PV modules

Singaporean Prime Minister Lee Hsien Loong said earlier this year that the city-state needs to “innovate and use technology” to overcome its resource scarcity problem. With one of the world’s largest floating PV arrays now in operation, it appears to be drifting in the right direction.

InterContinental Energy and CWP Global have proposed the use of 50 GW of solar and wind to annually produce either 3.5 million tons of green hydrogen or 20 million tons of green ammonia. The proposal follows the Australian federal environment minister’s recent rejection of environmental approvals for the 26 GW Asia Renewable Energy Hub.

The German companies plan to combine their tools for project planning and battery systems via a new interface. They aim to simplify the work processes of planners and installers.

Scientists demonstrated a perovskite-silicon tandem cell that reached 27% conversion efficiency. Though higher tandem cell efficiencies have been achieved, this represents a big jump in efficiency for those utilizing n-i-p architecture, which previously had not surpassed 22%.

The A-4 and A-3 auctions saw the participation of a huge amount of solar, wind, hydroelectric, and biomass projects.

The clamps can be installed on artisanal seam sheet roofs or industrial system seam sheet roofs made of coated steel, aluminum and other materials.

The PV module relies on Jinko’s TOPCon mono cell technology, for which a record efficiency of 25.25% was announced in late May. TÜV Rheinland has confirmed the result.

At this year’s 2021 SNEC Expo, GCL System Integration, a part of the Golden Concord Group (hereinafter referred to as GCL), launched a series of new module products which echoed the horn of the returning of this old giant. The company suffered a lot on finance in past few years due to subsidy default from central government to its heavy PV plant assets. After a big sale of these PV plants since late 2018 to China state owned energy enterprises, the liabilities and financial costs was cut off greatly and, the company reloaded with no more burden and came back to the frontline again. pv magazine caught up with general manager Thomas Kun Zhang to see what’s in store for GCL going forward.

Saudi scientists have tested several cooling technologies for solar panels and have found that active techniques work better than passive ones under harsh climatic conditions. The most effective one consists of a system based on four heat pipes immersed in a box of liquid, as liquid bulk, integrated with the back of the solar panel.

Smart Power India, a unit of the Rockefeller Foundation, has supported the installation of 9.2 MW of renewables-based minigrids at more than 300 sites across India. Jaideep Mukherjee, CEO of SPI, recently spoke to pv magazine about the importance of minigrids and barriers to deployment.
