Diwali is just a few weeks away, and balconies, terraces and main doors across India are about to light up. If you want that festive glow without extension cords, plug points or a bigger electricity bill, solar string lights are an easy choice. They charge from sunlight during the day and switch on by themselves at dusk.
This guide covers six solar string lights available on Amazon India, from ₹399 to ₹1,113, with what each one is best for, how to pick the right length for your space, and a few tips to get the best result on Diwali night.
Quick picks

- Best for large areas: CBK 22 m, 200 LED multi-colour (₹399)
- Best multi-pack: Christmas Solar String Lights 2-Pack, warm white, IP65 (₹999)

How Do Solar String Lights Work?
Solar string lights collect sunlight through a small panel during the day, store it in a rechargeable battery, and use it to power LEDs after dark. Three parts do the job:
- Solar panel: Converts sunlight into electricity. It sits outside in direct sun and connects to the lights through a lead wire.
- Rechargeable battery: Stores that energy for the evening. Battery size affects runtime; the XERGY listing, for example, states 800 mAh.
- LED string with controller: Low-power LEDs on thin copper wire, with a controller that sets the lighting mode (steady, twinkle, wave and so on).
What happens in a day
- Daytime: the panel charges the battery.
- Dusk: a light sensor notices the falling light and switches the LEDs on automatically.
- Night: the LEDs run from the battery until it runs low or morning comes.
- Dawn: the sensor switches the lights off and charging starts again.
More sunlight means a fuller battery and a longer, brighter glow. Most strings also have a power switch on the panel, which must be ON for the automatic cycle to work.
How to Choose Solar String Lights for Diwali
- Length: Measure your balcony railing, door frame or parapet first. A 10–12 m string is enough for a typical balcony; terraces and building fronts need 20 m or more.
- Colour: Warm white looks closest to the glow of diyas. Multi-colour suits parties and kids’ rooms.
- Lighting modes: Most strings have 8 modes (steady, twinkle, wave, chase and so on). If you prefer a calm traditional look, make sure there is a steady-on mode.
- Waterproof rating: IP65 is a good minimum for outdoor use. Some listings only say waterproof without a rating, so keep those under cover.
- Battery: Battery capacity (mAh) affects how long the lights run after dark. Sellers’ runtime claims are best treated as ideal-case figures.
- Panel and wire: Check that the solar panel has a lead wire long enough to reach a sunny spot, away from the shade of your balcony wall.

