Energy storage is becoming an integral part of the solar PV ecosystem. While utility-scale battery storage remains the most visible segment, storage is also steadily finding its way into homes and commercial and industrial facilities. This shift was clearly reflected at SNEC 2026 and Intersolar Europe 2026. Storage products occupied a growing share of the two exhibitions, ranging from residential batteries and C&I cabinets to multi-megawatt utility-scale systems. Their expansion is also driving demand for associated power electronics and grid-connection equipment, including hybrid inverters, power conversion systems, transformers and switchgear. The TaiyangNews New Balance of System (BOS) Components 2026 report reviews the storage systems and power-electronic components presented at these leading solar exhibitions. Products from 74 companies are organized into 8 sections covering residential storage, utility-scale BESS, PCS and grid-connection equipment, C&I storage, multi-segment portfolios, battery cells and emerging chemistries, specialized and mobile applications, and projects, digital platforms and business models. This report completes TaiyangNews’ 3-part review of the products and technology trends presented at the leading solar exhibitions of 2026.
