The 10 Best Solar String Lights (2024)

Treehugger Tested & Approved

Our testers loved the look and feel of these durable lights from Brightech, and found the overall setup easy to install. The lights shine for six hours on a full solar charge and come with a two year warranty, making them our top overall choice. In our tests, we subjected these lights to freezing temperatures, water, and hit them with golf balls. Both the solar panel and the individual lights held up through it all.

The lights are powered by a solar panel, which can be positioned to get the most sun with either the included clip or ground steak. Using a sensor, the lights turn on automatically, but can also be shut off from the solar panel in case you need darkness, but this will also stop the lights from charging again in the morning. Each strand consists of 12 lights strung on a 27 foot line, with 6 feet of wire between the panel and the first bulb. There is also a 48 foot version available.

Just keep in mind that these lights just have one brightness setting.

These solar string lights are another great choice, thanks to four lighting modes and USB charging ability. Spice up any gathering with slow flash, quick flash, pulsating, or steady light modes and rest easy knowing the set is waterproof and the bulbs are shatterproof.

The lights can illuminate for up to 8 hours with a full charge (the solar panel requires a six to eight hour charge), and hold up well in different weather conditions. The warm white lights provide a cozy glow for birthday parties, wedding receptions, garden parties, and much more. This set allows you to connect 15 more bulbs if you want to illuminate a larger area.

The price point for these lights is great, without sacrificing useful features. The lights are made of a shatterproof material that’s also IP44 waterproof and can withstand hot and cold temperatures, rain, and wind. The lights can stay lit for up to 16 hours after 4 to 8 hours of solar charging, and the 180-degree adjustable panel allows you to move it around for maximum sun exposure.

These lights can also be charged via USB if there’s no light during the day. The lights have four lighting modes, and the bulbs on this strand are spaced 1 foot apart for a total of 29 feet. You also don’t have to worry about the bulbs getting too hot, as they remain cool to the touch after hours of use.

Edison bulbs create a classic and tasteful look for any setting, and this set is even more elevated thanks to warm brushed brass bases instead of the typical black plastic. The cables are commercial grade, and the solar panel is 1.5 watts, to power the lights for 6 hours on a full charge.

The 28 foot strand has 12 LED bulbs, each of which is 1.75 inches in diameter and spaced 18 inches apart. The clear bulbs have an exposed filament look, adding to the vintage feel. They’re also made with Fair Trade certified labor, and are wet UL-listed for outdoor use.

Make trees sparkle, add a twinkle to your tent while camping, or create some magic to your garden with these fairy lights from DeVida. These lights feature a 55-foot strand with 120 LED lights, plus an extra-long lead wire to position the solar panel in the sun and out of the shade.

The extra length also means you can wrap trees and still have enough room to move the solar panel into optimal sunlight. DeVida delivers a quality product that is backed behind a family-owned U.S. company that donates a portion of net proceeds to charities.

Available in multiple colors, these mini string lights come with a panel and a solar rechargeable battery. Simply stake the panel into the ground (or mount on a wall) and allow the panel to get six to eight hours of full, direct sunlight. The lights will glow for seven to eight hours, creating the perfect environment for parties or simple outdoor dinners.

The lights also feature a dual-mode button that allow you to choose to have the lights flash or shine steady. Don’t worry about wet weather, as the lights will still twinkle despite rainy conditions.

These multicolored lights create a fairytale aesthetic and add a bit of whimsy to any outdoor space. The water droplet shape also adds an element of fun and creates an Alice-in-Wonderland-meets-mad-scientist’s-lab vibe.

A built-in sensor switches the lights on at night and off during the day while charging, and the lights can shift from colorful to warm white with the touch of a button. Don’t worry about wet weather, you can leave these lights outside and they’ll be fine after a rainstorm. These are perfect for night-time swims, groovy garden parties, children’s birthday parties, and even seasonal holiday decorating.

Time travel back to your childhood with these multicolor lights that are reminiscent of vintage multicolor holiday lights and all things Lisa Frank. The lights need to charge during the day for six to eight hours, but will illuminate for more than eight hours at night. Fifty flower lights dance across a 21-foot strand, providing light that’s also waterproof and can withstand heavy rain and snow.

Two switches on the set allow lights to either flash or shine steady. Users love these lights for indoor and outdoor uses—they’re perfect for little girls’ bedrooms, dreamy gardens, and anywhere you want to add a touch of color.

Available in an array of colors, these solar lights from Supsoo help to create a magical holiday scene. Choose from warm white, green, blue, cool white, or multicolored lights that are perfect for decorating an outdoor Christmas tree, wrapping around the exterior of your house, and using throughout your holiday decor.

Eight different light modes also allow you to set the lights to twinkle, flash, fade, or steadily glow. On a full charge, the lights can shine for as long as 12 hours. The lead cable is also six feet long, allowing you to place the panel in the sunniest location for maximum charging. The set is also waterproof, so rest easy if there’s bad weather.

Our tester found that these lights are a bit harder to set up than other string light options, because the shape of the snowflakes can get tangled more easily. However, once up, the effect is so charming that they're worth the extra effort. The solar panel has a steak to secure it to a sunny spot in the ground, and the strand is 30 feet long.

The 50 snowflake lights are lit by LED bulbs, and there are eight lighting modes, including twinkling, slow fade, chasing, slow-glow, and more. There are also multi-color and star-shaped versions of these lights.

Final Verdict

Frequently Asked Questions

• How do you hang solar string lights

  You can hang outdoor string lights from trees, railing, posts, ceiling beams, and more. You’ll need to measure the distance of the space you’re planning to hang lights from to determine how many feet of lights you’ll need. If you want to drape your lights or have them wrapped around beams or hung loosely from posts, you’ll need to add to your footage.

  You can use small hooks if you’re hanging lights from beams and posts. If you’re draping lights from a railing, simply drape the lights to your liking, and secure them with twine, wire, or even zip-ties. Or you can consider purchasing gutter clips, which allow you to attach string lights to gutters or awnings without making any holes.

• Can solar string lights start a fire?

  Solar string lights harness their power from energy from the solar panels that charge the batteries. While the risk for a fire is low, it can happen, especially if your solar lights contain lithium-ion batteries. Check to make sure you know what kind of batteries your string lights contain, as cheaper materials can sometimes put off more heat and cause a fire to start in the light’s casing. Overall, it is not likely that your solar lights will catch on fire, but it can happen.

• Can you use solar string lights indoors?

  Yes. Some solar lights come with USB charging capabilities, and if that’s the case, you can definitely use that USB charging port to power the lights and use them inside. You can also place the solar panel near a bright window to gather sunlight for charging.
