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.

Prices for power purchase agreements have been rising steadily since the end of last year. According to solar developers, interconnection delays, permitting challenges, and supply chain constraints are likely to keep them high.

The shortlisted developers are Jinko Power, Total, ACWA Power, Alfanar, and a consortium formed by Masdar and EDF.

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.

One PV installer in Wales said he has experienced a 1,000% surge in demand for solar panels as rocketing gas prices have forced small energy suppliers in the U.K. to the wall and created uncertainty in households.

Big rooftop PV systems on factories, warehouses and public buildings need not be limited by ownership issues nor local grid capacity, claims Australian innovator EleXsys Energy. The company is maxing out an Ikea in Adelaide, Australia, with solar and storage. And it claims its smart technology can allow the same to be done elsewhere.

Spanish company Axial Structural is introducing a new type of tracker for agrivoltaic installations. The product can be adapted to various ground conditions and gradients, with programmable to optimize light and shade for different crops in different climates.

The two countries have signed a memorandum of understanding (MoU) to develop a new subsea electricity line connecting their power systems. The power link, if built, could provide a route for African solar energy to reach European markets.

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.

Mobile test equipment is a must for fault detection and performance monitoring of large-scale PV installations. The Australian PV Institute has contributed to an international review of available aerial and portable ground-based technologies, and how to deploy them for reliable, relatable results.

Among other announcements, the U.S. Department of Energy has awarded financing to a consortium of public, private, and academic experts to demonstrate a large-scale liquid hydrogen LH2 tank, a new hydrogen strategy has been unveiled by Australia’s New South Wales (NSW) state government, and Repsol and EDP have teamed up to assess new investment opportunities in renewable hydrogen projects across the Iberian Peninsula.

Scientists in the United States have developed a method to compare the performance and number of defects in different perovskite cell materials. Based on simulations and work with prototype materials, the group finds that all-inorganic materials have higher potential efficiency than their more widely researched organic-inorganic counterparts.

This week, Shuangliang Eco-Energy has signed a multi-year sales contract for delivery of its PV wafers to solar cell manufacturer Jiangsu Runergy, and Wuxi-based perovskite start-up UtmoLight Technology has won a Pre-A round investment of RMB 220 million from several private equity funds.

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.
