2020 was the year for mega-solar projects to strike record low prices – US$0.0135/kWh in Abu Dhabi for the unimaginably vast 2 GW Al Dhafra project. Not to be left behind, some Australian project developers are pursuing equally grand plans with cleantech guru Michael Liebreich saying that their likelihood for success will lie in what the proponents plan to do with the vast amount of clean, cheap energy.

Having supplied more than 450 MW of residential solar systems in 2020, Chinese inverter giant Sungrow is confident that 2021 will be the year it cracks the utility scale segment. It is also set to introduce a new battery for the distributed market segment, says Sungrow Australia country manager Joe Zhou.

South Australia rounded out 2020 with a record-setting day, in which solar and wind supplied 99.6% of demand on the state’s electricity network on Dec. 27. But as solar veteran and Amrock MD Pierre Verlinden explains, there is some serious infrastructure needed if the state is to realise its 100% renewable ambition.

A small number of utility-scale PV arrays of an entirely different nature are taking shape Down Under. Over the past six years, Aussie solar startup 5B has been developing and deploying its pre-assembled and relocatable Maverick mounting structures “on a shoestring budget.” But with a major solar developer having joined as a strategic investor, the company is now looking to make prefabricated arrays a mainstream option for utility-scale PV.

Guarantees and warranties may be thought to deliver peace of mind, but when underperformance on rooftop systems is detected, diagnosing and demonstrating failures is no simple task. pv magazine’s Virtual Insight on Quality event in November tackled this issue from all angles – and what it means for Australia’s burgeoning rooftop segment.

The regular cleaning of solar modules results is optimized power output and protects installations against costly failures. There are multiple approaches to module cleaning, both low-and-high tech. Pol Duthoit from SolarCleano sets out the need and the options.

With PV manufacturer warranties being extended and new novel designs coming on to the market at greater frequency, the quality assurance practices standing behind claims are becoming increasingly important. A new program from TÜV Rheinland is looking to provide the assurance that installers, distributors and project developers need – particularly in the hot and humid environments proven to push the boundaries of module durability.

While long hyped, uptake of residential battery storage is continuing to underwhelm, according to BayWa r.e. Solar Systems managing director Durmus Yildiz. In the wake of the Insight on Quality session of the All-Energy Australia virtual conference, Yildiz says he has reservations about battery safety and quality, and that education is needed to drive the application’s growth.

The winners of the Clean Energy Council’s 2020 solar design and installation awards announced today have been applauded as stunning examples of the innovative solutions being deployed in the commercial rooftop solar sector (C&I) as more businesses look to reap the benefits of solar.

Stable pricing, stable product performance, and rapid after-sales service: These are the pillars on which Chinese PV manufacturing giant Longi’s rapid growth in the Australian market are built – says Stephen Zhang, the MD of Longi Australia. And as the company moves towards another year of doubling its shipments to Australia, its local presence and team remains a vital part of its strategy.
