Solar Photovoltaic Electricity
Solar panels generate electricity by capturing the sun's energy via silicon-based photovoltaic cells. They work best on a sunny day but still generate electricity even when it's cloudy. Solar panels need very little maintenance, reduce your electricity bills and your impact on the environment, so are a very popular investment for many UK households.
You can save up to £500 per year on your bills, and around 1.3 to 1.6 tonnes per year of carbon dioxide emissions.
Solar PV Panels at a glance
- Can reduce electricity bills by up to £500 per year*
- Get paid via the Smart Export Guarantee to boost your annual savings by over £100.
- Reduce your domestic carbon dioxide emissions.
Costs and considerations
- A typical 4kWp system costs around £6,500.
- Panels work best on an unshaded, south facing roof.
- Panels last 25 years or longer, with little maintenance.
*Based on being home all day and benefiting from the Smart Export Guarantee.
How can I earn money through the Smart Export Guarantee?
If you are eligible to receive Smart Export Guarantee payments, you will benefit in two ways:
- Export tariff: your energy supplier will pay you a rate for each unit you export back to the electricity grid, so you can sell any electricity you generate but don't use yourself. To see the latest SEG tariffs, please visit the Solar Trade Association Website.
- Energy bill savings: you will be making savings on your electricity bills because generating electricity to power your appliances means you don’t have to buy as much electricity from your energy supplier. The amount you save will vary depending how much of the electricity you use on site.
- Eligible technologies: solar PV, wind power, anaerobic digestion, hydro technologies up to 5MW and mcCHP with an electrical capacity of 50kW or less.
- Meters: Smart meters will be required to measure what you export.
Battery Storage & Solar Diverters
It is now possible to buy batteries to store the energy your panels generate so that you can then use it at night. These are a great way of maximising the potential for your panels. However, these are currently not grant-funded so there is an upfront cost involved:
Additionally, solar diverters can direct excess solar power from the panels to your hot water system. Again, these are not grant-funded as present.
