The urgency to decarbonize the building sector has caught global attention in the lead-up to the COP26 summit, commencing on Oct. 31. Wood Mackenzie’s Ben Hertz-Shargel says that success will require a two-pronged strategy of massively electrifying building heat over the coming decade, while also investing in technologies that can pick up future heating demand if the grid cannot handle it.

Industrial shutdowns and reduced factory production capacity levels indicate the companies producing the raw materials used by solar manufacturers are being afflicted by electricity consumption measures just as other sectors are. It is not clear whether the solar industry will be afforded any favors by Beijing, as analyst Frank Haugwitz explains.

It turns out that you can have too much of a good thing, says Mark Byrne of Australia’s Total Environment Centre. Or rather, it’s possible that there is too much rooftop PV at some times in some places. As a result, a range of critical reforms – including the introduction of export tariffs to pay for upgrades of the electricity distribution network – are necessary to allow for the uninhibited growth of solar in the future, he argues.

With a rising chorus of voices calling for more solar industry recruits to perform the energy transition, Nigeria already has a skilled base of PV engineers and, with a little help filling the few gaps they have in their knowledge, the nation can step into the breach immediately, as Testimony Gabe-Oji, chief technology officer for Abuja-based installer Green Energy Spectrum, explains.

China is the largest residential PV market in the world, and this trend is only expected to strengthen in the next few years. By July 2021, China’s cumulative installed residential PV capacity had reached more than 30 GW, with a total of 1.864 million residential units hosting solar PV systems. IHS Markit’s Holly Hu looks behind these impressive numbers.

The latest global PV industry outlook published by trade group SolarPower Europe, has indicated tight supply of the solar panel raw material is expected to persist this year but the trade body said it would be unlikely to drive further price rises.

This week saw prices in the polysilicon segment, and further downstream, rise again, with no end in sign. National Energy Agency statistics show a slowdown in installations for the second consecutive month in September. Manufacturers, however, continue to purchase components and materials in the expectation that prices will rise even further.

New investments and partnerships announced this week see hydrogen projects developing across Europe, India, Asia and more. The current climate of high prices for natural gas has led one company to exclaim that green hydrogen is now competitive with its fossil fuel produced ‘grey’ counterpart, and research continues into optimizing hydrogen supply chains and smoothing its integration into the energy landscape.

Innovative solar wafer company Nexwafe has closed its latest financing round with €32 million. The round was lead by the Indian group Reliance, which contributed €25 million to the round. The Freiburg-based wafer manufacturer intends to use the funds to drive forward the production and commercialization of its kerfless PV wafers.

Participating companies and industry experts from Spain’s most recent renewable energy auction, including APPA, Anpier, and Fundación Renovables, share their thoughts with pv magazine on the results published this week, and what could be done better in future tenders.

A new report by IRENA and the International Labour Organization highlights the employment potential of an ambitious climate strategy and calls for comprehensive policies in support of a just energy transition.

Sydney-based 5B has taken the wraps off a new generation of its re-deployable modular Maverick solar technology which it says is not only quicker and easier to install than the previous model but 30% more powerful.

A collaboration between universities, nonprofits, and a geospatial mapper led to development of a highway solar evaluation tool.

Bangladesh has floated an international tender seeking engineering, procurement, construction and commissioning services for a 60-MW solar power plant in north-western Pabna district.

Norwegian hydropower giant and Europe’s largest renewable energy generator, Statkraft, has published its annual “Low Emissions Scenario”, which describes investment in green projects as “unstoppable”, while calling for a dramatic scaling up for renewables, electrification and green hydrogen.

Energy consultancy DNV was tasked by module manufacturing giant Longi Solar with comparing the balance of systems costs between modules utilizing 182mm and 210mm wafers, based on a 3.7 MW project in three different layouts. The results reveal a slim cost advantage for the smaller of the two, based on both fixed tilt and tracker systems.

Researchers at NREL and EPRI focused heavy bass sounds on solar panels to simulate the effects of wind-caused deflection.

The record efficiency was obtained thanks to an interlayer placed between the electron-transporting layer and the perovskite layer, which eliminated the need for passivation. The cell was also able to retain around 90% of its initial efficiency after 500 hours under standard illumination.

Scientists in South Korea demonstrated a fabrication technique for perovskite solar cells relying entirely on room temperature, ambient conditions processes. Using an all-inorganic perovskite material, and a spray coated electron transport layer, cells fabricated by the group achieved a maximum efficiency of 19.75%.

Underground hydrogen storage seems to be coming up a lot lately, and with the burgeoning hydrogen industry needing somewhere to store itself, it’s not hard to understand why. One of the countries with the best credentials for the future hydrogen economy is Australia. A newly published report has quantified the country’s “massive opportunity” for underground hydrogen storage.

Scientists in the United States developed a method to observe the structure and mechanics of a perovskite material during its synthesis and transition from liquid precursors to a solid thin film. The group says its work will provide new insight into manufacturing and the development of reliable large-scale processes for perovskite solar cell production.

Frédéric Dross of STS shares the minor yet essential details that buyers must pay close attention to when finalizing PV module purchase agreements, based on the company’s experience advising clients across the globe. Avoiding hidden traps in purchase agreements comes down to detailed contractual knowledge, fine print, and understanding common practices to bypass strict controls.

PV manufacturing giant Trina Solar says it has agreed with other industry players on a set of standard dimensions and other technical specifications for PV modules utilizing 210mm wafers – the largest currently available on the market. The manufacturer says it expects the China Photovoltaic Industry Association to formally release the standard before the end of October.
