California utility PG&E has tested levels of residential solar power up to 100% penetration, and how to mitigate the effects of voltage and thermal overload via smart inverters and traditional transformer and circuit upgrades — with smart inverters shown to allow for up to 100% penetration at cost-effective pricing.

A total of 238,000 advanced meters will be installed by Western Power on the South West Interconnected System over the next three years, unlocking the benefits of the technology that gives consumers more control over their energy use. In another rollout, Horizon Power has made paying for power easier for 11 Aboriginal communities across regional WA.

Thirteen of Victoria’s water corporations have partnered to buy clean energy from the Kiamal Solar Farm in north-west Victoria, at a much cheaper rate than would be possible individually.

Renewables are the lowest cost, sustainable solution for Australia’s energy policy crisis and potentially one of Australia’s largest export industries of the future.

Rooftop solar remained the biggest employer in the Australian renewable energy sector last financial year, but it was large-scale solar PV that stole the limelight as it emerged as the second largest contributor of direct full-time jobs.

The world had more than half a terawatt of PV generation capacity at the end of last year as emerging solar markets picked up the slack caused by Beijing’s subsidy about-turn to the tune of a 20% rise in installations outside China.

The state grid operator reported breaking 11 GW of instantaneous power from large scale solar on Saturday at 1.50pm. Just 20 minutes earlier, the CAISO grid was exporting a record 1.5 GW of electricity, and last Wednesday it hit 93% clean electricity for a moment.

Solar could meet approximately 68% of global energy demand with other renewables making up the rest, according to a new report. A 100% renewable energy system could also create 22 million solar jobs by 2050, the study claims. Keeping global warming below 1.5 degrees C, though, would require FITs for projects up to 40 MW in capacity, auctions for bigger systems, removing fossil fuel and nuclear subsidies and providing more education and R&D and less red tape.

German battery maker sonnen is following its takeover by Shell with plans to expand its market reach. It says it will use the opportunity to jointly push the energy transition. With an eye on sustainability, sonnen has launched an industry-wide initiative to push cobalt-free lithium-ion batteries for home storage systems.

The Queensland government has laid down regulations for solar farms that will allow only licensed electricians to install or remove PV panels. But the new rules will put hundreds of local jobs at risk and could bring some projects to a standstill, the Clean Energy Council (CEC) has warned.
