NTPC invites proposals for solarization projects in ISA member countries

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 long read: Disrupting developments

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.

Panasonic launches module series compatible with its Evervolt battery

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.

The world has 53 million hectares of abandoned cropland suitable for solar PV deployment

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.

The future of power electronics is distributed, aggregated and service oriented

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.

The long read: Bigger yes, but better…?

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.

Evaluating tandem cells, from the bottom up

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.

The market for hybrid energy and storage

“Efficient and economically viable energy storage, and optimal hybridization, are crucial for ensuring the expansion of renewable power generation both at the grid and micro-grid scale,” says Deepak Thakur, chief executive officer for the hybrid and energy storage business of Sterling and Wilson. He has spoken to pv magazine about the accelerated proliferation of renewables-plus-storage across markets.
