How To Choose The Best Commercial Parking Lot Solar Lighting

In our automobile-centric society parking lots are almost a requirement for any business. As an owner and/or operator, safety is one of your responsibilities.

In our automobile-centric society parking lots are almost a requirement for any business. As an owner and/or operator, safety is one of your responsibilities.

We will discuss the considerations you should make when choosing the best commercial parking lot solar lighting for your business.

Commercial solar lighting is a large initial investment but will pay itself off in the long term with years of “free” energy from the sun. You can purchase an all-in-one solar lighting pole light or the panels and lights separately.

We will focus here on the simple utility of all-in-one commercial LED parking lot lights.

How To Choose The Best Solar Parking Lights

When choosing lights for your solar parking lot, there are certain things to look for. Efficiency, efficacy, lighting power density, light distribution, color qualities, light layout, and desired results should be carefully considered to achieve the best results.

You can keep it simple with all-in-one units or go all out with a solar canopy and boost it with the best solar flood lights available on the market.

 Most municipalities have requirements in place guiding the use of parking lot lights. Height, timing, brightness, and excessive light must all be controlled following these regulations.

This guide will help sort through some of these issues, hopefully, in turn, making your purchase a little easier.

Mounting Styles

LED pole light fixtures are the most common way to light a parking lot surface, but floodlights are also an option. Floodlights can be very bright and are usually mounted on walls, poles, or landscaping, allowing them to be functional and aesthetically pleasing at the same time.

The number of pole or floodlights you need will be determined by how high they are placed, how bright they are, and the area’s size being lit.

PIR Motion Sensor

A passive infrared sensor(PIR) is included on many solar parking lot lights to conserve battery life. All objects with a temperature above absolute zero emit infrared radiation from heat energy.

These sensors work by measuring this infrared light allowing the sensor to detect movement.

HID Lights

Traditionally most parking lots were lit with high-intensity discharge(HID) lights. The HID metal halide lamps commonly used consist of an arc tube(burner), outer envelope(bulb), and a starting gas.

The ballast supplies the ceramic or quartz arc tube with a voltage, which begins ionizing the gas(usually argon, mercury, and metal halide salts).

As temperature and pressure increase within the bulb, materials in the arc tube vaporize, emitting light and UV radiation. These lights are very bright but must be replaced every few years and are energy inefficient. These are not a viable solar option.

LED Lights

Light-emitting diodes(LEDs) use tiny microchips to produce visible light in the diode. This light production method is very efficient, and the “bulbs” don’t burn out like conventional light fixtures.

LEDs instead of experience lumen degradation, slowly dimming over time.

 However, this is a prolonged process, and you wouldn’t need to replace your LEDs for many years after installation. The Lighting Energy Efficiency in Parking(LEEP) organization has several case studies highlighting the energy-saving benefits of LEDs.

Luminaire

In technical terms, a luminaire is a complete lighting unit consisting of a lamp or lamps together with the parts designed to distribute the light, position and protect the lamps, and connect the lamps to the power supply.

The Federal Energy Management Program(FEMP) created a guide to be used by federal agencies when installing parking lot luminaires.

This guide is a useful resource in determining the best solutions for your parking lot lighting.

Luminaire Efficacy

A luminaires efficacy rating, LER, is measured in lumens per watt(lm/w). This rating is crucial as it will show you how much light is generated compared to the energy consumed. It is merely total light output(lumens) divided by input power(watts).

High lumen solar lights are not always the best, and you should pay attention to how well the luminaire focuses its light.

Creating A Plan

Figuring out which luminaires you want to replace, noting height, and general light information will make things easier when choosing new lights. Consider the quality and quantity of lights you may need; different facilities have different lighting requirements.

Lighting should be uniform across your entire lot as high contrast levels can obscure surveillance footage and can cause blind spots for vehicles and pedestrians. Keep this in mind as you may need to install more lights when purchasing less powerful but more efficient models.

Use lighting controls like bi-level outputs and fixed response switches to turn off specific luminaires during off-peak periods. This will conserve energy allowing you to run your solar lights longer.

Illumination Levels

The Illuminating Engineering Society of North America(IES) has recommended light levels to check out for different lighting applications. Recommended amounts are prescribed in footcandles(FC), which are the primary measurement for light falling on a surface.

Measurements can be taken with a handheld light detector. A 4:1 (bright/dark) ratio between the brightest and darkest areas is considered a suitable minimum, but a 3:1 ratio is better.

Footcandles matter more than lumens when considering parking lot lights as they tell you how much illumination the parking surface is receiving. Color temperature, measured in degrees kelvin, is also essential to consider.

Depending on what material your lot is made of, color temperature will affect how the light appears on the parking surface.

Solar And Battery Storage

Solar parking lot lights use the sun’s energy, collected by photovoltaic cells, to store electricity in a battery, which is later used for your lighting needs. Look for a solar panel and battery combination that offers a large milliampere-hour(mAh) capacity. 

Check the ratio between the solar panel and battery while looking at luminaire energy draw. Ensure the panel is sufficient to charge the battery and the battery has enough capacity to run the light for multiple hours.

Final Thoughts About Choosing A Solar Parking Lot Lighting

Choosing parking lot lighting for your business might not be the most thrilling task you must undertake as a business owner or manager, but it is nonetheless essential. Lighting provides safety and security to guests, helping deter vandals and thieves from skulking in the shadows.

I also recommend you light the vertical surfaces in your lot, which can add definition to your building’s outdoor appearance. After carefully considering several lights, I think the LEDMO 200W solar flood lamp is a great option to use in your solar-powered parking lot.

It can be mounted in almost any way you want, making it the most versatile option. The 16.5 foot connecting cable allows independent placement of the solar panel while the remote allows you to access lighting controls from a distance.

It is 10,000 lumens, which quickly makes it the brightest on the list, and should work for most business applications. The large capacity 39,000 mAh hour battery and 32W solar panel should keep the light running throughout the night, providing a safe space for your customers. 

It may be best to purchase a single light at first so you can analyze how effectively it will fulfill your needs. With lighting alone accounting for a large portion of a business’s budget, anything that can reduce cost in the long term should be considered.

Adding solar-powered lights to your parking lot may be the ticket to reduced running costs.
