How Much Does A Solar Panel Light Cost?

Solar panel lights are self-contained lighting units that don’t require wiring or connection to an electrical grid. They absorb sunlight during the day to charge their internal battery, then turn on automatically at night to provide lighting. They come in a range of sizes and styles for anything from pathway or security lighting to stand-alone fixtures for patio and porch illumination. Their key benefits include:

  • No wiring required – They can be installed anywhere since they don’t need to connect to your home’s electrical system.
  • Portable – Smaller solar lights are fully portable so you can move them wherever you need light.
  • solar lights are portable and can be placed anywhere outside that needs illumination.

  • Affordable – No installation cost and free renewable energy from the sun after the initial purchase.
  • Eco-friendly – Solar lights don’t require fossil fuels and have zero emissions.
  • Low maintenance – Most don’t require any maintenance beyond an occasional cleaning of the solar panel.

What Are Solar Panel Lights?

Solar panel lights are portable lighting devices powered by solar energy. They consist of a solar panel, battery, LED lights, and plastic casing. The solar panel absorbs sunlight during the day and charges the battery. At night, the charged battery powers the LED lights to provide illumination. These lights are self-contained units that do not need to be plugged into an electrical outlet. Their portability and independence from the electrical grid make them useful for outdoor activities like camping, hiking, and emergency preparedness. They can also be used indoors to provide supplemental lighting. Solar panel lights come in a variety of shapes, sizes, and lighting strengths to suit different needs.

Cost Components

The main components that make up the cost of a solar panel light include:

Solar Panel

The solar panel is often the most expensive part of a solar light. On average, a small 5V 1W solar panel sufficient for a solar light costs $15-30. Larger, higher efficiency panels can cost $50 or more.

the solar panel converts sunlight into electricity to charge the battery.


Rechargeable lithium-ion batteries suitable for solar lights range from $5-15 on average. Lower capacity batteries are cheaper while higher capacity batteries cost more.

LED Light

LED bulbs and fixtures optimized for solar use are relatively inexpensive, typically $5-10 for lights bright enough for path, porch, or security lighting.


The outer plastic casing, housing, and mounts for a solar light often add $5-20 to the overall cost depending on durability and weatherproofing features.

Solar Panel Cost

The solar panel is the largest cost component of a solar panel light. Solar panels are made up of photovoltaic cells that convert sunlight into electricity. The most common type of photovoltaic cell used is the silicon cell. The amount of electricity a solar panel can generate depends on the size, efficiency, and wattage of the solar panel.

Larger solar panels with higher wattage ratings are able to produce more electricity, but they also cost more. A small 5-watt solar panel may cost $20, while a larger 20-watt panel may cost $60 or more. Standard panels for solar lights range from about 5 to 30 watts.

Higher efficiency solar panels with advanced silicon cell technology are more expensive but can generate more electricity from the same amount of sunlight. Low-cost panels may only have 5-10% efficiency, while premium panels convert over 20% of sunlight into electricity.

When determining solar panel cost, it’s important to consider the size and wattage you need for your application. Large high-wattage panels will be able to charge batteries faster and power larger lights, but they come at a premium cost. Smaller, lower-wattage panels are more affordable, but may charge slower.

Battery Cost

The battery is one of the most significant contributors to the overall cost of a solar panel light. Most solar lights use either lithium-ion or lead-acid batteries to store energy from the solar panel.

Lithium-ion batteries are more expensive initially, but have a longer lifespan and better performance in cold weather. They come in various capacities, typically ranging from 1,000mAh to 4,000mAh for small solar lights. Expect to pay $15-$30 for a decent lithium-ion battery.

lithium-ion batteries have a longer lifespan and perform better than lead-acid.

Lead-acid batteries are cheaper upfront, typically $5-$15, but have a shorter lifespan of around 1-2 years. They’re also bulkier and less efficient in cold temperatures. Lead-acid batteries for solar lights commonly range from 800mAh to 2,000mAh.

In general, a higher battery capacity means longer illumination at night, but also a higher cost. Choosing the right balance depends on your specific needs and budget.

LED Light Cost

LED lights are usually the biggest expense for solar panel lights. The cost varies significantly based on the number and brightness of the LED bulbs used.

