corrosion. ・ The solar module frame must be attached to a support structure using ¼” or M6 stainless steel hardware in a minimum of four (4) places symmetrical on the solar module. The stainless steel hardware used for securing the module frame should secured with an applied torque of 6 foot-pounds (8 Newton-meters). ・ Module support structures that are to be used to support Kyocera Solar modules should be wind rated and approved for use by the appropriate local and civil codes prior to installa

7. INSTALLING KC MODULES The frame of each module has 0.28” φ diameter (7 mm) mounting holes (Refer to Module Mounting Specifications). These are used to secure the modules to the supporting structure. An example of a ground mounted structure is shown in Figure 3. The four holes close to the corners of the module are most often used for attachment. Refer to the Mounting Specification Specifications for the position of these holes. Clearance between the module frame and the mounting surface may b

C. The wire used to interconnect the solar modules may be single or two conductor, from 14 AWG (2.08 TERMINAL SCREW 2 2 mm ) up to 10 AWG (5.26 mm ) gauge stranded copper wire, in a “SUNLIGHT RESISTANT” jacket SPRING WASHER UF cable. This cable is suitable for applications CABLE where wiring is exposed to the direct rays of the sun. The maximum and minimum outer diameters CUP WASHER of the cable that may be used with the cable connector are 8 mm and 6 mm respectively (Fig. 3). D. Using a flat bl

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 co
