AI Customer ServiceIn the simplest terms, solar panels convert energy from sunlight into electrical power using photovoltaic (PV) cells. But how much electricity can a solar panel produce?
AI Customer ServiceNREL''s team of researchers is working to improve solar cell technology, so we may see higher efficiency panels in the future. If you live in a sunny state like California,
AI Customer ServiceHousehold solar panel systems are usually up to 4kWp in size. That stands for kilowatt 'peak' output – ie at its most efficient, the system will produce that many kilowatts per hour (kWh). A typical home might need 2,700kWh of electricity over a year – of course, not all these are needed during daylight hours.
The higher the wattage of a solar panel, the more electricity it can produce. The output will also be affected by the conditions, such as where you live, the angle of the roof, and the direction your home faces. A 350W solar panel will produce an average of 265 kilowatt hours (kWh) of electricity per year in the UK.
Daily 4kW solar PV system output in the UK: In the UK, a 4kW solar PV system, using this equation may generate 10-16 kWh per day, depending on the time of year. This estimate accounts for the lower average number of peak sun hours in the UK, which ranges from about 2.5 hours in winter to 4 hours in summer.
In the UK you can expect one kilowatt of panels to generate between 800 and 1000 units (kilowatt-hours, kWh) of electricity per year. So a well-sited domestic system of about 3.5kW peak output could produce around 3,000 to 3,500 kWh per year.
Solar panels are usually around 2m², which means the typical 430-watt model will produce 372kWh across a year. A solar panel system will need space on either side, so finding out your roof's area is only one part of working out how much solar electricity you can generate, but it's a great first step.
To contextualise the potential of solar panels: A household that installed enough solar panels to produce an average of 10kWh a day would generate around 3,650kWh annually. That would be enough power to cover the average household’s yearly electricity consumption.
