Product and Performance Guarantee.
As a premium manufacturer we grant a 10 year product guarantee1) for our solar modules as well as a five-stage performance guarantee, instead of the typical two-stage guarantee offered on the market. SOLON thus guarantees an output capacity of 95% for the first 5 years after the purchase of a solar module, 90% for 10 years, 87% for 15 years, 83% for 20 years and 80% for 25 years.
Consequently a SOLON customer has a claim to a guaranteed average output capacity of 87% for each module based on a service life of 25 years. These figures refer to the relevant minimum power output listed in the module data sheet.
