DIAGNOSTICS AND TROUBLESHOOTING
The strict quality controls in the factory ensure that Helios Solar Works modules are sold free of defects,
breakages and/or other problems. However, in its operation some problems may arise that can alter the
correct operation of the modules. They are detailed as follows:
Breaking of the glass. The tempered glass is resistant to impact; however poor handling during transport
or installation as well as excessive mechanical tension in the racking structure, or impact can break the
glass. Chipping of the surface might reduce the transparency of the module. Accumulation of dirt and
humidity between the spots might lead to freezing, increasing the separation of the frames. Regardless, the
module may continue producing power between 50 and 70 % of its capability – weather resistance will be
compromised though.
On occasion the seal of the junction box is compromised due to external conditions such as weathering.
Short-circuit of the module: An excess of intensity due to meteorological phenomena or mistakes in the
connection can cause damage, short-circuiting some of the bypass diodes contained in the module. As a
result, the voltage of the module will decline in proportion to the damaged diodes to 2/3, 1/3, or 0 V. Only
Helios Solar Works personnel are authorized to replace the bypass diodes.
Helios Solar Works guarantees the workmanship of its modules for ten years. In the event of accelerated
deterioration of the module, Helios Solar Works should be notified immediately to make the necessary
replacement.
