Are solar panels worth installing in the UK?

With the growing popularity of renewable energy sources, solar panels are increasingly being considered for their potential to generate sustainable power. This article provides a comprehensive overview for electricians, contractors, and consumers on the key considerations for solar panel installations.

Financial benefits of solar panels

Installing solar panels can significantly reduce your electricity bills. On average, a UK household can break even on the installation costs in approximately 14.1 years and save up to 64% on their electricity expenses. However, the actual costs and savings depend on several factors, including:

• Your location

• Your electricity consumption patterns

• The size of your solar PV system

• Current electricity prices

• Payments received for excess energy exported to the grid

Solar panels are a worthwhile investment if they meet your energy needs and if you plan to stay in your home long enough to recover the installation costs. Additionally, using solar energy helps reduce your carbon footprint and supports environmental sustainability.

Installation costs of solar panels

The cost to install a 4-kW solar PV system in the UK is around £8,000. This price includes the system size, necessary fittings, inverter costs, and labour for installation and testing. Labour costs typically range between £300 and £500 per person, per day, with the installation of a 4-kW system usually taking 1-2 days, resulting in total labour costs between £600 and £1,200.

While higher efficiency panels and those with longer warranties may have higher initial costs, they often result in greater long-term savings. Larger systems and those with battery storage will also have higher upfront costs but offer increased savings on energy bills. Excess energy can be sold back to the National Grid through the Smart Export Guarantee Scheme (SEG). However, the price per kWh for exported electricity is generally lower than the price you pay for consumed energy.

How many solar panels are needed?

The number of solar panels required varies by house size: sufficient for a 3-to-4-bedroom house. The power output depends on the panel type, location, system size, orientation, angle, and sunlight exposure.

• A one-bedroom house typically needs six panels.

• A three-bedroom house generally requires ten panels.

• A five-bedroom house usually needs fourteen panels to cover approximately 46% of the household’s annual electricity usage.

Lifespan and warranty

Solar panels usually last between 25 to 30 years, with newer models potentially lasting up to 40 years or more. Most panels come with a manufacturer’s warranty of 10 to 25 years, guaranteeing at least 80% efficiency after 25 years. Modern panels degrade at a rate of around 0.2% to 0.3% per year. Inverters and batteries typically have warranties ranging from 5 to 15 years.

As solar panel technology becomes more affordable and efficient, their potential for long-term energy savings makes them an attractive investment. By considering installation costs, the required number of panels, energy production, and panel lifespan, you can make an informed decision about whether solar panels are right for you.

Solar panel energy production

Individual solar panels typically generate between 200 to 450 kW of electricity per hour. In the UK, a standard domestic solar panel system comprises 10 to 14 panels, producing 2,600 to 3,700 kWh of electricity annually,
