How much do solar panels cost?

Thinking of installing solar panels on your home? You’re not alone! Solar power is becoming increasingly popular as people become more aware of the benefits.

But how much are solar panels, and what are the other costs involved in getting them up and running? Keep reading to find out.

How do solar panels work?

Put simply, solar panels are devices that convert sunlight into electricity. They consist of solar cells – also known as photovoltaic cells. When light hits a solar cell, it causes the electrons in the cell to flow, creating an electric current.

Solar panels are usually made from silicon, a material that is very good at absorbing sunlight. The solar cells in a panel are connected together in series so that they can generate enough electricity to power devices such as lights and motors. Solar panels can be used to power homes, businesses, and even spacecraft. They are a clean and renewable source of energy, and their use is growing rapidly around the world.

What different types of solar panels are available?

PV solar panels are an excellent way to reduce your carbon footprint and save on energy costs. However, if you’re looking to install solar panels at home, you may have noticed that there are several types to choose from. While most have a silicone base, as mentioned above, each style or variety comes with its own pros and cons. So, which should you choose and how much will they set you back?

As a general rule of thumb, a standard 250W solar panel in the UK costs between £400 and £500. According to the Energy Saving Trust, solar panel coverage for UK houses costs between £2,900 and £9,000, averaging at around £5,400 for a three-bedroom house.

Of course, there are many factors that can affect solar panel prices, a major one being the type you choose.

Let’s explore the types of solar panels available to install so you can find the best option for you.

Mono-crystalline solar panels

Mono-crystalline solar panels are made from a single crystal of silicon, which is a semiconductor. They are also known as single-crystal solar panels or mono-silicon solar panels. Mono-crystalline solar panels are the most efficient type of solar panel, and they are popular in residential and commercial applications.

Mono-crystalline solar panels are also less likely to be damaged by hail or other objects.

They tend to be more expensive than other types of solar panels, but they generate more electricity per square foot. You’ll usually be looking at £1 to £1.50 per watt.

Poly-crystalline solar panels

These panels consist of several small crystals, which gives them their characteristic matte finish. Poly-crystalline solar panels are typically less efficient than other types of panels but they are also usually less expensive. On average, they cost between £0.90 and £1 per watt.

As a result, they are a popular choice for people who want to install solar panels on a budget. In addition, poly-crystalline solar panels typically have a longer lifespan than other types of panels, making them a good investment in the long run.

Thin-film solar panels

Thin-film solar panels feature thin layers of semiconductor materials, typically just a few micrometres thick. The most common thin-film materials are cadmium telluride (CdTe) and copper indium gallium selenide (CIGS).

Unlike conventional crystalline silicon solar cells, which are rigid and fragile, thin-film solar cells are flexible and can be deposited onto a variety of substrates, including glass, plastic, and metal. This makes them well-suited for a wide range of applications, including building-integrated photovoltaics (BIPV), consumer electronics, and transportation.

Thin-film solar panels have several advantages over their crystalline counterparts. They are less expensive to produce and can be made on a much larger scale. You’ll be looking at £0.41 and £0.82 per watt.

They are also more efficient at converting low-light (such as diffuse sunlight) into electricity. However, thin-film solar panels currently have lower power outputs than crystalline silicon solar cells, and they are less resistant to high temperatures. Despite these challenges, thin-film solar panels offer great promise for the future of renewable energy.

Solar panel styles

When it comes to solar panel styles, there are three main types:

  • Mounted: These are fixed in place on your roof or another structure.
  • Portable: You can move these panels around and set them up in different locations.
  • Integrated: These solar panels are built into the roof of your home or another structure.

When choosing the right solar panel for your home, there’s no one-size-fits-all answer. It all depends on your budget, your energy needs, and your personal preferences.

What other factors can affect the cost of solar panels?

Several other factors can impact the amount you spend on fitting solar panels. It’s important to take these into account when planning your solar panel installation.

The size of coverage you need

Ultimately, the larger your solar array, the more solar panels you’ll need to purchase, and the more expensive your system will be.

Your home’s location

The location of your solar array can also affect the cost of solar panels. If you live in an area with lots of sunlight, you’ll likely need fewer solar panels to generate the same amount of power as someone who lives in a shadier location.


The cost of solar panels has dropped significantly in recent years, making them a more attractive option for homeowners looking to reduce their energy costs. However, the initial installation cost can still be a barrier for some people. Labour costs are likely to cost between £1,000 and £1,500.

Be wary – if you go for a DIY option, you could end up paying around £300 more. It pays to get a professional in!

Can solar panels increase your home’s value?

Solar panels are becoming increasingly popular as homeowners look for ways to reduce their energy costs. But can they also increase your home’s value? The short answer is yes. Solar panels can make your home more energy-efficient, and they can also serve as an attractive property feature if you ever decide to sell.

Energy efficiency is one of the most sought-after features in a home – and solar panels can help you achieve it. By generating your own electricity, solar panels can significantly reduce your energy bills. This makes your home more affordable to operate, and it will be a selling point for potential buyers. Solar panel systems can add up to 3% to a home’s resale value.

So if you’re thinking about installing solar panels, know that they could not only save you money but also make your home more valuable.
