The SA circuitry is as follows:
- Number of wings: 2
- Number of panel per wing: 2
- Numbers of sections per panel: 2
- Number of strings in parallel per section: 6
- Number of SCA's in series per string : 22
Two redundant bleed resistors, each 20 kOhms per panel, achieve short circuit protection.
Each string includes one blocking diode.
By design, each cell provides a by pass diode.
