Solar installations in the UK: everything you need to know

Switching to solar power can help reduce your energy costs. Solar panel installations are becoming increasingly common across the country, offering a cleaner, more affordable way to generate electricity. If you’re considering going solar, here’s what you need to know about the benefits, solutions, and key questions around solar panel systems in the UK.

Benefits of solar panel installations in the UK

Reduce your energy bills

Solar panels can significantly cut your electricity bills. By generating your own power, you rely less on energy suppliers and protect yourself from rising prices.

Lower your carbon footprint

Solar energy is a renewable and green energy source. By switching to solar, you reduce your dependence on fossil fuels and help decrease your household’s carbon emissions.

Earn money from surplus energy

Thanks to the Smart Export Guarantee (SEG), you can earn payments for any excess electricity your system exports back to the grid.

Increase your home’s value

Homes with solar panels are often more attractive to buyers and can sell faster, especially as energy efficiency becomes a key consideration.

Reliable and low maintenance

Solar panels require very little upkeep. Most systems have a lifespan of 25 years or more and come with long-term warranties.

Solar installation solutions in the UK

Roof-mounted solar panels

These are the most common systems, suitable for homes with a south-facing roof and minimal shading. Installations can be tailored to suit your roof size and energy needs.

Ground-mounted systems

If your roof isn’t suitable, a ground-mounted array could be installed in a garden or field. These systems work well for properties with more land.

Solar battery storage

Adding a solar battery to your system allows you to store unused electricity for later use, such as in the evening or during power outages. This can increase your self-consumption and reduce reliance on the grid even further.

Hybrid systems

Some installations combine solar PV with other renewable technologies such as heat pumps or EV chargers, creating a more integrated and sustainable energy solution for your home.

Financing and grants

Although the cost of solar panels has dropped over the past decade, various finance options are available to help spread the cost. Some local authorities and schemes may offer grants or incentives, particularly for households on low incomes or in fuel poverty.
