Which factors influence the cost of solar panels in the UK?
In the UK, solar panel prices depend on several factors. Considering all these aspects before purchasing solar panels is a good idea. Let’s explore the key factors that influence the cost of solar panels in the UK and how they can impact your overall investment.
Type and size of solar panels
There are three main types of solar panels: monocrystalline, polycrystalline, and thin-film. These differ in how efficient and long-lasting they are, as well as in cost.
Monocrystalline solar panels are the most efficient, as they generate the most electricity per metre squared. However, this also makes them the most expensive option on the market.
The exact cost of monocrystalline solar panels will vary depending on the manufacturer and the size of the solar panels. As a rule of thumb, monocrystalline solar panels have their highest price point at about £1 – £1.50 per Watt.
Polycrystalline solar panels, on the other hand, have a lower efficiency rating than monocrystalline panels. That said, they are easier to produce, leading to them having a lower price point.
This solar panel type is generally priced at around 90p per Watt. Exactly how much you'll end up paying for polycrystalline solar panels depends on the manufacturer and the power output of your panels.
Thin-film solar panels are the least efficient option when it comes to a solar system, but they do come at a very attractive price. As the cheapest solar panel option on the market, thin-film solar panels cost somewhere between 40 and 80p per Watt.
When choosing a solar panel type, be sure to consider both the cost of the solar panels, as well as their efficiency, and think of which option would be most beneficial for you in the long run.
Quality and brand
The quality and brand of solar panels can impact their price. Well-established and reputable brands often offer higher-quality panels with better warranties, which may come at a higher cost. That said, investing in trusted brands ensures reliability and longevity for your solar panel system.
You can consult the table below for an indication of what some of the best solar panel brands in the UK are:
| Solar Panel Manufacturer | Average Cost (4kW System) | Warranty Period |
|---|---|---|
| SunPower | £6,600 – £7,500 | 25 years |
| Project Solar | £5,000 - £8,000 | Lifetime (99.9 years) |
| REC Group | £5,000 – £7,000 | 25 years |
| REA Solar | £5,000 – £8,000 | 25 years |
| Sharp | £5,500 – £7,000 | 12 – 25 years |
Installation complexity
The complexity of the installation process can influence the overall cost. Factors such as the type of roof (e.g., flat or pitched), accessibility, and electrical work required can affect the installation cost. This is also why it is important to know if your roof is suitable for solar panels, whether you’re getting roof-mounted or integrated solar panels.
In general, solar panel installation costs in the UK are somewhere around £300 - £500 per person per day. Generally, two installers will work together to install your solar panel system, and depending on its complexity, they can take up to 3 days to complete the installation. This means that you can expect to spend anywhere between £600 and £3,000 on labour costs alone.
Mounting systems and additional equipment
Mounting systems, such as roof racks or ground mounts, are necessary to install solar panels securely. The type and quality of the mounting system can affect the cost, which ranges from £600 to £2,500. Additionally, inverters and other components like wiring, circuit breakers, and energy storage systems (if desired) also contribute to the overall expenses.
Energy needs and consumption
The amount of energy you need and consume plays a significant role in determining the size and cost of your solar panel system. For households with low energy consumption, a 3kW solar panel system is suitable. This system size costs around £4,500 – £5,500.
Households with greater energy needs, for instance large homes with 4 or more bedrooms, will need a solar panel system with a size between 6kW and 12kW. This will also lead to higher costs, as they can range from £9,500 to £13,000. So, make sure to check your energy consumption requirements and consult a professional to determine what size solar system you need. This way, you avoid overspending on your solar panels.
Regional factors and incentives
Costs can vary regionally due to labour rates and market competition differences. Additionally, various incentives and schemes, such as feed-in tariffs or government grants, can affect the overall cost of solar panels. These incentives promote renewable energy adoption and can help offset some of the installation costs.
One of the incentives in place in the UK today that can help you alleviate the financial burden of installing solar panels is the Smart Export Guarantee (SEG). You can find out more about what it is and how it can lower the cost of solar panels below.
Make use of SEG payments to reduce solar panel costs
The Smart Export Guarantee (SEG) is a crucial policy that can help you make money from your excess solar panel energy by pumping it back into the energy grid. This is where having a high-power system can be handy, as you’ll be able to make more money from the solar energy you export.
Under the SEG, energy suppliers with over 150,000 customers are obliged to offer an export tariff to owners of any of the eligible systems, which includes homes and businesses. Since the companies decide what the tariff will amount to, different energy suppliers provide different rates. On average, you can earn about 5.5p per kWh.
| Household Size | System Size (kW) | Electricity Generated Per Year (kWh) | Average Energy Consumption (kWh) | Income Earned With SEG | Total Annual Savings With SEG | Savings After 25 Years With SEG |
|---|---|---|---|---|---|---|
| 1 bedroom | 2-3kW | 1,700 – 2,550kWh | 1,800 kWh | N/A | N/A | N/A |
| 2 bedrooms | 3-4kW | 2,550 – 3,400kWh | 1,800 – 2,700kWh | £38.5 – £41.25 | £478.5 – £481.25 | £11.962 – £12,025 |
| 3-4 bedrooms | 5-6kW | 4,250 – 5,100kWh | 2,700 – 4,100kWh | £55 – £85 | £605- £635 | £15,125 – £15,875 |
| 5+ bedrooms | 6-12kW | 5,100 – 10,200kWh | 4,100 – 8,200kWh | £55 – £110 | £1,060 – £2,055 | £26,500 – £51,375 |
To apply for the SEG, you need a supplier that is part of the scheme and then you can begin earning from your solar panels as long as you are exporting energy.
Various other incentives and solar panel grants are available in the UK to encourage the adoption of solar energy. These include the Home Energy Scotland programme, the Home Upgrade Grant, and the Energy Company Obligation. To take advantage of these incentives, staying up to date with the latest government programs and guidelines is crucial.
While the availability and specific details of solar panel grants may change, it is clear that incentives exist to help make solar panel installations more accessible and affordable. By exploring these opportunities, you can reduce the upfront cost and accelerate the return on investment for your solar panel system.
