What You’ll Need
Tools & Materials:
- Solar-powered outdoor string light set with panel, mounting hardware, and instructions
- Tape measure
- Pencil or removable marker
- Outdoor-rated hooks, screw eyes, or cable clips suited to the supports
- Drill and appropriate bit, if installing screw-in hardware
- Ladder rated for your weight and work height, if needed
- Outdoor extension cable or approved mounting pole for the solar panel, if required by the product
Knowledge:
- Basic measuring and marking
- Ability to use a drill safely, if drilling is needed
- Basic ladder safety
Check the product instructions for mounting, charging, controls, and weather limits before installation. Confirm the strand and panel are rated for outdoor use. Do not attach lights to power lines, gutters that cannot support a load, or tree branches that may move heavily in wind. If drilling into a wall, check for hidden wiring and pipes, and use fixings suited to the wall material. Work in dry conditions and ask another person to steady the ladder.
Brightown 108 ft Solar String Lights with Remote and USB Charging
The Brightown 108 ft earns the top spot because it brings together the broadest coverage, dense bulb spacing, and the strongest stated runtime in this comparison. Its 50 warm-white G40 LEDs are set two feet apart, so the strand provides more points of light than the 31-bulb Brightown 100 ft across a similar stretch. That difference may suit buyers who want a more continuous decorative glow rather than a sparse outline around a patio or yard.It is also the most adaptable option when sunshine is unpredictable. Along with its solar panel, this strand supports USB-C charging, and the remote can adjust brightness through four levels, choose among three modes, and set a timer. The stated runtime of up to 36+ hours is notably longer than the 100-foot model’s up to 26 hours, though actual solar performance still depends on available sunlight. Its IP65 rating, shatterproof bulbs, spare bulbs, and included mounting accessories add practical value for outdoor installation.The tradeoff is that the strand cannot connect to additional strands, so 108 feet is the limit for one continuous run. It is also a lot of light for a compact balcony, where the more manageable Brightech set may be a better match. We would choose this Brightown when coverage and control are priorities, not when we need a modular system or a small, simple accent.
Pros:
- 108-foot length with 50 bulbs spaced two feet apart
- Solar and USB-C charging provide more flexibility than solar-only designs
- Remote offers four brightness settings, three modes, and timer options
- IP65 rating, shatterproof bulbs, two spares, and mounting accessories
Cons:
- Cannot connect additional strands, limiting expansion beyond the supplied run
- Solar charging performance depends on sunlight, so cloudy or shaded locations may need USB-C charging
Best for: Buyers lighting a long patio, pergola, or yard who want dense bulb spacing, remote controls, and USB-C charging as a backup to solar.
Not ideal for: Anyone who needs to connect multiple strands into a longer continuous run, or who has only a small area to illuminate.
Bottom line: For a large outdoor area, we favor the Brightown 108 ft for its combination of close bulb spacing, USB-C backup, and the longest stated runtime here.

Brightown 100 ft Solar String Lights with 31+2 Shatterproof LED Bulbs
The Brightown 100 ft is a close alternative to our top pick, but it uses fewer bulbs along a nearly comparable length. Its 31 LEDs create a more open arrangement than the 108-foot model’s 50 bulbs, which may suit buyers who want a more spaced-out decorative outline instead of a fuller line of light. The specified 2700K warm-white color gives buyers a clear reference for the look, while the shatterproof PET bulbs and IP65 rating support outdoor use.Like the longer Brightown, this set has both solar and USB-C charging, remote control, four brightness settings, three lighting modes, and timers. Its stated runtime reaches up to 26 hours, making it a capable option for extended use, but it trails the 108-foot model’s 36+ hours. Solar charging is also specified at 7–8 hours, compared with 4–5 hours for USB-C, so the alternate charging route may matter if the panel cannot receive strong daylight. The product also lists wind resistance up to 50 MPH, a useful detail for exposed installations, though placement and mounting remain important.A built-in light sensor can complicate daytime operation: the product description notes that the panel may need to be covered to use the lights during the day. Compared with the 108-foot Brightown, this model gives up bulb density and some runtime; compared with Brightech, it brings far more length, remote features, and USB-C charging. It makes sense for buyers who want long coverage and a warm color specification but do not need the most bulbs per foot.
