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.
Latest coverage
Why India’s Rooftop Solar Won’t Buy Batteries
India’s rooftop solar hit 30.7 GW, but net metering means a home battery takes nine years to pay back. Ember finds a ₹28,000 crore subsidy could unlock 15–25 GWh the grid needs.
Australia Opens Its Solar Rebate to Commercial Roofs
Australia has lifted its upfront solar-rebate cap tenfold, from 100 kW to 1 MW, extending a ~20% discount to commercial roofs that hold an estimated 80 GW of untapped capacity.
China’s Molten-Salt Bet: Solar That Runs After Dark
China just grid-connected a 1 GW solar plant that runs after dark, storing eight hours of heat in molten salt instead of lithium – the firming trick the West wrote off.
The BrightVolt Take: Pakistan’s Solar Boom Is a Grid Failure
Pakistan installed an estimated 27-38 GW of rooftop solar in two years with no subsidy and no plan – the state counts just 6 GW. Its 2026 net-billing clampdown is the admission.
Alberta’s $14 Solar Panel Recycling Fee Starts Oct 1
From October 1, Alberta charges C$14 to recycle every new solar panel and bans them from landfill. The industry backs recycling but calls the fee a punitive tax set with math it won’t show.
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.
