Is solar panel installation worth it, and do they work at night?

Solar panels have become popular fixtures for commercial and residential properties. Because they are an alternative energy source that produces emissions-free energy, solar panels have sustained public approval since their original conception in the 1980s. Solar panel installation on your property can also be an effective way to reduce your carbon footprint. But with all these benefits, one question will inevitably surface: do solar panels work effectively at night or when it’s cloudy outside? Solar panels harness the energy of the sun to power your home while decreasing your energy bill, but because the sun isn’t consistently out, concerns over how well this environmentally friendly fixture will work in the dark are valid. And while it is true that solar panels do not produce energy at night when the power of the sun is not available to utilize, they still can produce additional energy through other methods. 

Learn more about solar panels, how energy is produced after the sun is set, and how the power in your home can remain when it’s dark or foggy outside. 

Solar panels at night

Solar panels function because of the principle called the photovoltaic effect, which is when the sunlight stimulates solar cells, and an electrical current is then produced. Because this is how the power on a property is produced using solar panels, sunlight is essential for producing electricity. Without the sunlight, the solar panels on your property will become inactive. Whether a solar panel is working or not can be gauged if the lights around the property are working, such as street lamps within the general vicinity. If these lights are off, you can assume your solar panels are inactive.

Cloudy and foggy days

Although solar panels do not work at night, they surprisingly work on cloudy and foggy days. Solar panels are able to use direct sunlight on bright days, but indirect sunlight is also viable. While you might dread a day that is overcast, you won’t have to worry about your solar panels failing to work, but their energy capacity can decrease on cloudy and foggy days. Rainy days are another weather event that won’t obstruct how a solar panel operates, and, sometimes, they can work even more effectively in the rain. As the dust particles and dirt can be washed away by the rain, your solar panels will be able to absorb more sunlight without any hindrances. 

Storing energy

When the sunlight is at its peak, your solar panels can attain more energy than is needed, and this surplus of energy can be generated at night when the solar panels become inactive. You can also opt to store a surplus of energy into a solar panel that can be added to your solar panel installation on any property. By utilizing this solar battery, excess energy stored will be able to power your property to keep your household comfortable and secure. 


Don’t let the concept of solar panels becoming inactive in the dark deter you from making this progressive and environmentally friendly purchase. By installing solar panels on your property, you can reduce your energy costs and have a fixture that produces cleaner emissions than any other energy source. By taking the initiative to store the energy from solar panels during the day, you can ensure that your solar panels can still work once the sun sets.
