1. Introduction 1.
b) When stacking modules, it needs to be stacked neatly in the horizontal plane, under the condition of the glass facing down and the back way piled up, while the cardboard bedding need to be underside the modules. If the modules will be installed on the rooftop, the number of each stack is suggested no more than 20. In case of the poor load-bearing capacity, it’s recommended that each stack number is no more than 10.
2.2 Installation Safety 2.2.1 Wear protective head gear, insulating gloves, safety shoes, and insulated tools when installing the modules. 2.2.2 Do not install the modules in rain, snow, or otherwise wet or windy conditions. 2.2.3 Completely cover the PV module surface with an opaque material during PV module installation and wiring to prevent accidental charge buildup. 2.2.4 Plug in connectors tightly when working on wiring. 2.2.
3.1.2 Operating temperature: -40℃ to +85℃ 3.1.3 Mechanical load on panels (e.g., from wind or snow): less than 5400Pa 3.1.4 Tilt Angle selection: The installation should be facing north in the southern hemisphere and facing south in the northern hemisphere. 3.1.5 To maintain the modules’ Class C fire rating, the fire class of the roof and building materials should be higher than Class C. 3.1.
3.2.2 Clamping on the frame surface 3.2.2.1 Single glass module Modules can be laid either across the supporting bars (Figure d & f ) or parallel to the edge of frame (Figure e & g ) . (d) (e) (f ) (g) Remark: Illustrations (figure d、e、f、g) of the four different methods for clamping modules on the frame with aluminum clamps. “ means the aluminum clamp’s permissible clamping range.
To fasten the module: a) Place the module on the two supporting bars (not provided). The bars should be made with stainless material and treated with an anti-corrosion process (e.g., anodic oxidation treatment) or aluminum profile. Each solar PV module needs at least four clamps to fix. Do not make the clamp contact the glass directly or make the aluminum frame deformation in the installation process, and avoid the shadow of solar PV components.
(k) 4. Electrical Installation 4.1 Installation Condition 4.1.1 The electrical characteristics are within ±10% of the indicated values of Isc. Voc and Pmpp under the standard test conditions (irradiance of 1000 W/m2, AM1.5 spectrum, cell temperature of 25℃ . 4.1.2 The maximum system voltage of all the IEC & UL standard module series is 1000V. The 1500V standard products are also available according to the requirements）. 4.1.
Stainless steel M5 bolt Stainless steel M5 nut Stainless steel spring washer Stainless steel cut washer Stainless steel plain washer Copper wire Stainless steel M5 cup washer (k) Stainless steel M5 bolt (n) Grounding the aluminum frame with copper wire 4.2.1 The grounding requirements must be checked in accordance with the applicable regulations and standards before work is started. 4.2.2 Use the marked 5.5 mm grounding holes to ground the anodized frame.
b The period of the PV module cleaning shall be determined by the condition of the weather & pollution. O&M operator shall keep record of weather condition everyday with photo and data. 5.5 Condition of Cleaning 5.5.1 Use clean water or filtered water with soft type material (a sponge) to wipe the PV module. Never use chemicals on the surface of the module. 5.5.2 Cleaning after sunset or before sunrise is recommended for safety of O&M operator shock from heat stroke. 5.5.
