Solar Efficiency With East Facing Roof

Panels mounted on a standard pitch roof facing east or west will produce approximately 15 less output than panels mounted on a south facing roof of a standard pitch.

Solar efficiency with east facing roof.

Placing some solar panels facing east and some facing west will result in the total amount of electricity produced being around 12 less than if all the modules were placed facing north. If you have the option to place the panels in more of a north east or north west direction it is recommended. East and west orientation. You either accept that your output will be down to the sort of levels in the table above or you spend a little more money and try to maximise the your output with technology.

Adding modules on the north side of the roof will not add much bang for the customer s solar buck and would qualify as solar malpractice in my book. Panels on a south facing roof even laid flat will almost invariably produce more electricity that east facing panels. I get asked this a lot and there isn t really a simple answer. For homes with roofs that face to the south and that have an appropriate pitch for mounting solar panels installing an efficient home solar system is fairly straight forward because both the roof orientation and angle pitch are optimal for harvesting clean energy from the sun.

An ideal south facing roof here is pitched at 7 12 39ish degrees and the north side of that roof will produce less than half as much electricity. Can solar panels be fitted if your roof is east west facing. Tra sun and snow. Therefore directions like southwest or southeast are fine.

You also can mount solar panels on roofs that face east or west on the roof of another building like a barn or garage or on the ground.

Depending on your location and roof pitch you re going to lose somewhere between 10 20 efficiency as a result of not having panels facing in a due north direction. We are looking at installing a 5kw system lg neon 2 panels and fornius inverter on a double storey house and had initially thought of splitting the panels between our north east and west facing roofs so that we got production over most of the day 8 panels north 4 east and 4 west.

Cleve hill solar park. Just make sure there s no obstructions that would cause shade on the panels and you re golden. This arrangement is often called and east west split and has the advantage of producing a more constant output of electricity during. And while there is some indication that facing solar panels to the west can also be.

Why orientation matters with rooftop solar in general solar panels that are oriented directly east or directly west will produce about 20 percent less electricity than if they were facing south.
