Efficiency Of Solar Panels At Different Angles

As the angle of the sunlight on a solar panel deviates from the perpendicular the solar panel power output decreases.

Efficiency of solar panels at different angles.

The summer optimum tilt angle on the other hand will be 34 15 19. The highest efficiency solar panels on the market today can reach almost 23 percent efficiency. The average efficiency of solar panels falls between the 17 to 19 percent efficiency range. The solar panel angle can affect the amount of solar electricity you generate and is based on two factors.

If it s standing upright perpendicular to the ground it is at a 90 angle. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49. Factors that affect solar panel efficiency. The optimum tilt angle is calculated by adding 15 degrees to your latitude during winter and subtracting 15 degrees from your latitude during summer.

This is because the average intensity of the light incident on a flat surface area decreases as the angle decreases from 90 degrees. The effect of an array s tilt angle on solar pv energy output may be up to 20 compared to that of flat installations. When a solar system is level with the ground it has no tilt. A comparison of data in two us cities has been completed to exhibit the importance of a solar pv array s tilt angle.

If you have the option to place the panels in more of a north east or north west direction it is recommended. Solar panel angle is another way of describing the vertical tilt of your pv system.
