Going green is becoming highly popular among homeowners in the UK, and installing solar panels is one of the best ways to make the switch. Solar energy offers numerous benefits, from lowering electricity bills to reducing your carbon footprint. Nevertheless, the initial cost of solar panel installation can be quite high.
Fortunately, several affordable options make solar panels more accessible. These include government schemes, budget-friendly installers, community solar programs, and more. If you’re considering making the switch, understanding how solar panels work and the current UK market can help you find the cheapest solar panels.
Understanding Solar Panels and the UK Market
Solar Panels use photovoltaic (PV) cells to convert sunlight into electricity, which can power homes, be stored in batteries, or be sold back to the grid.
Solar adoption is on the rise, with installations reaching a seven-year high. In 2023, 161,494 solar panels were installed—a 44.6% increase from the previous year. Government incentives like the Smart Export Guarantee (SEG) and reduced VAT on energy-saving materials have made solar energy more accessible. In addition, advancements in manufacturing have significantly lowered costs, though the cost of solar panel installation in the UK varies depending on system size, roof type, and installer.
Factors Affecting Solar Panel Installation Costs
Several factors impact the cost of solar panel installation in the UK.
- System Size
One of the biggest cost drivers, system size, depends on household energy consumption. Larger systems generate more electricity but come with higher upfront costs. - Roof Type and Orientation
The size, type, and orientation of your roof affect installation costs and efficiency. South-facing roofs receive maximum sunlight, offering better returns on investment, while flat or shaded roofs may require additional equipment, increasing costs. - Location
Your home’s location impacts the price of solar panel installation due to varying labour and transportation costs. Urban areas tend to have higher labour rates, while rural areas may face increased transportation expenses. Additionally, regions like the South of England receive more sunlight, making solar energy more efficient. - Permits and Approvals
Planning permissions, especially for listed buildings or homes in conservation areas, can add to the overall cost. Non-compliance with local regulations may also lead to additional paperwork and expenses. - Additional Features
Upgrades like battery storage, advanced inverters for better energy conversion, or monitoring systems to track performance can further increase the costs of installing solar panels on house roofs.
Key Cost Components in Solar Panel Installation
- Equipment
The most expensive part of solar installation is the equipment, including solar panels, inverters (for DC-to-AC conversion), mounting systems, wiring, and cables. Higher-quality components cost more but offer better efficiency. - Installation
Labour costs cover panel mounting, system connections, and efficiency checks. More complex installations typically cost more. - Permits and Approvals
Costs vary by location and may include planning permission, electrical inspections, and compliance with local regulations. - Additional Features
Extra features like battery storage for excess energy and smart inverters for optimised performance add to the overall cost of buying solar panels.
Strategies for Reducing Costs of Solar Panel Installation
-
Research and Compare
The first step is to research and obtain quotes from different local solar installers. Prioritise those with the Microgeneration Certification Scheme. It is crucial to compare the services, prices, warranties, after-sale services, and value-added services. It is best to read reviews and customer testimonials. You can contact reliable installers through trusted platforms like “Get a Tradesman.”
- Government Incentives
Take advantage of UK government programs like the Smart Export Guarantee (SEG), which pays for surplus energy fed back into the grid. Other incentives include reduced VAT on solar equipment and past schemes like the Feed-in Tariff (FiT) and Renewable Heat Incentive (RHI).
- Energy Efficiency
Improve your home’s energy efficiency by upgrading insulation, sealing drafts, and using energy-efficient appliances to lower overall consumption.
4. DIY Installation
Solar installation at home should be done by professional installers. However, some people get it done on their own to reduce labour costs. However, ensure you understand the technical and safety requirements before attempting this.
5. Community Solar
You can join a community solar project so that you have access to renewable energy without solar panel installation at home. These programs allow participants to share resources, eliminating upfront installation costs.
Solar Panel Installation Cost Breakdown
Exact costs depend on project specifics, but here’s an estimated price range for solar panel installation:
- Small system (2-4kW): These systems are perfect for small households. The price ranges between £5,000 and £10,000.
- Medium system (4-6kW): These are suitable for average-sized households. The cost in such cases is usually in the range of £10,000 to £15,000.
- Large system (6+kW): These systems are perfect for larger homes. The price usually starts at £15,000 and goes beyond. These are costly installations due to the complexity of the system.
These are estimates—request multiple quotes to compare and find the best deal.
Additional Considerations When Buying Solar Panels in the UK
- Return on Investment: Buying solar panels involves high upfront costs, but they offer long-term benefits. Consider the payback period and whether installation increases property value.
- Maintenance: Solar panels usually do not require too much maintenance. However, inspections are crucial and regular cleaning of debris, dirt and bird droppings ensures optimal performance.
- Environmental Benefits: Solar installation at home helps reduce carbon footprint, helping make the planet a greener space.
The Role of Technology in Solar Panel Installation
Recent technological advancements have significantly improved the solar panel installation process. Key developments include:
- Advanced Solar Panels
Modern solar panels are designed for higher energy conversion rates, generating more electricity from the same amount of sunlight. They are also more compact, requiring less installation space.
- Smart Inverters
Smart inverters are transforming how solar panels operate by optimising performance and integrating with home energy systems to improve efficiency.
- Battery Storage Systems
Advancements in battery technology have made it convenient to store excess solar energy. This allows homeowners to meet peak demands and use stored energy at night or during cloudy weather when solar generation is low.
- Solar Monitoring Apps
With mobile apps & online portals, homeowners can now track key metrics like energy production, consumption, and savings in real time, enabling them to make informed decisions.
Leveraging Technology to Maximize Savings on Solar Panel Installation
Integrating these technologies helps homeowners enhance the efficiency and value of their solar systems. For example, high-efficiency solar panels work seamlessly with smart inverters for optimal energy generation, while battery storage units ensure power is available when sunlight is not. Mobile apps provide real-time monitoring of energy production and usage, helping users manage their consumption effectively.
Cheapest Way to Get Solar Panel in the UK: Final Words
The cheapest way to install solar panels in the UK depends on different factors. Researching and comparing quotes, verifying installer credentials, and considering long-term benefits are essential steps. Leveraging technological advancements can further maximise efficiency and savings.
