The “Swiss” guarantee, branded by a Swiss producer in accordance with the strict norms of the nation, is 10 years on the product and 25 years on the power.

From the first year, the output of the module is guaranteed for a linear decline of nominal power of ≤ 0.8%/year, for 25 years. GEL > 80% guaranteed.
To assure reliability in the long term, other than carefully selecting materials, we periodically withdraw samples from the production line that have already been polymerized with EVA. The samples are then thoroughly chemically analyzed in order to verify that all products contain values of GEL no less than 80%. The indicating parameter of reliability in the long term for a module is the percentage of polymerization of the EVA capsule (content of GEL). SUNAGE guarantees GEL value of >80% whereby the standard is 65%.

Snowfall load max 5400 Pa equal to 540 Kg/m2. This guarantees the maximum resistance of the module under even the harshest climatic conditions. SUNAGE modules are also resistant to footfall and thereby facilitate maintenance. All the modules are checked with an electroluminescent visor in order to guarantee that each cell maintains the exceptionally high quality standards synonymous with SUNAGE.
