Germany deployed around 350 MW of new PV capacity in December alone. Its cumulative solar capacity reached 66.5 GW last year.
An international research group claims that raw materials and land availability do not present a real barrier for a global energy system with solar at its center. They said that forecasts for PV growth should not have their axis on utility-scale power plants and instead consider vertical PV, agrivoltaics, and floating PV as the source of future big market volumes.
Sun Cable, the company behind the world’s largest solar and storage project, has officially gone up for sale after entering voluntary administration in Australia in January. Its administrator, FTI Consulting, is seeking binding offers of acquisition or recapitalization by the end of April, with a deal to be finalized by the end of May.
Canadian Solar says its cell and module capacity will reach 50 GW by the end of this year.
US scientists have applied bandgap gradient to a cadmium telluride PV cell for the first time. The result is an improvement of its efficiency and open-circuit voltage, and lower non-radiative recombination.
Japan’s largest oil company, Eneos, has opened a green hydrogen demonstration plant in Brisbane, Australia. The project is relatively small, producing just 20 kilograms of green hydrogen per day, but Eneos Senior Vice President Yuichiro Fujiyama says the company will expand it in the “near future.”
LG has developed an air source heat pump with the capacity to heat 200 liters to 270 liters of domestic water. It uses R134a as a refrigerant and the pump has a coefficient of performance (COP) of up to 3.85.

General Electric has switched on two more 300 MW pumped storage turbines at a 1.2 GW hydro battery complex in China’s Anhui province, after finalizing the facility’s first 600 MW unit in December. The project has completed a trial period and commercial operations are now fully underway.
Soleis AG has developed two storage systems with capacities of 1 KWh and 2 kWh.
Low participation rates for vehicle-to-grid (V2G) tech of just 12% to 43% are needed to provide short-term grid storage demand throughout the world by as early as 2030, according to a group of Dutch and US researchers.
H2i Technology has developed a hydrogen enhancement kit that injects hydrogen into existing diesel engines to reduce diesel use. It is building 10 commercial-ready systems and plans to soon start field testing.
V-Tac’s new 10 kWh lithium iron phosphate, wall-mounting battery system purportedly runs for more than 5,000 cycles.
Indian researchers have presented a new way to develop effective electrode materials for superpower redox flow battery (RFB) systems. Their flow cell with heat-treated nickel-rich platinum-nickel coating on the graphite felt delivered an impressive ever-best power density of around 1,550 mW cm−2.
US researchers have conducted case studies on the successful deployment of distributed renewables in the state of Alaska. In one study, two cities installed 223.5 kW solar PV arrays coupled with 351 kWh batteries and 250 kW inverters, in addition to cold climate heat pumps.

Katek, a German PV inverter manufacturer, says its 4.6 kW coolcept fleX inverter features silicon carbide (SiC) semiconductors from US-based Navitas Semiconductor. It is smaller and weighs less than non-SiC models.
Swiss scientists have used a minimal amount of silver to alloy the absorber in a thin-film CIGS solar cell. They say this process could help to improve efficiency, open-circuit voltage, and fill factor, while compensating for the low bandgap of the CIGS layer.
