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

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

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

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?

Comparing Solar Light Pole Project Cost vs System Cost

  Often in the solar lighting industry, we receive calls asking for a system to meet a need in an area where power is not feasible to bring out, but then months later, the customer tells you they

Solar Tax Incentives May Not Expire But 2019 Is The End Of 30%

The Business Energy Investment Tax Credit (ITC) is not ending, but 2019 is the end of the 30% benefit and will begin to reduce after this year. What does this mean for people looking to go solar? Act

How to Deal with Light Trespass with your Next Solar Lighting Project

  When designing a lighting solution, light trespass needs to be considered, especially when located near a neighborhood. Light pollution is another factor that should be looked at when in the design
