Solar energy is becoming increasingly popular in the United Kingdom as an alternative to traditional sources of energy. The UK is blessed with a relatively sunny climate, which means that solar energy is a viable source of renewable energy. In this article, we will explore where we get solar energy from.
The sun is the source of all solar energy. The sun is a giant ball of gas, mostly hydrogen and helium, that generates heat and light through nuclear fusion. The energy produced by the sun is transmitted to the Earth in the form of electromagnetic radiation, including visible light, ultraviolet radiation, and infrared radiation.
To convert solar energy into usable electricity, we need to capture the sunlight and convert it into an electrical current. This is done using solar panels, which are made up of photovoltaic (PV) cells. PV cells are made of silicon or other materials that can absorb sunlight and convert it into electricity.
The most common type of solar panel used in the UK is the crystalline silicon panel. This type of panel is made up of a thin wafer of silicon that is sandwiched between two layers of glass. The silicon absorbs sunlight and creates an electrical charge, which is then collected and sent to an inverter. The inverter converts the DC (direct current) electricity produced by the solar panels into AC (alternating current) electricity that can be used to power homes and businesses.
Solar panels can be installed on rooftops, on the ground, or on other structures such as carports or canopies. The angle and orientation of the panels are important factors in determining how much energy they can produce. In the UK, solar panels are typically installed at an angle of between 30 and 40 degrees, facing south for maximum exposure to sunlight. However, east or west-facing panels can also be effective.
Solar panels can be connected to the national grid, allowing excess energy to be exported back to the grid. This is done using a device called a solar PV inverter, which converts DC electricity produced by the panels into AC electricity that can be used in the home or exported back to the grid.
In addition to solar panels, there are other types of solar technology that can be used to generate electricity. Solar thermal systems use sunlight to heat water or air, which can then be used for heating and hot water in homes and businesses. Concentrated solar power (CSP) systems use mirrors or lenses to focus sunlight onto a small area, creating heat that can be used to generate electricity.
There are also a number of large-scale solar farms in the UK that generate electricity for the grid. These farms use thousands of solar panels to generate electricity on a commercial scale.
Solar energy has a number of advantages over traditional sources of energy. Solar energy is renewable and emits no greenhouse gases, making it a clean and sustainable source of energy. Solar panels can be installed on rooftops or other structures, making them ideal for urban areas where space is limited. Solar energy can also be generated locally, reducing the need for expensive transmission infrastructure.
In conclusion, solar energy is a viable source of renewable energy in the UK. Solar panels are the most common way of generating solar energy, and they can be installed on rooftops, the ground, or other structures. Solar energy has a number of advantages over traditional sources of energy, including renewable and emissions-free nature. The UK government is committed to increasing the use of renewable energy, including solar energy, and has set ambitious targets for the future.
