A typical 3 4 bedroom house will require a 3 4kwp solar panel system typically composed of 12 16 solar panels.
Power generated by a 4kwp solar panel system.
4kwp is around 5500 7800 and 5kwp works out at about 1k more.
Of course installation is slightly pricier.
So you d be crazy not to consider going larger.
Annually a 4kw solar panel system will generate enough electricity to meet the needs of a regular uk family.
The electricity generated by a solar pv system is governed by its rated power output but it s also dependent on other factors such as panel efficiency and temperature sensitivity as well as the degree of shading that the system experiences and the tilt angle and azimuth of the roof on which it s installed.
Uk firm s solar power breakthrough could make world s most efficient panels by 2021 oxford pv says tech based on perovskite crystal can generate almost a third more electricity jillian ambrose.
But don t forget with the fit almost disappearing in january 2016 maximising value from your solar setup is now just a question of maximising the energy it can generate.
Most solar panels for residential installations are around 265 watts providing a good balance between efficiency and cost.
Most homes will install several solar panels known as a solar panel system.
The output of a solar panel system can be calculated by multiplying the wattage of each solar panel by the total number of solar panels.
