Reduce, Reuse, Recycle: What about Repair?

Posted by SEPCO

Repair

I know since I was a little kid that we have been learning about the 3 R’s of living a more green life; Reduce, Reuse and Recycle. Something that seems to have fallen into the shadows many years ago is Repair. Instead of getting rid of that broken item, repair it to allow it to continue to be useful. A lot of things you can repair at home, others may have to be taken into a shop or have a technician look at it, but in almost all cases, the item can be repaired.

I came across this great article, The Forgotten ‘R’: Repair by Elizabeth Royte a while back and it got me thinking. How much stuff do I myself, a green professional and person, get rid of over the year that is broken but can actually be easily repaired? Now, instead of just throwing out that carpet shampooer that won’t do what it needs to, or the drawer of the fridge that is cracked, it is time to get out the tools and fix this stuff. If I can’t do it, I’m sure there is a repair shop somewhere in my town that can fix things.

One thing noticed in the article is the disappearance of repair shops. Manufacturers are making products that they want you to throw away once they break so that you purchase new products. There is something really wrong with this mentality. We have become a wasteful society, and with the increase of global warming and waste being a huge contributor to this, we should be looking for ways to reduce our impact by repairing items. Now, repair shops are starting again, popping up all over.

What to do with that item that just isn’t repairable, where no amount of glue, wiring, screws, etc. will ever make it perform the way it was intended again? We recently looked into Upcycling where you take unusable items and turn them into something new and amazing. If that item really can’t be repaired, look at it from a different angle and see what it may be able to become and breathe some new life into it. Save the unused tiles from a project and create a new top for that scratched up table that you don’t know what to do with. Go online; there are thousands of ideas all over the internet. Don’t know what to do with that broken item and don’t have the time to turn it into something new, advertise it on Craigslist or Freecycle and let someone else take a crack at it.

The takeaway: Let’s all work together to expand the iconic 3 R’s and add a forth by repairing items that break.

Tips and Trick for Solar Outdoor Lighting Troubleshooting

Posted by SEPCO

Solar_Outdoor_Lighting_Troubleshooting

Solar outdoor lighting is a great way to showcase your green initiative and provide great lighting in all types of areas, but what do you do when they malfunction and don’t come on when expected? There are a few tips and tricks to troubleshooting solar lights that help you determine what the issue is. Here are a few of the most common issues that work for both commercial and residential solar light systems and how you can determine what the issue may be.

1. Are they coming on, but turning off before they are supposed to?

Sometimes your lights just don’t last as long as they once did and this is typically caused by batteries dying. With commercial solar lights, the batteries should last five to seven years if properly sized for the application. If it is coming up to that point, it is time to contact the manufacturer and get replacement batteries. Small home solar lights have batteries as well; however, these typically last a much shorter time and can easily be replaced by purchasing rechargeable batteries from your local store. Remember, batteries only have so many cycles before they just go bad and need replacing.

Another issue could be the solar panel is dirty and not producing the required power to charge the batteries fully. This is a simple fix and one of the easiest things to check. Look at the solar panel and see if it is dirty, then follow steps on cleaning the solar panel and see if that helps the system function properly. This doesn’t need to happen often, especially if your panels are at an angle and it rains often enough to keep dusk and grime from building up on the panels.

Finally, are the panels shaded by something that has grown in the way? Trees and surrounding landscaping grows over time and can cause shading on the panels, not allowing them to charge the batteries fully. Make sure there is nothing taller than the panels near the south of the system’s installation. Solar panels need direct sunlight all day and even the smallest amount of shade changes the output of the solar panels.

2. Are the lights not coming on at all?

This could be one of two issues if the lights worked at one point; the battery as above, the lamp or a blown fuse. If the battery is what you think is the problem, replace them. If it isn’t the battery, it is more than likely the lamp. A lamp only has a certain life span and they need to be changed out every so often, just like a light bulb in your home. There are exceptions to this rule such as LED technology. Most LEDs last 15+ years; however, if you are using CFL, HPS, LPS or metal halide, they can die much sooner. Determine what type of lamp is operated by your solar lighting system and figure out if it is time to replace the lamp or not. One suggestion we would give is if it is time to change out your lamps, look into utilizing a LED fixture. Not only will they last longer, they will give you more light for the same power draw, a complete win-win.