Pros:
- 100-foot length with warm 2700K light
- Solar and USB-C charging, plus remote control
- Four brightness levels, three modes, and timer options
- IP65 rating, shatterproof bulbs, and stated wind resistance up to 50 MPH
Cons:
- 31 bulbs across 100 feet provide less dense coverage than the 108-foot Brightown
- Solar charging takes a stated 7–8 hours, and runtime is shorter than the top pick
- The light sensor may need covering for daytime use
Best for: Buyers who want a long outdoor run, a specified 2700K glow, remote dimming, and a choice of solar or USB-C charging.
Not ideal for: People who want denser bulb coverage or the longest stated runtime, or who need uncomplicated daytime operation without managing the light sensor.
Bottom line: We recommend this Brightown when warm color and flexible controls matter more than maximum bulb density or the longest runtime.
“We recommend this Brightown when warm color and flexible controls matter more than maximum bulb density or the longest runtime.”
Brightech Ambience Pro Solar-Powered Outdoor String Lights, 27 ft, 12 Shatterproof LED Bulbs
The Brightech Ambience Pro serves a different purpose from the two Brightown strands: at 27 feet with 12 S14 bulbs, it is designed for a smaller seating area or a short decorative run, not broad yard coverage. Its detachable solar panel can be placed with an included stake or clip, which gives buyers more freedom to position the panel in a sunny spot even when the lights themselves hang in partial shade. That setup flexibility is especially relevant for a compact solar-only option.Its soft white 3000K light and shatterproof bulbs make it a straightforward choice for patios and outdoor gatherings, and the stated wind resistance is up to 50 mph. The two-year limited warranty also distinguishes it from the Brightown products in the supplied details. However, runtime is only about 5–6 hours on a full charge. That is far below either Brightown model’s stated maximum and may not cover a long evening, particularly when the panel does not receive direct sunlight. Its IPX4 weather-resistance specification is also less robust on paper than the IP65 ratings of both Brightown options.We would select Brightech over the longer strands when the area is modest and a smaller solar-only setup is the goal. It is less suitable for buyers who want remote dimming, timers, multiple lighting modes, or USB-C charging; those controls and backup charging are found on both Brightown models. For larger spaces or longer nights, the 100- or 108-foot Brightown is the more practical fit.
Pros:
- Compact 27-foot strand suited to smaller outdoor areas
- Detachable solar panel includes stake and clip for flexible placement
- Shatterproof S14 LEDs with soft white 3000K light
- Includes a two-year limited warranty
Cons:
- Solar-only charging offers no USB-C backup
- Stated 5–6-hour runtime is much shorter than either Brightown option
- IPX4 rating is less protective on paper than the Brightown models’ IP65 ratings
Best for: Buyers decorating a small patio, balcony, or seating nook who prefer a compact solar-only strand and a detachable panel that can be positioned separately.
Not ideal for: Anyone lighting a large space, needing USB-C backup or remote controls, or expecting the lights to stay on well into a long evening.
Bottom line: For a small space where compact solar simplicity matters more than runtime and control, the Brightech is the better fit than either long Brightown strand.

Before You Start
Open the package and identify the panel, light strand, stakes or mounting bracket, connecting cable, and any included clips. Keep the lights switched off while arranging them, unless the manufacturer directs otherwise. Choose the final layout before drilling: solar lights depend on daylight, so a shaded panel can leave the strand dim or unlit. Make sure the panel cable can reach its mounting point without being stretched, pinched, or placed where people will trip over it.
Solar lights may have a pull tab, removable battery spacer, or separate power switch. Follow the included setup instructions, since controls differ by model. Allow the panel to charge in direct sunlight for the period specified by the manufacturer; a full day is a useful first test when no charging time is given.
