Solar panels and inverters, home and grid batteries, off-grid power and energy self-sufficiency, and the industry around them.
Tesla says Model 3 and Model Y vehicles ordered after Oct. 1, 2026 can use Powershare to provide backup power for Powerwall users. The feature can supply two or more days of backup, but the cars cannot yet send power to the grid.
Cybersecurity experts advising the European Commission recommend restricting PV components and software from high-risk suppliers outside the EU across all market segments, including plug-in systems. They also call for third-party inverter certification under the Cyber Resilience Act.
South Africa is preparing to procure 4.6 GW of battery storage alongside gas-fired power plants to reduce curtailment and strengthen electricity reliability.
Maryland awards 15-year capacity credits to 440 MW of four-hour batteries in the first round of its 1,600 MW storage program. Two of five applicants withdraw, leaving the awards 360 MW below the round’s target.
Toyo marked the expansion of its solar module manufacturing facility in Humble, Texas, to 2 GW. One report says the site is planned to produce heterojunction cells in 2028; the other does not mention that plan.
A Wood Mackenzie report finds that four-hour battery storage is cheaper than open-cycle gas in 43 modeled markets. Tariffs threaten near-term gains for battery storage in the United States.
Brilliant Matters and HeiQ report semi-transparent organic solar cells with efficiencies up to 12.04% and fully printed modules reaching 10.2%, using the BM10 OPV platform and silver nanowire electrodes. They are targeting commercial availability in 2028.
South Korea's Ministry of Climate, Energy and Environment unveils the Korean Green Transformation industrial strategy, with a stated value of KRW1,000 trillion (US$747 billion). Solar, batteries and electric vehicles are among its designated key sectors.
Wood Mackenzie’s global levelized cost of electricity report finds that four-hour battery storage costs less to install than open-cycle gas turbines in all 43 markets it models. The report attributes the difference to advancing technologies and market dynamics.
Three phases of Doral Renewables’ Mammoth Solar Project in Pulaski County, Indiana, are set to begin commercial operation with combined capacity of 900 MWAC. The full Mammoth Solar complex is planned to reach 1.3 GW.
Global battery energy storage system failures per deployed gigawatt-hour fall 99% between 2018 and 2025, while installed capacity grows rapidly. The metric compares annual failures with deployed capacity rather than giving a raw failure count.
Finnish startup Truman Data launches Energy Coop, a virtual power plant platform that aggregates flexibility from buildings and batteries for electricity trading. The company says its revenue-share model avoids the long-term contracts common in battery-as-a-service deals.
Tata Power and Norway-based Ocean Sun are partnering on a pilot of Ocean Sun’s membrane-based floating solar technology in India. One report specifies a 300 kWp pilot; the other does not give its capacity.
Infrastructure investor Actis acquires two large-scale battery storage projects in Poland from DTEK’s DRI, with a combined capacity of 1.14GWh. R.Power and Solax also announce project updates in the country.
Italian startup Syntropia develops a 535W photovoltaic-thermal module that produces electricity and recovers heat, with 1.4kW thermal output. Recent tests report combined energy conversion efficiency of 66.8%, and the company is developing an integrated system with geothermal probes, heat pumps and energy management software.
In an interview, S&P Global Energy’s Edurne Zoco discussed persistent global PV supply-chain overcapacity, consolidation, regional price differences and the effects of China’s new efficiency standards. The coverage also addresses trade policies and risks and opportunities in inverter and battery storage markets.
Indosol’s Manoj Pothireddy says overseas wafer manufacturers still have opportunities to export wafers to the US amid a global supply chain imbalance.
Renewable energy data platform AMMP releases Ray, an AI coworker for asset management teams, designed to identify problems, explain them and draft reports, claims and decisions. It works within tools teams already use as renewable portfolios expand.
Chile approves the environmental assessment for Sidon Solar, a project combining 158.17 MWdc of solar capacity with 1,296 MWh of battery storage. The approval clears an important environmental step for the large solar-and-storage development.
Return has put its 100MW/200MWh Antares battery energy storage system into commercial operation in the Netherlands. The project is the largest battery storage system to reach commercial operation in the country, according to the supplied account.
