According to our calculator, a 4.5 kilowatt (kW) system with 12 panels would produce on average 4,100 kilowatt hours (kWh) in a year, enough for a 3 bedroom house. However, there are a range of factors that can affect how much electricity your solar panels produce, from the efficiency of your system to the angle of your roof.
The simplest way to measure how much energy a solar panel produces is to multiply the panel’s power rating by the amount of direct sunshine it gets. A powerful panel bathed in hours of sunshine could generate as much as 2kWh (kilowatt hours) of electricity in a day – which is sufficient to power a small household all day in summer.
According to Statista, in 2023 UK solar panels generated an impressive 15,225 gigawatt hours of electricity. That means solar PV (photo voltaic) panels produced about 3% of the UK’s electricity last year. Now, that may not sound like much, but remember in 2004 the number of gigawatt hours generated by solar was just four.
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.
Multiplying this value by 30 days, we find that such a solar panel can produce around 54 kWh of electricity in a month. In states with sunnier climates like California, Arizona, and Florida, where the average daily peak sun hours are 5.25 or more, a 400W solar panel can generate 63 kWh or more of electricity per month.
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.
