Enter your annual generation figure or estimated figure from your mcs certificate into the box below and click calculate.
Average solar panel output uk.
So a 3 5kw south facing domestic system will produce about 3 000kwh per year.
Therefore an average 4kwp system will yield approximately.
A solar panel s output is expressed in watts.
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.
You will see a breakdown of estimated generation across the year.
Well when solar irradiance exceeds 1 000 watts per square metre solar panels are rarely able to absorb more than about 85.
8 7 x 3 x 0 85 22 2kwh per day in july.
2 35 x 4 9 4kwh on an average day.
The uk s annual insolation is in the range of 750 1 100 kilowatt hours per square metre kwh m.
So if you have a 3kwp solar pv system this would be its expected electricity output in the uk in july.
When we discuss output of the solar panel we usually use it s wattage.
For residential applications a typical solar panel is about 260 270 watts meaning that in perfect conditions that solar panel could produce 260 watts of power in a given instant for reference an led light bulb uses about 10 watts.
Domestic systems tend to range from 1 kilowatt kw to 5kw in size.
Most residential solar panels on today s market are rated to produce between 250 and 400 watts each per hour.
So here are some of the basic facts for the average domestically used solar panel system.
In average uk weather conditions you can expect one kilowatt of panels to generate between 700 and 900 units kilowatt hours kwh of electricity per year.
Solar panels usually range in wattage output from around 250 watts to 400 watts but some panels exceed the 400 watt mark.
A 1kw system can produce around 850kw per year a 2kw system 1 700lw per year and a 5kw system 4 500kw per year.
Where you live will be a factor for example cornwall receives 30 more solar energy than northern scotland.
The solar panel with the highest watt is the sunpower e series a commercial solar panel line.
As an average figure a solar panel system should produce 2 35 kwh per kwp per day.
On average a domestic solar panel has a power output of around 265 watts although it can range anywhere from as little as 225 watts to more than 350 watts.
If you don t already have solar pv you could enter the uk average generation for a 4kw system which is 3500kwh.
The higher the wattage of a solar panel the more electricity it can produce under the same conditions.
Solar panel power output.
Domestic solar panel systems typically have a capacity of between 1 kw and 4 kw.
The top panel in the e series comes out at a whopping 435 watts.
