Solar energy is the energy derived from the sun’s rays that reach the earth. It is a renewable source of energy that has grown in popularity in recent years due to its environmental benefits and cost-effectiveness. The UK government has set a target of achieving net-zero carbon emissions by 2050, and renewable energy sources such as solar energy have a significant role to play in achieving this goal. In this article, we will explain how solar energy is extracted in the United Kingdom.
The process of extracting solar energy involves capturing the sun’s rays and converting them into usable energy. There are two main methods of extracting solar energy: photovoltaic (PV) and solar thermal.
Photovoltaic (PV) method
The photovoltaic method involves the use of solar panels to capture the sun’s rays and convert them into electricity. The panels are made up of a grid of cells, each containing a layer of silicon. When the sun’s rays hit the silicon, they knock electrons loose, creating a flow of electricity.
The panels are typically installed on the roof of a building or in an open field. They are positioned to face the sun to maximize the amount of energy they can capture. The panels are connected to an inverter, which converts the DC electricity generated by the panels into AC electricity that can be used to power appliances and devices.
Solar Thermal method
The solar thermal method involves the use of solar collectors to capture the sun’s rays and convert them into heat. The collectors are typically made up of a series of pipes that contain a heat transfer fluid, such as water or antifreeze. The fluid is heated by the sun’s rays and then transferred to a heat exchanger, where it is used to heat water or air.
Solar thermal systems are typically used for heating homes and buildings, as well as for hot water production. They can be installed on the roof of a building or in an open field.
Advantages of Solar Energy
Solar energy has many advantages over traditional energy sources, such as fossil fuels. Some of the main advantages include:
1. Renewable: Solar energy is a renewable source of energy, meaning it will never run out. As long as the sun continues to shine, we will have access to solar energy.
2. Environmentally friendly: Solar energy is a clean source of energy that doesn’t produce any greenhouse gas emissions.
3. Cost-effective: The cost of solar panels has decreased significantly in recent years, making solar energy more affordable than ever before.
4. Low maintenance: Solar panels require very little maintenance once they are installed, making them a hassle-free source of energy.
Conclusion
Solar energy is an important source of renewable energy that has the potential to play a significant role in the UK’s energy mix. The photovoltaic and solar thermal methods are both effective ways of extracting solar energy, and each has its own advantages and disadvantages. As the cost of solar panels continues to decrease, it is likely that more and more households and businesses will turn to solar energy as a clean, cost-effective, and sustainable source of energy.
