Slv photovoltaic panels

What is a solar PV system?

Solar PV systems – a collection of solar panels – turn sunlight into electricity through the ‘solar cells’ they contain. These cells are made from thin layers of a ‘semiconductor’ material (traditionally silicon) between layers of glass.

What is a solar panel inverter?

Inverters are pivotal in transforming solar power into usable home energy, and your solar energy system cannot work without it. Screwfix provides two primary types of solar panel inverters: These devices convert DC from your solar panels into AC, integrating seamlessly with the home's electrical grid.

How much does a solar PV system cost?

According to the Energy Saving Trust, the average domestic solar PV system is 3.5kWp (kilowatt peak – the amount it will generate when working optimally) and costs about £7,000. Check out our guide to solar panel costs for a more in-depth breakdown of system prices and savings.

Can solar panels be installed on a south-facing roof?

To maximise the amount of solar energy produced, solar panels are best installed on a south-facing roof, ideally at a 35° angle. Solar panels can be installed on a west-facing or east-facing roof too, but these won’t generate as much power. A north-facing roof will receive the least direct sunlight, so is not recommended.

Should you buy a solar PV system for your home?

Well-chosen solar panels can provide a reliable source of renewable electricity for decades, helping to slash your electricity bills and cut your carbon footprint. But buying an inappropriate solar PV system for your home could leave you out of pocket.

What are the different types of solar panels?

The most common type of solar panel system used for domestic homes is PV – photovoltaic – panels. They collect energy from the sun in photovoltaic cells, which is then passed through an inverter to generate electricity. Each photovoltaic cell is made up of a series of layers of conductive material. Silicon is the most common.
