Nikhil Goswami

Solar panels offer an excellent way to make your home energy efficient and good for the planet. Because of their eco-friendly and cost-efficient nature, they are more popular than ever in UK households. Solar panels are an excellent renewable energy source as they convert the sun’s rays into electricity. Solar panels are eco-friendly and leave no carbon footprint. Moreover, they recover their cost in a very short period.

A 1kW solar panel system is the cheapest to install, but you won’t be able to save as much as possible with a 6kW panel. As you can see in the table, the savings per year have increased as the system size has increased from 1kW to 6kW. On the other hand, the installation costs are also increasing as we increase the system size. If you want to install a solar panel for a roof size of 22m2, you’ll need a 3kW panel with 12 panels.

How Much Does Solar Panel Installation Cost?

Although solar panel prices will vary depending on the circumstances, we will help by giving you clear estimates. The estimated costs of solar panel installation in 2022 are as follows.

System Size Roof Size Number of Panels Suitable For Estimated Costs Electricity Bill Savings Per Year
1kW panel 8m2 4 One adult £1800 to £3000 £25
2kW panel 14m2 8 Two adults £2700 to £5300 £70

What Are the Factors That Affect the Cost of Solar Panel Installation?

Solar panel installation is a big investment, and it can seem overwhelming initially. However, it will be very cost-effective in the long run. Moreover, you can also bring down installation costs by using a few simple tips and tricks we’ll explain later. Following are the factors that affect the overall costs.

The Number of Solar Panels

The greater the number of solar panels, the higher the installation cost. Since each panel sells separately,  you’ll have to invest more if you want more solar panels. Additionally, more solar panels also add to the system’s overall efficiency. However, your supplier or trader can help you precisely determine your requirements.

For optimum performance, you should place solar panels in an unshaded area. Since solar panels need light to work, your investment will be useless in the shade or away from sunlight. Instead, you should try to clear the area nearby so that the solar panels can absorb maximum sunlight to generate electricity.

Roof Size And Angle

Although you can’t change the size of your roof or property, you must know that it also affects the installation cost. If you have a large home, you’ll have to install more solar panels, adding to the overall cost. Since larger houses have a greater electricity requirement, a bigger solar system becomes necessary. From our calculations above, you can see that a family of four or more needs around 16 to 24 or more solar panels to power your home. However, for a home with only one adult, only four solar panels will suffice and will only take up an area of 8 square metres.

Furthermore, the type of roofs, such as flat, metal, and shingle roofs, also affect your solar panel installation costs. For an angled roof, installing solar panels is easy, but for flat roofs, you will need to add scaffoldings to angle the panels, which adds to the total cost.

Location and Direction of the House

Another factor affecting the solar panel installation cost is your location. For instance, if you live in or around London, you’ll have to pay more than other locations. Moreover, a solar panel in full sunlight will make more electricity with fewer solar panels than a system in the shade.

Additionally, you should keep weather patterns and climate in mind as they will affect the equipment and system size. Furthermore, you must fix your house’s structural issues before installing solar panels. If not, you’ll have to reinstall the system, which would be more expensive.

National or Local Fitters

Like other services, local fitters are more affordable than national fitters. Since local fitters are more inclined to improve their company’s image, they offer competitive and reasonable rates compared to their national counterparts. Alternatively, national fitters focus on expensive advertising campaigns to get business.

Ease of Access

The cost of solar panel installation will also depend on ease of installation. For instance, if you have a roof in a perfect solar absorbing direction, the installation will be less costly because it will be easier. Whereas if your property has irregular rooflines, difficult angles, and skylights, installing solar panels will be harder. Also, ground-mounted solar panels are more expensive than roof-mounted systems. But if your roof is old and has structural issues, it will be more costly to install a solar panel on it, and a good idea will be to go for a ground-mounted solar panel.

How Can I Save Money on Solar Panel Installation?

Despite being a big investment, there are several measures you can take to cut down solar panels’ cost of installation. We have compiled a list of a few things you can do to reduce the upfront installation costs. Following are some tips and tricks you may find useful.

Consider the Roof Direction

A south-facing roof is perfect for solar panel installation. If you are buying a new house or building a new one, you must consider a south-facing roof, particularly if you wish to install solar panels. This way, you’ll get the maximum return on your investment as the solar panels will receive direct sunlight for a major part of the day. Moreover, roofs facing southeast and southwest are equally efficient. Conversely, roofs facing west or east are 15% less efficient.

Geographical Location

For people in the UK, if you live towards the north, your house will get less sunlight compared to a location in the South. Again, this factor is useful if you’re looking for a new home and looking forward to installing solar panels on it. Since the country’s South is hotter, a house there will positively impact the solar panels’ performance. Moreover, these solar panels will be able to absorb and collect more energy and have a greater output too. Apart from that, the labour cost also varies for solar panel installation in different areas.

