The weekend read: Time is now for HJT

There’s nothing new under the sun, and this is ever so in PV. So it should come as no surprise that the hottest new cell technology has actually been in mass production for decades. But is now the time for heterojunction to move into the mainstream? There are serious challenges to overcome if so, but momentum is undoubtedly building.

France’s EnerGaïa, Italy’s Key Energy to be held in fall, Australia’s All-Energy 2020 canceled

France’s EnerGaïa Forum will be held Dec. 9-10 in Montpellier, while Italy’s Key Energy event will be held in Rimini from Nov. 3-6. Australia’s top PV industry event will not take place in 2020.

Australian rooftop PV may face grid constraints

The ability to feed electricity from rooftop PV arrays into Australia’s distribution network may be severely limited in the future, as installations appear likely to exceed expectations. A Cornwall Insight forecast sees some 24.45 GW of rooftop solar to be added through 2030 – a rate that accelerates the need for a distribution-level market and may see connections curtailed in the future.

Canberra project REVS up Australia’s vehicle-to-grid readiness

The Australian Renewable Energy Agency is putting US$1.66 million into a vehicle-to-grid trial to demonstrate how electric vehicles can provide grid ancillary services. The REVS research and industry consortium hopes to show how EVs can generate revenue for fleet owners.

Chinese-made HJT hitting Australian rooftops

Risen Australia and distributor One Stop Warehouse signed an expanded 150 MW distribution deal last week, marking the Chinese manufacturer’s latest attempt to expand in the rooftop segment. With Risen’s new heterojunction module, the 415-435 W Sieger, now moving into mass production, One Stop Warehouse’s Leo Ye welcomed the “new, fresh” tech.

pv magazine video: The pressing need for sustainability in solar

The solar industry faces many challenges in its move to become truly sustainable and that goal is imperative, rather than being simply a luxury, if the sector is to achieve terawatt scale. pv magazine’s first Sustainability Roundtable took place on June 10 and included discussion as to why sustainability matters in PV and which business, regulatory and technological approaches can be applied to achieve truly “green” solar power. A video of the event can be streamed online.

The weekend read: Made in Israel

A reformed electricity market, officials who are supportive of PV’s new competitive position, and growing renewable energy ambitions are driving significant growth in Israel’s solar market this year. And with its homegrown hero in the background, solutions for the country to become a clean energy leader could already be in place.

Survey: Covid-19 to cause 50% decline in Australian rooftop solar

Australia’s previously booming rooftop PV market is likely to see a steep decline in the face of Covid-19-related shutdowns and uncertainty. An industry survey by pv magazine and Green Energy Markets prompted around half the respondents to report declines of 25-50% in customer enquiries, with a further 20% reporting new leads have dried up.

Australian rooftop solar surged to record highs before lockdown

Research by Green Energy Markets shows that the Australian rooftop PV market remained healthy throughout the first three months of 2020. According to STC data, more than 30,000 rooftop installations were registered in the month, for a total of close to 250 MW of capacity. And then came Covid-19.