The last thing that could be going wrong seems like the simplest thing, but it can render your system completely dead. A blown fuse will terminate all power from flowing through your system and not allow the light to come on at all; however, it is a simple replacement with a new fuse the proper size and your system will be up and running immediately. All SEPCO systems come with an extra fuse in the battery box just in case of this situation.

Now that you know the basics to troubleshooting your solar lights, you should easily be able to figure out what is wrong and how to fix it. Need additional troubleshooting help? Contact your manufacturer for additional support.

Achieving NET Zero with Off Grid vs Grid Tied Solar Lighting

Posted by SEPCO

8/7/14 9:30 AM

Companies today are looking for ways to improve their energy efficiency, lower their costs and increase their sustainable practices into their business model. One of the most effective ways for a company to complete all three tasks is to look for NET Zero solutions. NET Zero is when a business or home uses the equal amount of power that it produces on a yearly basis. There are times where a building may use more than it produces at one point of the year; however, it averages out when the building produces more energy than it uses.

Lighting is a huge part of the energy usage of a business; however, there are options to help achieve NET Zero when looking at exterior lighting utilizing solar lights. There are two main types of solar lighting systems that can help achieve a NET Zero application. The first is off grid solar lighting systems that utilize no power from the grid. The second is grid tied solar lights that feed the grid during the day and use the power from the grid at night.

Off Grid Solar Lighting

Off Grid Solar Lighting

With off grid solar lighting, the solar panel is sized to charge a battery bank during the day that is large enough to feed the lights all night. The solar power system is determined by the light fixture Amps, amount of sun in the worst case scenario (typically winter), the run time required and the amount of battery backup that is required for that area, a minimum of five days autonomy is typical in a good system. These systems do not rely on the grid power and are completely NET Zero from installation.

In areas with little sun in the winter, there are restrictions to what wattage lamp can be used. High powered LEDs will require much larger solar arrays and battery banks in the northern areas, making the systems costly for initial purchase. This can be reduced by reducing the run time of the system (say only till 2 hours after the business closes and then on again an hour or so before the business reopens). Working with a solar lighting professional or a lighting designing company can help you find the best solution to fit in your budget and provide the necessary lighting requirements for your application.

Grid Tied Solar Lighting

Grid Tied Solar Lighting

With grid tied solar lighting, the solar panel is sized to the average sun hours and does not include a battery bank. The solar feeds the grid during the day and the grid runs the light fixture at night. There are still sizing constraints with this type of system to achieve NET Zero. The solar panel needs to be sized to provide enough power that it equals the usage of the lamp. A large 250 Watt Metal Halide lamp will require a much larger solar power system than a 90 Watt Equivalent LED fixture. LED switch outs are recommended in grid tied solar lighting applications.

These systems are much less costly than off grid solar lighting systems and have a quick ROI, but are not a good option in areas that do not have grid power already installed or easy access to grid power. If there is not electric currently at the site, off grid solar light systems are the better solution since there will be no trenching of the area (especially roadways and parking lots) and the expensive drop down and cables required to run the electric to the area.

Each option has its benefits to help a business achieve NET Zero certification on their new or updated facilities. Working with a solar lighting company that understands your needs will ensure that you have a system designed to specifications and will provide a great ROI and long life.

Solar LED Road Lights Provide Great Lighting to All Types of Roadways

Posted by SEPCO

8/5/14 9:30 AM

Solar_LED_Road_LightsRoadways are our connection to everything and everyone. They can take us from the east coast to the west coast and anywhere in between. Raphaël Renaud said “Roads and streets, the central nervous system of complete urbanization”. But if you’ve ever driven late at night, you know how difficult it can be to drive on dark roads.

This is where solar road lights can come in to save the day. These types of lighting systems can be installed in any location.

Don’t mistake me for talking about the solar roadways. As this is a great idea and can completely change how our roadway are completed, how they respond to our world, and all the many benefits that comes along, this is not what I am referring to. I am talking about the solar LED road lights that provide overhead lighting on the ground below as travelers drive down the road.

