Solar power is becoming an increasingly popular form of renewable energy in the UK. With the cost of solar panels decreasing and the government’s commitment to reducing carbon emissions, more and more homeowners and businesses are installing solar panels on their roofs. One of the key advantages of solar power is that excess energy can be fed back into the grid, providing a source of renewable energy for the wider community. In this article, we’ll explore how solar power feeds back into the grid in the UK.
Firstly, it’s important to understand how solar panels work. Solar panels are made up of photovoltaic (PV) cells, which convert sunlight into electricity. When sunlight hits the PV cells, it causes electrons to move, generating a flow of electricity. This electricity is direct current (DC), which is not suitable for use in homes and businesses as it needs to be converted to alternating current (AC).
To convert the DC electricity into AC electricity, an inverter is required. The inverter converts the DC electricity into AC electricity, which can be used to power appliances and devices in homes and businesses. Any excess electricity generated by the solar panels is fed back into the grid.
In the UK, there are two main types of solar panel systems: grid-connected and off-grid. Grid-connected systems are the most common, as they allow excess electricity to be fed back into the grid. Off-grid systems are not connected to the grid and store excess electricity in batteries for later use.
When excess electricity is fed back into the grid, it is measured by a device called an export meter. This meter measures the amount of electricity being exported to the grid, and this information is used to calculate how much homeowners and businesses should be paid for the energy they generate.
The amount homeowners and businesses are paid for their excess electricity is known as the feed-in tariff (FIT). The FIT is a government scheme that pays homeowners and businesses for the renewable electricity they generate. The FIT was introduced in 2010 and is designed to encourage the uptake of renewable energy technologies, such as solar panels.
The FIT is split into two parts: the generation tariff and the export tariff. The generation tariff pays homeowners and businesses for each unit of electricity they generate, regardless of whether it is used in the home or exported to the grid. The export tariff pays homeowners and businesses for each unit of electricity they export to the grid.
The FIT is paid for by energy suppliers, who are required by law to source a certain percentage of their electricity from renewable sources. The FIT is funded through a small levy on energy bills, which is used to pay homeowners and businesses for the renewable electricity they generate.
In conclusion, solar power is an increasingly popular form of renewable energy in the UK. When excess electricity is generated, it can be fed back into the grid and used by the wider community. The feed-in tariff is a government scheme that pays homeowners and businesses for the renewable electricity they generate. The FIT is split into two parts: the generation tariff and the export tariff. The generation tariff pays homeowners and businesses for each unit of electricity they generate, while the export tariff pays homeowners and businesses for each unit of electricity they export to the grid.
