It was a record year for global shipments of single-axis solar photovoltaic (PV) trackers in 2018, as they increased by more than 40%, surpassing 20 GW globally for the first time, writes IHS Markit senior analyst Camron Barati. While the United States continued to be the largest individual market for single-axis trackers last year, shipments also increased in Mexico, Australia, Egypt, Spain, and other large utility-scale markets.

The U.K. government was the first major economy in the world to pass laws to end its contribution to global warming by 2050. But to achieve this ambition is going to take some major changes – not least of which to the U.K.’s power network.

The past year has marked a watershed moment in the global energy transition, driven primarily by the fact that public awareness of the challenges posed by climate change has skyrocketed.

Lead halide perovskite PVs (LHP-PV) have rapidly emerged over the last decade as a potentially viable thin film PV technology, because of their high efficiency and potential for low manufacturing costs. However, concerns remain over potential impacts to the environment and human health arising from the use of toxic lead in LHP-PVs.

Austrian researchers have proposed gravitational energy storage for locations with low demand. The scientists claim the system they are suggesting can be combined with other forms of storage as well as renewables, costs $50-100 per megawatt-hour of stored energy and $1-2 million per megawatt of installed capacity to develop.

According to the bidding terms published by the National Energy Commission, project proposals may be submitted by June 11 and the results will be announced on June 19. Successful bidders will secure a 15-year power supply deal and some 5.6 TWh of electricity is expected to be generated annually as a result of the new capacity.

Swedish company Exeger says the dye-sensitized ‘light-harvesting material’ it will produce at its facility will generate enough power to prevent the need to recharge portable electronic devices, lengthening battery lifespan perhaps indefinitely.

GCL and Canadian Solar provide further proof of the solar boom that is gathering pace around the world even as attention focuses on the Chinese market.

Complaints about sub-standard, cheap PV imports from China – and notably, India – have been heeded by Dhaka, which has issued a requirement for modules, inverters, charge controllers and batteries to attain IEC electrical standards.

The energy provider concluded its second renewables auction on November 13, and has contracted 121.6 MW of wind and solar. Selected projects will be granted a 15-year PPA and will have to begin commercial operations in 2023.

The clean energy arm of Israeli conglomerate Shikun & Binui will own the 120 MW plant near the village of Zeélim.

The Turkish government is planning to assign 100 solar projects with a capacity of 10 MW each across 39 different provinces via a new procurement exercise. The tender will be held on April 20, 2020.

The energy transition is becoming ever more apparent among power companies, as was evident at the European Utility Week event last week in Paris, which showcased the hopes and fears of energy companies. Rebranding next year to ‘Enlit’, the organizers aim to reach the whole energy industry.

The South Korean capital has unveiled a plan to deploy rooftop PV on a million homes and all public buildings. The new initiative is designed to bring the city’s cumulative installed solar capacity to around 1 GW by the end of 2022.

A research group at the Helmholtz Zentrum Berlin has conducted an in depth analysis looking at the crystalline structure of methylammonium lead iodide, one of the most promising perovskite materials for solar cell production. The group made a series of discoveries which they hope will help to unlock some of the remaining issues in creating cells that are both stable and highly efficient.

Scientists at Germany’s Karlsruhe Institute of Technology have received €4.5 million from the Carl Zeiss Foundation to begin a project developing an entirely new solar cell concept they say will combine the printability of organic PV, long-term stability of crystalline solar cells and ferroelectricity of lead-halide perovskites.

An international research group claims to have developed a new bulk perovskite semiconductor material that can capture the excess energy of hot electrons. The material is said to rapidly absorb as heat energy which would otherwise be wasted. With the harvesting of hot electrons, the maximum theoretical efficiency for hybrid-perovskite solar cells could increase from 33% to 66%.

This year’s record-breaking event held in Lisbon, Portugal, included an energy track devoted to renewable sources and technology to address climate change.

Toxicologists are struggling to follow the pace at which perovskite solar cells race from laboratory test benches to factory production lines. While researchers continue to assess the health and safety risks stemming from the lead used at the core of these new materials, the startups commercializing them argue that established encapsulation techniques and sound recycling schemes are enough to safety-proof their potentially disruptive technology and offset broader environmental threats.

A new series of tweaks by Solar Energy Corp. of India appear to have paid off, as the organization’s ambitious, manufacturing-linked 7 GW solar tender has been oversubscribed by 1 GW.

A series of new amendments by the Solar Energy Corporation of India appear to have paid off, as the organization’s ambitious manufacturing-linked solar tender has reportedly ended up oversubscribed by 1 GW – of the capacity offered as an incentive at least.

The new cell is based on a p-type transparent conductor made of carbon nanotube fibers. The device is said to offer 16% more efficiency than rival amorphous cells.

A researcher has proposed a new approach to apply maximum power point tracking techniques to optimize electricity production in wind-solar power projects. The permanent magnetic synchronous generator hybrid model used in the study is based on a multi-input rectifier stage which is said to be able to eradicate current harmonics and eliminate the need for extra input filters.

Chinese polysilicon giant Daqo New Energy posted $83.9 million in revenue in the third quarter for gross profit of $18.1 million. The company has an additional 35,000-ton production facility set to come online this year.

A cooperation agreement was signed by the French corporations to launch the HyGreen Provence project, which is expected to produce annually 1300 GWh of solar electricity and 10,440 tons of green hydrogen by 2027.

Australian startup Power Ledger wants to scale up its offerings for much larger communities, as it has already verified its technologies in projects around the world. The Australian Energy Market Commission last week proposed a similar agenda.

The Salt River Project has announced a 250 MW, 1,000 MWh battery project in Little Rainbow Valley, Arizona. The installation will be the largest in the state and among the largest in the United States.

The investment manager is now Europe’s largest renewable energy fund. The €1.3 billion group already has a 1.8 GW generation portfolio.

The state’s 2019 IRP sees just over 11 GW solar power, and at least 11 GW – with up to 19 GW – of energy storage necessary to meet resource adequacy as part of the state’s legally required 60% renewable portfolio standard by 2030 as prices have fallen 50% since 2017.
