9 Warranties 

 

Warranty conditions for Wikora flat plate collectors.  All deliveries and services are carried out according to 
our general terms and conditions. 

 

1. 

The warranty period for the collector function amounts to 

10 years.

 Within that period, all parts proven to be useless or 

considerably  reduced  in  their  usability  due  to  production  or  material  defects  are  repaired  or  replaced  ex  works.  At 
expiration of the legal warranty period, we have the choice between rectification or replacement. 

 

2. 

The  warranty  begins  with  the  delivery  of  the  collectors  to  the  end  user  and  under  condition  that  the  system  has  been 
installed  and  setup  by  a  specialised  company  according  to  our  installation  and  operating  instructions  as  well  as  the 
locally  valid  norms  and  regulations.    Further,  the  warranty  is  dependent  on  a  carefully  completed  installation  and 
maintenance record which must be filled out by the installer and kept by the system owner.  

 

3. 

The guaranteeing implies that 

  the  collectors  are  transported,  installed,  operated  and  maintained  according  to  our  installation  and  operating 

instructions 

  the collector system is exclusively operated with our solar liquid. 

 

4. 

The guaranteeing does not refer to dammages due to  

  wear and tear, excessive wear, inappropriate operation or inappropriate use, 

  use of a unsuitable solar fluid or results of corrosion provoced by a solar fluid, 

  chemical or electro-chemical influences, 

  incorrect system layout. 

 

5. 

 Moreover, the warranty does not apply for 

   damages as a result of an inappropriate storage of the collectors prior to installation and 

   damages that are ascribed to force majeure, 

  The warranty regarding the safety glass refers to its condition, and here only to manufacturing and material defects.  

The  cullet  security  is  examined  in  the  context  of  the  inspection  requirements  for  collectors  and  ensured  only 
according to these requirements.  

 

6. 

  The warranty expires 

  if  arising  and  obvious  defects  are  not  notified  in  writing  within  10  days  after  receipt or hidden defects immediately 

after emerging. In case of hidden defects it is only valid for the warranty exceeding the legal warranty period, 

  if the collectors are changed or maintained by non-spezialised persons or companies or undertaken without our prior 

agreement,  

  if the possibility to peer the entire system is not granted or if the collectors are removed without our agreement, 

  if  original  Wikora  components  are  exchanged  by  other  components  or  if  inappropriate  installation  material  and 

system components as well as nonauthorized solar fluid are used, 

  if  the  annual  inspection  is  not  realized  within  the  time  limit.  The  proper  execution  is  to  be  documented  by  the 

specialized company in charge.   

 

7. 

Transport  damages  are  to  be  notified  immediately,  stipulated  on  the  delivery  note  and  signed  by  the  sub-contractor. 
§447b BGB remains untouched.  

 

8. 

After  the  expiration  of  the  legal  warranty  period,  the  warrantee  must  provide  the  necessary  aide  in  case  of  reparation 
work  and  is  obliged  to  assume  the  necessary  services  like  transport,  installation  etc.  In  the  event  of  warranty,  we 
recompense  

   for  on-roof  installation  max.  200,00  €  +  VAT  for    the  first  collector  and  max  80,00  €  +  VAT  for  each  additional 

collector, incl. all consumables.  

   for in-roof installation max 300.00 € + VAT fort he first collector and max. 90.00 € + VAT for each additional collector, 

incl. all consumables.  

 

9. 

This warranty does not justify claims exceeding the legal liability for physical or personal injuries that have been caused 
by the defects of the purchased object.  Redhibitory actions and abatements exceeding legal regulations are not justified 
either.  

 

10. 

Other legal claims for warranty and damages in respect of BGB and ProdHaftG remain untouched by this warranty.  

 

11. 

The exchange or rectification of the collectors or other parts of the solar system must be carried out by the installer and 
only after having consulted Wikora.  Otherwise an entitlement to compensation does not exists.  

 

12. 

Notifications  of  claim  are  to  be  announced  in  writing    to  WIKORA  GmbH  and  by  presenting  the  installation  and 
maintenance record as well as the respective proofs immediately after the damage is occurred.  

 

13. 

Solar accessories are subject to the legal warranty.
