Do solar panels work on cloudy days? What about at night? Or is solar energy only effective on cloudless, sunny days?
As solar energy becomes more popular, it’s important to understand how this technology works and to separate fact from fiction. Although you might think that solar panels couldn’t possibly work on cloudy days, the real answer might surprise.
So continue reading and we’ll walk you through how solar panels work when the sun isn’t shining.
Do Solar Panels Work on Cloudy Days?
To put it simply, yes. Solar panels definitely do work on cloudy days. However, they are not necessarily going to perform as well as on sunny, bright days. When it’s cloudy or rainy out, their power output will be limited.
With that said, areas that receive a lot of cloud coverage and rain are still popular locations for installing solar panels. The most important factor for deciding to install solar panels is not how sunny the area is but how much is the cost of electricity.
There are plenty of popular cities that don’t get a lot of sunlight yet still reap the benefits of solar energy. Let’s look at San Francisco as an example.
This place is famous for the heavy fog that hovers over the city for the majority of the year. Despite this fact, solar energy is wildly popular in San Francisco. In some cases, a cloud can even magnify or reflect sunlight which will result in additional power for your home.
Or take Germany. This country is known for its lack of sunlight yet it’s still a global leader in the renewable energy sphere.
Important Things to Know
It’s also worth noting that you don’t need hot weather in order to general electricity from solar panels. In fact, these appliances work best in places that are cold and sunny. When a panel gets above 77 degrees Fahrenheit, it can start to work less efficiently.
Again, it’s the cost of electricity, and not the weather, that mainly determines if solar panels can save a building owner money.
Also, it’s important to point out that partial shading can reduce the amount of solar energy that your panels are generating. If 10% of the panels are shaded by tree leaves, then your energy output will be reduced by 10%. Experienced and professional installers will know how the optimal way to install your panels so you get the most efficient outcome.
The Importance of Knowing How Solar Panels Work
Hopefully, after reading the above article, you now feel that you have the answer to the question: “Do solar panels work on cloudy days?”. There are a lot of myths out there about solar energy. And when these myths go unchecked, they can stop people from making informed decisions that will save them money while also helping the environment.
This is why it’s so important to make sure you get the facts about renewable energy before coming to conclusions.
