Maintenance, Specifications | Kyocera KC-120-1 manual

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 [IF(AV)] Above maximum system current at highest module operating temperature.

・Have a Rated Repetitive Peak Reverse Voltage [VRRM] 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.

NOTES

・The electrical characteristics are within ±10 percent of indicated values of Isc, Voc, and Pmax under standard test conditions (irradiance of 1KW/m2, 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.
