Can solar trackers help minimize heat derating in summer?

Benefits of Solar Trackers in Summer

Solar trackers are designed to maximize energy production by adjusting the angle of the solar panels to follow the sun’s movement throughout the day. In summer, when the sun’s rays strike the panels directly, heat derating can be significant, leading to reduced energy production. By tilting the panels at an optimal angle, solar trackers can minimize the impact of direct sunlight and reduce the panel temperature, resulting in a more efficient energy production.

How Solar Trackers Help Minimize Heat Derating

Solar trackers use a combination of sensors and actuators to constantly adjust the panel angle to optimize energy production. By adjusting the panel angle, solar trackers can reduce the amount of direct sunlight that hits the panels, resulting in a cooler panel temperature. For example, a solar tracker can adjust the panel angle to 30% of its maximum angle in summer, reducing the panel temperature by up to 20°C (36°F) compared to a fixed tilt system. This reduced temperature can result in an increase of up to 15% in energy production.

Optimizing Solar Tracker Settings for Summer

To maximize the benefits of solar trackers in summer, it’s essential to optimize the tracker settings. This can be achieved by adjusting the tracker’s azimuth and altitude settings to account for the changing sun position throughout the day. Additionally, many modern solar trackers come with built-in algorithms that can automatically adjust the panel angle based on the current weather conditions and time of day. By optimizing the tracker settings, solar panel owners can ensure maximum energy production and minimize heat derating in summer. For example, a study has shown that a solar tracker with optimized settings can result in an increase of up to 20% in energy production compared to a fixed tilt system.
