7. Warranty

7.1. We guarantee for the period of five years from the date of delivery that the goods were - in accordance with the respective state of the art at the time of the order - faultless in design, materials and craftsmanship unless otherwise stated below.

7.2. For solar light kits, we guarantee for the period of five years after date of delivery as above, if pole design, battery type, and earth-pit design have been approved by us before installation and local installation has been done according approval. Without approval or installation diverging from the approved method, we don't provide a warranty.

7.3. For batteries (accumulators) installed overground inside poles,we warrant as follow:
a. LiFePO4, moderate climates: five years.
b. LiFePO4, hot or cold climates: two years.
c. VRLA, moderate climates: one year.
d. VRLA, hot climates: no warranty.
Moderate climate specifies, that ambient air temperatures are
permanently in the range of minimum 5°C and maximum 35°C.

7.4. For batteries (accumulators) installed underground inside
earth-pits, we warrant as follow:
a. LiFePO4: five years.
b. VRLA: two years.

7.5. Warranty period of batteries starts with the date of delivery.

7.6. We do warrant for batteries only, if:
a. Batteries have been transported and stored properly before installation.
b. Pole or earth-pit design have been approved by us and are built according to our approval.

7.7. We do not warrant for electronics components and the functionality of the whole system, if third-party batteries are used without their previous approval and testing by us.

7.8. Normal wear and tear as well as force majeure, accidental damage and improper handling are excluded from the warranty.

7.9. Warranty claims shall be asserted in writing detailing the defects. The object of the complaint (part) shall be sent back by the client to our premises in Vienna at the cost of the client for inspection and/or repair. Parts which cannot be sent back to us (e.g. steel poles) have to be kept available for inspection.

7.10. We are free to decide either to repair defect parts or to provide a replacement (spare part).

7.11. Replacement deliveries (spare parts) as well as repaired parts will be provided ex works Vienna (EXW Vienna). Other expenses (transport costs) shall be borne by the client.

7.12. For warranty claims of batteries, we can either provide a replacement delivery ex works Vienna (EXW Vienna) or provide "pro rata" compensation payment(s).

7.13. The height of the "pro rata" compensation payment for batteries is calculated as follows: remaining days till end of warranty period times price of battery per day warranty period (price of battery per day warranty period equals to original battery price in € divided by number of warranty days).

7.14. Minor colour variations, colour variations which are a result of the use or the composition of different materials, as well as breakage and tears of the solar cells shall not be treated as deficiencies as all PV elements are tested before delivery.

7.15. Painting or powder coating of HDG steel poles may be done for externally visible surfaces only. Non-coating and surface treatment of surfaces not externally visible shall therefore not be treated as deficiency.

7.16. Deviations of components within tolerances, which are defined in the applicable norms and standards, shall not be treated as deficiencies.

7.17. Inconsistencies in subsequent deliveries regarding the light characteristics (flux, colour temperature, etc.) relative to preceding deliveries are possible due to technological progress and the usage-dependent change of the light flux and shall not be treated as deficiencies, provided that the
functioning of the system as a whole is not impaired.

7.18. The functionality of solar lights (particularly illumination strength, availability, etc.) highly depends on the conditions at the installation site. It shall not be considered a defect if, due to the conditions (light/shade, climate, air pollution, soiling of components) at the site, a product (solar light, etc.) provides a lower performance than that indicated by us for typical locations.

7.19. We shall not be liable for damages and/or accelerated aging of goods and our warranty is void in cases (not exclusively) such as:
a. Improper storage of goods before installation. Batteries shall not be stored at ambient temperatures below 5°C and above 30°C.

e. Installation of batteries in underground enclosures along with electronics equipment producing waste heat.
f.Improper foundations.
g. Improper interventions which have not been explicitly instructed or permitted by us, such as; opening of components, in addition to unauthorised attempts at repair.
