In a move that many other PV module manufacturers are expected to adopt, SolarWorld is the first manufacturer to switch to a linear performance guarantee on its entire range of solar modules. SolarWorld claims that as a result of the change, it has extended the performance warranty for its modules from two to five years. Traditionally, the industry has used a stepped performance guarantee system, such as 90% of the lower nominal output for the first 10 years and then 80% for year 11n onwards.

The linear guarantee from SolarWorld includes a first year of operation guarantee of at least 97% of the nominal output, with the second year of operation declining by no more than 0.7% of the nominal output. In the 25th year of operation, the module would have an actual performance of at least 80.2% of the nominal output.
