Why are so many Brits opting for Solar energy?

Latest research shows far too many broadband customers find prices confusing and lack track transparency
- Last year alone, solar power in the UK almost doubled
- In 2020 there was a total of over 700,000 installations
- Experts believe that 10 million homes will be equipped by 2022
- This means one third of households will be utilising solar energy
- 40% of of electricity in summer months will be generated from the sun
“Solar Energy is growing in popularity with 10 million houses expected to be equipped in 2022”
The UK is installing solar panels faster than any other European country, and solar seems to be one of the most popular forms of energy generation with 80% support from the public, despite the weather conditions. Surprisingly, the country’s temperatures can make the panels more efficient, while clouds are not a problem for electricity production.
How do Solar Panel cells work?
Solar PV cells are made from layers of semi-conducting material, usually silicon.
Solar PV cells are grouped into modules, and modules are usually grouped into solar arrays. Modules and arrays come in a variety of shapes and sizes.
Most PV systems are made up of panels that fit on top of your roof, but you can also install on the ground, or fit solar tiles.
When light shines on the material, electrons are knocked loose, creating a flow of electricity. The cells don’t need direct sunlight to work, they can work on a cloudy day. However, the stronger the sunshine, the more electricity generated.
The electricity generated is direct current (DC), whereas the electricity you use for household appliances is alternating current (AC). An inverter is installed along with the system to convert DC electricity to AC.
What can benefits does Solar energy provide?
Solar electricity panels, also known as photovoltaics (PV), capture the sun’s energy and convert it into electricity that you can use in your home.
By installing solar panels you can generate your own renewable electricity.
During daylight hours, you’ll be generating electricity even on cloudy days, but during the evening you’ll be using electricity from the mains. Reducing your electricity use can help lower your bills and reduce your carbon footprint.
You can combine PV with other space-heating renewable technologies such as heat pumps, solar thermal systems and insulation.
Is Solar energy right for you?
Do you have enough space?
Space is a key consideration. As a general guide, a roof area of 10-20 square metres would be enough to deliver between 20% and 45% of the typical household’s electricity needs. This roof space will ideally face South, will be unshaded, and at a pitch angle of about 30 or 40 degrees. East- or West-facing roofs could still be considered, but North-facing roofs are not recommended.
Do you need planning permission?
No, Solar PV installations are classed as permitted developments, but always check with your local authority before installing in case there are any limits or restrictions applicable.
