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 long-distance transportation of hydrogen is a major challenge. However, the total decarbonization of green hydrogen transportation may possible by envisioning hydrogen-filled rigid or frameless airships (blimps) which work on the buoyancy of hydrogen to lift and transport.

The temporary measures enacted by the Spanish government in mid-September to reduce the price of electricity affect many owners of wind and solar power plants on the Spanish mainland to varying degrees.

As the solar market enters the busy season in September and October, module utilization rates are reaching 70% to 85%. However, structural shortages remain in the supply chain, with polysilicon supply running short in the face of high demand, writes PV InfoLink analyst Amy Fang. Prices, which were expected to stabilize, rose again in the second half. High module prices will cast a shadow on demand in the fourth quarter, prompting module manufacturers to postpone delivery for some orders from the second half into next year.

In the last of the series, solar pioneer Philip Wolfe looks at areas where solar generating stations are clustered together, without the coordination of organised solar parks.

A report by the IEA laying out two routes for China to reach net zero attempts to persuade policymakers to gun for that goal by 2050, rather than ten years later, and dangles the prospect of continued global dominance as the main reward on offer.

A combination of booming demand for coal-fired power and a shortage of the black stuff – exacerbated by a political row with Australia – have forced up prices to the extent fossil fuel generators are making a loss on every unit of electricity they produce. pv magazine‘s Vincent Shaw considers the potential solutions.

South Africa’s Renewable Energy Independent Power Producer Procurement Programme (REIPPPP) never ceases to amaze in terms of how different, exciting, competitive, and tough project bid submissions can be from one round to the next.
