How do I find the right solar power storage system for my application? This question is asked by many potential buyers. Battery storage systems available on the market differ considerably in terms of safety, price, performance, and hence, economic efficiency. New research shows how efficient batteries should be designed and provide information on the reliable assessment of the performance of storage systems.

Solar power storage systems differ considerably! Even when focusing on a single technology, such as lithium-ion technology, major differences remain.The efficiency of a complete system is determined by the whole chain from the solar generator to the battery, inclusive of the battery inverter, to the consumer. It is not only important to use highly efficient lithium-ion cells, but also to dimension the overall system adequately for the specific application. An optimum system efficiency is achieved, if the performances of the individual components are adjusted precisely. Apart from system architecture, battery efficiency is influenced by the cell and battery module connection technologies.
