What is the optimal tilt angle for solar panels?

As a general rule, to achieve the optimal energy production annually, the tilt angle for solar panels should be the same as the site’s geographical latitude. If a solar array is located at a latitude of 50°, the optimal tilt angle would also be 50°.

Can tilt angle optimization increase solar panel output?

Proper tilt angle optimization can increase solar panel output by 10-40%, depending on the location and specific circumstances. In today’s blog post, we’ll explain tilt angles for solar panels, providing practical knowledge and actionable recommendations for maximizing your solar energy system’s performance.

Should solar panels be tilted?

Seasonal variations in the sun’s angle necessitate adjustments to the tilt of solar panels for optimal performance. In winter, a steeper angle helps capture the lower-angled sunlight, while a flatter angle is more effective in summer when the sun is higher in the sky.

Why do solar panels need a higher tilt angle?

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.

How often should a solar panel be tilted?

The importance of tilt angles doesn't stop after your system is installed. As seasons change, so does the sun's path across the sky. In many regions, fine-tuning the positioning of your solar panels a few times a year can notably improve their output.

How do I find the best angle for my solar panels?

Simply enter your address and it will provide the optimal angles for each season, as well as a year-round average angle for your specific location. An example of the calculator results.
