Microinverters: Do They Offer Better Performance For Shaded Areas?

How Microinverters Work in Shaded Areas

Microinverters are designed to monitor and optimize the performance of each solar panel in a string, allowing them to adjust their output based on the specific conditions of that panel. In a shaded area, one or more panels may be producing less electricity due to the reduced sunlight. A microinverter can adjust its output to match the performance of the shaded panel, minimizing the overall impact on the system’s energy production.

Benefits of Microinverters in Shaded Areas

Studies have shown that microinverters can increase energy production by up to 25% in shaded areas compared to traditional string inverters. This is because microinverters can isolate the shaded panel and continue to produce electricity, rather than shutting down the entire string. For example, if a 5-panel string is partially shaded, a microinverter can optimize the performance of the unshaded panels, producing up to 90% of the system’s potential energy.

Comparison to Traditional String Inverters

Traditional string inverters, on the other hand, are designed to monitor and optimize the performance of the entire string. If one panel is shaded, the entire string may be shut down, resulting in reduced energy production. In contrast, microinverters can continue to produce electricity even if one or more panels are shaded, making them a better option for systems with complex shading patterns or areas with frequent tree coverage.
