SpaceX's Terafab mega-chip factory in Grimes County, Texas will be powered by newly built natural gas plants and large battery arrays, with no Tesla solar in the plan despite Tesla’s partnership; the site sits on a former coal plant and aims to churn out over a terawatt of compute annually for SpaceX and xAI, plus future chips for Tesla, marking a gas-first approach for AI data centers amid debates over solar power and reliability.
The Trump administration announced 15% tariffs on all imported polysilicon components and set minimum import prices (e.g., $21/kg polysilicon, 22¢/W cells, 38¢/W panels), effective December 4, 2026, aiming to bolster U.S. polysilicon production and onshore the solar supply chain. The move could raise imported-panel costs while encouraging domestic investment, with industry players like Qcells and Corning welcoming the policy and a broader AD/CVD framework expected to follow for additional countries.
The FCC announced blocking new imports of advanced, foreign-made robots and power inverters used in solar projects due to perceived cybersecurity and supply‑chain risks linked to China; waivers can be pursued through a Pentagon/DHS process, and the policy does not affect existing devices or federal procurement.
The US FCC has approved Reflect Orbital’s plan to launch a constellation of sun-reflecting satellites, beginning with the 60‑foot Eärendil-1 prototype, to illuminate dark areas and support solar power after sunset. The project envisions up to 50,000 mirrors by 2035, but astronomers warn the mirrors could disrupt observations and light pollution, while biologists voice concerns about ecological and circadian impacts. Critics question whether such a fleet is feasible or safe, even as the company touts a possible fossil-fuel替ing energy source, and public comments on the proposal were highly critical.
Kyushu University researchers designed a solid-state organic material by attaching alkyl chains to dihydroindenoindenedene (DHI) to create precise gaps between molecules, enabling efficient triplet energy transfer. This yields a solid-state fluorescence quantum yield over 60% and, with a donor partner, about 1.9% visible-to-UV upconversion under outdoor solar light, opening possibilities for solar-driven photocatalysis, indoor air purification, and low-intensity 3D printing. A patent has been filed, highlighting the approach as a major step in photon upconversion and molecular self-assembly research.
University of Rochester researchers built a solar-powered desalination device with a laser-etched black surface that absorbs most sunlight and draws a thin water film to distill fresh water, while moving the salt to untreated edges to avoid clogging and leaving no brine waste. The surface remains self-cleaning across ocean water, and a related version seeded with nanoparticles can remove lithium from Great Salt Lake samples.
Europe's heatwave boosted solar output, pushing some wholesale electricity prices below zero as solar met a large share of midday demand. The episode shows how surging renewables can depress prices even as grid and storage constraints limit benefits, with wind and hydro also pressured by heat. Analysts say expanding battery storage and upgrading the grid are essential to manage negative pricing and potential bill impacts.
Once a vocal advocate for a 100-by-100 mile solar solution to power the U.S., Elon Musk now runs xAI's Grok on 62 unpermitted methane gas turbines at two data centers, and has begun selling compute to Anthropic while positioning a space-based solar pitch to justify SpaceX’s planned $1.75–$2 trillion IPO. Grok’s popularity has fallen, the economics of orbital data centers remain dubious, and Musk’s pivot appears driven more by financial engineering for an IPO than by a practical solar energy revolution.
Researchers at UC Santa Barbara unveiled a liquid solar battery that captures sunlight and stores it indefinitely in chemical bonds using a DNA-inspired pyrimidone molecule (MOST technology), releasing heat on demand. With an energy density of about 1.65 MJ/kg—roughly double that of lithium‑ion batteries—the system could heat homes or power off‑grid applications without relying on the electrical grid.
U.S. prosecutors asked a Brooklyn judge to dismiss criminal fraud and conspiracy charges against Indian billionaire Gautam Adani in connection with a solar-power deal, citing prosecutorial discretion; the judge must approve, and Adani has never been arrested or faced trial. The move follows a related SEC settlement and years of scrutiny over Adani’s ties to the Modi government and past allegations of misconduct in the energy sector.
A Tom's Guide hands-on review finds the Anker Solix C300, a 288Wh portable power station, can run basic lights and gym gear in a garage far from the mains when recharged by solar. It delivers up to 300W continuous (600W surge) and accepts up to 100W solar input, with the PS100 panel recharging the unit in about four hours in sunny conditions. It won’t run high‑draw appliances like a dryer or heavy power tools, but it’s a cost-effective backup for spaces disconnected from the grid, especially when portability and modular solar charging are valued.
Despite oil disruptions from the US-Iran war, a surge in China’s solar exports—68 GW in March—drives a global solar boom, with 55 countries setting all-time records and Africa and Asia showing strong demand; the piece notes the irony of boosting renewables and China while Trump has opposed both, and it raises questions about China’s solar overcapacity and whether current demand can absorb it.
The IEA’s 2025 analysis shows solar PV posted the largest annual increase of any energy source, driving renewables-led growth and meeting a large share of the rising electricity demand, while rapid battery expansion supports a more electrified, storage-enabled grid and emissions grew only modestly compared with past years.
Researchers converted balsa wood into an all-in-one solar energy system by delignifying the wood, nano-engineering its channels with black phosphorene protected by a tannic acid–iron layer and silver nanoparticles, then filling the pores with stearic acid for heat storage. The material stores about 175 kJ/kg, converts roughly 91% of sunlight to usable heat, and can generate up to 0.65 V with a thermoelectric generator after illumination ends, while remaining durable over cycling and highly water-repellent. This wood-based approach could enable compact solar storage and heat management in electronics, pending scale-up.
Researchers in Japan and Germany report a lab method using tetracene and molybdenum to split high-energy blue photons, enabling singlet fission that yields about 130% energy conversion efficiency—surpassing the traditional Shockley–Queisser limit in controlled experiments. While promising, these results are early-stage and not yet practical for commercial panels, which remain around 25% efficient.
