Safety 1.1. General safety • Modules that fall under this application class may be used in system operation at more than 50V DC or 240W, where general contact access is anticipated. The module is considered to be in compliance with IEC 61215:2016 & 61730:2016 only when the modules are mounted in the manner specified by the mounting instructions below.
• Do not use mirrors, other magnifiers or artificially concentrated sunlight onto the • Always use fall protection equipment when working from heights of 6 feet (183cm) or above. Follow Occupational Safety and Health Act (OSHA) or local govern • Do not permit any part of the module(s) to be submerged or allow for constant water to soil the module(s) unless it's natural rain fall or periodic cleaning.
1.3. Installation safety • Any module without a frame (laminate) shall not be considered to comply with the requirements of IEC61215:2016&61730:2016 unless the module is mounted with hardware that has been tested and evaluated with the module under this standard or by a field Inspectioncertifying that the installed module complies with the requirements of IEC61215:2016&61730:2016.
• Under normal conditions, a photovoltaic module is likely to experience conditions that 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 current ratings, minimum factor of fuse sizes, and size of controls connected to the PV output.
Product Identification Each module has two labels providing the following information: 1. Nameplate: describes the product type; rated power, rated current, rated voltage, open circuit voltage, short circuit current, all as measured under standard test conditions; weight, dimensions etc.; the maximum system voltage is 1500 Volts DC. 2.
Mechanical installation 3.1. Selecting the location Select a suitable location for installing the modules. The modules should face south in northern latitudes and north in southern latitudes. For detailed information on the best installation angle, refer to standard solar photovoltaic installation guides or consult a reputable solar installer or systems integrator.
Provide adequate ventilation under the modules in conformity to your local regulations. A minimum distance of 10 cm between the roof plane and the frame of the module is generally recommended. Always observe the instructions and safety precautions included with the module support frames.

The module clamps must not come into contact with the front glass or deform the frame in any way. Avoid shading effects from the module clamps and insertion systems. Drainage holes in the module frame must not be closed or obscured by the clamps. 3.4.

The modules are installed horizontally in the square array, and the module line length: the length of the positive and negative lines is not less than 0.30 m. Recommended installation method of full cell solar module: The modules in PV array are recommended for portrait connecting, and cable length is not less than 0.7 m.

The modules are installed horizontally in the square array, and the module line length: the length of the positive and negative lines is not less than 0.30 m. The modules are installed vertically in the square array, and the module line length: the length of the positive and negative lines is not less than 1.4 m.
Electrical installation 4.1. General installation Any hardware used must be compatible with any other used material to avoid galvanic corrosion. Defects caused by corrosions void the warranty. It is not recommended to use modules with different configurations (grounding, wiring) in the same system.

When designing large modules arrays connected to a single inverter, always take into account the resulting isolation resistance (Riso), which decrease increasing the number of modules in the array. A too low Riso can results in inverter faults. Please refer to local regulations to determine the system wires size, type and temperature.
4.2. Grounding For grounding and bonding requirements, please refer to regional and national safety and electricity standards. If grounding is required, use a recommended connector type for the grounding wire. For grounding, this guide refers to module frame grounding. If grounding is required, make sure module frames (metal exposed to touch) are always grounded.

2) Use WEEB-DPF to bond solar modules to module mounting brackets (grounding part is tested to UL467) 3) Use WEEB-DPF to bond solar modules to module mounting brackets (grounding part is tested to UL467) Notice that WEEB teeth is positioned completely under the edge of the module frame. Recommend fastening torque is 20.5N-m/15 ft-lb.
Maintenance To ensure optimum module performance, München Solar recommends the following maintenance measures: • Clean the module minimum once a year or more often when required depending of the pollution. Remove all organic from the surface. Module with soiling or contamination a soft may reduce the power generation of the system.
