What diodes should be installed for solar power generation
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
To avoid reverse current under partial shading condition or block out of any PV cell, a diode is connected in S known as blocking diode, with each PV string. Since in this configuration, only one set of a control unit is used (comprising sensors and a monitoring unit), it is fruitful for a large-scale application (up to 30 kW) from an economic point of view.
