How Much Do Solar Panels Cost in the UK? (2023 Guide)

The cost of solar panels has been decreasing over the years, making it a more affordable option for homeowners looking to switch to renewable energy. However, the actual cost of solar panels still may vary depending on various factors, such as size and type of panel, installation costs, and location.In this article, we will provide a comprehensive guide to the cost of solar panels in the UK in 2023.

1. Solar Panel Installation Costs:

The cost of installing solar panels in the UK can vary based on several factors. These include the size of the system, the type of panels used, the complexity of the installation, and the location of the property. On average, a standard 4 kWp (kilowatt peak) solar panel system can cost between £5,000 and £8,000, inclusive of installation. It is important to obtain multiple quotes from reputable solar panel installers to compare costs and ensure a competitive price.

3-4 kW12-16£6,000 - £8,000£425
5-6 kW20-24£8,000 - £10,000£595
7-8 kW28-32£10,000 - £12,000£850
9-10 kW36-40£12,000 - £14,000£1,105

2. Panel Types and Efficiency:

The type and efficiency of solar panels significantly impact their cost. There are various types available, including monocrystalline, polycrystalline, and thin-film panels. Monocrystalline panels tend to be the most efficient and durable, but they are also more expensive. Polycrystalline panels offer a slightly lower efficiency but are generally more affordable. Thin-film panels are the least expensive option but have lower efficiency levels. The choice of panel type should be based on individual requirements and budget considerations.

3. Location and Government Incentives:

Location may impact the cost of solar panel installation, with some areas experiencing high demand for solar installations resulting in supply and demand price inflations. Before making a decision, you should research your location and determine whether you are eligible for incentives such as rebates or tax breaks. The UK government offers several incentives and solar panel grants to encourage the adoption of solar power.

The most notable scheme is the Smart Export Guarantee (SEG), which requires energy suppliers to pay households and businesses for the surplus electricity they generate and export to the grid. This can help offset the initial investment by earning income from excess energy production. Additionally, homeowners can benefit from the Feed-in Tariff (FiT) scheme, which provides payments for generating renewable energy. While the FiT scheme is no longer available for new installations, existing participants can continue to receive payments. Do check with your local council to see if there are any incentives in your area.

4. Battery Storage:

In recent years, the integration of battery storage systems with solar panels has gained traction. Batteries allow for the storage of excess energy generated during the day for later use, even when the sun is not shining. Adding battery storage to a solar panel system increases the overall cost but provides greater energy independence and the potential for additional savings. The cost of battery storage varies depending on the capacity and brand, typically ranging from £2,000 to £6,000.

5. Financing Options

If the up-front cost of solar panels is unaffordable, there are financing options available. A common option is to lease solar panels on a monthly basis. The price of leased solar panels can be around £50 per month, depending on the company and financing terms. Another option is to take out a solar panel loan. Solar loans do involve an initial credit check and are similar to any home loan.

6. Return on Investment (ROI):

When considering the cost of solar panels, it is crucial to evaluate the potential return on investment. Solar panels can generate substantial long-term savings on electricity bills, particularly as energy prices continue to rise. The payback period varies depending on factors such as energy consumption, panel efficiency, and available incentives. On average, homeowners in the UK can expect to recoup their investment within 10 to 15 years. Additionally, solar panels can increase the value of a property, providing a positive impact on its resale value

Investing in solar panels in the UK is a financially viable and environmentally responsible choice. While the upfront cost may seem significant, the long-term benefits, including reduced energy bills, potential government incentives, and a positive impact on the environment, make solar panel installation an attractive proposition. By considering factors such as installation costs, panel types, government incentives, battery storage, and return on investment, individuals and businesses can make informed decisions when determining the cost and feasibility of installing solar panels in 2023. With the UK’s commitment to renewable energy and the evolving solar industry, the future looks bright for those embracing solar power
