US scientists have utilized a nanochannels device to cool down the operating temperature of a commercial PV module and have found that the proposed technique is able to improve power yield by up to 32.8%. Spray droplets are dispersed over the nanochannels device in order to eliminate the need for a continuous supply of a coolant.

or some developers of ground-mounted PV, bifacial modules are already the default technology. The slight cost increase is often outweighed by an increase in energy yield. And yet “agreeing” on the right energy yield of a PV plant has always been the most heated debate between developers, investors, lenders, and technical advisers. Everoze partner Christophe Campistron looks at both sides.

Supply demand mismatch is the most crucial factor which is directly or indirectly leading to an increase in module prices. At present, demand (especially for poly-Si) far outstrips the supply. A balance between the supply and demand is essential for stabilization of solar module prices.

A new report from IEEFA says green ammonia could help India significantly reduce its trillion-rupee fertilizer subsidy bill and cut dependence on liquefied natural gas (LNG) imports for fertilizer production. The report looks at leading green hydrogen to green ammonia projects worldwide and reviews the cost competitiveness of producing green ammonia using various electricity inputs – grid electricity, round-the-clock renewable power, and solar power plus batteries. It also looks at the policy interventions required for green hydrogen and ammonia projects.  

Japanese glass manufacturer AGC has developed a building-integrated PV (BIPV) panel for different building requirements. It can be installed on facades, canopies, and curtain walls where normal glass can be placed.

Nitin Gupta, chief executive officer and co-founder, Attero Recycling, speaks to pv magazine about the supply chain concerns for lithium battery storage manufacturing in India, current battery recycling scenario and Attero’s capacity.

The solar manufacturer, with a 3.5GW cell and module production capacity, has expanded its retail sales footprint to Tamil Nadu with Festa Solar as the official distribution partner for the region. 

The new product relies on 23.4%-efficient solar cells and features a short-circuit current of 10.8 A. It can be folded into a briefcase and is claimed to be an ideal solution for camping and outdoor activities.

New research has categorized all existing fault detection and localization strategies for grid-connected PV inverters. The overview also provides a classification of various component failure modes and their potential causes in a tabular form.

While ALMM does support domestic manufacturers, this is not a sustained solution considering the wide demand-supply gap. Disincentivising imports could be a workable strategy when there is enough capacity back home.