Typically, solar panel lights will have between 1 to over 100 LEDs. The more LEDs, the brighter the light and the higher the cost. Here are some examples:

  • 1-3 LED solar lights – These provide a soft glow and ambiance. Each LED may cost $1-5.
  • 10-20 LED solar lights – These are bright enough for accent lighting. Each LED may cost $2-10.
  • 50+ LED solar lights – Very bright floodlights. Massive lighting. Each LED may cost $5-20.

So a solar light with 3 dim LEDs may cost $3-15 just for the lights. But one with 100 bright LEDs could cost $500-2000 for the LEDs alone. The number, brightness, and quality of the LEDs has a major impact on the overall solar panel light cost.

the number and brightness of leds impacts the overall cost.

Casing Cost

The casing holds all the components of a solar light together and protects them from the elements. There are two main options for solar light casings – plastic or metal.

Plastic casings are less expensive, lighter weight, and can be molded into various shapes. The downside is they provide less durability than metal and may degrade over time in outdoor conditions. Expect to pay $10-20 for a decent plastic solar light casing.

Metal casings are more durable, rust-resistant and longer-lasting but also cost more. Aluminum and stainless steel are common options. Metal casings range from $20-40 depending on the material and quality.

Both plastic and metal casings should offer an IP waterproof rating (a standard measure of water resistance). Look for a rating of IP65 or higher which indicates complete protection from dust and resistance to low pressure water jets. The casing cost rises with higher IP ratings.

Overall, a plastic casing helps keep costs down while a metal casing comes with a higher price tag but also greater longevity.

Additional Features Cost

metal casings are more durable but plastic is cheaper.

Beyond the solar panel, battery, and LED lights, there are some additional features that can raise the cost of a solar panel light. Some of the most common extra features include:

  • Light settings – Many solar lights allow you to adjust the brightness or change the color of the light. Adding settings like low, medium, and high brightness or different color light modes will add $5-15 to the overall cost.
  • Motion sensor – Some solar lights have a motion sensor that automatically turns the light on when it detects movement. This sensor can add about $10-20 to the cost.
  • Phone charging – Higher-end solar lights often include a USB port so you can charge your phone or other small devices. Expect this feature to add $15-30 to the total cost.
  • Hanging hooks – For solar string lights you hang outside, hooks and mounting hardware can add $5-10 to the overall cost.
  • Remote control – A handful of solar lights include a remote control to turn the light on/off from a distance. This can increase the cost by $10-20.

While they may not be essential, these extra features add functionality and convenience that some customers are willing to pay for. The more features included, the higher the solar panel light will cost.

Total Cost Range

The total cost of a solar panel light can range quite a bit based on the quality and features. Here’s a look at the cost range:


At the low end, a basic solar light may cost $10-$30. This would include a small solar panel, battery, and LED light. The casing would be made of cheaper plastic. These affordable solar lights are good for basic outdoor lighting needs.


A mid-range solar light may cost $30-$75. These offer larger solar panels, improved batteries, and brighter LED bulbs. The casing is higher quality. Mid-range solar lights provide better performance and durability.


At the high end, premium solar lights cost $75-$200+. These utilize the highest efficiency solar panels and lithium batteries for maximum solar charging and brightness. The LED lights are very bright and the casing is durable aluminum or stainless steel. High-end solar lights are ideal for security lighting and other demanding needs.

As you can see, solar panel lights come in a wide range of prices based on the quality and performance. Carefully consider your lighting needs and budget to choose the right option.


In summary, the total cost of a solar panel light can range anywhere from $10 to $100 or more, with the solar panel itself accounting for the largest portion of the expense. The final cost depends on factors like the panel wattage, battery capacity, lighting brightness, and extra features. Basic low-wattage lights for outdoor use start around $10-20, while larger high-powered indoor ceiling lights can cost $80-100 or more.

When deciding how much to spend, consider how much illumination and battery backup you need. Smaller low-wattage panel lights are appropriate for accent lighting, outdoor paths and spotlights. Larger solar panels with bigger batteries provide brighter light for several hours indoors and are a good clean energy option, though more costly. Carefully evaluate your lighting needs and budget to choose the best solar panel light at the right price point.
