- 1Renewables hit record 80% of demand on Australia's power grid●"Solar and wind generation meet record 80% of power demand on Australia’s national grid" # Australia # Energy # Renewabl
Solar and wind generation met a record 80% of electricity demand on Australia's national grid, a new high for the country's renewable energy transition. The milestone highlights how quickly rooftop solar and large-scale wind farms are displacing coal-fired power in Australia. Commentators are citing it as evidence that renewables can carry a large share of a major national grid, though questions remain about storage and reliability as coal plants retire.
- 2German Greens Reject EEG Reform, Defend Rooftop Solar Support▼Germany: Greens Reject EEG Reform, Defend Rooftop Solar Support
Germany's Green party is rejecting proposed reform of the Renewable Energy Sources Act (EEG), the country's core framework for funding renewable power. The party is standing firm on maintaining support for rooftop solar installations, which rely on feed-in payments under the EEG. The refusal signals growing political friction in Germany over how the country finances and structures its energy transition.
- 3Land Scarcity Pushes Solar Power Into Unlikely Spaces▼Space Squeeze Forces Solar Power Into Tight Corners
Reports highlight how shrinking availability of open land is pushing the solar industry to install panels in tighter, less conventional spaces. As large-scale solar farms compete with agriculture and development for ground, developers are turning to rooftops, car parks, and other constrained sites. Commentators in the energy press say land constraints are becoming a defining challenge for solar expansion worldwide.
- 4New South Wales trials battery models to extend solar benefits▼Australia’s NSW trials property-level and community battery models to extend solar benefits
Australia's New South Wales has launched trials of property-level and community battery models aimed at extending the benefits of rooftop solar to more households. The schemes will test how stored solar energy can be shared, easing grid pressure and lowering costs. The state is a leader in household solar uptake, making storage a key next step in its energy transition.
- 5Tongwei unveils 24.5%-efficiency rooftop solar module▼Tongwei launches TNC 2.0 FULLX G12R-48 rooftop solar module with 24.5% efficiency
Chinese solar manufacturer Tongwei has launched the TNC 2.0 FULLX G12R-48, a rooftop solar module built on its tunnel oxide passivated contact (TNC) cell technology. The company says the panel reaches 24.5% efficiency, a figure that would place it among the more efficient mainstream rooftop products on the market. The announcement adds to intensifying competition among Chinese module makers racing to commercialise higher-efficiency cell formats.
