The global energy transition began at different times for different nation states. Iceland and Costa Rica had natural advantages but Germany took the lead in establishing the formula for every country to embark on an energy transition. What began a quarter of a century ago is now entering the next phase: a select group of nations undergoing an energy transformation.

There is no consensus on the future of PV technology but there is general agreement that existing silicon solar cells do not represent the pinnacle of solar energy generation. This has resulted in the exploration of alternative materials and device architectures, with tandem solar cells emerging as the front runner for the next generation of solar cells to be deployed at scale.

There was excellent news at the weekend on Australia’s accelerating progress in slashing consumers’ skyrocketing energy bills and transitioning the community to cheap, clean, reliable firmed renewables. Prime Minister Anthony Albanese’s announcement of a $2.3 billion program to subsidise the purchase of household batteries will deliver a 30% rebate on the price of battery systems from 1 July 2025, with small business and community facilities also eligible.

The Australian government’s move to introduce new standards for vehicle-to-grid charging enables the nation’s electric vehicle owners to tap into the technology to charge their car batteries when they want and discharge back into their house or the grid when it suits their schedule.

Every commercial solar system ever built, or ever to be built, will inevitably require maintenance. Yet, across Australia’s renewable energy sector, maintenance remains chronically overlooked – often treated as an afterthought rather than an essential part of solar asset management.

Power prices are set to go up again even though renewables now account for 40% of the electricity in Australia’s main grid – close to quadruple the clean power we had just 15 years ago. How can that be, given renewables are the cheapest form of newly built power generation?

Australia’s rapidly growing solar PV industry faces mounting cyber risks that no operator can afford to ignore. PV systems rely on intricate supply chains, incorporating hardware and software from multiple vendors. Each link in this chain – be it a component manufacturer, a software provider, or a maintenance contractor – can introduce potential entry points for cyberattacks.

DNV company Solcast reports that solar generation in parts of eastern Australia is set to face significant disruptions as Tropical Cyclone Alfred hits the Queensland coast. Other areas may benefit from enhanced solar irradiance due to stabilising atmospheric conditions on the cyclone’s periphery.

As any industry goes through an evolution, its workforce needs to do the same. Australia’s energy sector is going through major changes. Fueled by strong government and private sector investment along with rising community demand and expectations, the industry needs to ensure it has the skills our future energy network requires. And the only way it is going to do that is by attracting more women into the industry.

The solar energy industry continues to push the boundaries of efficiency and reliability. However, as innovative photovoltaic cell and module technologies emerge, they also bring a new set of challenges in durability and performance. A new report from IEA PVPS Task 13, titled “Degradation and Failure Modes in New Photovoltaic Cell and Module Technologies,” offers a comprehensive analysis of degradation and failure mechanisms in current photovoltaic technologies.
