Quick Answer
Shading on a solar array reduces the amount of sunlight that can be converted into electricity, resulting in decreased energy production and potentially significant losses.
Understanding Shading Effects
Shading on a solar array can have a dramatic impact on its performance. Even partial shading can significantly reduce energy production, with losses ranging from 10% to 30% or more, depending on the extent of the shading. For example, if a 1 kW solar array is shaded by 20%, its energy output could be reduced by up to 200 watts.
Mitigating Shading Effects with Array Design
When designing a solar array for a ground mount, it’s essential to consider potential shading sources and take steps to minimize their impact. This may involve tilting the panels to optimize energy production, using a wider array layout to reduce shading between panels, or employing tracking systems to follow the sun’s movement throughout the day. By incorporating these strategies, you can minimize the effects of shading and maximize your solar array’s energy output.
