The amount of power that solar panels can produce in the UK varies throughout the year due to differences in the amount of sunlight and weather conditions. On average, solar panels in the UK can produce around 900-1,000 kilowatt-hours (kWh) of electricity per year per kW of installed capacity. However, this can vary significantly depending on the location, angle, and orientation of the solar panels, as well as the type of panels and inverters used.

Solar panels are most efficient at producing electricity when they are pointed directly at the sun and receive maximum sunlight. In the UK, the amount of sunlight varies throughout the year, with the summer months generally receiving more sunlight than the winter months. As a result, solar panels tend to produce more electricity in the summer and less in the winter.

For example, a solar panel system with a capacity of 5 kW installed in the UK might produce around 4,500-5,000 kWh of electricity per year. This is enough to power the average UK home, which uses around 3,800 kWh of electricity per year.

It's important to note that the actual amount of electricity produced by a solar panel system will depend on a number of factors, including the location of the panels, the type of panels and inverters used, and the efficiency of the system. To get a more accurate estimate of how much electricity your solar panel system is likely to produce, you can use an online solar panel calculator or consult with a solar panel installer.
