The result was confirmed by Germany’s Institute for Solar Energy Research (ISFH).

Researchers in Finland have demonstrated the technical feasibility of an off-grid residential PV system combined with short-term battery storage and seasonal hydrogen storage. The proposed model is applicable only to northern climates, as higher levels of solar radiation in southern locations would mean a reduced need for seasonal storage. It was tested in an existing single-family house in Finland with a 21 kW rooftop array and a ground source 6 kW heat pump.

Cell metallization is getting a makeover. Some ‘rocking’ research projects spearheaded by Fraunhofer ISE are now set to introduce new printing methods that could deliver more than a doubling of throughput. There are hurdles to overcome across various process steps and on a materials basis, but initial results appear encouraging.

The selected applicants are required to execute projects across categories like solar-powered cold storage, solar water pumps, solar-powered reverse-osmosis water systems and off-grid solar systems for primary health care centers on a turnkey basis. The work includes engineering, supply, erection, commissioning along with maintenance support for three years.

The current developer-EPC model has increasingly turned to focus on quality over a two-year horizon. This contrasts with long-term owners who are focused on quality over the lifetime of their projects (20 to 40 years). With long-term owners now buying projects in the pre-construction phase, the current model looks set for disruption. Olivier Crepon, managing director at Skyray Engineering, reviews the emerging model of project development and explains how it will impact developers, EPCs, and third-party services and ultimately lead to a stronger, more mature PV sector.

Available in four different products, the series features a conversion efficiency of 20-21.2%. Two of the panels are packaged in a sleek, all-black aesthetic.

Researchers in Norway have mapped all cropland areas that were abandoned between 1992 and 2015 and found that the vast majority is suitable for PV and bioenergy deployment. Around 30% is located in Asia, followed by the Americas, with a 28% share, and Africa, with a percentage of 22%. Europe and Oceania had shares of 20% and 5%, respectively.

IHS Markit released a white paper in which the analyst outfit shared some predictions for the power electronics market. First and foremost, inverters will become smarter, and after some power outages in key markets, these devices are gearing up to take on more grid stabilizing tasks, which hitherto had been reserved for synchronous generators.

It is now a well-established trend. After the switch to larger wafer sizes played out in 2019, this year has seen virtually all of the biggest PV manufacturers introduce new modules in dimensions above the 2-meter mark, and with power ratings in excess of 500 W – in some cases, as high as 800 W. As these modules begin to roll off production lines in larger quantities, it’s vital to take a look at the challenges and opportunities they bring to system design, installation, and long-term operation.

Scientists in Germany evaluated multiple silicon cell concepts based on both cost and efficiency in serving as the bottom layer in a perovskite-silicon tandem cell. The study, based on both simulation and experimental work, outlines advantages to various approaches with the silicon cell and concludes that in almost every case, perovskite-silicon tandem cells have the potential to bring solar costs down below what could be achieved with silicon alone.
