Make Reputed


Type i) Terminal Box: Terminal Box is a part of a module from which output is taken. Each PV Module is provided with one bypass diode in the terminal box.

17 | P a g e

ii) Series Junction Box: One series junction box is provided for each mounting structure for taking out final output. A blocking diode to be connected in series with modules in the box. a) Blocking Diodes: These diodes are connected in series with string of PV modules and its functions are as follows: Prevent circulating current between PV module strings. Prevent reverse flow of current from battery through PV array during night and / or period of low insolation. b) Bypass Diodes: These diodes are connected in reverse direction (anode to negative of PV module and cathode to positive of PV module) across each PV module of the strings.

They have same current rating as that of blocking diodes and their operation is as follows: Under normal operating conditions, the bypass diodes are reverse biased and play no part. When any module in a series is shadowed, the current through the module is reduced. Under these circumstances, the PV module gets reverse biased leading to power dissipation across the module and reduction in output power of which is undesirable. Presence of bypass diode provides an alternative path to flow of current in the string (as the diode becomes forward biased when PV module gets reverse biased) and also limits dissipation by limiting the voltage across PV module. iii) Panel Junction Box: This is for paralleling various series junction boxes(SJB) outputs. Terminal Boxes are provided in the panel junction box for paralleling +ve & -ve electrical output from serial junction boxes. Single compression cable glands are used for all inlet outlet to ensure IP class 55 assembly. iv) Array Junction Box: This is for paralleling –ve outputs from the individual panel junction boxes. A bus bar is provided with suitable studs and lugs for paralleling –ve electrical outputs from panel junction boxes.
