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.
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).
When issues surface months later, the commercial warranty may have expired, leaving the owner covering the replacement costs. Performance warranty: A performance warranty is a guarantee that the storage system will maintain specific performance standards over a longer period—often between 15-20 years.
For instance, most warranty conditions cap daily charge-discharge cycles to one or two, even though significant portions of annual revenue are generated during just a few high-demand days in some markets. As the industry shifts from contracted revenues to higher shares of merchant operation, such limitations become increasingly costly.
2. Reflect practical usage patterns: Given that BESS warranties often span 15 years or more, flexibility is essential. Owners and operators require warranties that support evolving usage profiles, especially as energy markets grow more complex.