The 6 Best Solar String Lights for Diwali
1. XERGY Solar Fairy String Light – 12 m, 120 LED
- Length: 39 ft (about 12 m)
- LEDs: 120 on flexible copper wire
- Battery: 800 mAh inbuilt rechargeable
- Modes: 8
- Waterproof: IP65
- Price: ₹399
On paper, this is the best-documented budget option here: length, LED count, battery size and waterproof rating are all stated. Twelve metres is enough for a balcony railing plus a door frame, and the copper wire bends easily around grills and plants. A good first choice if you only want one string.
2. Amir Solar Powered Starry String Lights – 100 LED, 33 ft
- Length: 33 ft (about 10 m)
- LEDs: 100 on copper wire, warm white
- Modes: 2 (steady on, flashing)
- Waterproof: IP65 for both lights and panel
- Price: ₹599
If you want a calm, steady warm-white glow that sits well next to diyas, the simple two-mode setup is actually a plus. It has an auto dusk-on switch and a separate power button. The listing does not state battery capacity, so expect a basic runtime. It costs more than the 8-mode options, so choose it for the look, not for features.
3. CBK Solar Fairy Colour String Light – 22 m, 200 LED
- Length: 22 m
- LEDs: 200, multi-colour
- Modes: 8
- Battery: Inbuilt rechargeable
- Waterproof: Listed as waterproof (no IP rating)
- Price: ₹399
The longest string in this list at the lowest price tier. It suits terraces, boundary walls, trees and building fronts, where length matters more than premium finish. Since no IP rating is listed, hang it where it is not directly exposed to heavy rain.
4. Christmas Solar String Lights 2-Pack – 200 LED, Warm White
- Pack: 2 strings, 200 LEDs as listed [VERIFY whether per string or total]
- Modes: 8 (including twinkle, wave, chase and steady on)
- Waterproof: IP65, both lights and panel
- Runtime claim: up to 10–12 hours on a full charge
- Price: ₹999
Two strings mean you can light two areas at once, for example the balcony and the main gate, each with its own panel. It is warm white with auto dusk-to-dawn operation. The name says Christmas, but the look works just as well for Diwali.
5. AERYS Solar Fairy String Light – 10 m, RGB
- Length: 10 m
- Colour: RGB multi-colour
- Modes: 8
- Battery: Inbuilt rechargeable
- Waterproof: IP65
- Price: ₹399
A colourful, compact option for balconies and rooms with windows. It is very similar to the CBK string above, so decide between them on length: choose AERYS for a balcony and CBK for a terrace or larger area.
6. LITVERSE Solar String Lights – 12 m, Warm White
- Length: 12 m (40 ft cord)
- LEDs: [VERIFY 100 or 120]
- Modes: 8
- Runtime claim: 6–8 hours a night
- Build: PC body and silicone cords, clips included, no tools needed
- Price: ₹1,113
The listing highlights a sturdier build and easy clip-on setup. Be aware it costs roughly three times as much as the XERGY for a similar length, so it only makes sense if the clips and build quality matter to you.
Pros and Cons of Outdoor Solar String Lights
Solar string lights save you wiring and power, but they depend on sunlight, so they suit sunny balconies and terraces better than shaded corners.
Pros
- No electricity bill and no plug point or extension cord needed
- Easy setup: hang the string and place the panel in the sun
- Switch on automatically at dusk and off at dawn
- Budget friendly: the six lights above cost between ₹399 and ₹1,113
- Reusable for Christmas, weddings, birthdays and everyday decor
- Renewable energy, so they are a greener choice than mains lights
Cons
- Runtime depends on how much sun the panel gets that day
- Cloud, haze and shorter winter days reduce charging
- Usually less bright than mains-powered string lights
- The panel needs direct sun, and its lead wire limits where you can hang the lights
- Small rechargeable batteries wear out with time and may need replacing
- Quality and waterproofing vary by seller, and some listings give no IP rating
Where to Use Solar String Lights This Diwali
- Balcony railing or window grill
- Around the main door frame
- Terrace parapet and boundary wall
- Trees, tulsi area and garden plants
- Along a gate or pergola
- Shopfront or office entrance
A simple idea: use warm white near the main entrance and diya area, and keep multi-colour strings for the terrace or kids’ corner.
Tips for Best Results on Diwali Night
- Charge early. Put the panels in direct sunlight at least one or two full days before Diwali so the battery is full.
- Switch them ON. Most strings have a power switch on the panel. If it is off, the lights will not come on at dusk.
- Avoid shade. Place the panel where it gets direct sun, not in the shadow of a wall or an awning.
- Expect weaker charging in haze. Smog or heavy cloud cuts solar charging, so runtime may be shorter around Diwali in many North Indian cities.
- Keep them away from flames. Do not wrap thin wire strings around diyas, candles or near fireworks.
- Wipe the panel. Dust on the panel reduces charging.
FAQs
Do solar string lights work on cloudy days? Yes, but they charge less, so brightness and runtime can drop.
How long do they stay on at night? Sellers claim around 6–12 hours depending on the model and battery. Real runtime depends on how much sun the panel got that day.
Can I use them indoors? Yes, as long as the solar panel sits outside or by a sunny window during the day.
Are they safe in rain? IP65-rated models handle splashes and rain. Where a listing gives no rating, keep the lights under cover.
How many strings do I need for a balcony? One 10–12 m string is usually enough for a standard balcony. For a terrace or building front, look at 20 m or longer.
Final Verdict
For most homes, the XERGY 12 m string at ₹399 is the safest budget pick because its specs are clearly stated. For a bigger terrace, the CBK 22 m string gives the most length for the money. If you want to light two areas, the 2-pack makes sense, and the Amir is the pick for a simple warm glow.