Benefits of solar LED road lights include:

  • Reduction in night accidents
  • Aid security and police protection
  • Improve the flow of traffic
  • Promote business and use of public facilities at night

Local roadways do not have the same lighting requirements as large highways; however, still need to provide adequate lighting for safety to vehicles and pedestrians. Roadways are also implementing bike lanes to cater to the increase of bike usage and sidewalks for pedestrians. This requires an increase in the need for lighting for additional safety concerns of not just cars on the roadways anymore.

LED_Solar_Road_Lights

Since electrical infrastructure was not always put in place when a road was installed, solar powered road lights provide the necessary lighting without having to dig up the roads or damaging the surrounding area. These self-contained light systems are perfect for older roads as well as new road installations and cut down on installation, unsightly overhead wiring and provide immediate payback since the power is 100% free for the life of the system.

Finally, with the popularity of LED fixtures, you are not stuck with the same old Cobrahead roadway fixtures. You can utilize architectural fixtures on roadways that can produce the same lighting levels as the old style light fixtures and fit within the design of the area.

With the expansion of lighting styles and the combination of green solar power, solar LED road lights are a great way to use green power and provide lighting to just about any roadway.

Amazing Changes Happening Now for Sustainable Living: Renewable Energy

Posted by SEPCO

7/31/14 9:30 AM

Renewable-Energy

Renewable energy has been booming, especially in the last couple years. Renewable energy resources have been around for a long time; however, their popularity has increased with the ongoing movement towards trying to slow down global warming. There are many forms of renewable energy that have been used, developed and installed even as I write this. Here are the largest forms of renewable energy and a little bit about their usage today.

Solar Energy

We are a solar company so of course solar is our favorite. Solar panels provide energy during the day, from practically sun up to sun down. There is so much solar energy to be harvested, that like many statistics and memes say, so much solar energy hits the earth that if we could power the needs of the world for 25 years or more in a single day of sun. The only problem with that is creating enough solar panels to harvest all that energy and then storing the power so it can be accessed after the sun goes down; however, there are people working on energy storage as we speak. Solar energy can also be used for other applications such as water heating or heating a building / home.

Wind Energy

Wind energy can provide a ton of energy day and night as long as the wind is moving. Today’s wind power is generated by a windmill turning a turbine that generates power to feed electricity to power lines; however, wind power has been used in the past for grinding grain and pumping water. Wind farms can be installed in a large open area or offshore and provide a lot of power to nearby areas. Storage of this power is still being developed, just like solar power; however, seems to be a more popular approach to large scale power generation. New developments in wind power are being made to harness wind power when there is little wind and windmills that protect wildlife from harm.

Geothermal Energy

Geothermal power extracts steam from underground and uses that to power turbines to generate power. The water is extracted during this process and fed back under the Earth’s surface to generate more steam. The main drawback to this form of power generation is the steam can carry a mixture of gases that contribute to global warming, bad smells and acid rain. These gases need to be contained and not put into the atmosphere.

Hydropower & Tidal Energy

Both hydropower and tidal energy uses the natural flow of water to turn turbines to generate power. Dams have been set up on rivers and underwater windmill looking devices have been setup on shores to harness this power. Since tides are more predictable than the winds or sun, tidal power is growing in popularity as a great way to harness power; however, there is still controversy in changing the natural flow of water and disturbing natural habitats.

Every form of renewable energy has its pros and cons; however, by combining forces and utilizing each form to its capacity, we will one day be able to move towards a more sustainable world. Here in sunny south Florida, solar will always be my favorite source of energy. What is your favorite and why?

Solar Bollard Lighting for Parks and Pathways

Posted by SEPCO

7/29/14 9:30 AM

Bollards are used as along pathways and around parks to provide perimeter markings. They can range from concrete or steel posts to intricate decorative posts, all typically standing between 3’ and 5’ tall. Lighted bollards can provide additional features such as lighting the area at night to provide added visibility to pedestrians while marking the boundary of an area from a distance.

Solar powered bollard lights provide a green alternative and allow for lighted bollards to be placed in areas without disturbing the surrounding landscape. As the power is self-contained within a solar power system, these bollards can be placed just about anywhere. With separated solar power systems, the bollards can even be placed in shaded areas with the solar located nearby out in the sun. This allows for additional installation options than solar bollard lights that only have the solar panel installed on the top of the bollard.

