A Slovakian startup has developed a photovoltaic-integrated arm that provides off-grid power for weeding and other small agricultural applications. In its largest configuration, the system is 18 meters long, has a capacity of 2.4 kW, and is able to cover a cultivated area of 994 m².

The battery has a rated output of 5.5 kW and can be installed in outdoor environments. It is equipped with a hybrid power conditioner, a DC-to-DC converter, and a vehicle power supply adapter with a maximum output of 1.1 kWh.

Advanced solar panels, inverters, batteries and plant monitoring technologies are revolutionizing the solar sector.

Renewables developer Acme Cleantech Solutions has signed a deal with the Karnataka government to invest INR 52,000 crore ($6.7 billion) in a new plant capable of producing 1.2 million tons of green hydrogen and ammonia per year, co-located with a captive solar plant.

The new prototype uses a triple-junction compound design, which sandwiches the solar cell between layers of film. The module is expected to be used in a variety of vehicles, an application that demands high efficiency and lightweight construction. Its conversion efficiency bests that of a similar Sharp module developed in 2016, which notched an efficiency of 31.17%, at the time a world record.

While many solar manufacturers are as yet undecided about which PV cell technology they will choose for their next high efficiency expansions, for Singapore-based REC, the future is HJT. pv magazine spoke to Cemil Seber, the managing director at REC Solar EMEA GmbH at the Intersolar Europe 2022 trade show, to dig deeper into these manufacturing plans.

The Delhi-based renewable project consultant aims to expand electrolyzer production capacity to 1 GW after its initial 250 MW is operational. It is also looking at offering turnkey solutions for green hydrogen plants and the production of high-pressure tanks and cryogenic vessels for hydrogen storage.

US scientists have come up with an analytical way to evaluate the costs and net value of different configurations of large-scale wind and solar projects paired with battery storage. They identified six trends in the US electricity market and found that their framework is aligned with current commercial practices.

Aurora Energy Research says in a new report that maximum green hydrogen project profitability could be achieved when solar and wind power plants are combined with electrolyzers.

Sharp’s new 375 W solar panels feature multi-wire technology, with a power conversion efficiency of 20.4%.
