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. Discover the best angle for your solar panels with our Solar Panel Tilt Angle Calculator. Maximize energy efficiency and save money!

What is the optimal tilt angle and direction for fixed solar panels?

The table below lists the optimal tilt angle and direction for fixed solar panels for the US cities and regions by zip codes. Note: The optimal title angle does not change for different zip codes within the same city or region. Also, the optimal direction for fixed solar panels is south for the entire US.

What is the inclination angle of solar panels?

When solar panels are completely flat, the angle is 0°, whereas the angle is 90° when panels are perfectly vertical, perpendicular to the ground. The title angle is the angle between solar panels and the ground. Calculating the inclination (or tilt) angle of solar panels is a vital aspect of photovoltaic design.

What is the best angle for solar panels in Houston?

According to our calculator, the best angle for solar panels in Houston is 26.5° from horizontal. 5. Scroll down to get your optimal tilt angles by season and by month. Our calculator also calculates your best solar panel angles by season and by month, in case you're interested in adjusting the angle of your panels throughout the year.

Which factor determines the tilt angle of solar panels?

The second factor, the tilt angle, is decided by the elevation angle of the sun, i.e., at what altitude the sun is. If the sun is high in altitude, then the tilt angle would be small and solar panels would be more horizontal. For low altitudes, the tilt angle is large, and solar panels are vertical.

What angle should solar panels be positioned?

In the former half of the year, the sun will be at higher altitudes, over our heads. Thus, solar panels must be positioned nearly horizontally. In other words, panels must be angles at a lower tilt angle. For example, the optimum tilt angle in San Francisco (37.7° N, 122.4° W) between March to August, as per the calculator, is 16°.
