How much do solar panels cost?

Solar energy has become a popular choice for homeowners in the United Kingdom who are looking to reduce their carbon footprint and save money on their energy bills. Solar panels, which convert sunlight into electricity, are a key component of any solar energy system. But, how much do solar panels cost in the UK?

The cost of solar panels in the UK varies depending on a number of factors, including the size of the system, the type of panels used, and the installer chosen. On average, a 4kWp (kilowatt peak) solar panel system can cost between £5,000 and £8,000, including installation.

Size of the System

The size of the solar panel system is one of the biggest factors affecting the cost of installation. The larger the system, the more expensive it will be. The size of the system is determined by the amount of energy a homeowner needs to generate, which is based on their electricity usage. The average household in the UK uses around 3,100 kWh (kilowatt hours) of electricity per year, so a 4kWp system is usually sufficient for most households.

Type of Panels

There are two main types of solar panels used in the UK – monocrystalline and polycrystalline. Monocrystalline panels are generally more expensive than polycrystalline panels but are more efficient at converting sunlight into electricity. They are also more aesthetically pleasing, as they have a uniform black appearance. Polycrystalline panels are cheaper but are slightly less efficient and have a blue tint.

Installer

The installer that a homeowner chooses to install their solar panel system can also affect the cost. Homeowners should choose a reputable installer who is experienced in solar panel installation. It is also important to choose an installer who is MCS (Microgeneration Certification Scheme) accredited. This means that they have been certified by an independent body to ensure that their products and services meet the highest standards.

Other Costs

In addition to the cost of the solar panels and installation, there are also other costs to consider. These include the cost of scaffolding if it is required, the cost of connecting the system to the grid, and the cost of maintenance. Homeowners should also consider the cost of insurance, as solar panels are an expensive investment.

However, despite the initial cost of installation, solar panels can save homeowners money in the long run. The amount of money saved will depend on a number of factors, including the size of the system, the amount of energy generated, and the cost of electricity. On average, a 4kWp solar panel system can save a homeowner around £230 per year on their energy bills. This means that the system can pay for itself within 10 years.

There are also government incentives available to homeowners who install solar panels. The most popular incentive is the Feed-in Tariff (FIT) scheme, which pays homeowners for the electricity they generate and use, as well as the electricity they export to the grid. The scheme has now closed to new applicants, but homeowners who installed solar panels before the scheme closed can still benefit.

In conclusion, the cost of solar panels in the UK varies depending on a number of factors, including the size of the system, the type of panels used, and the installer chosen. On average, a 4kWp solar panel system can cost between £5,000 and £8,000, including installation. However, despite the initial cost, solar panels can save homeowners money in the long run, as well as reduce their carbon footprint. Homeowners should also consider the government incentives available, such as the now closed Feed-in Tariff (FIT) scheme.
