User manual SANYO HIT POWER 205A INSTALLATION

[. . . ] General Installation Manual © Jul 2010, Sanyo Electric Co. , Ltd. 7/13/10 General Installation Manual for SANYO ® HIT Photovoltaic Modules. Please read this manual carefully before installing or · using SANYO modules. This manual applies to the following HIT Power products: HIT Power 220A (HIT-N220A01) HIT Power 215A (HIT-N215A01) HIT Power 210A (HIT-N210A01) HIT Power 205A (HIT-N205A01) · INTRODUCTION Thank you for choosing SANYO HIT photovoltaic (PV) modules. [. . . ] Install modules so that air can circulate between the roof and the module. · Leave 1 inch of clearance between the roof and the module frame. If other mounting means are employed this may effect the temperature of the panel. · SANYO recommends the installation method and mounting profile shown in Figure 1. · A module should be attached on a mount or support structure rail by metal clamps. The metal clamp must fulfill the following specifications. Mounting Structure Rail Metal clamp A Size: not less than 1. 5" (38 mm) width Thickness: not less than 0. 12"(3 mm) Material: aluminum alloy bolt torque range: 16N. m to 20N. m. Operating Conditions SANYO requires that modules be operated within the following Operating Conditions: 1) Terrestrial applications only--no outer space or Special Conditions (see below). 2) 2) The ambient temperature must be within ­20°C (-4°F) to 46°C (115°F). The temperature limits are defined as the Monthly Average High or Low of the installation site. 3) The wind pressure load of the installation site should be less than 2 2, 880N/m (60PSF). 4) Some environmental conditions could apply. Please refer to Sanyo's warranty exclusions. measured at Standard Test Conditions (STC). STC conditions are; Irradiance o of 1000W/m, 25 C cell temperature, and solar spectral irradiance per IEC 60904-3. Note: At the time of shipment, Sanyo guarantees the output level of its modules to be -0/+10% against Rated Power in SPECIFICATIONS based on Sanyo's factory inspection at STC conditions. Under real conditions, a photovoltaic module may experience conditions that produce more current and/or voltage than reported at Standard Test Conditions. Therefore, Isc value of modules should be multiplied by a factor of 1. 25 to determine ampacity. An additional factor of 1. 25 may be required for sizing conductors, fuses, disconnects, etc. Please refer to section 690. 8 of the National Electrical Code (NEC) for guidelines. The Voc must be factored according to the lowest recorded ambient temperature recorded for the location where the modules will be installed. Please refer to section 690. 7 of the NEC for more information regarding voltage Solar Module Metal clamp B Solar Module Mounting Structure Rail M8 Bolt Metal clamp B Metal clamp A Module M8 Nut Mounting Structure End of Module M8 Nut M8 Bolt Between Modules Figure 1.

[. . . ] Conduit · In applications where wire raceways or conduit are used, follow the applicable codes for outdoor installations. · Verify that all fittings are properly installed to protect wires against damage and prevent moisture intrusion. DIODES Bypass Diodes · When modules in series strings are partially shaded, it may cause reverse voltage across cells or modules, because the current from other cells in the same series is forced to flow through the shaded area. This may cause undesirable heating to occur. [. . . ]
