you put in, the system will begin to fail. Sizing your system with summer or even yearly average sun will not ensure that your system will operate when the days are short and nights are long. Make sure your system always provides around 20% over for power generation and you have a minimum of five nights autonomy for those times of inclement weather. This will guarantee your system operates even when the weather is bad for days at a time.

Step 3

Make sure to follow installation instructions carefully and provide shade free south facing site for installation. Reading the installation manual before starting the installation will allow you to decide if you have everything necessary and alert you to any special needs of your system. There can also be labels on the system itself pointing you as to what is needed. Finally, ensuring the system faces directly south and has no shade on the solar panel all day will make sure that the solar lighting system can stand up to the test of time. If there are trees nearby, make sure they are trimmed well.

Following these three simple steps will guarantee that your solar lighting system will provide the best result possible.

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.

Give Me 10 Minutes, I’ll Give You 3 Truths About Solar Lighting

Posted by SEPCO

10/9/14 9:30 AM

SolarLighting1.jpg-1There is a lot of information bouncing around about solar lighting. Some people love it, some people don’t. There are many pros and cons with solar lighting, but the one thing that always seems to get lost in the shuffle is the reason behind using solar lighting systems. Here are some truths behind solar lighting:

  1. Truth – You want a green option, but can justify the costs.

The initial costs behind a quality commercial solar lighting system can be daunting; however, incentives are available that help lower the costs. Also, take into account the lack of electric bill and very limited maintenance costs that are needed for the next 25+ years. With rising costs of dirty energy sources and lowering resources of these forms of energy, solar is a great option and the costs can easily be justified.

  1. Truth – What do you do when there is no power nearby?

When no power exists nearby, there are two options: trench in standard electric or install solar lighting systems. Trenching in power is a costly expense, not just bringing the power where it is needed, but also all the damage that needs to be repaired from the trenching. Will this tear up a parking lot or roadway? What about additional construction that may be done in the future, will it damage the underground wiring that you just brought to the site? Solar lighting systems are all in one systems and do not require underground trenching or wiring that can be disturbed over time or damage a property. Everything is on a single pole and completely stand alone from the other lights.

  1. Truth – I have electric already, but want to look at using solar instead.

This is typically not a justifiable cost since there is electric already at the site. Using off grid solar lights when there is already electrical lights won’t really save you anything immediately. The payoff or ROI is quite long when electric already exists. There are a couple things you can do to provide a green solution while not having to go completely off grid. The first thing that needs to happen is switching to LED fixtures to lower the power consumption. Next, you can switch to grid tied solar lighting systems that feed the grid during the day and then the lights draw from the grid at night. If done right, you can have a NET Zero project that is sized properly so you generate during the day what you use at night. Finally, you can use a battery backup system where the grid and solar work together to charge the batteries and then the lights operate off the batteries at night.
