Solar Power
Solar’s problem in 2026 is not cost, it is value. When a country’s panels all generate at the same moment, the price that power earns collapses — the capture rate — and in parts of Europe midday prices now sit below zero for hundreds of hours a year. That changes what a solar project is worth without changing what it costs to build.
Our coverage runs from utility-scale procurement and capture rates through to rooftop economics, agrivoltaics, and the storage that increasingly decides whether a solar business case closes at all.

US Solar Modules Hit 100 GW. The Cells Are Imported
The US has built 100 GW of solar modules, most of it since the IRA. But module assembly is the easy step, and domestic cell capacity sits near 3 GW against 65 GW of module lines.
Perovskite’s 27% Record and the Number That Ships
A Nanjing team pushed perovskite-organic tandem cells to a certified 26.88% — a real record, and the wrong number to watch. The efficiency that ships, and how long it lasts, lag far behind.
Land Equivalent Ratio: The Number That Sells Agrivoltaics
The land equivalent ratio is the headline metric for solar farms grown over crops. It almost always tops 1 by design – and it hides the harvest it cost to get there.
Red States Are Building 71% of New US Solar
States that voted for Trump built 71% of new US solar in the first half of 2026 — led by Texas at 3.44 GW — even as Washington dismantles the credits that helped start the boom.
The BrightVolt Take: ‘Anytime Solar’ Is a Ceiling, Not a Fact
The Ember report that coined ‘anytime solar’ found 2026’s batteries could shift 34% of new solar into non-sunny hours. That figure is a theoretical ceiling the fleet is running a third idle beneath.
US Wind and Solar Overtook Nuclear in the First Half of 2026
US wind and solar generated about 420 TWh in the first half of 2026 — a fifth of the country’s electricity and more than nuclear — even as Washington moved to repeal the credits that built it.
The BrightVolt Take: Solar’s Record Half Is Already the Past
US wind and solar passed both coal and nuclear in the first half of 2026 — 420 TWh, 20% of the grid. But that record was locked in before July’s subsidy cliff. Watch construction starts, not output.
Solar Capture Rate Explained: Why More Solar Earns Less
A solar farm’s capture rate is the share of the average wholesale price it actually earns. Europe’s hit a record-low 38% this spring; France managed 9.5% in April. Here’s why it falls, and what raises it.
Agrivoltaics: What 320 Experiments Actually Found
Of 264 crop trials under solar panels, 59.8% yielded less than open field and 12.9% more. The case for agrivoltaics survives that, but not in the form it is usually sold.
