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.

A note issued by Norwegian analyst Rystad has hinted it may be time to consider abandoning the 1.5-degree average global temperature rise ceiling agreed upon in Paris six years ago, because the world will never be able to pump out enough solar panels in time.

An independent third-party has approved the European Commission’s safeguards to ensure the projects in member states financed by €250 billion of green bonds over the next five years, will have genuine emission reduction credentials.

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.

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.

Research from the U.S. National Renewable Energy Laboratory shows that high-renewables operation is possible, and less expensive, when a range of energy storage technologies are used.

The levelized cost of rooftop solar generation is the lowest in India ($66/MWh) and China ($68/MWh), while the United States ($238/MWh) and the United Kingdom ($251/MWh) are some of the most expensive countries, according to a new international study.

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.

US data management company Iron Mountain has a growing portfolio of onsite and PPA renewables, and it’s one of the first major corporate firms to track its renewables by the hour as part of an innovative PPA that may serve as a forerunner for widespread 24/7 matching.

Panels being covered in volcanic ash can cause several problems – as has been seen recently with ongoing eruption in the Canary Islands. The weight of the ash may be too much for the structure to bear, sharp ash particles or small stones within the ash can scratch module glass, and acids or sulfur compounds contained in the ash can cause corrosion on the backsheet.

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.

A report from Australia’s Future Battery Industries Cooperative Research Centre which analysed the development of battery hubs in the U.S., Germany and Japan, has found that co-location and cooperation between industry and government were key to their success. For Australia to play the same game, it will have to leverage its wealth of resources, and clean up its act along the way.

A new study from researchers at the universities of Lancaster and Reading in the UK has managed to quantify the economic boost provided by the symbiotic relationship between solar farms and honeybee hives.

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.

South Korean company LG Chem has developed a new plastic material that it says could replace the metal frame of a PV module, making it much lighter. The company says it has already secured mass production capability for the material and begun selling products at full scale.

Shipments and revenue both rose in the first three quarters, for a company which this year announced the painful consequences of winding down its cell manufacturing operation were behind it.

The modular solar marketplace is growing, especially in Australia where remote mining and agricultural sites appreciate the benefits of compact, movable solar. One new entrant is Western Australia’s CDI Energy with its “Rapid Solar Module”, which CDI founder and CEO Darryl Bower told pv magazine is up to 30% cheaper than fixed axis alternatives.
