Solar (Photovoltaic) Panel Prices in 2025
This is part of our guide to buying solar panels.
If you’re considering renewable energy for your home, learning more about solar photovoltaic panel prices in Scotland should be one of your first steps. The average cost for a residential system is between £5,500 and £7,000 but can be cheaper or free under government schemes like ECO4 and LA Flex. As a result, UK residents can benefit from secure solar panels at a reduced cost or even free through MPC Energy.
What Influences Solar (Photovoltaic) Panel Prices?
Before covering the cost of solar panels, we’ll review what influences solar (photovoltaic) prices. Fortunately, the cost of solar panels has dropped significantly over the last decade. Several factors influence solar panel prices, including the following:
System Size - Larger systems generate more electricity but come at a higher cost. Your home’s size will help determine whether a large or small system would match your energy needs.
Quality of Panels - Premium panels with higher efficiency and longevity cost more. However, they offer more benefits for energy efficiency in the long run.
Battery Storage - Adding a solar battery to store energy will increase the upfront cost but can provide long-term energy independence.
Installation Costs - Remember that your roof's complexity and accessibility can affect overall expenses. A unique roof layout may result in higher installation costs.
Market Trends - Global trends such as supply chain issues or increases in demand can impact prices. As a result, current market trends can impact solar panel prices.
While it’s important to consider these factors, government-supported schemes like ECO4 and LA Flex can significantly reduce the financial burden for eligible households. The UK government’s goal of achieving net-zero carbon emissions by 2050 also propels further investment in solar energy.
Solar Panels UK Cost
According to Solar Energy UK, the average cost of installing a 4kW solar panel system on a residential property is currently between £5,500 and £7,000. These prices include installation, inverter costs, and VAT. However, smaller or larger properties will vary in overall cost. Here’s a breakdown of the average solar panels UK cost for common household sizes:
Small, One to Two Bedrooms - A 2kW system includes an average system cost and installation of £2,500 - £3,500, while a 3kW system costs around £4,500 - £5,500.
Medium, Two to Three Bedrooms - You can expect to pay between £5,500 - £7,000 for a 4kW system with installation, while £7,000 - £8,500 is the average for a 5kW system.
Large, Four to Five Bedrooms - For larger households with multiple bedrooms, a 6kW system costs from £9,000 to £10,500. More space requires a larger system for efficient energy.
While the initial costs may seem high, the savings on energy bills and increased home value often make solar panels a worthwhile investment. Solar photovoltaic panel prices in 2025 could stay stable or decrease slightly as technology advances and materials become cheaper. As demand increases, economies of scale could lower production and installation costs, making solar energy even more affordable for homeowners.
What Are ECO4 and LA Flex?
ECO4 (Energy Company Obligation) and LA Flex (Local Authority Flexible Eligibility) are government-backed initiatives to improve energy efficiency in UK homes. Under these plans, homeowners may receive grants or subsidies to install renewable energy technologies like solar panels. These schemes target low-income households and those classified as vulnerable to fuel poverty. By making high-impact energy-saving solutions more accessible, ECO4 and LA Flex aim to reduce energy waste while helping families cut down their utility bills. With assistance from MPC Energy Ltd, you can apply for these programs and install energy-efficient measures for your home.
How Does MPC Energy Ltd Utilise These Programs?
MPC Energy Ltd partners with these government initiatives to offer solar panels at a reduced cost—or even for free—to qualifying households. If eligible, this can save you thousands and make transitioning to solar power affordable. To qualify, you must meet specific eligibility criteria, such as income thresholds or certain health issues. For example, LA Flex allows local councils to determine eligibility criteria to include people who may not qualify under ECO4 but still need support. Funding is based on the property's Energy Performance Certificate, meaning the SAP Band must increase at least two bands.
