Solar PV explained
Solar photovoltaic (PV) systems are made up of panels that fit on top of your roof, but you can also install them on the ground or fit solar tiles.
Solar PV cells are made from layers of semi-conducting material, usually silicon. When sunlight shines on the panels or tiles, electrons create a flow of electricity. An inverter then converts the direct current (DC) electricity generated into alternating current (AC) for use in your property.
Installing a solar PV system in Jersey won't materially reduce your carbon footprint, when replacing electricity, because the imported electricity we supply is already low carbon.
Solar PV loves the sun
Solar PV systems work best in full sunlight. They can work on cloudy days but the stronger the sunshine, the more electricity they generate. Other factors which affect performance include:
- Time of day
- Angle of the sun
- System orientation
- Cloud and shade cover
Performance is measured in kilowatt peak (kWp) - the number of kiloWatts a solar PV system will generate at its maximum performance level.
Is your roof suitable for solar?
Most solar PV systems are installed on roofs. The ideal roof for a solar array should face south, be unshaded, and at a pitch angle of about 30 or 40 degrees.
East or west-facing roofs can be used, but north-facing roofs are not recommended as they typically don't get enough sunlight.
Nearby buildings, trees or chimneys that would shade your roof will have a negative impact on the performance of your system.
Export surplus energy back into the grid
There will be times when the electricity your solar PV system generates is more than you can use or store. You can export any surplus electricity back to the grid, and we will pay you for it.
To sell your electricity back to us you will need a need a dedicated JE buy back meter on our Buy Back tariff.
