How much electricity can a solar PV produce?

An average 8kwp system can produce roughly 7,400-kilowatt hours of electricity a year. If your system is eligible for the ‘Feed-In Tariff’ scheme it could generate savings and income: you would get paid for the electricity you generated and used, with any remainder you didn't use being exported to the grid. As every size of business is different, so are the possible savings.

Types of Solar PV Systems

Solar panels can be retrofitted on to an existing roof or integrated into the roof structure itself. Although the ideal angle of the panel is 30 degrees, panels can be mounted on flat roofs (with planning permission) or even ground mounted.

• A reduction in your electricity bills. As daylight is free, once you have paid for the original installation your electricity costs will be lower.
• Getting paid for electricity you produce. The government’s Feed-In Tariffs pay you for the electricity you generate, even if you use it.
• Selling surplus electricity back to the grid: if your system is generating more electricity than you need, you can sell the excess back to the grid.
• Cutting your carbon footprint. Solar electricity is a ‘green’ energy and doesn't release damaging carbon dioxide. According to the Energy Saving Trust, even a small solar PV system could save over a tonne of carbon dioxide per year – that's more than 30 tonnes over its lifetime.

Does a PV system need batteries?

A PV system connects to the national grid, so if the system is not generating enough energy (for example at night), electricity is drawn from a utility company like normal.
