Solar PV how does it work?

A solar PV panel consists of many cells made from layers of semi-conducting material, most commonly silicon. When light shines on this material, a flow of electricity is created.

The cells don’t need direct sunlight to work and can even work on cloudy days. However, the stronger the sunshine, the more electricity generated.

A Solar PV installation is made up of several panels, with each panel generating around 355W of energy in strong sunlight. Typical systems contain around 15 panels and generate direct current (DC) electricity. Because the electricity used for household appliances is alternating current (AC), an inverter is installed along with the system to convert DC electricity to AC. This electricity can be used throughout your home, or exported to the grid. Solar PV is a renewable energy source, reducing our dependency on fossil fuels and reducing carbon emissions.

How much will I save installing solar panels?

Make real cost savings by selling energy back to the grid

The amount of money you will save is completely dependent on the system size you have installed and if you combine your system with battery storage, it will also depend on the amount of energy you consume on a typical day.  

Solar panels are a great way to generate your own electricity by using the sun’s energy, the average home can save around £540 per year and by adding battery storage could give you annual savings of up to £705 per year, this will also really help to reduce the carbon footprint of your home.

Most households will use about 15-25% of the energy you generate, though this can change quite dramatically based on:

  • Whether you work from home
  • How many people are at home during the day
  • Whether you have an electric vehicle
  • Whether you heat your home or hot water using a heat pump or other electrical heating
  • Whether your cooking is done using electricity
  • Or if you have battery storage for your system

Do I need permission to install a solar PV system?

Solar PV panels are considered ‘permitted developments’ and often don’t require planning permission. However, exceptions apply and it’s best to check with your local planning office for guidance. If you live in a listed building, conservation area or national park, additional restrictions may apply.

If you’re planning to install a solar PV system in your home, you must register it with your Distribution Network Operator (DNO). The DNO is the company responsible for bringing electricity to your home.

What Are the Benefits of Powering Your Home with Solar Energy?

Firstly, you can significantly reduce your household electricity bills by generating your own power from the sun – installing solar PV panels on your property could cut your annual electricity bill by around £705. Also, you can even earn money from your solar panels by selling any surplus electricity back to the National Grid through a scheme like the Smart Export Guarantee. 

Secondly, installing solar PV panels on your property will also reduce your home’s carbon footprint. This means you will be actively contributing to the fight against climate change. Having a solar-powered home helps to protect the wildlife and communities that are currently threatened by the warming climate; in place of using a non-renewable energy source, solar energy is a completely sustainable and environmentally-friendly alternative to supply your home with electricity. 

Lastly, A PV Solar Panel installation is easy to install and require little in the way of long-term maintenance costs. The panels can be installed directly onto the roof of your home and will begin producing electricity straight away. 

In summary, the main benefits of using solar energy in your home include:

  • Reducing your household electricity bills
  • Reducing your home’s carbon footprint
  • Reducing your home’s contribution to air pollution
  • Utilising a renewable, sustainable source of energy
  • Providing your home with an energy source that requires low long-term maintenance costs
