Photovoltaic panels on northern roofs

Can you put solar panels on a north-facing roof?

This maximizes the energy production over the course of the year, through both summer and winter. Sometimes, however, the homeowner will want to add modules on the north-facing roof. This may be for aesthetic purposes, or sometimes because the south-facing rooftop isn’t fit for solar. The most common rule-of-thumb is that you simply can’t do that.

Are north facing solar panels worth the money?

With electricity prices rising, north facing solar panels are now often worth the money. Long ago, when the year was 2010, electricity was cheaper than it is now and solar panels were way more expensive. Installing solar just about made financial sense on a south facing roof. But installing on a north facing roof made absolutely no sense.

What is the best angle for solar panels in the UK?

Aside from roof orientation, the roof pitch and shading also play a significant role in solar panel efficiency. The best angle for solar panels in the UK is between 30° and 40° and, ideally, your solar panels won't be obstructed by any shade. Understanding these variables can help homeowners decide if their north-facing solar array is feasible.

What is a good roof pitch for solar panels?

A roof pitch of 41 degrees facing due south with no shading is usually required to achieve 100% effectiveness. While most experts recommend south-facing solar panels for optimal performance, north-facing panels can still be viable. The challenges associated with north-facing roofs can be overcome with proper orientation and avoiding shade.

What is the difference between north-facing and south-facing solar panels?

North-facing panels, on the other hand, generally produce much less energy than south-facing panels, and usually present challenges for homeowners looking to go solar, as panels installed on these roofs will not produce enough to make financial sense. Even if you have a north-facing roof, you still have some solar options.

What is the best alternative to solar panels on a non-optimal roof?

The best alternative to panels on a non-optimal roof are ground-mount solar installations, which can help overcome many of the limitations presented by roof-mount solar. These systems are an excellent option for individuals who don't have good roofs for solar but have some open, unshaded yard space to use.
