Precision beneath the panels: The hidden engineering inside a solar project
A deep-dive into the precision engineering and metallurgical resilience that sustain the world’s utility-scale solar infrastructure.
Growing pains: Grid congestion as a renewables bottleneck
The electricity grid is a real bottleneck for energy in the United States, and it’s not only utilities and grid operators who are struggling. Grid congestion also puts pressure on renewable energy project owners and is as much a business problem as it is a technical one, writes Alon Mashkovich, CEO of energy management business software supplier enSights.
The richest silver mine isn’t underground: It’s in solar panels
As primary silver grades decline and solar demand surges, the industry must transition from viewing retired panels as waste to treating them as high-grade mineral reserves essential for the energy transition.
The future of solar is unwritten
Whatever decision the U.S. Department of Commerce makes on polysilicon imports, some market segments are in for a bumpy ride in 2026 as the expiration of tax credits and other policy levers change the trading environment faced by residential installers and others. Jesse Pichel and Lev Seleznov of Roth Capital assess what lies ahead for U.S. solar.
Beyond rectangles: How geometry-constrained optimization can unlock more rooftop solar
Rethinking solar panel geometry beyond the traditional rectangle can unlock significant energy potential by optimizing coverage on complex, irregular rooflines.
Rethinking solar and storage ROI: Beyond old efficiency assumptions
Legacy solar models focused on daytime production, but the shift to battery-driven self-consumption is creating a performance gap that puts long-term ROI at risk.
Polysilicon transactions remain subdued amid buyer hesitancy
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
NERC Category 2 wake-up call: Register and comply or risk million-dollar daily fines

Winter Storm Fern disrupts North American solar in late January
In a new weekly update for pv magazine, Solcast, a DNV company, reports that January 2026 began with relatively mild, solar-favorable conditions across much of the eastern U.S., but ended with Winter Storm Fern, as a polar vortex disruption triggered widespread cold, clouds, and sharply reduced solar generation. A rare S4-level solar radiation storm was also recorded in mid-January, though it had no direct impact on photovoltaic performance or solar data quality.
Four reasons why grid services are the unsung hero of the U.S. clean energy future
Grid services and VPPs turn everyday home devices into a dynamic, cost-effective solution for a modernizing electric grid.
