We will also calculate how many kWh per year do solar panels generate and how much does that save you on electricity. Example: 300W solar panels in San Francisco, California, get an average of 5.4 peak sun hours per day. That means it will produce 0.3kW × 5.4h/day × 0.75 = 1.215 kWh per day. That’s about 444 kWh per year.
Though of course, if you have a solar battery, you can simply store the extra electricity and use it later. The average solar panel output per m² is 186kWh per year. Solar panels are usually around 2m², which means the typical 430-watt model will produce 372kWh across a year.
Whether they'll generate enough electricity for your home year-round will depend on: if your solar panel system works in a power cut. It may be more realistic to think about whether you can be self-sufficient for the brighter parts of the year, and then top up your energy use from the grid at other times.
That said, here are some standard facts for an average, UK domestic solar panel system. Domestic solar systems range from 1 kilowatt (kW) to 5kW in power. So, now we know how much energy a typical household uses per year let’s look at how much energy a typical 4kW solar PV / solar panel system generates.
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.
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.
