Battery innovations started to come thick and fast this quarter as the hunt for alternatives to lithium-ion intensified and the latest slew of solar tenders indicated the relentless pressure on solar power generation costs was showing no sign of abating.

Storage has long been expected to be the handmaiden of a renewable energy world and its long awaited advances started to finally emerge in the third quarter as researchers posited R&D achievements ranging from potentially potent tungsten disulfide nanotubes to the business case for 10-year solar panels.

At its recent “Analyst Day” presentation, the company also showed off a 640 W two-module commercial inverter, as well as an “Ensemble in a Box” solar+storage package for two PV modules.

Tesla finishes 2019 on a high note amid a flurry of year-end EV funding, news and optimism on longer-range electrics.

With its trade wars, exclusions from tariffs, reversals of exclusions, and stays of reversals of exclusions – in addition to the repeal of the Clean Air Act and potential changes to the Public Utility Regulatory Policies Act – the U.S. solar market is anything but boring, writes SPV Market Research’s Paula Mints.

Intersolar Europe is always a key date in the solar calendar but this year’s show had it all, including three panel-smuggling arrests. Elsewhere, wafers were getting bigger, efficiency records were tumbling and new technologies were emerging. There was also more news on the solar car ports fad and Hanwha’s ongoing legal tussle.

Finnish lender Nordea has called in a NOK150 million indemnity loan thought to have been taken out by REC Silicon ASA as a result of the bankruptcy of its Norwegian wafer manufacturing arm seven years ago.

The first part of pv magazine’s review of 2019 considers Q1, when solar early adopter Italy offered an optimistic start to the year by fleshing out its plans for PV but uncertainty still clouded the world’s biggest solar market. The potential for household solar installations to rocket the world over – helped by ever cheaper panels – prompted strategic decisions in the inverter market and analyst expectations were confounded as the cobalt and lithium price plummeted, bringing the EV revolution a big step nearer.

U.S. scientists are trying to understand how non-fullerene small-molecule acceptors (NAFs) increase the efficiency of organic PV devices. They claim that methoxy groups embedded in the acceptors could facilitate an efficiency increase of approximately 6%.

CNBC has uncovered a recently granted building permit that allows Tesla to put up “two canopy covers” over its new “solar test houses.” Earlier this year, Tesla CEO Elon Musk announced that 2019 was “the year of the solar roof.”