Use Solar Panels on Roofs as Well as on the Ground

These days, solar panels are present on the roofs and on vast farms. They are everywhere; you can see them in malls, factories, shops, and offices because of their energy efficiency. Seeing them on vast farms is surprising as farm owners prefer solar panel installation to grazing cattle or growing crops. If you have installed a Solar panel after April 2019, you’ll notice major savings on utility bills and maximum benefits overall.

Which Type of Solar Panel Is the Best?

There are three types of solar panels include thin film, monocrystalline, and polycrystalline solar panels. Advanced and high-end solar panels are more energy efficient but have more upfront costs. Thin film solar panels are less expensive than crystalline ones, but they have lower solar efficiency and don’t last much longer either. So, compared to crystalline solar panels, you’ll need more solar panels in the thin film system to produce the same amount of energy.

Moreover, you’ll have to replace the thin film panels sooner too, and the addition of solar panels will add to the total cost of installation. Also, low-quality solar panels will seem cheaper at first, but they will cost more in the future as they are not very efficient in absorbing solar energy.

Advantages of Thin Film Solar Panels

  • Cheaper than their counterparts
  • They look more attractive because of their homogenous appearance
  • They are flexible
  • Resistant to shading and high temperatures

Disadvantages of Thin Film Solar Panels

  • Require a lot of space (low space efficiency)
  • Faster degradation

Advantages of Monocrystalline Solar Panels

  • Highest efficiency rates as made up of high-grade silicon
  • They are space-efficient
  • They yield the highest power outputs and require the least space
  • Have a long lifespan (mostly come with a 25-year warranty)
  • More efficient in warm weather

Disadvantages of Monocrystalline Solar Panels

  • They are very expensive
  • Circuit break-down can occur in case of snow or dirt

Advantages of Poly-Crystalline Solar Panels

  • They have high efficiency
  • Suitable for small and large scale installations
  • Cheaper than monocrystalline solar panels
  • More eco-friendly than monocrystalline counterparts
  • They are good for large solar farms, traffic lights, and roof-mounted arrays
  • Lower heat tolerance and less wastage of silicon

Disadvantages of Poly-Crystalline Solar Panels

  • Lower efficiency than mono-crystalline
  • Less space efficient
  • Less uniform look

What Tasks Are Necessary for Solar Panel Installation?

To start with solar panel installation, the trader or builder will first do the groundwork and make necessary arrangements. Besides that, he will also ensure that the installation of solar panels is permitted in your locality and can prove beneficial in terms of absorbing energy. Following are the main tasks that involve solar panel installation:


Scaffolding makes it easier to place solar panels on any structure or surface. Using ladders or scaffolds, you can reach heights and install solar panels in places that are otherwise difficult to access. If you want to install solar panels on complex structures like trees, scaffolding will allow you to access and make the overall installation project easier. A scaffold will make the work easier and reduce the solar panel installation time.

Installation of Mounts

Solar panel mounts are necessary for solar panels to rest on. The trader will install mounts and then place the system on these units. Highly skilled and professional traders know how to fit the mounts properly. The mounts should be in a tilt position between 18 and 36 degrees to get maximum sunlight exposure.

Mounts are also available in different types, which include pole mounts, roof-ground mounts, and flush mounts. Using these mounts, you can install the solar panels on a roof, on an RV, or beside a pole. You can also set them up as free-standing units.

Installation of Panels and Wires

After installing the mounts, the installer places the solar panels on them. This way, the trader instals the solar panels on the mounts. After placing the solar panels, they will wire them onto the system. The trader will use the right solar system wires to create and complete the circuit. Specific wires are suitable for solar panel cables; these are resistant to high temperatures, moisture, UV rays, and flames. These cables and wires are also more durable than normal wires. Traders use single wires or stranded wires for the installation of panels.

Battery and Inverter Installation

The battery and inverter play an important role in solar panel installation. Creating an electrical circuit will bring the flow to the inverter to convert DC to AC. A solar battery allows you to store the energy absorbed by the sun and then use it later to convert it into electrical energy. To simplify, let us tell you that solar panels produce DC power and that the batteries store DC power. However, most household appliances run on AC power, so an inverter converts the DC to AC. The different types of inverters for solar panels include solar inverters, battery inverters, hybrid inverters, off-grid inverters/charges, and solar charge controllers.

Testing and Connection

After completing the above tasks, a professional will test the connection and make sure they are working properly. The testing process will ensure they can capture and absorb energy so that the inverter converts it and delivers it to the household appliances. A professional should take care of all the testing tasks and connection settings because these are risky jobs because of high currents.
