Our warranty insurance solutions help to secure your sustainable business in the long run. Energy storage systems often involve the complex integration of multiple high-tech components. These are all prone to failure and malfunction, particularly over long periods of ten years and more.

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).

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.

Energy storage systems often involve the complex integration of multiple high-tech components. These are all prone to failure and malfunction, particularly over long periods of ten years and more. As a manufacturer and system integrator you have to provide your customers with warranties.

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.
