The consequences of the warranties offered by DualSun are insured for 10 years by an insurance contract with the company Chubb (via a subsequent 10-year warranty that covers all equipment sold by DualSun). This means that even in case of failure of DualSun, the named insurer could take over DualSun's insurances for a period of 10 years after failure. Chubb is the world's largest publicly traded P&C insurance company.


NB: Subsequent Coverage is the coverage that remains after a policy has been terminated. When the coverage is based on the victim's claim, the coverage normally terminates on the date the policy is terminated. However, the subsequent guarantee can be activated in the event of the insured's cessation of activity, in this case DualSun.


2. Photovoltaic performance warranty

Thanks to the quality of our materials, the rigorous control of our manufacturing processes and the aging tests carried out, DualSun can guarantee the electrical power supplied by its panels for 25 years.

The photovoltaic yield guarantee varies according to the product, please refer to the product data sheet.

As an example, on a FLASH 425 panel in Shingle technology, after 10 years of operation, we guarantee our panels an electrical power of 93.1% compared to their initial power. After 25 years, the power is guaranteed at 84.8%.


3. Labor support

When the product is defective, DualSun offers professionals a fixed labor charge.



For SPRING hybrid panels, the labor package is €500 for each technician visit for the removal and replacement of defective eligible products, subject to the activation of guarantees. DualSun also pays for the consumables needed to put the installation back into service, on presentation of the invoice (e.g. glycol).



For FLASH photovoltaic panels, the labor package is €200 for each technician visit and 25€ per defective panel for the removal and replacement of defective eligible products, subject to the activation of guarantees.