Solar_Bollard_Lighting

There are a couple options to look for with solar bollard lighting. The first is with the light output. Reflectors are used to provide 360 degree lighting; however, shields allow for the light to be directed in a specific area. Second option is style of bollards as they come in either of those round or square shapes, a range of colors to fit in with current architectural requirements and the tops of the bollards can be customized with many different styles. Finally, is even pathway lighting required or just spot lighting for marking the area? If even lighting is required along a pathway, there will be a need to place the bollards closer together; however, most bollards can be placed about 15’ apart and provide a decent amount of light on the ground.

No matter what option you choose, utilizing solar bollard lighting can provide the needed lighting with no impact on the environment or the landscaping nearby. Solar provides a renewable source of energy to power the bollards and allows the area to be lit for safety of people in the area.

6 Questions to Ask Before Going Solar

Posted by SEPCO

7/24/14 9:30 AM

Before_Going_SolarAs with any investment, purchasing solar panels for your home is a decision that shouldn't be made lightly. You will need to consider many factors and avoid the numerous pitfalls. By hiring the right company and asking the right questions, you'll be able to benefit greatly from solar panels.

It is important to decide if having solar panels installed on your house is the right decision for your situation wants and needs. Solar panels offer many impressive benefits, but there are other factors to consider. We take a look at what questions you should ask before you make the switch, and the pitfalls to avoid.

1. Is the company and brand of solar panels you’re considering reputable?

You should ask the companies if they use a reputable brand of solar panels. If you can't find much information about the brand or manufacturer, then you shouldn't use those particular types of solar panels. The solar company you go through should have fully trained employees, with skilled technicians and installers to help you with the process.

Don’t be afraid to ask how long the company has been in the business. An established company that has served many customers with a portfolio of work and testimonials tends to be a company that you’re able to trust and relay on. Years of satisfied customers means good work and a reputable company will be more than willing to show off their good work and previous clientele.

In the solar business, there are unfortunately many people trying to sell cheaply made solar panels and rip customers off. Opting for a cheaper solution or a company that doesn’t appear reputable will only lead to inexperienced installer doing the job for you, additional and costly repairs, and a service that won’t follow up on you and the product after it’s installed.

By concentrating on quality above anything else and working with the right company, you’ll be able to determine whether solar panels is a good investment for your home and avoid costly mistakes.

2. Should you lease or buy solar panels?

Depending on your goals, there difference between purchasing your own solar panels and leasing can vary dramatically. Because every homeowner has different goals, the “right” payment option for each person can change.

Whilst the initial cost of purchasing solar panels yourself can be expensive, most homeowners prefer to do so. The ongoing savings on power bills solar panels offer ensure the initial expensive of them are paid off in 10 years, depending on the home. Cash rebates can also reduce the cost of the system by 10%-50% and with government incentives in place, tends to be the better option for most people.

For those that choose to lease solar panels, the long-term financial benefits will be less than those of purchasing. The advantage though is that the upfront costs are lower and any maintenance or repairs become responsibility of the leasing company, not you. Lease terms are generally for 20 years but some can range from 10-20. To find out what option is best for you, it’s best to speak with the solar power company about your specific situation.

3. Does the cost outweigh the benefits?

There is no point in investing in something that doesn’t serve you and so weighing up the cost and benefits is crucial. For homeowners that haven’t yet experienced the benefits of solar power firsthand, making the switch can be fairly daunting with the costs involved.

On the brightside though, (pun intended) the savings through solar power are significant – not to mention the environmental impact it has too. Over the last few years, everyone has fallen victim to the ongoing utility costs on the rise and we’re all looking for ways to cut down on how much we spend. Installing solar powers and taking advantage of the sun’s energy is one of the best ways to do this.

Government incentives and tax breaks sweeten the deal for homeowners wanting solar a little more, the system and panels add value to your home and the sustainable energy is a growing and beneficial industry. Whilst the initial cost can seem like disadvantage, solar power systems are one investment that will pay off and give years of enjoyment. Always ask your solar company to go through the individual costs with you. You can bring a copy of the last few utility bills too to determine if the cost will really outweigh the benefits in your home.

4. What is the type of panel mounting system that’ll be used?

Understanding the type of panel mounting system for your home, and the materials it’s made of will ensure you’re getting a durable system. Look for mounting systems that are made from either stainless steel or aluminium.

