Volcano proof PV

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.

Prioritizing electrification

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.

China’s emission-reduction action squeezes PV production

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.

More sun for everyone

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.

Nigeria’s solar workforce can help the world to net zero

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.

The evolution of residential PV in China

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.
