If damages are discovered, a joint and immediate inspection by the carrier and the consignee 

will  be  requested.  Damaged  material  shall  not  be  removed  from  the  receiving  location. 

Photographs of the damages must be taken.  

 

The sales representative will be notified of a damaged panel by noting the identification code 

and it will not be installed.  

 

If necessary, the product will be stored in its original packaging and in a dry and secure location. 

 

Care should be taken when opening the packaging to ensure that the products are not scratched 

and that the glass is not exposed to impacts.  

 

Solar  panels  should  always  be  handled  with  care  to  prevent  them  from  being  dropped  or 

dragged. Possible scratches on the glass and on the rear casing must be prevented.  

 

Objects must be prevented from falling onto the panel. 

 

No heavy objects should be placed on the panel. Do not step on it.   

 

The modules must be transported by two workers. The panel must not be grasped or lifted by 

the junction box or by the electrical cables.  

 

In general, all system components and accessories should be handled with care during storage, 

transport and installation.  

 

After installation, all packaging materials should be disposed of properly and in accordance with 

appropriate waste management requirements.  

 

When handling solar fluids (e.g. propylene glycol and corrosion inhibitors), contact with the skin 

or eyes must be avoided.  

 

During manipulation, long-sleeved loose fitting clothing, gloves and eye protection should be 

worn.  

 

Solar  fluids  can  reach  high  temperatures.  Special  care  should  be  taken  with  liquids  and  hot 

surfaces.  

 

The panel must not be left exposed to solar radiation when the solar circuit has been drained.  

 

Those that will be exposed and empty must be covered to avoid long term damage.  

 

A  thermal  dissipation  (thermal  discharge)  system,  including  all  necessary  components,  is 

mandatory, as the collectors must not operate at temperatures above 85°C. 

 

The solar circuit pipes must be electrically grounded and the panel must be protected against 

lightning according to local regulations.  

 

The manufacturer will not assume any responsibility for damages to the equipment resulting 

from negligent storage or handling.