Step-by-Step Instructions
Step 1: Choose the light route and panel location
Measure the area where the lights will hang, then map a route between stable supports such as a pergola beam, fence posts, or a house wall. Leave enough slack for the strand to form the curve you want, while keeping it clear of doors, walkways, grills, and sharp edges. Pick a panel location that receives several hours of direct sunlight during the day and is easy to reach for cleaning or seasonal removal. Check that trees, rooflines, and nearby buildings will not shade it for much of the day.
Tip: A sunny panel location may be separate from the strand route. Use only the extension lead or panel placement options approved for your model.
Check: You have a measured route with secure attachment points, and the panel location has a clear view of the sun for much of the day.
Step 2: Test the lights and prepare the panel
Lay the strand out on the ground without pulling it tight. Check the bulbs, cable, connectors, and panel for cracks or other damage. Remove any battery tab or packaging spacer, connect the panel if it is separate, and set the switch to the position specified for charging or operation. Use the product’s test button or cover the panel to check whether the lights respond, if the instructions describe that test. Do not leave a damaged set installed.
Tip: Some models only turn on in darkness. If the lights do not respond in daylight, cover the panel or wait until dark rather than assuming the strand is faulty.
Check: The cable and bulbs appear intact, the panel is connected, and you know how to switch the set on or test its light sensor.
Step 3: Mark and install the strand supports
Mark the attachment points along your chosen route, spacing them according to the strand length and the support material. Install outdoor-rated hooks, screw eyes, or clips into solid supports, following their directions. For wood, use suitable pilot holes when needed; for masonry, use anchors designed for that surface. Do not rely on adhesive hooks unless they are rated for outdoor conditions and the strand’s weight. Keep fixings away from the strand’s bulbs and leave room for the cable to hang without rubbing on a sharp corner.
Tip: Use a ladder on firm, level ground. Keep three points of contact and do not lean sideways to reach a fixing; move the ladder instead.
Check: Each fixing is secure and aligned with the planned route, with no sharp edge likely to cut or chafe the cable.
Step 4: Hang the light strand loosely
Start at one end and place the strand into the installed hooks or clips, working toward the other end. Support the cable at several points so its weight does not rest on the bulbs, connectors, or solar panel lead. Leave a gentle curve between supports instead of pulling the strand taut. Keep bulbs clear of surfaces that could press against or damage them, and position the cable so it cannot snag people, pets, or moving doors.
Tip: If the strand is longer than the route, do not coil excess cable tightly around a support. Follow the manufacturer’s guidance for unused length and avoid sharp bends.
Check: The strand hangs evenly, the support points carry its weight, and the cable is not stretched, pinched, or obstructing a walkway.
Step 5: Mount the solar panel
Attach the panel to its stake, bracket, or other supplied mount, then place it where direct sunlight reaches its face. Secure the stake in firm soil or fix the bracket to a stable surface using the included hardware. Aim the panel toward the strongest available daylight, following any angle guidance in the product manual. Route its cable back to the light strand without leaving it loose across a path or pinning it under a door. Keep the panel clear of standing water and sprinkler spray unless its instructions permit that exposure.
Tip: Do not mount the panel where a tree, fence, or roof will shade it at the time of day when sunlight is most available.
Check: The panel is firmly mounted, faces open daylight, and its cable reaches the lights without tension or a trip hazard.
Step 6: Set the operating mode and charge
Connect all plugs fully, close any weather covers, and select the operating mode you want, such as steady or flashing, if available. Put the switch in the position the manual specifies for nighttime operation and charging. Leave the panel in direct sunlight for the recommended charging period. If no period is listed, give it a full day in strong daylight before assessing brightness. Avoid moving the panel into shade during this initial charge.
Tip: Cloudy weather and short winter days can reduce charging. A weak first night after poor daylight does not by itself show that the installation has failed.
Check: Connections are seated, the selected mode is set, and the panel has had the recommended initial charging time.
