SAFETY AND INSTALLATION MANUAL FOR PHOTOVOLTAIC MODULES 1. General Information 4. Limited Warranty The photovoltaic (PV) modules Silfab SLAXXXM3A/SLAXXXM, SLAXXXP3A/SLAXXXP (‘SLA’); SSAXXXM, SSAXXXP (‘SSA’); SLGXXXM3G/ SLGXXXM, SLGXXXP3G/SLGXXXP (‘SLG’); and SSGXXXM, SSGXXXP (‘SSG’) are devices that produce electrical energy by converting the sunlight’s radiation reaching their surface, when appropriately exposed, into continuous/direct current (DC).
SAFETY AND INSTALLATION MANUAL FOR PHOTOVOLTAIC MODULES from sunlight, or by fully covering their front surface with cloth, cardboard, or other completely opaque non-marking material, or by working with them face down on a smooth, flat surface. are exposed to a light intensity that is less than 400W/m2 as measured by an accurate solarmeter/pyranometer.
SAFETY AND INSTALLATION MANUAL FOR PHOTOVOLTAIC MODULES (horizontal) configuration. Refer to Fig. 4b,c,d for an example of attaching the modules to a support structure using mounting clamps. Use stainless steel hardware. Avoid low tilt angles to prevent the accumulation of dirt/debris along the module edge. Modules must be spaced a minimum of 10mm apart on all sides to provide space for thermal expansion and to provide ventilation.

Fig. 5b: allowed positions for fixing SLG/SSG modules using mounting clamps. ATTENTION: in the case of installation with modules in the portrait configuration, install the modules with the junction boxes at the top in their “upright” position. This will reduce the risk of water infiltration into the junction box. 7 © 2011-2015 Silfab Solar Inc.
SAFETY AND INSTALLATION MANUAL FOR PHOTOVOLTAIC MODULES 7b) Handling of Modules 7c) Electrical Connection Do not connect or disconnect modules under load! Danger! Risk of serious injury or death from electric shock or electric arc flash! The Silfab modules are robust, but in particular the cells may be subject to damage if the modules are improperly handled or installed. High hazardous voltage (several hundreds of volts) may occur during installation.
SAFETY AND INSTALLATION MANUAL FOR PHOTOVOLTAIC MODULES The recommended maximum series/parallel configurations (for 1000V Maximum Series Voltage) are as follows: Modules in Modules in Product Series* Parallel SLA-M SSA-M SLA-P SSA-P SLG-M SSG-M SLG-P SSG-P 20 23 20 24 16 19 17 19 Refer to the tables at the end of this installation manual for electrical parameters.
SAFETY AND INSTALLATION MANUAL FOR PHOTOVOLTAIC MODULES For more information on the Tigo Optimizer System please contact Tigo Energy at: SLA/SLG modules can be grounded using third party grounding devices as long as they are certified for their intended purpose, have been evaluated and tested with the system, and the devices are installed according to the requirements of American NFPA NEC 70, Canadian CSA C22.1 and/or relevant local codes and regulations.
SAFETY AND INSTALLATION MANUAL FOR PHOTOVOLTAIC MODULES 8. Maintenance 9. Packaging, Handling & Storage Although PV modules do not require any routine maintenance, periodic (annual) inspection for damage to glass and inspection of the electrical connections and for corrosion as well as the mechanical connection is recommended. 9a) Silfab's Packaging These modules are arranged in a horizontal position with the glass facing downwards as shown in Fig. 6.
SAFETY AND INSTALLATION MANUAL FOR PHOTOVOLTAIC MODULES 9b) Correct Handling of Module Packaging Each package has been designed for safe shipment and storage of modules. The following symbols apply to the packing, with the following meanings: RECYCLE WHERE POSSIBLE: Both modules and packaging contain recyclable materials. Use caution when dealing with damaged modules.
SAFETY AND INSTALLATION MANUAL FOR PHOTOVOLTAIC MODULES 9c) How to Handle the Pallet During the handling of the pallet make sure to pay the utmost attention. The packaging must be raised/moved exclusively with fork-lift trucks or hand pallet trucks fitted with forks of length appropriate to its size and weight. The pallet which supports the packaging is a "4 ways" type (able to be lifted from any of the short or long sides).
