Do Solar Panels Work Underwater?

By Benjamin Strusnik February 16, 2022

Do Solar Panels Work Underwater

Do Solar panels work underwater? The simple answer is yes.

Solar panels are not only waterproof but can hold out against a large amount of water.

This will also affect whether solar panels work in the rain. They are specially designed to endure the elements.

They’re also constructed to withstand heavy rainfall without being damaged. Solar panels are meant to last, especially during seasons of fluctuating weather, both mild and extreme.

This is excellent, as heavy rains and storms often cause power outages. During the winter months and summer, solar panels offer consistent coverage, generating electricity from sunlight.

But how do solar panels generate energy underwater?

Let’s have a look at how solar panels work beneath the water.

How Do Solar Panels Work Underwater?

Solar panels are built to work efficiently underwater. They’re able to generate energy underwater at depths of up to 50 feet. The water should be clear and not murky.

This is important as the sun needs to penetrate the water to reach the solar panels. The further down you go, the less light makes it to the panel.

If your water is murky, your solar panels won’t be able to operate at depths more than 50 feet.

Large amounts of bacteria, algae, and other impurities can reduce the transparency of the water and make it difficult for the sunlight to activate the panels.

Clear waters improve performance by up to 55% to 65%.

The design of the solar panel can also contribute to a more efficient way to generate energy underwater.

Although solar panels work underwater, they work best out in the open. Have a look at our 100-Watt Solar Panel. It boasts a five-star review with its highly efficient functioning.

What Is the Best Weather for Solar Panels?

Solar panels work best during sunny and clear days. But what about whether solar panels work on cloudy days? Even though solar panels are more efficient during sunny days, they do work during cloudier days, but less efficiently.

Snow, however, can improve the solar panel output. The white snow on solar roof panels reflects light and thus improves the photovoltaic performance.

Can You Charge Solar Panels Without Sunlight?

At night direct moonlight shining on solar panels can generate a small amount of energy. Solar PV panels can generate moonlight into electricity.

Can solar panels work with artificial light?

Solar panels can charge with artificial light. The fluorescent bulbs can charge solar cells if the light is strong enough. But sunlight is still the best way to charge and generate energy using the solar panel. It’s faster and generates energy efficiently. 

While you can technically charge them with artificial lights, you’re going to lose a lot of energy, so we really wouldn’t recommend it.

Can Water Damage a Solar Panel?

Solar panels made to be used at home are waterproof.

They are built to endure rain, snowfall, and strong storms. Their design is made to last under extreme conditions. Submerging your solar panel underwater should not be a problem.

Solar panels generate energy through their solar cells. The electricity generated is sent through the wires of the solar panels to whatever storage device you have set up in your system.

Depending on the quality of the solar panel, the wiring can become damaged.

Solar panels are made in such a way that the wiring is protected but buying a cheaper solar panel could mean that you don’t get the same guarantee that the solar panel will withstand being submerged in water.

This is of course rare. Most solar panels will be able to handle being underwater, make sure to have a high-quality solar panel for the best warranty terms.

So we’ve answered the question of whether a solar panel would work underwater. Luckily for you, it does. Why you would ever want to install a solar panel under 50 feet of water, however, is something that not even we can answer.
