Solar panels will reduce the amount of energy used on your electricity bill. Your electricity supplier won't tell you how much solar energy you've used in any given month – the overall amount of electricity you've used will simply go down. So the electricity bill that comes after your solar panels are installed will be. You don't need to tell your energy supplier that you have solar panels– unless you want to use its SEG tariff. There's no other reason to let your energy. Your solar panels almost certainly won't cover your entire electricity bill. For at least half the year, a properly sized solar installationwill supply enough electricity to cover the average. You now have all the knowledge you need about how solar panels interact with your electricity bill. The next step is to get quotes for your own panels. Just provide a few quick details about. The average electricity bill for a three-bedroom household with a 3.5 kWp system is £236 per year. This represents a 70% saving on the amount.

Solar PV panels – convert sunlight into electricity. Inverter – this might be fitted in the loft and converts the electricity from the panels into the form of electricity which is used in the home. Generation meter – records the amount of electricity generated by the solar PV system.
Using a battery system in conjunction with your solar panels is an efficient way to harness the solar energy stored during the day for use in the evening when the panels aren't producing electricity. This is one example of how to use solar panels efficiently.
Adding a battery to your solar PV system means the battery will charge when the PV system is generating electricity that isn't being used, and then discharge when you need it next (normally that evening/night). A battery can increase the percentage of solar PV electricity you use in your house.
If your solar panels produce electricity you don't use – as the great majority of panels do – you can sign up to a Smart Export Guarantee (SEG) tariff and sell your excess solar energy back to the grid.
How does a solar system work?
The solar panels convert the light into DC electricity, and the inverter converts this DC electricity into AC electricity for use in your home. The solar system will be connected to your main electricity panel ('fuseboard').
Installing solar panels lets you use free, renewable, clean electricity to power your appliances. You can sell extra electricity to the grid or store it for later use. There are over 1.3 million installations on homes across the UK – see where the UK solar panel hotspots are. Let's look at how they work and whether they're suitable for your home.
