Do you live in a frequently cloudy region and want to buy solar lights? Are you worried if they work on cloudy days? If yes, then you are at the right place. I have researched and curated the best solar lights for cloudy days so that your outdoor space remains lit and appealing on the cloudiest of days.

Solar Lights that Charge on Cloudy Days

Solar lights are the most convenient and easy-to-install solution for your garden or backyard lighting. They don’t require you to install new wiring to your outdoor space. You can install them where ever you want providing there should be exposure to sunlight.

What if there is not enough sunlight? What if it’s cloudy outside? Don’t worry I have come up with the solar lights that are best for cloudy days.

What qualities make a solar light best for cloudy days?

There are no solar lights specially built for cloudy days, but if you follow some tips you will be able to choose solar lights that are better than others for cloudy days and will be able to generate some energy on cloudy days.

  • It should have a large solar panel to gather more light on cloudy days.
  • The solar panel should be of good quality with more efficiency.
  • It should be tough and weather resistant to face rainwater and extreme weather.
  • The batteries should be large enough to provide good battery backup and at least 3 days of autonomy.
  • There should be another charging option like USB or socket.
  • It’s better if they turn on by using the motion sensor. It will help in reducing battery usage and light will only illuminate when someone needs it.

The solar lights that I am going to review have the majority of these qualities.

Note: Days of autonomy are potential days when no power is generated and the batteries still keep working. 3 days of autonomy mean that your solar light will keep working for three days without charging. The truth is that solar lights still charge on cloudy days, so some power is being generated. Solar-generated power combined with power left in batteries will keep the solar lights working.

1. MPOWERD Luci Solar String Lights + Power Hub

Solar Lights Buying Guide

In this guide, I will tell you some essential factors that you need to keep in mind before buying solar lights. In this guide, I have curated the best solar lights for cloudy days according to general purposes. To choose which solar light is best for you among these options. You need to go through this buying guide and select the solar light that best suits your needs.


In terms of light output, solar lights come in three different categories. Dusk to dawn, timer-controlled and motion-activated. Their names make them clear.

Dusk-to-dawn: These solar lights include sensors that can tell when it is dusk or dawn. They automatically turn on at night and turn off in the morning. Dusk-to-dawn solar lights don’t need to be operated, thus they are hassle-free. Dusk-to-dawn solar lights may have trouble lasting the entire night in places with little sunlight or during the winter.

Timer Controlled: With these solar lights, you can decide their working period. These lights are entirely under your control. Their working hours are simple to set.

Motion-Activated: If someone moves within their detection range, these lights will immediately switch on. They have sensors that can detect both animal and human movement. Solar lights that detect motion are useful for security. They serve to deter robbers and thieves by turning on automatically when someone approaches. These save battery life, making them acceptable options for areas with little sunlight.

Application and Design

Another factor to consider is the application and design of solar lights. This depends on person to person that how they want to use solar lights or where they want to use them. There are various solar lights for different applications. I have mentioned some of them below.

Solar String Lights – These solar lights have a solar panel that is exposed to the sun and a string to which several bulbs are attached. While solar string lights are decorative, they are not useful for obtaining adequate light. Your patio, garden, or backyard will look wonderful with these fairy lights. These can be utilized inside as well. You can put them in a bowl or around poles or trees with them.

Solar Pathway Lights – Solar path lights, as the name indicates, light up your path. On the sides of the pathway, these lights have stakes at the bottom that bury themselves in the ground. On top of the pathway lights are solar panels. Make sure the path receives enough sunlight for them to be charged if you’re thinking of installing pathway lights.

Solar Spot Lights – These lights have a bright, focused beam. They can be used to illuminate certain parts of your outside area. These could be used for security reasons. Solar spotlights can be installed on poles, gates, or any other prominent structure.

Solar Wall Lights – This is the best solution for lighting your exterior walls. You can get solar wall lights with motion sensing to get notified when someone approaches the boundaries of your home. When putting them, make sure they receive adequate sunshine and are not obstructed by a wall or a shed.

Solar Flood Lights – These lights will brighten your entire garden and are mounted high. The purpose of these lights is security and utility.

Solar Lanterns – Portable solar lanterns can be hung inside or outside in any location. They provide aesthetic appeal and have enough brightness to light up your surroundings.

Solar Step Lights – This is a great way to illuminate your staircase at night. Each step has a solar step lamp connected, which offers good lighting. They appear beautiful as well.

Charging and Operation Time

Charging time is the time that your solar light requires to fully charge and operation time is the solar light running time. These times vary with different solar lights. Solar light with small batteries takes less time than with larger batteries. Solar lights with large panels charge faster than lights with small panels. Consider these while buying solar lights. Choose solar lights which charge faster and have a long running time.


There are four different types of batteries used in solar lights. These are NiMH, NiCad, Lead Acid, and Lithium Ion. Lithium ion batteries are the best among these. They are smaller in size, have more capacity and have more charge cycles. The downside is that they are more expensive than other options.

Check for battery capacity. The battery capacity is represented in milliamperes per hour (MAH) or amperes per hour (AH). Look for solar lights with batteries that have higher (MAH).

Solar Panel

There are three types of solar panels. Monocrystalline, polycrystalline, and amorphous solar panels.

Monocrystalline Solar Panels: These solar panels have higher efficiency and can convert more electricity. These are the best options but are more expensive than others.

Polycrystalline Solar Panels: These solar panels are commonly used nowadays. They have a good build quality and have good efficiency as well. Polycrystalline solar panels are more affordable than monocrystalline panels.

Amorphous Solar Panels: They are thin-film solar panels. Amorphous solar panels have less efficiency and are cheaper than others.


Brightness is measured in lumens. A higher number means brighter light. Consider the amount of brightness you need. It depends on the place where you want to place them and what mood you want to create. For example, ambiance lights will have 5 to 10 lumens and floodlights would have more than 500 lumens.

Also, look for the tone of light according to your needs. Floodlights would have bright white light which may be harsh for someone. While garden or patio lights will have a warm and soft tone which improves the mood.

Weather Resistance

Solar lights need to be water and dust resistant to withstand extreme weather conditions. Waterproof and weather resistance are measured in IP rating. IP65 is considered a good rating. The first number refers to solid particles like dirt and debris and 6 is the maximum. While the second number refers to water. 5 means it is protected from low-pressure water jets from any side and 8 is the maximum which means it can be completely submerged in water for a long period.

Choose a solar light of good quality that is made from durable materials and has a good IP rating.


Price is one of the important factors. Remember that good-quality solar lights will be more expensive than low-quality solar lights. Narrow down the options by setting a budget and choosing the best options in that price bracket.
