As challenging as warranties are for battery energy storage system (BESS) owners and operators, it is possible for there to be more clarity. Look no further than how the automotive industry handles electric vehicle warranties. They are simple and flexible, typically covering time (usually eight years) and mileage (usually 100,000 miles).
They typically warrant that the BESS components remain free from defects3 and performance over the course of the warranty period (up to 15 years for long-term warranties), providing that certain operating conditions, usage patterns, and other warranty conditions are met.
Inflexible and complex, the warranty model for energy storage systems has failed to keep pace with rapid market growth, the authors argue. This is an extract of a feature article that originally appeared in Vol.41 of PV Tech Power, Solar Media’s quarterly journal covering the solar and storage industries.
Valentin Lorscheid and Dr. Kai-Philipp Kairies of ACCURE Battery Intelligence propose ways in which BESS warranties can be reformed as the industry matures. Inflexible and complex, the warranty model for energy storage systems has failed to keep pace with rapid market growth, the authors argue.
