How Much Do Solar Panels Cost?

Updated: May 1

Understanding Solar Panel System Pricing in the UK

Solar panel systems have gained immense popularity throughout the UK in recent years. They offer an eco-friendly and cost-effective way to generate clean energy, reduce electricity bills, and even earn money through government incentives like the Feed-in Tariff (FiT) and the Smart Export Guarantee (SEG).

However, understanding how solar panel systems are priced can be a bit complex. In this blog, we will break down the various factors that influence the cost of solar panel systems and help you make informed decisions if you're considering going solar.

System Size

The size of your solar panel system is one of the most significant factors influencing its price. In the UK, solar panels are typically measured in kilowatts (kW). The higher the system's kW, the more electricity it can generate.

The average residential solar panel system in the UK ranges from 3 kW to 5 kW. The cost will increase as you opt for larger systems to meet your energy needs. Our solar consultants will take the time to get to know you, your home and your lifestyle in order to best advise on the ideal system size for your home's solar system, as well as future-proofing it for your future electrical needs.

Quality of Components

The quality of the components used in your solar panel system, including the solar panels themselves, inverters, and mounting structures, can significantly affect the price.

High-quality components are more efficient, durable, and often come with longer warranties. While they may be more expensive upfront, they can provide better long-term returns on your investment.

When getting a quote for your solar system make sure you're comparing apples with apples. Some installers may be proposing lower quality materials in order to undercut the competition, however this could result in you having a less efficient system, reducing the benefits of going solar in the first place and potentially costing you more in maintenance and repairs in the long run.

Battery Storage

While adding a battery can increase the upfront cost, it provides energy independence and can further reduce your reliance on the grid.

In almost all circumstances we would highly recommend this innovative technology as it allows homeowners and businesses maximise the benefits of their solar system by storing any excess energy generated by solar panels during the day for use at night or during cloudy days. If you're often out during the day, and therefore not instantly using the energy produced by your solar panels, without a battery you will experience a very limited benefit from your system.

Our solar consultants can provide guidance on the right size battery for your home, lifestyle and future needs.

Installation Costs

Installation costs are another crucial factor in determining the price of your solar panel system. Labour costs, permits, scaffolding requirements and the complexity of your installation can all impact the final price.

It's essential to hire a reputable and certified installer who can ensure a safe and efficient installation. Here at Optimum Electrics we're MCS certified solar and battery installers meaning that we have successfully completed rigorous training, assessments, and audits to ensure we possess the necessary skills and knowledge to design, install, and maintain solar PV systems effectively.

Government Incentives

In the UK, government incentives can help offset the cost of your solar panel system. The Feed-in Tariff (FiT) and the Smart Export Guarantee (SEG) have been significant incentives for solar panel owners.

While the FiT has closed to new applicants, the SEG allows you to earn money by selling excess electricity back to the grid. These incentives can impact the overall cost-effectiveness of your system. Find out more about the Smart Export Guarantee (SEG) here.

Maintenance Costs

Solar panels generally require minimal maintenance, but it's good to budget for occasional cleaning and potential repairs. Regular maintenance ensures your system operates efficiently and maximizes your return on investment.

To get an accurate estimate for your specific situation, it's essential to consult with a reputable solar installer who can provide a customised quote.
