Energy Storage

California-based Apparent Inc. has unveiled a new water heater that can reportedly offset 100% of a home’s water heating cost. The system uses low-voltage DC electricity generated by conventional solar panels and a cloud based, machine learning platform that manages energy in real-time.

Swedish heat pump maker Aira unveils new battery energy storage system and inverter range for the residential market. Aira Power Hub inverters and Aira Power Store batteries are marketed as part of a whole home energy management system, initially launching in the United Kingdom and Italy with a German rollout to follow.

Brazil’s Ministry of Mines and Energy says it has opened public consultation for a 2026 battery storage auction to contract systems of at least 30 MW that can deliver four hours of power daily under 10-year agreements.

The Chinese manufacturer said the product line includes five models with outputs ranging from 25 kW to 50 kW, supporting charge and discharge currents of up to 150 A.

While solar modules and batteries have become icons of rapid progress, most energy models are still stuck in the past. A new global analysis shows that the cost of renewable energy has fallen far faster than expected. Solar PV, wind power, and battery technologies have already reached price levels that models once placed many decades ahead – a misplaced pessimism that risks misdirecting billions in climate investment and could distort long-term defossilization strategies.

The Chinese company says that its new ESA series is available with a hybrid inverter ranging from 3 kW to 10 kW and storage capacities of 5 kWh to 48 kWh. The IP66-rated product supports an MPPT current of up to 20 A on the PV side and allows 200% PV oversizing, according to the manufacturer.

Researchers in China developed a large-scale PV-thermal heat pump system using a liquid overfeed method that reportedly improves both thermal and electrical efficiency. Field tests showed up to a 4.81% boost in power generation and significantly reduced pressure losses compared to conventional systems.

Adani Group says it will install a 1,126 MW/3,530 MWh battery energy storage system (BESS) at its Khavda renewable complex, marking India’s largest and one of the world’s biggest single-site deployments.

The PPA price for pure photovoltaic projects has fallen by 20% over the past year, making such contracts less competitive. However, clear structures for bankable hybrid PPAs are now beginning to take shape, says Pieter van der Meulen, Senior Account Manager at LevelTen Energy, in an interview with pv magazine.

A key infrastructure asset at one of the world’s biggest batteries has reduced operations and delayed completion for more than six months, with few details made public regarding the critical asset.
