For example a home in cambridge with a 280 watt solar panel that receives 4 hours of sunshine will generate 1 120 watt hours wh or 1 1 kilowatt hours kwh of electricity that day 280 x 4.
How many kwh does a solar panel produce per day uk.
On an annual basis a 4kwp solar panel system will generate enough energy to power a family sized home with nearly 5 000 hours of washing machine use just under 100 000 hours of running the fridge or nearly 1 500 hours of oven use.
A 4 kw solar panel system on an average sized house in yorkshire can produce around 2 850 kwh of electricity in a year in ideal conditions.
Domestic solar panel systems typically have a capacity of between 1 kw and 4 kw.
That s 1 kwh 1 000 watts in a day per 250 watt panel.
On average our customers create the equivalent energy to produce between 42 and 83 boils of a kettle per day.
Assuming a 30 day month an electricity generation of 1 000 kwh is equivalent to 33 33 kwh per day if the site gets 6 peak sun hours per day you need 5 56 kilowatts since no energy conversion system is perfect you cannot assume the solar array will deliver its theoretical production.
In contrast if that same home had a 320 watt solar panel it would be able to produce 1 280wh or 1 2kwh of power on that same day 320 x 4.
However keep in mind that there are many factors at play here so this is really only a rough estimate.
250 watts x 4 hours.
How much energy does a solar panel produce per square foot.
Using 4 hours of full sun gives you this equation.
If you multiply 1kwh per panel by 30 days in a month you ll find that each 250 watt rated panel will produce about 30 kwh in an average month.
