New tech to recover pure silicon from end-of-life solar cells
An Indian research group has used three different chemicals instead of commonly used hydrofluoric acid to separate silicon from the cell. The technique is claimed to be able to deliver recycled silicon with a purity of up to 99.9984%.
Compressed-air storage for commercial applications
Israel-based Augwind has built its first 250 kW/1 MWh compressed air storage system for the collective community of Yahel, in the southern, desert part of the country. The commercial scale facility will be connected to a PV system and will be used for behind-the-meter services.
Hydrogen power generator for isolated areas, construction sites, events
Developed by French start-up EODev, the 100 kVa system is equipped with fuel cells manufactured by Toyota. The generator has a power of 110 kVA and its lifetime is guaranteed for 15,000 hours.
Australian prefabricated solar array manufacturer launches new modular solution
Sydney-based 5B has taken the wraps off a new generation of its re-deployable modular Maverick solar technology which it says is not only quicker and easier to install than the previous model but 30% more powerful.
Microgrid-forming PV microinverter from Enphase
The 97%-efficient device is said to be the most powerful PV microinverter developed by the company to date and is capable of forming a microgrid during a power outage. The U.S. manufacturer expects to ship the first products in December.
GAIL to build 4.5 tpd green hydrogen plant
India’s largest state-owned natural gas company is looking to buy a 10 MW electrolyzer to produce 4.5 tons of green hydrogen daily.
Solar farms prove to bee hives of economic activity
A new study from researchers at the universities of Lancaster and Reading in the UK has managed to quantify the economic boost provided by the symbiotic relationship between solar farms and honeybee hives.
Growing advantage for off-grid storage in grid-tied applications
Swiss-based Studer Innotec is launching a battery inverter which brings the advantages of the off-grid space to grid-tied installations in Europe. In this interview, Pierre-Olivier Moix, chief technology officer and board member at Studer Innotec, explains the differences to a standard energy home system, and some possible applications.
Green lending criteria could improve the performance of power discoms in India
A new report finds the current credit rating mechanism for power distribution companies in India is highly linked to their operational and financial performance. The report highlights the need to revise discom ratings to reflect their green mandates, decarbonization plans, and tariff implications to resolve the challenges of payables (and receivables).
JinkoSolar sets new record for n-type solar cell efficiency
Manufacturing giant JinkoSolar has set another world record for n-type solar cell efficiencies with its TOPCon technology, this time pushing to 25.4%. The new world record was confirmed by JET laboratories in Japan, and surpasses JinkoSolar’s previous record of 25.25% set back in May.
