Efficiency Of Solar Panels At Different Angles

Solar panel angle is another way of describing the vertical tilt of your pv system.

Efficiency of solar panels at different angles.

Depending on your location and roof pitch you re going to lose somewhere between 10 20 efficiency as a result of not having panels facing in a due north direction. You can visualize this by shining a flashlight on a piece of paper. The summer optimum tilt angle on the other hand will be 34 15 19. As the angle of the sunlight on a solar panel deviates from the perpendicular the solar panel power output decreases.

If you have the option to place the panels in more of a north east or north west direction it is recommended. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer. The solar panel angle can affect the amount of solar electricity you generate and is based on two factors. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.

The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. This is because the average intensity of the light incident on a flat surface area decreases as the angle decreases from 90 degrees. If it s standing upright perpendicular to the ground it is at a 90 angle. Factors that affect solar panel efficiency.

A comparison of data in two us cities has been completed to exhibit the importance of a solar pv array s tilt angle. When a solar system is level with the ground it has no tilt.
