What are solar panels?
Solar panels are devices that capture energy from the sun and convert it into electricity. Also called photovoltaics (PV), they can be installed on a property’s roof or in the garden.
A solar panel is made up of many cells constructed from layers of semi-conducting material, typically silicon. This material generates a flow of electricity when sunlight shines on it, which can then be used to power your home via an inverter. A battery means you can store that energy to use when you need it.
How much do solar panels cost?
The average domestic solar panel system costs around £7,000, including installation costs, according to the Energy Saving Trust. However, solar panel costs can vary depending on several factors:
-
Solar panel system size
The bigger the system, the more expensive it will be
-
Panels or tiles
Tiles cost more than panels, as they’re integrated into the building
-
Roof accessibility
If your roof is harder to access, installation costs for the PV system are higher
How much money can I save on my energy bills?
How much you can save on your energy bills with solar panels depends on a few factors, including: the size of your solar panel system, the amount of energy your household uses, and the cost of electricity in your area.
A typical solar panel system can save you around 50-70% on your electricity bills.
Plus, you can actually make money from your solar panels. When your panels generate more electricity than your household can use, this excess electricity can be provided back to the grid to be used by others. As long as both you and your supplier are signed up to the Smart Export Guarantee (SEG), you’ll be paid for that surplus electricity.

Do solar panels work when it’s not sunny?
A valid concern for Brits, as solar panels generate more electricity in sunny weather. On the bright side, solar panels don’t need direct sunlight to work – they’ll still turn energy into electricity even on cloudy days.
The addition of a solar battery storage system will store electricity generated during the day for use at night, or during cloudy periods.
Most solar panel systems produce around 1.5 kWh (kilowatt hours) per day.
How long do solar panels last for?
In general, solar panels are designed to have a lifespan of at least 25 to 30 years.
Their efficiency may decrease over time, but most manufacturers guarantee their panels will still be able to generate at least 80% of their initial output after 25 years. So it should remain energy saving, and continue slashing your electricity bills, for many years to come.
How do solar panels work with my gas and electricity supplier?
You won’t need to do anything, nor will anything change (apart from your electricity bill).
You can stay with your existing energy supplier, too. They’ll take readings from your meter and bill you as normal.
You may also be able to export your excess energy back into the grid via the Smart Export Guarantee (SEG), which you can arrange with your supplier.
Do I need to register my solar panel system?
If you’re planning to install a solar panel system in your property, you’ll need to register it with your Distribution Network Operator (DNO), the company responsible for bringing electricity to your home. Your installer will usually register it for you.
Gov.uk has a page on how to register your solar panel system.
How do I maintain my solar panel system?
Solar panels are designed to be as low maintenance as possible. So, you shouldn’t have to spend too much time or money to keep your solar panel system running well.
To help your solar panels absorb as much sunlight as possible, it’s best to keep them out of the shade.
They shouldn’t require much cleaning, either. Thanks to a hydrophobic coating, any rain that falls on the surface will fall away – washing away any dirt on the panels in the process.
However, if you live in a dusty, sandy or coastal area, or there’s a build-up of excess dirt, you may want to get your solar panel system cleaned occasionally.
