Do Solar Panels Work in Winter, on Cloudy Days, in the Shade or at Night?

The quick answer is YES. Of course, solar panels work even during shady days or in the winter. Solar panels can still generate electricity by capturing light from the sun even on cloudy days, though they may produce less electricity than when the sky is clear.

Not convinced? In this guide, we'll run down the process of how solar panels and generators can work in winter or during cloudy days. You'll also learn how to maximize your solar panel system's efficiency when the sun isn't shining brightly.

How Solar Panels Work 

Unlike what most people think, solar panels work by absorbing the sun's light and not the temperature. So even if the temperature outside is cold, solar panels will still be able to generate power.

Solar panels convert sunlight into electricity using photovoltaic cells, which absorb the sun’s light and turn it into direct current (DC) power. This DC power can then be converted into alternating current (AC) by Jackery portable power stations for our homes or businesses.

This process is known as the photovoltaic effect. It starts with sunlight hitting the photovoltaic cells, which are composed of materials that create an electric field. When a photon from the sun’s light hits this electric field, it creates an electron flow or current. This current is captured and stored for use as electricity.

Solar cells come in different shapes and sizes, but they all work the same way. They absorb the light from the sun and convert it into electricity.

So, even though solar panels can still generate electricity on cloudy days, they won't be as efficient as when there is direct sunshine because of the less sunlight available for them to absorb. Similarly, solar panels may also produce less energy in winter when the sun is at a lower angle in the sky and there are fewer hours of daylight.

To maximize your solar panel system's efficiency, you can use techniques such as optimizing the tilt angle and orientation of your panels to catch more sunlight or adding extra insulation to keep them warm on cold winter days. Additionally, some solar companies offer technology that can store extra energy generated by your system during sunny days, so you can use them on cloudy or winter days as well.

Do Solar Panels Work in Winter? 

During winter, solar panels gather energy by capturing light from the sun, just like any other season. Of course, you may not have as much sunlight available in winter due to fewer hours of daylight and the lower angle of the sun in the sky. But solar panels still generate electricity on cloudy days or in winter by absorbing what light is available from the sun or stored energy.

To maximize your solar panel system’s efficiency during winter, you can optimize the tilt angle and orientation of your panels to catch more sunlight or add extra insulation to keep them warm on cold days. Jackery solar panels contain an adjustable bracket for catching direct sunlight.

Do Solar Panels Work on Cloudy Days?

On cloudy days, solar panels still generate electricity by capturing whatever light is available from the sun. However, it’s important to note that cloudy days can greatly reduce the amount of energy produced by your system due to less sunlight being available for them to absorb.

You can make your system more efficient on overcast days by adjusting the tilt angle and orientation of your panels to capture more sunlight or adding extra insulation. Then, you can store the extra energy generated by your system during sunny days and use it on cloudy or winter days.

Do Solar Panels Work at Night? 

Yes, solar panels work at night, but they rarely generate electricity. Although some solar panels can still generate some energy from other light sources like street lights and the moon, the output is very low. Thus, solar panels go into sleep mode and become inactive.

Technologies such as solar batteries can optimize your solar system’s performance at night. Portable power station store extra energy generated by your panels during the day, so you can use them at night when solar panels cannot generate electricity from the sun.

Solar Panels that Work in the Shade 

At Jackery, our solar panels are designed to work in the shade. Our panels are optimized with advanced technologies like MPPT (Maximum Power Point Tracking) and Smart Solar Technology, which allow our panels to capture maximum light from a wide range of angles and directions, even in shade or on cloudy days. This makes them perfect for use in any environment - whether you need solar energy for your home, RV, or boat.

Jackery SolarSaga 200W Solar Panel, for example, is our most powerful, high-efficiency panel and can generate up to 200W of clean, renewable energy from the sun.

Paired with Jackery Explorer 2000 Pro, it only takes 2.5 hours to fully charge a Jackery Portable Power Station Explorer 2000 Pro using 6 SolarSaga 200. The solar panel is also compatible with other Jackery power stations. So if you already have one of our power stations, upgrading your panels shouldn't be a problem.

If you're looking for a more compact and lightweight solar panel, Jackery SolarSaga 100W is perfect for you. This panel can generate up to 100W of clean, renewable energy from the sun and is perfect for any environment - from your home to your RV or boat.

The solar panel is covered with monocrystalline silicon solar cells, which use multi-layered cell technology to generate energy from sunlight. This results in a higher conversion efficiency of up to 23%, compared to other conventional panels.

The two kickstands on the Jackery power station can be placed on any surface, allowing you to gather solar energy with just a few seconds of setup. The TPE rubber handle makes it easy to carry around when taking adventures off the grid.

Lastly, the Jackery SolarSaga 80W Solar Panel is designed for durability and easy assembly. It is IP68 waterproof and dustproof certified against harsh weather conditions. The two-meter extension cable allows you to charge your devices from a distance and is flexible enough to be used outdoors and in camping.

Conclusion 

No matter the size and type of your solar energy system, it’s important to remember that solar panels need direct sunlight to generate electricity. During cloudy days or during winter, you can optimize your system by adjusting the tilt angle and orientation of your panels or adding extra insulation. Solar batteries can also help store extra energy generated during sunny days so  you can still use your solar energy system when it’s dark outside.

Jackery offers a variety of solar panels to meet your needs. From SolarSaga 200W, 100W, and 80W, our advanced technologies can help you capture maximum light even in the shade or on cloudy days.
