How much electricity can Solar PV panels produce?

A Solar PV system is measured in size according to the number of electrical units it would produce in an ideal environment. The smallest system size usually installed on a domestic property is 1 kilowatt peak. In the UK, a 1kWp system is expected to produce at least 750 kilowatt hours every year. The average household in the UK uses approximately 3,300kWh per year. Therefore a 2kWp system will produce approximately 50% of your yearly electrical requirements and also avoid around 650 kilograms of carbon dioxide emissions. With this in mind if a system had a life span of at least 25 years, a 2kWp system will generate 37,500 kWh and avoid approximately 16 tonnes of carbon dioxide emissions in it’s lifetime.
