What are solar panels?

Solar panels convert daylight into electricity, reducing your reliance on the National Grid and cutting your monthly bills. They are made of silicon and work on light, not just heat, so while they are most efficient in direct sun, they still generate power on cloudy UK days.

Choosing your panel type

  • Solar PV (Photovoltaic): The most common choice. These power your appliances and lighting.
  • Solar thermal: A lesser-used option used specifically to heat your water. These take up less roof space but typically have a shorter lifespan and higher maintenance needs.

While standard panels are black or blue, you can now opt for coloured panels to match your roof (though these usually cost more). Newer tech, like transparent window panels, exists but isn't yet efficient or cost-effective enough for most UK homes.

How does solar work?

Solar panels (also known as solar photovoltaics, or PV) convert sunlight into electricity. Modern panels are incredibly efficient at capturing diffused light, meaning they still generate power on typically overcast British days.

  1. 1Capturing sunlight: Solar panels are made of cells containing semi-conducting materials. When light hits these cells, it creates an electrical field.
  2. 2Conversion: The panels produce Direct Current (DC) electricity. Since your home runs on Alternating Current (AC), the power is sent to a small box called an inverter to be converted.
  3. 3Powering your home: This electricity flows into your consumer unit (fuse box) to power your lights, appliances, and gadgets.
  4. 4The grid connection: If you generate more power than you need, the excess flows back into the National Grid. If you need more than you're generating (like at night), you simply pull electricity from the grid as normal.

How much do solar panels cost in the UK?

In 2026, solar will be more accessible than ever. While prices vary based on panel quality and system size, here are the approximate averages for systems without batteries, based on the installers we work with:

System sizeAverage system costTypical household size
2kW system£4,600 – £5,8001-2 people
4kW system£5,000 – £7,0003-4 people (most common)
6kW system£6,000 – £8,000Large families (or those with EVs who charge at home)

How do you pay for solar panels?

Solar panels are expensive, but you don't always need the full amount up front. Here are three paths you should consider when buying solar panels:

Outright purchase

The fastest way to see a Return on Investment (ROI), as there are no interest costs.

Green mortgages & loans

Many UK banks now offer lower interest rates for green home improvements.

Fixed-term payment plans

Many installers offer the ability to spread the cost over 3 to 10 years. While these carry standard interest rates (APR), they allow you to go solar immediately and lock in your energy price protection.

Do solar panels save you money?

Yes, and for most households, the savings are significant. Solar helps you save money in three distinct ways.

Reduced reliance on the grid

Every unit of electricity your panels generate is a unit you don't have to buy from your energy supplier. By self-consuming your own solar power, you are effectively locking in a portion of your energy costs at 0p per kWh for the next 25 years.

Maximising savings with a battery

Without a battery, you have to use it or lose it. By adding a solar battery, you can store the free energy you generated at midday and use it at 7pm when grid prices are at their peak. This can often double your annual savings compared to panels alone.

Earning through exports

Through the Smart Export Guarantee (SEG), energy suppliers will actually pay you for the leftover energy you don't use. It acts as a steady offset against your standing charges and any night-time energy use.

What's the average solar panel return on investment?

It's difficult to give an accurate view on how long it will take to break even if you install solar panels because it's dependent on a range of variables, including:

  • How much you pay for the panels
  • Where you live
  • How much energy you use
  • How much energy you generate
  • How much energy you export

According to the Energy Saving Trust, it could take anywhere between nine and 15 years to break even. However, there are benefits in the meantime, such as protection against global conflicts causing energy price spikes.

What are the benefits of solar panels?

There are both pros and cons to investing in solar panels, so it's important to make sure you've considered all possibilities before committing to an installation.

Pros

  • Lower energy bills
  • Lower carbon footprint
  • Extra income
  • Increased property value
  • Silent energy generation
  • High reliability
  • Protection from price hikes

Cons

  • High initial outlay
  • Storage costs
  • Space and roof requirements

What happens during solar power installation?

Worried about the potential mess? Don't be. A standard UK installation is a simple process:

Scaffolding

Usually set up the day before to ensure the team's safety.

Roof prep

Mounting rails are secured to your rafters (without compromising your roof's water-tightness).

The panels

Your solar PV array is bolted to the rails and wired together.

Electrical connection

The DC power from your panels is fed into an inverter, which converts it to AC power for your home.

Handover

You receive your MCS certificate, which is required to access export tariffs.

Is my home suitable for solar panels?

For most homes, solar panels are an option. But there are some exceptions and limitations.

  • FlatsUnless you own the entire block, getting permission to install solar panels can be complicated. It depends on the floor you're on, as well as the local authorities and property managers. You may be able to fit solar panels onto a balcony.
  • Listed buildingsProperties in conservation areas or national parks may not be suitable for solar panels. Less conspicuous solar tiles could be an acceptable alternative.
  • Roof orientationA south-facing roof is best. East- or west-facing could also be an option, but a north-facing roof is unlikely to be suitable.
  • ShadeSolar panels will be less effective if they're in the shadow of trees or other buildings. Solar optimisers can help you monitor the performance of your system and improve it.
  • Roof sizeLarger roofs allow for more panels and a greater electrical output.

How long do solar panels last in the UK?

Most solar panels come with a 25-year performance guarantee. With proper maintenance, they can last 30 years or more.

Should I combine solar panels with a solar energy tariff?

To make the most of your panels, you should consider signing up for a Smart Export Guarantee (SEG) tariff, where energy suppliers pay eligible homeowners for surplus energy they send back to the grid.

Some modern SEG tariffs even allow you to sell high by exporting energy during peak hours (e.g. 4pm-7pm) for premium rates, and buy low by charging your battery from the grid when prices are at the bottom of the barrel (usually overnight).

Solar power and battery storage

Adding a solar battery lets you store the energy you generate during the day to use at night. Here are the main benefits of adding a solar battery to your home:

  • Higher self-consumption: Without a battery, you might only use 30-50% of what you generate. By adding one that can jump to 80% or more.
  • Grid independence: Protect yourself against evening peak-rate price hikes.
  • The cost: A battery typically adds £2,500-£5,000 to your installation but significantly increases your long-term savings.
