When a bypass diode is wired in parallel with the series string, the forced current will flow through the diode and bypass
the shaded module, thereby minimizing module heating and array current losses.
For 12-volt systems and higher: Each module junction box has a diagram illustrating the proper orientation of the
bypass diode installed between two of the terminal screws (Figure 11, Figure 12). When the solar modules are
connected as individual series strings first, and then these strings are connected in parallel, bypass diodes should be
used in each junction box. This is the simplest wiring arrangement for most installations.
Diodes that are used as bypass diodes must:

 Have a Rated Average Forward Current [I

F(AV)

Above

 maximum system current at highest module operating

temperature.

 

Have a Rated Repetitive Peak Reverse Voltage [V

RRM

Above

 maximum system voltage at lowest module

operating temperature.

12. MAINTENANCE

Kyocera modules are designed for long life and require very little maintenance.  Under most weather conditions, normal
rainfall is sufficient to keep the module glass surface clean. If dirt build-up becomes excessive, clean the glass surface
only with a soft cloth using mild detergent and water.  USE CAUTION WHEN CLEANING THE BACK SURFACE OF
THE MODULE TO AVOID PENETRATING THE PVF SHEET.  Modules that are mounted flat (0

°

tilt angle) should be

cleaned more often, as they will not "self  clean" as effectively as modules mounted at a 15

°

tilt or greater. Once a

year, check the tightness of terminal screws and the general condition of the wiring. Also,  check to be sure that
mounting hardware is tight. Loose connections will result in a damaged module or array.

13. SPECIFICATIONS

The electrical and physical specifications can be found at the end of this document (Table 2).

NOTES

  The electrical characteristics are within  

±

10 percent of indicated values of Isc, Voc, and Pmax under standard test

conditions (irradiance of 1KW/m

2

, AM 1.5 spectrum, and cell temperature of 25

).

 

 Under certain conditions, a photovoltaic module is likely to produce more current and / or voltage than reported at

standard test conditions. Accordingly, the values of Isc and Voc marked on this module should be multiplied by a
factor of 1.25 when determining component voltage ratings, conductor ampacities, fuse sizes, and sizes of
regulators which are connected to the PV output. Refer to Section 690-8 of the National Electrical Code for an
additional multiplying factor of 125 (80 per cent derating) which may also be applicable.
