To help you find the perfect lighting for your backyard space, we've rounded up the best solar outdoor string lights available in 2021. Plus, to ensure you get a set of solar string lights that fits your needs, we're highlighting what to look for when shopping for outdoor solar string lights. 

What to Look for in Solar Outdoor String Lights

When shopping for solar string lights, there are a few key factors you'll need to consider:

Solar-Powered

If you don't have outdoor outlets on your deck, patio, or balcony, you can still enjoy outdoor lighting with solar-powered string lights. Unlike plug-in and battery-powered strands, solar-powered outdoor string lights are incredibly energy-efficient (won't affect your electricity bill), eco-friendly, and easy-to-use. No tangled power cords or expensive batteries are required! 

As the name suggests, solar string lights harness their power source from a small solar panel at one end of the strand with a number of lights attached. During the day, the solar panel converts sunlight into a power source that charges a battery through a rechargeable battery or converter. Once the sun goes down, the battery lights up the strand without needing to be plugged in. Typically, solar-powered lights require 4-6 hours of sunlight to hold enough charge for 4-8 hours of use, depending on the strand. 

The only downside of solar energy string lights is their dependence on the sun as a power source. Without enough sunlight during the day, they won't harness enough solar power sources to sufficiently light your space at night. If you live in a cloudy climate, you may have difficulty adequately charging your strand. Be sure to place the solar panel in an area that receives maximum sunlight and doesn't receive extended periods of shade. 

Bulb Type & Wattage

While outdoor string lights come in a number of lights and a variety of bulb types, it's best to stick to LED bulbs. LED bulbs have the longest life span and are the most energy-efficient type of bulb. For safety reasons, it's also important to double-check that the bulbs are weatherproof and shatter-resistant. 

You'll also need to determine what wattage you need. While higher wattages offer stronger light, they'll use up the battery's charge faster than softer lighting options. In general, 80 watts or lower is suitable for outdoor lighting, while 40 watts and lower are ideal for led lights or lighting pathways. 

Strand Length

When choosing a set of string lights, you'll need to consider how long you want the strand to be. Too long, and you'll have an overly-lit space and tangled cords. Too short, and you'll need to purchase more than one set of lights to light the area adequately. The easiest way to avoid the hassle is to measure your space to know exactly what length to look for. 

Added Lighting Effects 

These days, many LED string lights come with additional lighting effects that change your outdoor space's mood. In addition to a steady glow, many have dimmers, fairy lights, strobe light settings, soft white light, and twinkling effects. Some even offer color-changing settings perfect for lively outdoor parties and kids' bedrooms. 

Durable Design

After taking the time and effort to hang your string lights overhead carefully, you want to be sure they last for many nights to come. When shopping for string lights, you'll notice there are both indoor and outdoor varieties. Be sure to double-check that the set is suitable for outdoor spaces and can withstand year-round use in any weather.
