Energy Storage

As off-grid solar systems expand to serve remote and underserved communities worldwide, digitalization has become a crucial need for efficient project development, implementation, and long-term sustainability. A new report from IEA PVPS Task 18 systematically explores digital tools across the entire off-grid energy project value chain, providing much-needed guidance for practitioners looking to optimize their operations.

Longi has reportedly acquired a stake in Suzhou Jingkong Energy, signaling a strategic push into energy storage amid rising profit pressures and heightened competition in the solar sector.

Preliminary results from the fourth renewables auction in the Philippines show 9.4 GW in awarded solar, wind and storage projects, short of the 10.6 GW target, with remaining capacity in floating solar and solar-plus-storage to be reassigned to qualified bidders.

China-based battery storage specialist Poweroad is rapidly expanding its global footprint, deploying advanced battery energy storage systems (BESS) even in some of the world’s most extreme climates, where temperatures can plunge to -40°C.

The Medlink Renewable Generation project, a collaboration between Italy, Algeria and Tunisia, will deploy 10 GW of renewables in the two north African countries for both local use and export.

Canadian Solar’s e-STORAGE unit has unveiled its FlexBank 1.0 modular utility-scale battery, offering 8.36 MWh per unit, with deployment expected in 2026.

Chile has emerged as a world leader in hybrid systems and standalone energy storage since implementing its Renewable Energy Storage and Electromobility Act in 2022. Ensuring projects are paid for injecting power into the grid during peak periods has supported growth, and ambitious battery energy storage system (BESS) targets are now being pursued to tackle curtailment.

Experts from Fonte Solar, Huawei, and Greener have exchanged solar-plus-storage tips, insights, and case studies at the invitation of pv magazine. In a panel at Intersolar South America 2025, they highlighted the need to understand consumption profiles and customer needs, as well as the technology’s limitations and potential.

The Estonian home and commercial storage systems come in low- and high-voltage models. The high-voltage option can scale to ten modules, for 100.8 kWh, and a six-module, low-voltage version to 45 kWh.

At Intersolar 2025, Sungrow’s Brazil country manager, Rafael Ribeiro, told pv magazine Brasil the company submitted more than 80 proposals to supply battery energy storage systems (BESS) between January and June alone, to projects interested in participating in the Leilão de Reserva de Capacidade na Forma de Potência (LRCAP) auction for battery storage.
