The 41 MW facility was built by Korean developer Scotra with solar modules provided by South Korea-based manufacturer Hanwha Q-Cells. It was deployed on a water reservoir at the Hapcheon dam, in the South Gyeongsang province.

Developed by a spin-off of Dutch research institute TNO, the battery is claimed to offer higher energy density, longer lifespan and increased safety compared to conventional lithium-ion batteries. It will initially be applied in wearables and electric cars.

Developed by a U.S.-based start-up, the new manufacturing process is claimed to reduce silver consumption and improve solar module performance by up to 3 watts. It consists of connecting sub-cells in series within a single cell in order to increase the device voltage and without requiring cells to be physically broken and rewired.

According to Chinese researchers, using abandoned coal mine goaves for pumped hydro facilities in combination with large scale solar and wind is not only technically feasible but can also provide an efficiency of 82.8% in yearly operation cases. They applied the model to wind and solar-rich northwestern and southwestern China.

Japanese energy company Sinanen offers a scalable solar carport that can host a minimum of four vehicles and can be deployed in the parking areas of factories and commercial buildings. The basic system is offered with a minimum capacity of 10.80 kW.

The battery was fabricated by Chinese scientists with a low-cost electrolyte made of a derivative of TEMPO, which is a well-known electroactive aminoxyl radical used with several applications in chemistry and biochemistry. According to the researchers, the battery shows high redox potential and is crossover-free.

In a new report, experts from the International Energy Agency Photovoltaic Power System Programme (IEA-PVPS) have assessed the economical and environmental benefits of repairing and reusing or replacing solar modules that are not complying with a 30-year expected lifetime. They found that reusing offers the best environmental impact in all cases, while the profitability of this option is currently guaranteed only by rooftop PV under certain conditions. As for large-scale solar, module replacement remains the most competitive option.

French energy giant Engie has developed a transfer function method based on a model used to assess PV plant variability. Its researchers claim that the new approach does not overestimate the levelised cost of hydrogen (LCOH) of an alkaline electrolyser powered by offgrid solar, finding that in Australia green hydrogen produced with such systems may already be cost competitive with blue hydrogen.

Scientists in Brazil have found that photovoltaic modules may be a repository of specialised microbes in tropical regions. According to them, these micro-organisms may be used in sunscreens, pigments for processed foods, chemicals, textiles, pharmaceuticals, and cosmetics.

The US battery manufacturer entered the stationary storage business with a new product for residential customers. The lithium iron phosphate (LFP) battery is compatible with new or existing PV systems.
