BrightGridSouth-facing solar is often associated with maximum annual generation, but east-west systems can provide a different and sometimes very useful generation profile.
Benefits of east-facing panels
East-facing panels tend to produce more electricity earlier in the day, which can align well with morning household demand.
Benefits of west-facing panels
West-facing panels tend to produce more electricity later in the day, which can align with afternoon and evening demand.
Why generation timing matters
A solar system is not only about total annual generation. The timing of generation affects how much electricity can be used directly and how much may need to be stored or exported.
East-west systems can use more roof area
On suitable roofs, panels can sometimes be installed across two opposing roof faces, increasing the amount of usable roof space.
More annual generation is not always the only goal
A system that better matches household consumption can sometimes provide greater practical value than one designed solely to maximise annual generation.
Compare roof orientations
Model different roof layouts and see how orientation affects generation and household energy use.
Compare Solar DesignsFrequently asked questions
Are east-facing solar panels worth it?
Yes. East-facing panels can provide useful morning generation and may work very well for some households.
Are west-facing solar panels worth it?
Yes. West-facing panels can provide useful afternoon generation and may match later household demand.
Is east-west better than south-facing solar?
Neither is universally better. The best layout depends on roof space, generation goals and electricity consumption patterns.
Can you install solar on both sides of a roof?
Yes, where the roof structure, orientation, electrical design and planning considerations allow it.
