Solar panel installation angle and power

What is a solar panel angle?

The solar panel angle, also known as inclination, refers to the vertical tilt angle between the surface of the solar panel and the ground. As the sun movement varies both geographically and seasonally, you need to adjust solar panel angles specific to the latitude, season, and time of day to maximize the power output.

What is a good tilt angle for solar panels?

The tilt angle for solar panels varies specific to your location latitude, season, and time of day. Typically, an optimal angle sits between 30° and 45°. To maximize the energy conversion efficiency, use proper mount brackets, and adjust the angles and orientation in accordance with time of year and day. Still have problems?

How important is angle & orientation when installing solar panels?

When it comes to installing solar panels, angle and orientation are just as important as the panels themselves. The solar panel’s best angle determines how much sunlight your panels capture throughout the year, directly impacting energy production and ROI.

How does the solar panel angle calculator work?

Our solar panel angle calculator takes the guesswork out of panel positioning, suggesting panel tilt angles based on your location's latitude and your willingness to reposition based on the sun's seasonal dance across the sky. Start by entering your location in the search box.

What angle should solar panels be installed?

Ideally, the angle of your solar panels should be equal or close to the latitude of where they are installed. As you go further north or south, the angle of the sun in the sky decreases. To efficiently capture sunlight, solar panels need to be tilted a steeper angle.

Why do solar panels need a different angle?

Another reason the angle is critical is seasonal sunlight variation. In summer, the sun is higher in the sky, while in winter, it’s much lower. Adjusting the angle of solar panels to match seasonal changes can improve efficiency by up to 20–25% annually.
