Each solar cell loses performance when being exposed to the sun. WINAICO modules are characterized by a very low degradation securing you a permanently stable yield. The use of high-quality raw materials ensures the low degradation of the nominal power of our modules, particularly at the beginning of the operating life. For this reason, we can offer a 25 year linear performance guarantee. In the first year, WINAICO guarantees a performance of at least 97% of the nominal power. In the following 24 years, WINAICO guarantees a maximum performance reduction of 0.7% of the nominal power per year. With this performance bond, WINAICO guarantees quality and performance from its own production and provides you with security in your investment.
Solar installations are significant investments for homeowners and businesses. However, external factors can impact the efficiency and output of these systems.
