There are many different factors to consider when putting together a solar street light proposal. Not many people know all the considerations required, but here is a list of a few little-known factors that can make the specification process a little less stressful.
1. Traffic Hours
What are the main traffic hours on the street? Does the traffic become minimal after a certain time? When does the traffic pick up again? If there is little to no traffic between 1 am and 5 am, there are no safety concerns with lowering the wattage of the fixture to conserve energy; therefore, reducing the size of the solar required to run the fixture all night.
Is the main road covered by trees? Solar requires direct sunlight to charge the batteries that operate the fixture at night. By making sure the lights are not going to be installed under shade will prevent future operation issues. If the lights need to be mounted under a tree, the solar can be remotely mounted in a sunny area to keep the light pattern even.
3. Lighting Level Requirements
What are the lighting requirements for the street? Is this a two or four lane street? Depending on the lighting requirements and width of the street can determine how many solar street lights are provided in the proposal. With aimed optics, a wider pattern is available in most applications and can reduce the overall number of fixtures needed. This can affect the overall project proposal cost including both the material and the installation.
4. Mounting Requirements
Are there specified mounting requirements such as wind loading? Making sure your solar is mounted to the appropriate pole can change many aspects of the proposal. Wind loading ratings are used in a variety of areas, especially those prone to large storms or hurricanes. Having a high wind load rating will provide a lasting light no matter what Mother Nature throws at you.
With all the parts of a solar street light proposal, making sure all aspects are covered will make sure you get the most accurate proposal available. Talk to your solar lighting professional and don’t be afraid to ask questions.
