Solar energy, also known as solar power, is the energy harnessed from the sun. The United Kingdom is one of the countries that have embraced the use of solar energy in recent years. The country receives a significant amount of sunlight throughout the year, which makes it an ideal place for harnessing solar energy. In this article, we will explore how solar energy is harnessed from the sun in the United Kingdom.
Solar Energy Collection
The first step in harnessing solar energy is the collection of sunlight. This is done using solar panels or photovoltaic (PV) cells. Solar panels are made up of multiple PV cells that are connected together. These cells are made up of layers of silicon, which is a semiconductor material. When sunlight hits the PV cells, it excites the electrons in the silicon, causing them to move and create an electric current.
The efficiency of solar panels depends on several factors, including the type of PV cells used, the angle and orientation of the panels, and the amount of sunlight received. In the United Kingdom, the angle and orientation of solar panels are critical factors due to the country’s latitude and weather patterns.
Solar panels are typically installed on rooftops or in open spaces such as fields or on the ground. The angle and orientation of the panels are adjusted to maximize the amount of sunlight they receive. In the United Kingdom, solar panels are usually installed at a tilt of around 30 degrees and facing south to capture the most sunlight.
Solar Energy Conversion
Once the solar panels have collected the sunlight, the next step is to convert it into usable electricity. This is done using an inverter, which converts the DC (direct current) electricity generated by the PV cells into AC (alternating current) electricity that can be used in homes and businesses.
The inverter is connected to the solar panels and to the electrical grid. When the solar panels generate more electricity than is needed, the excess electricity is fed back into the grid. This is known as net metering and is a key feature of solar energy systems.
Solar Energy Storage
Solar energy can also be stored in batteries for later use. This is particularly useful for off-grid systems or for homes and businesses that want to reduce their reliance on the grid. In the United Kingdom, solar energy storage is becoming increasingly popular as the cost of batteries continues to decrease.
Batteries can store excess solar energy generated during the day for use at night or during periods of low sunlight. This can help reduce energy bills and provide backup power during power outages.
Solar Energy Benefits
There are several benefits to harnessing solar energy in the United Kingdom. First, solar energy is a renewable and clean energy source, meaning it does not produce greenhouse gas emissions or contribute to climate change. Second, solar energy can help reduce reliance on fossil fuels and imported energy sources. Third, solar energy can help reduce energy bills for homes and businesses. Finally, solar energy can increase energy security and provide backup power during power outages.
Conclusion
Solar energy is a promising source of renewable energy in the United Kingdom. It is harnessed by collecting sunlight using solar panels, converting it into usable electricity using an inverter, and storing excess energy in batteries. Solar energy has several benefits, including reducing reliance on fossil fuels, reducing energy bills, and increasing energy security. As the cost of solar panels and batteries continues to decrease, more homes and businesses in the United Kingdom are likely to adopt solar energy systems.
