 Save Big: Calculating the Energy Savings of Solar Dock Lights


Having a dock is amazing, but illuminating it at night can be costly using conventional energy-consuming lights. Solar dock lights are an excellent substitute because they depend on the sun for their power; hence they are dependable and environmentally friendly while saving you some cash on your electric bill.

However, what is the amount of money saved by solar lights? Through this research article, we shall assist you in determining the precise quantity of energy (and dollars) saved by switching to solar-powered dock lighting systems.

Why Calculate Energy Savings? Highlighting the Advantages

Solar Dock Lights

But before we get into the math, let’s talk about why it’s important to know about energy savings:

  • Financial Clarity: Figuring out how much you could save will help you understand what kind of return on investment (ROI) you can expect from your solar dock lights, which in turn, allow you to make better financial decisions.
  • Environmental Impact: Solar power is a clean and renewable source of energy. By determining the amount of energy saved using this lighting system, one can measure one’s contribution to making our planet greener.
  • Informed Decision-Making: When people know the financial and environmental benefits of different types of solar dock lights, they can choose those that best meet their needs and align with their values.

Factors that Influence Energy Savings A Illumination on Variables

The savings in energy you’ll see by together solar dock lighting depend upon several key elements. The Alternatives: What are You In Comparison to?  The main factor to consider is the kind of light that you’re changing. This is a good example:

  • Incandescent Bulbs: These bulbs use much power, making them the least efficient choice.
  • Halogen Bulbs: Slightly more efficient than incandescent bulbs, but still use significant electricity.
  • CFL Bulbs: Lights with compact fluorescent are much more efficient than incandescent or halogen; however, they will last longer.
  • Led Bulbs: light-emitting diodes are the most efficient option and consume considerably less energy than other bulbs.

2. Hours of operation: How Long Do You Need Your Lights to Stay On?  The longer the dock lights remain lit each evening, the greater energy they use up. Be aware of these things:

  • Seasonal Variations: Do you utilize your dock throughout the year or just a few times of the year?
  • Personal Preferences: would you like to witness your dock to be brightly lit in the evening or just in peak times?

3. Wattage: Measurement of Energy consumption.  
Wattage refers to the amount of electricity a light or a bulb requires in an hour. Solar dock lights usually utilize LED bulbs with low watts, which results in huge energy savings.4Solar Panel Efficiency: The effectiveness of a solar panel directly impacts the quantity of energy stored within the battery. This affects the length of time your lights can run without the need for grid energy.

5. Battery Capacity: The storage of Sunshine

A larger battery capacity enables the solar dock lights to run for longer durations with a single charge and reduces your dependence on grid electricity.

Savings Calculation: Let’s do the math!

Solar Dock Lights

We’ll break down the calculation process into basic steps:

1. Calculate Your Baseline Energy Consumption:

  • Find the current lighting on your dock (or the wattage of the lights you’re looking to replace).
  • Add the wattage multiplied by the typical duration of the time that lighting is on during the day.
  • Multiply this amount by the number of days or months that you are using the dock lighting.
  • Divide the results by 1000 to convert Watt-hours into Kilowatt-hours (kWh).


Baseline Consumption (kWh) = (Wattage x Hours per Day x Days per Month) / 1000

Example: Let’s assume you have four 100-watt incandescent dock lights that are on for 6 hours per night, 30 days a month:

Baseline Consumption = (100 watts x 4 lights x 6 hours x 30 days) / 1000 = 72 kWh per month

2. Calculate the Energy Consumption of Solar Dock Lights:

  • Determine the wattage of the LED bulbs used in the solar dock lights you’re considering.
  • Since solar dock lights are powered by the sun, assume minimal reliance on grid power (e.g., 10% of the time).
  • Multiply the LED wattage by the assumed grid-powered daily hours (e.g., 0.6 hours for 10% of 6 hours).
  • Multiply this number by the number of days per month you use your dock lights.
  • Divide the result by 1000 to convert watt-hours to kilowatt-hours (kWh).


Solar Consumption (kWh) = (LED Wattage x Assumed Grid-Powered Hours per Day x Days per Month) / 1000

Example: Let’s assume you’re considering solar dock lights with 10-watt LED bulbs:

Solar Consumption = (10 watts x 4 lights x 0.6 hours x 30 days) / 1000 = 0.72 kWh per month

3. Calculate Your Energy Savings:

  • Subtract the solar dock lights’ energy consumption from your baseline energy consumption.


Energy Savings (kWh) = Baseline Consumption - Solar Consumption


Energy Savings = 72 kWh - 0.72 kWh = 71.28 kWh per month

4. Calculate Your Cost Savings:

  • Multiply your energy savings (kWh) by your local electricity rate (cents per kWh).


Cost Savings = Energy Savings (kWh) x Electricity Rate (cents per kWh)

Example: Let’s assume your electricity rate is $0.15 per kWh:

Cost Savings = 71.28 kWh x $0.15/kWh = $10.69 per month

In this example, switching to solar dock lights could save you over $10 per month or $128 per year.

Beyond the Numbers: More Benefits of Solar Dock Lights

Apart from being cost-effective and energy-saving, solar dock lights have other advantages too:

  • Eco-friendly: This means that you are contributing to a cleaner and healthier earth by reducing the use of fossil fuels.
  • Reduced Carbon Footprint: Solar power is carbon neutral, which implies that it does not contribute to global warming or climate change, hence minimizing environmental pollution.
  • Low Maintenance:  You will not spend much time or effort maintaining these lights since they need little attention.
  • Safety Improvement: Well-illuminated docks enhance visibility, making navigation safer during dark hours.
  • Increased Property Value: Solar-powered amenities can make your property more valuable and attractive.

Making The Switch: What are your options?

When you are deciding on solar dock lights, take into account these aspects:

  • durability and weather Resistance: Look for lights made to withstand the tough marine conditions.
  • Brightness and Coverage: Pick lighting that helps provide sufficient lighting for the size of your dock and arrangement.
  • Capacity of Battery and Solar Panel Performance: Always choose lights with high-capacity batteries and efficient solar panels to achieve better performance.
  • Aesthetics and Features: To complement your dock, consider features like motion sensors and dimming, as well as design and aesthetics.
