- 1German 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.
- 2Australia's main grid runs on 80% renewables for consecutive days▼Australia's main grid hits 80% renewables on consecutive days, rooftop solar tops half of demand
Australia's main electricity grid has recorded 80% renewable energy across consecutive days, with rooftop solar at times supplying more than half of demand. The milestone highlights how quickly household solar and other renewables are displacing coal and gas generation in the national market, drawing attention as one of the fastest energy transitions among advanced economies.
- 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.
- 5CertainTeed launches Landmark PWR solar roofing system▼CertainTeed release new solar roofing system Landmark PWR
Building materials manufacturer CertainTeed has released Landmark PWR, a new solar roofing system. The product combines solar power generation with traditional asphalt shingle roofing, allowing homeowners to generate electricity without separate mounted panels. The announcement is drawing attention in the solar and construction industries as rooftop solar continues to expand in residential markets.
- 6Tongwei 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.
- 7City Solar Grant Covers Full Installation Costs for Income-Qualified Homeowners▼PRESS RELEASE: City Solar Grant Program Covers Full Installation Cost for Income-Qualified Homeowners
A city solar grant program announced that income-qualified homeowners can now have rooftop solar installations covered in full, removing the upfront cost barrier to clean energy. The program aims to expand access to renewable energy for lower-income residents and reduce household utility bills. Further details on eligibility criteria and application procedures have not been provided in the announcement.
- 8Community Solar Project Under Construction in Northeast Portland▼Community Solar Project Now Under Construction In Northeast Portland
Construction has begun on a community solar project in Northeast Portland, Oregon. Community solar projects allow residents, including renters and those who cannot install rooftop panels, to subscribe to a shared solar installation and receive credits on their electricity bills. The project adds to Portland's growing portfolio of renewable energy initiatives as Oregon pushes to expand clean power access across the state.
- 9Free tool estimates rooftop solar capacity from a photo▼Free software calculates how many solar modules fit on a rooftop from a photo
A free software tool can now calculate how many solar modules fit on a rooftop using just a photograph. The tool is aimed at helping homeowners and installers quickly assess a roof's solar potential without a site visit, by estimating available space and panel count from images.
