Traditionally, solar panels require one key factor to function effectively: sunlight. This factor once limited who could use solar panels in their homes and businesses to people who lived in notoriously sunny states, such as Florida and California. Now, with modern technology, even those who live in mostly cloudy environments—like Seattle—can enjoy the benefits of solar energy. Because solar panels are affordable and eco-friendly, they are widely used all over the world as a renewable, alternative source of energy. They can be used for both powering and heating your home.

If you’re considering converting to solar energy, use this review to check out each solar panel’s pros and cons, as well as the best features each one has to offer.
How Do Solar Panels Work on Cloudy Days?
Traditional solar panels need sunlight to work properly. With the help of the photovoltaic effect, solar panels directly absorb sunlight to generate power. These panels consist of photovoltaic (PV) cells that transform sunlight into energy. Then, the panel’s PV modules generate electricity and supply it to the batteries that store it. Because solar panels convert sunlight into electricity, sunlight is vital for effective power generation.
The bottom line is that traditional solar panels don’t generate enough power if there is insufficient sunlight. However, with modern technology, that’s no longer a problem. Researchers have developed black silicon solar cells that absorb more light and produce more energy than conventional solar panels. As a result, you can now find upgraded solar panels that generate power—even under cloudy skies.
Most of theses modern solar panels either use wafer crystalline silicon cells—or thin-film cells—that help the panel convert solar power into energy. Then, the cells transmit the energy for storage. Without proper protection, moisture can damage conventional panels. However, these new solar panel systems carry a junction box at the back of the panel that works as an output interface. Consequently, this makes the panels weatherproof and durable.
The 3 Types of Modern Solar Panels That Withstand Cloudy Weather
There are three broad categories of modern solar panels that will generate energy for your home or business without having to rely solely on an abundance of sunlight. The three categories include monocrystalline solar panels, polycrystalline solar panels, and thin-film amorphous silicon solar panels. If you’re in the market for an advanced solar panel system, you should look into all three of these categories and decide which one suits your needs for solar energy the best. Below, you will see a breakdown of the difference between each type of solar panel, what they need to work, and the benefits that they provide.
Monocrystalline Solar Panels Have the Highest Efficiency Rate
Monocrystalline solar panels are the most efficient type of solar panel. These products are top of the line because of their 20% efficiency rate—the highest of all solar panels. Monocrystalline solar panels, which have a black tint, are the best option for commercial use, and they are acknowledged for their sleek, appealing look. Although it is an expensive solar panel, it gives maximum performance no matter what the outdoor conditions are, so you will never have to worry about losing productivity due to the weather. As implied by its name, the cells of a monocrystalline solar panel consist of one single silicon crystal. This composition is what makes monocrystalline solar panels more effective than polycrystalline solar panels.
Polycrystalline Solar Panels Are Sensitive to High Temperatures
Polycrystalline solar panels are another good option to consider when looking for solar panels. Slightly less efficient than monocrystalline solar panels, polycrystalline solar panels offer an efficiency rate of 15%. If you have a smaller budget but don’t want to compromise quality, you will most likely find solar panels in this category. Polycrsytalline solar panels tend to have a slightly blue tint and are relatively cheaper than other types of solar panels. However, you should be aware of some of its downfalls. Polycrystalline solar panels are sensitive to high temperatures, require a lot of space, and have lower longevity.
Thin-Film Amorphous Silicon Solar Panels Are the Cheapest Option
Thin-film amorphous silicon solar panels are the third type of solar panel that work well in cloudy weather. Thin-film amorphous silicon solar panels are commonly used, come at a low cost, and offer an efficiency of 10%—the lowest efficiency of all solar panels. Despite the fact that they are the most affordable option, they also tend to have a shorter warranty and lifespan. Not only can you use the thin-film amorphous silicon material for solar panels at home, but you can also use them for solar energy for boating, camping, and charges for electric vehicles.

How Efficient Can I Expect My Solar Panel to Be on a Cloudy Day?
An advancement in technology has improved solar panels to more be efficient without relying too heavily on sunlight. If you purchase the right solar panel, it will be able to generate energy effectively, despite the cloudy weather. It’s true that you will get a higher efficiency rate when the sonar panels are exposed to a lot of sunlight, but advanced solar panels can also use daylight to generate energy.
In fact, some solar panels, like polycrystalline solar panels, will burn out and generate little energy if they are exposed to too much sunlight. For instance, in places like Las Vegas, where the sun is immensely bright, solar energy is not as popular. However, in places like San Francisco, where there is a good mixture of sunlight and clouds, solar energy is becoming more efficient and popular.
The efficiency rate that your solar panel provides depends on the type, brand, and model of the solar panel. Keep in mind that monocrystalline solar panels produce the highest efficiency rate, with an average of 20%. Though these solar panels are the most expensive, in general, the price of solar energy has decreased, opening up the opportunity for more and more people to convert to affordable renewable energy. Other solar panels can produce an efficiency rate of anywhere between 10 and 15%. Because this is not quite as high, consider using these types of solar panels for small kitchen appliances or camping gear.
Will the Rain and Snow Affect My Solar Panels?
With cloudy days also comes rain. Not only will your solar panels be able to generate energy in cloudy weather, but they will also be able to function in the rain. In fact, modern solar panels are built to be weatherproof and durable to other factors like wind and hail. Furthermore, the rain will help maintain the solar panels by keeping them clean and washing away debris. If you live in an area that has a long rain season, you might notice a slight decrease in efficiency and production, but you will still be able to use your solar panels effectively. You can also expect the same affect when it snows. Snow will not have an affect on your solar panels or cause damage. Typically, it will melt away instantly without any problems.
In the past, solar energy could only be generated through ample sunlight. Now, with upgraded technology, modern solar panels can function just as well—if not better—in cloudy weather conditions. Solar panels are a perfect source of clean and efficient energy. Not only do they help reduce your carbon footprint, but they also help you save money on electricity. When looking at solar panels , there are various options to choose from. Each solar panel comes with its own unique features and produces its own efficiency rate.
