Does Rain Affect Solar Panels?

Some of the common myths when we refer to solar panels is that on those cloudy days or with the danger of suffering precipitation, there is a high risk that the solar panels do not work normally.

This is why we’re going to go into more detail about how solar panels work in bad weather and whether it’s a myth or the fact that they don’t work at all.

Does Rain Affect Solar Panels

Performance of solar panels on cloudy days

The first thing we’re going to say researchers don’t believe is that your solar panels don’t get the sun’s rays on cloudy days. This is not true. Even though it doesn’t produce as much electricity as it would on a sunny day, it doesn’t mean that it doesn’t use any energy.

The production will be less, but the solar panels will still work. This is called diffuse radiation, which means that when the sun’s rays don’t hit the panel directly, they do so through fog or clouds.

If you live in a cloudy or sunny place, a solar energy system will be able to work well. In addition, there is evidence of high solar energy catchments in places that don’t have a lot of solar power, like Boston or San Francisco in the United States or the whole of Germany.

Do solar panels generate electricity if it rains?

Yes! Thanks to current technology, solar technology can still make electricity even when it rains. We’ll then explain why that is.

Many people think that both on cloudy days and on rainy days, electricity production can be unsafe or even break down, but this is just as false as the other statements.

Rain has little effect on the use of solar panels because they can keep capturing solar energy even when there are rains in between. So you can keep saving money on your electricity bill even though it’s raining outside.

Furthermore, by using batteries in your installation, you will gain the benefit of having an isolated system that will allow you to utilize the solar energy captured by your panels with that stored in the batteries if necessary. This way, you won’t have to worry about running out of power at some point.

Can rain or hail damage solar panels?

The answer to this question is no. It should be said that solar panels are made so that they can withstand any natural disasters that may happen since the panels are meant to be outside. So don’t be afraid.

Regarding the materials that make up these solar panels, it should be said that they are resistant enough to withstand both rain and hail since we know that in places in Peru, it is pretty standard for these meteorological phenomena to occur.

It is essential for you to know that even though solar panels are outside, hail can’t get through them and break them down. This is because they have a strong shell that protects them even when they are outside.

The rain won’t hurt your solar panels, and it will help keep them clean, so you don’t have to worry about it at all.

It is important to note that the solar panel system can last for up to 30 years. This means that in order to make these panels last through the weather, you need to make sure they are high-quality. When you buy them, make sure that the company you choose is legitimate and trustworthy.

 

Why don’t the panels capture solar energy?

First, it is essential to note that there are some things that can change how well the panels use solar radiation. There could be trees that shade you from the sun, tall buildings close to your home or business, or air conditioners.

 

Why does solar energy efficiency decrease on rainy and cloudy days?

As we said above, solar energy production in rainy or cloudy periods does not cease to exist. However, its degree of functioning is between 10% and 30% because the higher concentration of clouds impairs irradiation performance.

On the other hand, it is possible to supply the demand through calculations performed by companies in order to balance the rates for the higher performance of solar panels. Although the United States has a high rate of sunny days, it will require a slight increase in power generation on low days.

 

Solution for times when solar energy is not generated

The solar battery, being found in three types: lead-acid, nickel-cadmium, and lithium ions, contributes to the functioning of its solar energy system. Therefore, the use of these batteries, connected to the grid, brings energy storage solutions when there is a power outage in the grid on rainy or cloudy days.

Still, it is worth remembering that batteries such as lead-acid and nickel-cadmium have a very high cost concerning their service life. Meanwhile, the lithium-ion battery has increased durability and storage capacity, which is ideal for on-grid systems.

Conclusion

A small amount of rain doesn’t make a big difference to how solar panels work or how much electricity they make.

It’s important to note that the company you choose sends you a quality certificate, which will help you feel more at ease about the performance of your solar panels.

You don’t have to be afraid of rain or hail because your solar panels will be safe.
