How Solar Panel Installation Is Sized for Your Roof
Although many aspects of the solar panel installations we complete could be increased in size to fit more panels on the roof, there are several factors that must be taken into account before we can determine the ideal size for your home.
Measuring Usable Roof Area
The roof area excludes the area around the ridges, chimneys, skylights and edges of the roof. Typical working areas for roof sizes can be as low as 60% of the roof area for very large roofs, and as high as 70% for small roofs.
Pitch and Orientation
South facing roofs at a pitch of 30 – 40 degrees will generate the most amount of electricity. However roofs facing East or West can still gain from Solar panel installation but with reduced kWp output.
Your Electricity Consumption
Most households use around 3,500 kWh of electricity per year. As a result, installers usually look for a 3kWp to 4kWp system for most households, which is able to use most of the electricity generated by the panels.
Shading Reduces Effective Panel Count
In terms of solar panel shading for Solar Panel Installation projects, older slate pitched roofs, hipped roofs and dormer windows can reduce output. The complexity added by these features on older properties in particular can make Solar Panel Installation on larger roof spaces more difficult than on a simple pitched roof. For information on how solar panels work and the calculations used to determine output for Solar Panel Installation, see the Energy Saving Trust.
What kWp Means on a Quote
kWp stands for kilowatt peak (kWp) and is the theoretical peak output of all the solar panels on your roof and/or on your roof and in your back garden, under ideal conditions.
Battery Storage
The size of your battery storage system will depend on the size of the array that you have installed once it has been constructed. The battery storage system will be sized in accordance with the amount of surplus generation that your system will typically generate.

Ensuring your solar energy system is correctly sized to generate maximum returns will ensure your new solar energy system will deliver its full value and never sit idle on your roof.