Step 7: Check the lights after dark
After sunset, check whether the strand turns on automatically or use the manual control as directed. Walk the full route and inspect the bulbs, cable, hooks, and panel connection. Confirm that the light level suits the area and that the strand stays clear of people and obstacles. If the set does not turn on, test the switch and light sensor, then use the troubleshooting checks below before changing the mounting layout.
Tip: Solar lights are usually decorative rather than a replacement for bright task lighting or required safety lighting.
Check: The lights turn on as expected, remain attached, and illuminate the planned area without creating a snag or trip hazard.
Common Mistakes to Avoid
- Placing the solar panel in shade or behind glass. — Mount it outdoors in a spot with substantial direct daylight, and check for shade at different times of day.
- Pulling the strand taut or letting bulbs carry its weight. — Use enough support points to carry the cable, and leave a gentle curve between fixings.
- Assuming the lights are defective before charging them. — Remove any shipping tab, set the switch as directed, and allow the specified charging time before testing at night.
- Using indoor-only clips or fixings outdoors. — Choose hardware rated for outdoor exposure and suitable for the surface supporting it.
Troubleshooting
Problem: The lights do not turn on after sunset.
Solution: Check that the switch is on, all connectors are fully seated, and any pull tab is removed. Confirm the panel received daylight and that it is not facing a bright porch light that may fool its sensor. Charge it for another sunny day, then test again.
Problem: The lights are dim or switch off early.
Solution: Move the panel to a sunnier position, clean its surface with a soft damp cloth, and allow a full sunny day to recharge. Cold weather, cloudy days, aging batteries, and longer operating modes can reduce run time. Check the manual for battery replacement details and use only the specified type.
Problem: Only part of the strand lights.
Solution: Switch the set off before checking for a loose connector, damaged cable, or bulb that is not seated correctly. Follow the manufacturer’s instructions for replacing bulbs; some strands have sealed or nonreplaceable LEDs. Stop using the set if wiring is exposed or damaged.
Problem: The panel or strand moves in wind or rain.
Solution: Switch off the lights and check the mount, stakes, and clips. Reinstall loose fixings in sound supports and secure the cable without crushing it. Follow the product’s weather rating; bring the set indoors during severe weather if its instructions require removal.
What Success Looks Like
The installation is complete when the panel is firmly mounted in a sunny location, the strand is supported without tension or damage, and the lights turn on after dark following a proper charge. The cable should not cross a walkway or interfere with doors, and all outdoor connections and fixings should be positioned as the manufacturer directs. Check again after the first windy or rainy day to confirm that nothing has loosened or shifted.
Next Steps
Clean dust and leaves from the panel when they build up, and check the strand and fixings periodically, especially after strong wind. If brightness drops, first improve sun exposure and charging time; replace a rechargeable battery only when the product instructions allow it and specify a compatible type. Before freezing weather or a storm, follow the manufacturer’s storage and removal advice. Keep the manual and any spare bulbs or approved batteries where you can find them.
Frequently Asked Questions
How many hours of sunlight do solar string lights need?
The required charging time varies by panel and battery. Follow the product instructions; when they do not specify a duration, give the panel a full day in direct sunlight before judging nighttime performance. Shade and cloudy weather reduce the charge.
Can I put the solar panel somewhere sunny and hang the lights somewhere shaded?
Yes, if the panel cable reaches and the manufacturer permits that arrangement. Keep the cable within its approved length, route it safely, and do not stretch or pinch it.
Should I switch the lights off during the day?
That depends on the model. Many sets charge with the operating switch in the on position, while others have separate controls. Follow the manual’s charging instructions rather than guessing.
Can solar string lights stay outside in rain?
Only if the lights, panel, and connections have an outdoor weather rating suitable for the conditions. Check the product label and manual, and protect or remove the set when required by its instructions.
Why do my lights work for fewer hours in winter?
Winter days are shorter, the sun is lower, and cloud cover or cold temperatures can reduce charging and battery performance. Move the panel to the clearest available sunlight and check whether the battery is due for replacement.
