Crescent Dunes sold for $7M, but the real issue is the tank floor. Built to oil‑field specs, thin welded plates grind on the foundation daily. NREL models say those floors fail in under three years. The friction sparked repeated leaks, slashing output by 45% to keep it alive. It's a textbook case of scaling basics ignored. How can we enforce engineering checks on multi‑billion projects? #SolarEnergy #EnergyStorageSystems #EcoTech #GreenTechnology

Científicos de la Universidad de Warwick descubrieron una nueva forma de vanadato de bismuto denominada β-BiVO4 que se forma durante el calentamiento de precursores moleculares. Este material posee una estructura atómica diferente y una banda prohibida significativamente mayor, lo que le permite absorber la luz solar de manera más efectiva y generar combustible de hidrógeno limpio. Este hallazgo abre nuevas posibilidades para el desarrollo de combustibles solares, catalizadores y electrónica.

$975M plant sold for $7M – that’s the math on Crescent Dunes. After a second bankruptcy the Nevada solar tower changed hands, now run by a Houston contractor. It never hit 40% output; Four tank leaks derailed the schedule. Cost per kilowatt was nearly $9,000 vs China’s $2,200 standard. Molten‑salt storage in the US looks costly—does the tech still make sense here? #SolarEnergy #EnergyStorageSystems #Renewable #EcoTech

We ranked all 50 US states by residential solar payback in 2026 — the first ranking since the 30% federal tax credit expired. Hawaii pays back in 5.4 years; North Dakota takes 21.1. Surprise: cloudy Massachusetts (8.7) beats sunny Arizona (13.0) — electricity rates matter ~2x more than sunshine. https://www.joulepost.com/us-solar-payback-by-state-2026/?utm_source=mastodon&utm_medium=social #SolarEnergy #EnergyTransition #Solar

Dust, pollen and bird droppings can reduce the light reaching solar cells, but the effect varies with location, rainfall, panel angle and the type of dirt.
The IEA’s photovoltaic programme estimates soiling accounts for about 4–7% of global solar-energy losses.
In several North Carolina installations, an NREL study found pollen reduced output by up to 15%; cleaning with water and mechanical methods increased output by 5–11%, w…

#Arizona and #Hopi could see $181M in Biden-era #solar grants after courts reverse #TrumpEPA
by Ellis Preston October 1, 2026
WASHINGTON – "Arizona and the Hopi Tribe could regain $181 million for solar projects in low-income communities after two federal judges ruled the Trump administration unlawfully rescinded the Biden-era grants.
"The Environmental Protection Agency awarded nearly $7 billion in April 2024 under the #SolarForAll program, part of the Inflation Reduction Act.
"The Trump EPA terminated the program in August 2025. Only about $71 million had been disbursed at the time, according to an agency audit, though all of it had already been promised to the 60 or so grantees.
"Arizona received $42,000 of its $156.1 million grant, according to federal records on USASpending.gov. The #HopiTribe received $421,000 out of $25.1 million.
"In September, federal judges in the District of Columbia and Rhode Island issued rulings days apart striking down EPA’s termination. The rulings could clear the way for restoration of the grants, though neither judge directly ordered they be reinstated.
"The EPA said in a statement that it is reviewing the rulings and considering whether to appeal. "

Engadget’s Karissa Bell spent nearly 24 hours camping in Pebble Flow, an electric travel trailer with solar panels, wheel motors and iPad controls for temperature, lights, hitching and remote movement.
In the test, Bell connected it to a Rivian using the iPad; the process took about 45 seconds.
She found the interior comfortable for two, but noted that the water pump was noisy.
Pebble says the wheel motors can help…

Researchers at Jakkaru found that a flaw in Sungrow’s iSolarCloud could allow access to an account without its password, provided the person knew the user’s valid email address.
The platform manages solar installations, inverters and battery systems.
Researchers warned that an administrator account could allow changes to connected equipment; customer and administrator accounts were in the same management environment…
