Solar Panels. A Guide For UK Homeowners. Solar Panel Installers Essex.

Solar energy is one of the most abundant and clean sources of energy on Earth. It can be harnessed by using solar panels, which are devices that convert sunlight into electricity or heat. Solar panels can be installed on rooftops or ground-mounted, and they can provide a range of benefits for homeowners, such as reducing energy bills, increasing property value, and lowering carbon emissions.


In this article, we will explain the different parts of a solar panel system, how they work, and how much they cost. We will also provide some statistics on solar panel installations in the UK and show how solar energy is contributing to the country’s renewable energy mix.


What are the parts of a solar panel system?


A typical solar panel system for household use consists of three main components: solar panels, batteries, and inverters.


Solar panels are made up of photovoltaic (PV) cells, which are thin layers of semiconductor material (usually silicon) that absorb photons (light particles) from the sun and knock electrons loose. These electrons flow through a circuit and create an electric current that can be used to power appliances or stored in batteries.


Batteries are devices that store excess electricity generated by solar panels for later use.


They can help balance the supply and demand of electricity, especially during peak hours or when there is no sunlight. Batteries can also provide backup power in case of grid outages or emergencies.


Inverters are devices that convert direct current (DC) electricity from solar panels or batteries into alternating current (AC) electricity that can be used by most household appliances or fed into the grid. Inverters also regulate the voltage and frequency of the electricity to match the grid standards.


How do solar panels work?


Solar panels work by converting sunlight into electricity through a process called the photovoltaic effect. The amount of electricity that a solar panel can produce depends on several factors, such as:

  • The size and efficiency of the panel

  • The angle and orientation of the panel

  • The amount and intensity of sunlight

  • The temperature and weather conditions

  • The shading and dirt on the panel

The electricity generated by solar panels can be used in two ways: self-consumption or grid export.


Self-consumption means using the electricity directly in your home to power your appliances or charge your batteries. This can help you reduce your reliance on the grid and save money on your energy bills.


Grid export means sending the excess electricity to the grid and getting paid for it by your energy supplier. This can help you earn some income from your solar panel system and support the growth of renewable energy in the UK.


How much do solar panels cost?


The cost of installing solar panels depends on several factors, such as:

  • The size and type of the system

  • The quality and brand of the components

  • The location and condition of your roof

  • The complexity and duration of the installation

  • The availability of grants, incentives, or financing options

According to Money Saving Expert, the average cost of installing a 4kW solar panel system in the UK is £6,500. However, this price can vary significantly depending on your specific situation and preferences.


The good news is that the cost of installing solar panels has decreased by 82% in the last decade, according to the International Renewable Energy Agency. This means that solar panels are becoming more affordable and accessible for homeowners across the UK.


If you are looking for solar panel installers in Essex, you can compare quotes from different companies online or ask for recommendations from friends or family. Solar panels Essex is a popular search term for people who want to find local and reliable installers in their area.

How much can you save with solar panels?


The amount of money that you can save with solar panels depends on several factors, such as:

  • The size and performance of your system

  • The amount of electricity that you use or export

  • The price of electricity that you pay or receive

  • The lifespan and maintenance of your system

According to Which Magazine, a 4kW solar panel system can save you between £90 and £240 per year on your energy bills if you use 50% of the electricity that you generate. This figure can increase if you use more electricity or have a larger system.


Additionally, you can earn money from your solar panel system by exporting your excess electricity to the grid. Under the Smart Export Guarantee (SEG) scheme, which replaced the Feed-in Tariff (FIT) scheme in 2020, energy suppliers pay you a fixed rate per kWh for every unit of electricity that you export. The rates vary depending on your supplier and contract, but they typically range from 3p to 5p per kWh.
