Best Solar String Lights

Treehugger / Chloe Jeong

Do you want to spruce up your backyard oasis, patio, or even apartment balcony? String lights can add a festive twinkle to your space that’s perfect for romantic alfresco dinners in the summer, a relaxing outdoor happy hour, or holiday decorations. However, traditional string lights require being plugged in, which increases your electric bill and can contribute to planet-heating pollution unless your home is already powered by renewables. 

Solar string lights run on energy from the sun and are handy if you don’t have an outdoor outlet available. Just make sure the charging panel is in a location that gets plenty of sun, and as darkness creeps in, watch as your outdoor space comes to life with light. 

Here are the best solar string lights:

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.

Best for Holidays Runner Up: Huacenmy Outdoor Solar Snowflake String Lights

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 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, and more.

Final Verdict

The MagicPro string lights (view at Amazon) offer a classic look, plus additional lighting modes and the ability to charge via USB, which gives them a leg up from many traditional, white solar lights.

If you want something more festive, consider the Lemontec water droplet lights (view at Amazon), with their fun look and multicolored lights.

What to Look for in Solar String Lights

Size and Shape

Different types of string lights serve different purposes. For example, Edison bulbs offer a soft, glowing appearance that are great for romantic settings like patios and outdoor dining spaces. Rope lights, for example, serve a different purpose in that they’re often used more to light pathways like docks, fences, and pathways. When choosing your solar lights, be sure to consider what you’ll be using them for and the space you’re putting them in.

Brightness

You'll want to think about how bulbs are that you’re buying will illuminate your space. Many times, solar lights won’t put out quite as much light as traditionally powered lights, but many users are okay with that, as they’re trying to create an ambiance of soft light or add to a romantic setting. Although some products don't list the number of lumens produced by string lights, a higher number of lumens indicated a brighter bulb. If you really want to light up a space using string lights, you might want to consider getting additional strands.

Weather

Be sure that the outdoor string lights you purchase are weather-resistant, since they’ll be exposed to elements like rain, cold, and heat.

FAQs

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.

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.
