Quick Answer
A higher installation angle increases summer energy production by reducing shading and allowing for more direct sunlight to hit the solar panels.
The Impact of Installation Angle on Summer Energy Production
During the summer months, the sun’s angle in the sky is higher, and its rays are more direct. A higher installation angle of solar panels can maximize the amount of direct sunlight that hits the panels, resulting in increased energy production. A common rule of thumb is to install solar panels at an angle between 20-30 degrees to optimize energy production during the summer months.
Optimizing Installation Angle for Summer Energy Production
Research has shown that a 20-30 degree installation angle can increase summer energy production by up to 10-15% compared to a lower installation angle. For example, a 10 kW solar array installed at a 20 degree angle in the summer months may produce 10-12% more energy than the same array installed at a 10 degree angle. This is because the higher installation angle reduces shading from nearby objects and allows for more direct sunlight to hit the solar panels.
Practical Considerations for Installation Angle
When determining the installation angle for a solar array, it’s essential to consider the local climate and the array’s orientation. In areas with high summer temperatures and direct sunlight, a higher installation angle (20-30 degrees) may be beneficial. However, in areas with frequent shading or high winds, a lower installation angle may be more suitable. It’s also important to ensure that the installation angle is consistent across the entire array to maximize energy production and prevent uneven wear and tear on the solar panels.
