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 …
