How they work - Questions, benefits and tips
Solar lights have become one of the most popular lighting solutions for gardens, balconies and patios. They are easy to install, require no electrical wiring and use free energy from the sun. Thanks to today’s efficient LED technology and improved batteries, modern solar lights can provide both decorative and functional lighting throughout the year.
How Does a Solar lamp work?
In this guide, we explain how solar lights work, their key benefits and answer the most common questions about solar-powered lighting.
A solar light typically consists of four main components:
1. Solar Panel
The solar panel captures sunlight during the day and converts it into electricity.
2. Rechargeable Battery
The generated energy is stored in a built-in battery, which powers the light after dark. Our solar lights use lithium-ion batteries for long lifespan and efficient energy storage.
3. LED Light Source
LEDs consume very little energy while providing bright and comfortable illumination.
4. Light Sensor
A built-in sensor detects ambient light levels. When darkness falls, the light automatically turns on and switches off again when daylight returns.
Benefits of Solar Lights
SIMPLE. No electricity, no cables and no installation required.
ENERGY-EFFICIENT. Powered by the sun and consumes minimal energy.
AUTOMATIC. Turns on when it gets dark and switches off when it gets light.
Solar lights are therefore ideal for:
Gardens
Pathways
Balconies
Patios
Decks
Flower beds
Entrances
TIP! Trees are a popular place to install solar lighting. A solar-powered string light is a simple and effective way to illuminate trees and create a welcoming atmosphere in your garden.
Smart Solar Module
Our products with a solar module feature a three-step dimmer (20/65/110 lumens) and automatically turn on at dusk. At maximum brightness, the light can operate for up to 14 hours, and at the lowest setting for up to 70 hours.
The module also includes a 4-hour timer, activated by pressing and holding the button for 3 seconds.
How Long Does a Solar Light Stay Lit?
This is one of the most common questions. Runtime depends on how much sunlight the solar module receives during the day. The runtime of Markslöjd's solar module is as follows:
| Brightness | Light Output | Runtime |
|---|---|---|
| Low | Approx. 20 lumens | up to 70 hours |
| Medium | Approx. 65 lumen | up to 24 hours |
| High | Approx. 110 lumen | up to 14 hours |
During summer, the battery can often recharge fully every day, while charging may be more limited during the winter months.
Do Solar Lights Work in Winter?
Yes, but with some limitations since sunlight is less available during winter. That is why our solar lights can also be charged using the included USB-C cable.
Do Solar Lights Need Direct Sunlight?
For optimal charging, direct sunlight is recommended.
Can You Charge a Solar Light with USB?
Yes. Our models offer dual charging functionality, making them ideal for cloudy days and periods with limited sunlight.
How Do I Know How Much Battery Is Left?
Our solar lights feature a built-in battery indicator showing the remaining charge level: 25%, 50%, 75%, 100%.
Are Solar Lights Waterproof?
Yes. Our solar modules are rated IP44, providing protection against weather conditions and making them suitable for outdoor use.
Can Solar Lights Be Used on a Balcony?
Yes, solar lights are an excellent choice for balconies.
Popular options include:
Solar-powered string lights
Solar-powered table lamps
Wall lights with solar panels
Decorative ambient lighting
Frequently Asked Questions About Solar Lights
How Many Hours Does a Solar Light Need to Charge?
Typically, 5–7 hours of direct sunlight is required for a full charge.
Why Is My Solar Light Dim?
This is usually caused by insufficient charging due to limited sunlight or dirt on the solar panel, preventing efficient charging.
Can Solar Lights Stay Outdoors All Year Round?
Yes. Our solar lights are designed for outdoor use and can remain outside throughout the year. However, runtime may be reduced during winter when there are fewer daylight hours.
Do Solar Lights Use Electricity?
No. When charged by sunlight, they do not consume household electricity.
How Bright Is a Solar Light?
Brightness varies by model. Decorative solar lights typically provide between 10–50 lumens, while functional outdoor lighting can exceed 100 lumens. Our solar module includes a three-step dimmer to suit different needs, with brightness levels of 110 lumens, 65 lumens and 20 lumens.
