Learn how bypass diodes protect solar panels from shading effects and improve system efficiency.
Why Bypass Diode is Used in Solar Panel?
A bypass diode is a crucial component used in solar photovoltaic (PV) arrays to protect PV cells that are partially shaded from those that are fully exposed to sunlight within the same solar panel , especially in high-voltage series arrays . Solar photovoltaic panels are an excellent way to harness the sun's energy to produce electricity. Whether they're part of an off-grid system or roof-mounted in a grid-connected setup , they offer a wide range of power outputs, from small-scale milliwatts to large-scale megawatts , thanks to the modular nature of these panels. Photovoltaic Shading Photovoltaic cells are semiconductor devices that directly convert sunlight into electricity. These cells are linked together to form a solar array , generating power when exposed to direct sunlight. In theory, all panels in a solar array should experience the same conditions. However, environmental factors like temperature, humidity, positioning, and sunlight intensity can affect the overall performance …
