SOLON SE remains true to its quality strategy and extends the guarantee conditions for solar modules retroactively as of March 1, 2010. The SOLON performance guarantee lays out a five-stage guarantee service over 25 years, instead of the typical two-stage guarantee offered on the market. SOLON thus guarantees an output capacity of 95 percent for the first five years after the purchase of a solar module, 90 percent for ten years, 87 percent for 15 years, 83% for 20 years, and 80% for 25 years.
