Solar Photovoltaics

Also known as Solar Photovoltaics (PV), solar panel electricity systems capture the sunlight and convert it into electricity used to run household appliances and lighting. They don’t need direct sunlight to work, being able to generate electricity on a cloudy day as well. 

Benefits

  • Savings on your electricity bills – sun is your ‘energy supplier’ and sunlight is free. After you pay for the installation of your solar PV system, your electricity costs will be significantly reduced, which makes a good compensation for your investment. 
  • Reduced carbon footprint – not releasing any harmful carbon dioxide or other pollutants in the air, a typical home solar PV system could save over a ton and a half of carbon dioxide per year. 
  • Generating electricity which can be sold back to the grid – thanks to the Feed-in Tariff Scheme, you can sell the surplus of electricity generated by your system back to the grid. 
  • Requiring little maintenance and having a 25-year warranty – you need to make sure the PV system is not overshadowed by trees and is relatively clean. If you opt for panels tilted at 15°, rainfall will help you with this task. Aelonline will inform you of the exact maintenance requirements before you commit to installing the solar PV system. 

How Solar Panels Work

Solar panels consist of modules of photovoltaic cells that can be either mounted on the roof or on the ground. These cells are made from layers of semi-conducting material (usually silicon) across which light creates an electric field. The stronger the sunlight, the more electricity is produced. 

The power of a PV cell is measured in kilowatts peak (kWp) - the rate at which it generates energy at peak performance in full direct sunlight during the summer. 

Installation Cost and Savings 

The average domestic solar PV system is 4kWp and its installation costs £5,000 - 8,000 (including VAT at 5 per cent). The 4kWp system generates around 3,400 kilowatt hours of electricity, which is the rough estimate of a typical household’s electricity needs. 

PV installation costs depend on 

• The more electricity the system can generate, the more it costs, but the more it could save too.
• Larger systems are usually more cost-effective than smaller systems (up to 4kWp).
• PV panels are all about the same price per kWp, but PV tiles are more expensive than a typical system made up of panels.
• Panels built into a roof are more expensive than those that sit on top.
