How does the solar panel system's placement and the roof's pitch affect production?

The placement and pitch of the roof play an important role in how efficiently your solar panel system produces electricity. But fortunately, modern solar panels and intelligent control are designed to handle many different conditions, so you can still get very good value from your system – even if your roof is not perfect.

Direction towards the sun

The best for solar panel production is for them to face south, as the sun is highest here and shines most directly. But both east- and west-facing roofs can easily provide good electricity production – typically only 10–20% less than a system facing south. At EcoRay, we take your roof direction into account so you get the most out of your placement.

Roof pitch

The optimal pitch is around 30–40 degrees, but solar panels still work very well at both flat and steeper angles. If your roof does not have the ideal pitch, mounting systems can adjust the angle so you get the most out of the sun.

Shade and surroundings

Shade can affect production, but modern solar panel systems with optimized panels and advanced inverters can minimize the effect of shade on the system's overall performance. Furthermore, we thoroughly analyze your surroundings and help find the best solution, so you get stable and high production year-round.

EcoRay’s approach

We use advanced tools to simulate production based on your specific roof placement, pitch, and surroundings. Our UV-coated panels are particularly effective in diffuse light, which means they also perform well on cloudy days – a great advantage in the Danish climate.
