washer is used between the flat washer and the module frame (as shown in Figure 6). This washer is used to avoid
corrosion due to dissimilar metals. Tighten the screw securely to ensure positive electrical contact with the frame.

Partial shading of an individual module can cause a reverse voltage across the shaded module. Current is then forced go
through the shaded area by the other modules.
When a bypass diode is wired in parallel with the series string, the forced current will flow through the diode and bypass
the shaded SPV module, thereby minimizing module heating and array current losses.
Each Topray Solar crystalline solar module has a TÜV approved junction box with 3 to 6 bypass diodes already installed.