When solar panels are installed, the mounting system is what balances everything and holds it into place. Check with the company whether roof mounts, ground mounts or pole mounts would be best for your home and how this can impact on the system quality and price. The most common style of system mounting is on the roof and this is held together by metal brackets between the solar panels and roof to ensure the panels do not overheat.

5. Will you be able to produce enough power in your location?

The biggest advantage of solar power is that it relies on the sun for its power source, making it absolutely free. But, this would be pretty useless if your sun gets little to no sun right? Cloudy days can be an issue and locations that suffer all year round winters can be very indecisive about making the switch.

To accommodate for lack of sun, a large number of solar powers can be needed to produce greater amounts of electricity. This can require more roof space and money so it’s best to check with your company if this will affect you.  If you’re unsure, ask a reputable solar power company. Most companies will come to your home and conduct a site examination, including shade analysis which helps to determine whether solar is the best solution for you.

6. How long will the solar panels last for?

No homeowner wants to fork out money for an investment that won’t last the distance. This is why choosing a company that is reputable and trustworthy, and that uses quality a product is of the upmost importance. 

The lifespan of solar panels depends on several factors including the quality of the materials, and the specific manufacturer. Look for products that come with a long warranty, and this shows the manufactures commit and belief in the product. Companies that offer only a few years warranty on their products is best to stay away from, you should be looking at least 10 years.  A durable and reliable solar panel inverter and mounting system will last the distance.

3 Types of Solar Street Light Retrofit Systems

Posted by SEPCO

7/22/14 9:30 AM

So you are purchasing a new property and the street lighting is standard electric. But maybe you are looking to be a green company, or want to reduce costs, or maybe even both. There are a couple ways you can complete a solar street light retrofit and complete both goals.

Grid Intertie Systems

Solar_Street_Light_Retrofit_Grid_Intertie

The first type of solar street light retrofit system you can install would be a grid intertied system. Installing a solar panel on the existing poles to feed the grid during the day and then utilizing the grid power at night will help offset some costs and provide a green alternative. Depending on how much power you want to generate during the day determines the size of the solar panel to install. Work with a local electrical contractor to decide what you will need and the local power company to put on a special device that tracks your power generation. Also, make sure to switch to energy efficient LED fixtures to maximize your savings.

 

Off Grid Systems

Solar_Street_Light_Retrofit_Off_Grid

Second type of solar street light retrofit would be to take the systems off grid completely by installing and off grid solar powered street light. These systems charge a battery assembly during the day to provide the power to the light at night. The solar panel assembly works as a photocell to turn the light fixture on and off and typically provides five nights autonomy. This setup is more expensive to purchase, but provides free energy for the life of the systems, typically 30 years or more, with only the batteries to replace every five to seven years.

Battery Backup Systems

Solar_Street_Light_Retrofit_Battery_Backup

Battery backup systems are the best of both worlds. With a battery backup system, you generate the power for the batteries, typically smaller battery assemblies than complete off grid systems, and feed excess power to the grid. The batteries can either run the lights for a set amount of time at night followed by grid power for the remainder of the night, or only be utilized if there is a power outage in the area; a great idea for areas without reliable grid energy. This setup can also work with a larger battery backup and a trickle charger to provide multiple day storage like off grid systems but only be activated in times of grid outages.

There you have it. There are pros and cons to each type of system which we will cover next time. What type of solar street light retrofit do you prefer?

Amazing Changes Happening Now for Sustainable Living: Tiny House

Posted by SEPCO

7/17/14 9:30 AM

Tiny-HomeHomes have become larger and more spacious as time progresses; however, there is a new movement away from those expensive and inefficient homes towards tiny houses. This is great for single people or small families that want to utilize every inch of their home and have more freedom than we’ve had in years. Instead of spending $450k, more and more people are opting to spend $30k or less to build a tiny house that they can even pick up and move wherever life takes them.

Tiny homes are on a huge up rise. These homes range from under 100 sq ft to around 350 sq ft. It is amazing what you can do when you slim down all your “stuff” to your most basic needs, compact your requirements to fit into such a small place, and then build the most functional, multipurpose spaces you could even imagine. There are many benefits to a tiny house including environmental friendliness, easier to clean and cheaper to heat and cool.

