effect), the diodes bypass the current generated by the non-shaded cells, thereby limiting module
heating and performance losses.
Bypass diodes are not overcurrent protection devices. Bypass diodes divert current from the cell
strings in the event of partial shading. The characteristics of these diodes:
Voltage rating – 50 V;
Current rating – 20 A.
5 Fire class rating
SoliTek SOLID module has been approved by the IEC fire test and achieved Flammability Class A. Fire
test was performed at the inclination of 127 mm per 300 mm (as prescribed in the point A.2.5 of IEC
61730-2).
6 Mechanical mounting
All mechanical pressure values indicated in this manual are design figures, this means that test values
are 1,5 times greater, for instance if the modules are declared to withstand 1600 Pa pressure, it
means they were tested at 2400 Pa pressure.
6.1 Mounting rails
Please observe the safety regulations and installation instructions included with the mounting rail. If
necessary please contact the supplier directly for further information.
The modules must be safely set onto the mounting rail. The whole rail supporting the photovoltaic
system must be strong enough to resist potential mechanical pressures caused either by wind or
snow, in accordance with local, regional and state safety (and other associated) standards.
Make sure that the mounting rail will not deform or affect the modules when it expands as a result
of thermal expansion.
