Jolywood launches 615W TOPCon solar module and all-black panel for residential segment
The Chinese manufacturer has launched two new bifacial products based on its n-type TOPCon 2.0 cell technology. The JW-HD156N panel has a power output of 615W, a front side efficiency of 22% and is intended for utility scale projects. The second product, called JW-HD108N, is an all-black panel with a power rating of 425W, for the residential segment.
Viessmann and 50 Hertz integrate heat pumps to stabilize German grid
The partner companies say smart heat pumps can offer flexible capacity that network operators can use for safe operation and households could also benefit from a reduction in electricity prices.
State Grid of China switches on world’s largest pumped-hydro station
Located in China’s Hebei province, the 3.6GW facility consists of 12 reversible pump generating sets with a capacity of 300MW each and has a power generation capacity from storage of 6.612 billion kWh.
Bluetti launches sodium-ion solar generator
Bluetti’s NA300 sodium-ion solar generator offers thermal stability, fast-charging capacity, low-temperature performance, and integration efficiency.
Enphase enters EV charging market

PV-powered heat pump system for commercial swimming pool heating
Researchers in Jordan have designed a solar-assisted heat pump system for swimming pool heating at a hotel in the coastal city of Aqaba. They found that the system has a payback time of only 1.94 years and that total profits after ten years of operations may reach around $1.88 million.
Solar for polytunnel greenhouses
Israeli researchers have tested organic PV modules to power polytunnel greenhouses and have found that they might offer advantages over conventional crystalline silicon, despite their lower efficiency rates. They have lower operating temperatures but are subject to degradation, due to the mechanical stress caused by the wind-induced movement of tunnel sheeting.
Antimony selenosulfide solar cell with 10.7% efficiency
Scientists in China have developed a cell with an open-circuit voltage of 0.673 V, a short-circuit current of 23.7 mA per cm2, and a fill factor of 66.8%. They improved the quality of the antimony selenosulfide films by using alkali metal fluorides.
World’s largest floating PV plant goes online in China
Huaneng Power International has switched on a 320 MW floating PV array in China’s Shandong province. It deployed the plant in two phases on a reservoir near its 2.65 GW Dezhou thermal power station.
NASA telescope deploys solar array
NASA sent the world’s most powerful telescope into space on Dec. 25. It deployed and powered a related PV array 30 minutes after launch.
