Domestic systems tend to range from 1 kilowatt kw to 5kw in size. The system will generate approximately 20 kwh per day and will produce around 4 500 kwh of electricity per year.

This is called the nameplate rating and solar panel wattage varies based on the size and efficiency of your panel. Power output of a 5kw solar panel system. There are umpteen factors that must be accounted for many of which are highly conditional so an estimate of electrical output must be calculated case by case.

The energy saving trust est estimates that a typical three bedroom home in the uk will use just over 3 000kw per year.

Typically a modern solar panel produces between 250 to 270 watts of peak power e g. To calculate how much electricity a solar panel will produce in a day you simply have to multiply its wattage by the number of sunlight hours. A 1kw system can produce around 850kw per year a 2kw system 1 700lw per year and a 5kw system 4 500kw per year.