Tiny homes can be powered by traditional grid by plugging in to a power outlet, or be completely off grid by installing solar power. Since these homes are so efficient, they do not require a lot of power and only need a 1k solar system or less to completely power the requirements of the home. This combined with some propane or other form of fuel for heating and cooking is about the only costs associated with living in a tiny home.

There are tons of resources available online if you are interested in building a tiny home. You can purchase complete blueprints to just inspirational ideas to create your own unique custom design. Make it as functional as possible to fit exactly what you would need and listing the most important features to the least important to get the most from the space.

If you have a family, maybe you can’t build your tiny house on the back of a trailer like some mobile tiny homes; however, you can still stay with the smaller ideals and have plenty of room for everyone. Or live in an urban area; turn your studio into a lot more by maximizing its design. There are so many options that allow you to live more efficiently in less space than ever before. You just have to look around and get your creative juices flowing to find what would fit your lifestyle best.

Solar Parking Lot Retrofit for St Augustine Beach Pier Park

Posted by SEPCO

7/15/14 9:30 AM

St-Augustine-3

In January of 2012 the City of St Augustine Beach issued plans for the re-lighting of the Pier Park parking lot. The project was officially called “City of St Augustine Beach FL Pier Park lighting retrofit” for the parking lot. The City had just recently completed the construction of a community pavilion and a new sea / beach walkway that ran between the parking lot and beach. The previous use for the area was just a parking lot for access to the pier. With the addition of the pavilion and walkway, with the pier, the area now has a park setting where families can enjoy the beach and picnic in the pavilion. The City also now uses the area for community events, such as arts shows, small outdoor concerts and food events.

St-Augustine-4

SEPCO worked together with WFLI in Jacksonville to complete the lighting design for the City of St Augustine Beach. The existing lighting consisted of randomly placed 20ft wood poles that had 100 watt high pressure sodium cobra-head style lighting fixtures mounted to them. The new lighting design approach was to use full cut-off LED fixtures of a contemporary style to compliment the pavilion and new landscaping with the following design considerations:

  •          Appropriate pole and luminaire mounting heights.
  •          Pole shape that allowed for various mounting conditions.
  •          Height of solar panels.
  •          Height of adjacent palm trees.
  •          Light source color for general parking area and turtle friendly areas.
  •          Orientation of site on north-south axis.
  •          Luminaire  requirements of having AC and DC drivers.

The height of the new palm trees was determined to be approximately 22 to 24 feet. Our design intent was to have the height of the solar panels be just above the height of the palm trees to ensure sunlight was not blocked. The six poles that had the solar arrays mounted on top of them were 5ft higher than the other AC powered poles. The mounting height of the luminaires was to be 15ft for all fixtures. A round tapered concrete pole was selected for is durability and appearance. This shape pole also allowed for proper southward facing solar panels regardless of which direction the luminaire faced.

St-Augustine-5

The overall project requirements called for 38 LED fixtures, 6 of which were the amber LED.  Along the sea walkway, the lighting there was to utilize the same LED fixture but using amber LED’s to comply with the turtle friendly lighting requirements. The light levels were designed to IESNA recommendations of 1.0fc average. The LED fixture selected used 73 watts of power. The LED driver used in the fixture was standard 0-10 volt dimming. A 5K color temperature with CRI of 80 was used for the parking area and a 2K color 580nm amber LED used for the sea walk area.

The City had applied to the Department of Energy for a grant to utilize solar power for a portion of this project. They were awarded a grant which allowed them to have 6 of the 38 LED fixtures powered by solar array panels. The 6 fixtures selected for solar power were the ones in the middle of the parking lot as they were the first to be seen upon entry to the parking lot. The project shows the Cities desire to promote “green” initiatives and integrate solar powered lighting as often as possible.

St-Augustine-6

In addition to the use of LED lighting, part of the project scope was to use a lighting control system that allowed automatic control of the light levels for the standard AC wired fixtures.The AC light fixtures, due to their use of the grid power, dim to 50% intensity part of the night to reduce the standard electrical power consumption. The off grid solar lights utilize enough energy from the solar to provide 100% intensity all night without using any energy from the grid.
