PV Diode
A bypass diode, also known as a solar diode or continuation diode, is connected inside the PV module to provide AC power when the battery or panel is blocked or fails. The diode itself is simply a device that allows current to flow in one direction.
are designed to meet the growing demand for reliable and efficient solar energy solutions. With over three decades of experience and an annual production capacity of 6 billion semiconductor devices, we are committed to providing advanced components for the renewable energy sector.
How PV Diodes Work
PV diodes function as one-way valves for electric current within solar energy systems.
They are strategically placed in solar panels, inverters, and energy storage circuits to control current direction, prevent reverse flow, and protect sensitive components.
In a solar panel, each group of solar cells generates current when exposed to sunlight.
If one or more cells become shaded or damaged, they can cause a reverse bias, leading to hot-spot formation and reduced power output.
A bypass diode connected in parallel across these cells automatically conducts, rerouting current around the affected section to maintain consistent power generation.
In battery-connected or hybrid systems, blocking diodes are used in series to prevent current from flowing backward from the battery into the solar panel during nighttime or low-light conditions.
This protection ensures energy is stored safely and that the system operates efficiently.
