Now, you might wonder, what happens to that extra electricity? Can you sell it back and make money? The answer is yes, in the UK, you can sell the extra energy your solar panels produce.
In this article, we will explain how you can sell excess energy from solar panels in the UK. We will talk about what you need to know, how much you can earn, and the benefits of doing so. By the end, you will know everything about selling extra solar energy and if it’s the right choice for you.
How Solar Panels Work: Generating and Storing Energy
Solar panels use sunlight to make electricity. They are made of special materials called photovoltaic (PV) cells. When sunlight hits these cells, it creates an electric current. This current is then sent to your home to power lights, appliances, and other devices.
Sometimes, solar panels make more electricity than your home needs. This is common on sunny days when your panels are working at full power, but you might not be using much electricity. The extra electricity that isn’t used is called excess energy.
This excess energy doesn’t have to go to waste. It can either be stored in batteries or sent back to the power grid. Batteries are a great solution because they store the extra energy, which can be used later when the sun isn’t shining. This way, you don’t always have to rely on the grid for power, and it can save you money.
What Is Excess Solar Energy and Why Is It Important?
Excess solar energy is the extra electricity that your solar panels create but your home doesn’t use. When your solar panels are working well, especially on sunny days, they often produce more energy than you need. This extra electricity is called excess energy.
Having excess energy is great for homeowners because it offers multiple benefits. First, it allows you to sell this extra energy back to your energy provider, which means you can make money. The more excess energy your panels produce, the more you can sell. This can lead to lower energy bills and help you earn money for the electricity your home doesn’t use.
Secondly, using solar energy helps reduce your carbon footprint. When you produce more electricity from solar panels, you’re relying less on fossil fuels, which helps the environment. By selling excess energy, you’re contributing to the clean energy movement in the UK.
Can You Sell Excess Energy from Solar Panels in the UK?
Yes, you can sell excess energy from solar panels in the UK. When your solar panels generate more electricity than you use, the extra power can be sent back to the national grid, and you can earn money from it. This is possible through a government-backed scheme called the Smart Export Guarantee (SEG).
The Smart Export Guarantee (SEG) was introduced in January 2020, replacing the old Feed-in Tariff (FiT) scheme. Under SEG, energy companies must pay homeowners for the excess energy they send back to the grid. Each energy supplier sets its own rates, so it’s important to compare different providers to get the best deal.
The UK government supports solar energy through regulations like the SEG, encouraging more people to switch to renewable energy sources. By selling excess energy, you can offset some of the costs of installing solar panels and even make a profit over time.
