Why Does Tilt Angle Matter?

To maximize efficiency and reduce energy costs, you’ll want to find the best solar panel tilt angle for your solar power system.

An infographic showing two examples of solar panel tilt angles: a 45 degree tilt angle with the sun low in the sky, and a 20 degree tilt with the sun high in the sky.
When the sun is lower in the sky, solar panels need a greater tilt angle to receive direct sunlight. When the sun is higher, panels require less tilt.

The goal is to catch as much direct sunlight as possible throughout the day and across seasons. So when the sun hangs lower in winter, you’d increase the panel angle. When it’s higher in summer, you’d dial it down a bit.

Location is also a key factor. Typically, the more north you go, the greater your optimal tilt angle. For example, the ideal year-round angle for Minneapolis is 33.6º, versus New Orleans at 26.6º.
