How Solar Panels Work In The Rainy Seasons?

Posted 11 months ago by Manual Thomas

It is a common misconception that solar panels don’t work when it rains

Solar panels produce energy from the sun, not rain! 

Many people are surprised to learn that solar power systems perform better in stormy weather conditions. 

Read on for more information about how solar panels work in the rainy seasons and other questions you might have about renewable energy sources during this time of year.

How Do Solar Panels Work?

Solar panels are made up of solar cells which work by using the photovoltaic effect. 

There is a positive and negative side to each cell, known as electrodes, with one being more sensitive than the other. 

When energy from sunlight reaches these two plates they become charged in opposite directions producing an electrical current.

Are There Distinct Forms Of Sunlight That May Be Used To Generate Electricity?

Yes, sunlight can be used in two ways – direct and indirect.

Direct sunlight: is the most effective type of energy for a generation. 

This occurs when solar panels are hit directly by light from the sun. 

Once this form of electricity has been collected it must pass through an inverter which will change DC power to AC power so that it can be used in the home.

Indirect sunlight: is any light that has to pass through clouds of dust before reaching solar panels. 

This form of energy cannot produce as much power so it must be converted into AC power by an inverter which then sends electricity to your appliances and devices just like direct sunlight does. 

Homeowners with solar panels should receive direct sunlight as much as possible during the day.

How Do Solar Panels Work During Cloudy Weather?

As we mentioned, Photovoltaic panels can use direct or indirect sunlight to generate power, though they are most effective in direct sunlight.

This means solar panels will still work even when the light is reflected or partially blocked by clouds.

Solar panels will continue to perform even if the light is reflected or partially obscured by clouds, but their energy production capacity will be reduced. 

On days when there is a lot of cloud cover, solar panels will generate 10 to 25% of their regular power production.

Do The Rains Help When They Come?

The rains are a good thing when it comes to solar panels. 

Because clouds do not affect how well electricity is generated by these cells.

Instead, cloudy weather can be a benefit for homes that use solar energy since this reduces the amount of direct sunlight hitting cells, thus reducing the temperature. 

With lower temperatures, solar panels can generate more electricity during cloudy weather so homeowners need to know that this time of year can be a good thing!

The rain helps solar panels last longer due to their ability to reduce dust build-up on cells which naturally improves their performance over time. 

While there is no direct correlation between how much it rains and the lifespan of solar panels, homeowners should be happy to know that these cells can operate well in wet weather conditions.

Is There Any Risk Of Solar Panels Being Damaged By Rain?

There is very little risk of damage to solar panels when it rains since they are water-resistant.

There have been some reports though, that heavy rain can cause a small number of problems with the cells in these panels.

So homeowners should stay alert during periods of intense rainfall and keep an eye on their system’s performance. 

If you notice any issues like power outages it can be a good idea to clean the panels. This will keep them in working order for years to come!

How Do I Get More Energy During The Rainy Season?

If you want to get even more out of these renewable sources it’s important to use every resource possible when there are storms in the forecast. 

In addition to using your appliances and devices normally, try turning off lights that are not in use, turning down the temperature on your thermostat by a few degrees, or other simple ways to save energy during stormy weather. 

If you have an electric car then this is also a great time to charge it up!

How Will I Power My House On Very Cloudy Days?

Even though cloudy days are not ideal for solar panels, they can still be used to generate energy.

As long as you have a good amount of sunlight on the days that aren’t stormy then your system should provide enough electricity throughout the entire month. 

You may also want to buy an additional battery or two if possible so that you have extra power when storms are in the forecast.

Last Words:

As long as your solar panels have direct or indirect sunlight, you should still generate energy during cloudy weather conditions. 

Use your appliances and devices normally when the clouds are out to get the most power possible from these systems.
