Solar Panel Tilt Angle Calculator

The Solar Tilt Angle Calculator is a tool designed to help users determine the optimal tilt angle at which to install solar panels (also known as photovoltaic panels) in order to maximize the efficiency of solar energy collection. The efficiency of solar panels is affected by the angle at which they are mounted, as the position of the sun in the sky varies over time and geographic location. Therefore, by adjusting the tilt angle of your solar panels, you can ensure that they maximize their ability to face the sun, thereby capturing more solar energy and converting it into electricity.

Enter your location's latitude and the day of the year to calculate the optimal tilt angle for your solar panels:



Solar Tilt Formula

The following formula is used to calculate the optimal tilt angle for solar panels.

𝑇=𝐿−23.45∗𝑐𝑜𝑠((360/365)∗(𝑑+10))

Variables:

  • T is the tilt angle (degrees)
  • L is the latitude of the location (degrees)
  • d is the day of the year (1 through 365)

To calculate the optimal tilt angle for solar panels, first find the latitude of the location. Then, multiply the cosine of the product of 360 divided by 365 and the day of the year plus 10 by 23.45. Subtract this result from the latitude to get the tilt angle.
