Amazon hits 100% renewable energy goal seven years ahead of schedule
The retail giant matched 100% of the electricity used in its operations with investments in renewable energy in 2023.
Solar panel cleaning with electromagnetic waves
Three companies, including Massachusetts startup Sol Clarity, are experimenting with electrodynamic screen systems to clean solar panels using minimal electricity and no water.
Residential PV power forecasting method based uniquely on direct radiation
Researchers in Spain have created a novel PV forecasting method that uses only direct radiation as a parameter. They found it to be “comparable, if not superior” to four established forecasting techniques. The method could help homeowners with PV systems decide when to use electricity-intensive appliances and cleaning systems.
Organic solar cell gains counterintuitive efficiency boost from entropy
A research team at the University of Kansas found that organic semiconductors known as non-fullerene acceptors demonstrate a high solar cell efficiency due to a reversed heat flow.
REIT completes commercial-scale solar tax credit transfer
Solar developer Black Bear Energy said the real estate investment trust’s (REIT) transaction on the 556 kW portfolio is proof of concept that demand exists for credits of this size and risk profile.
With great (solar) power comes great responsibility
Consumer protection and transparency are the keys to reigniting industry growth. Josh Levine, vice president of marketing, EnergySage shares his perspective.
Researchers build 16%-efficient mini perovskite solar module resistant to UV light-induced degradation
A U.S. research team has built a 15 cm2 perovskite solar module with improved stability and efficiency thanks to a polymer hole transport layer that reportedly improves the panel stability and efficiency.
World’s first anode-free sodium solid-state battery
Researchers at the Laboratory for Energy Storage and Conversion have created a new sodium battery architecture with stable cycling for several hundred cycles, which could serve as a future direction to enable low-cost, high-energy-density and fast-charging batteries.
The Hydrogen Stream: Hydrogen power plants feasible but inefficient, says CATF
The Clean Air Task Force (CATF) says in a new report that dedicated clean hydrogen production and use is often a costly, inefficient decarbonization strategy for the power sector, while American Airlines says it has signed a deal with ZeroAvia for 100 hydrogen-electric engines.
Solar tariffs could “unintentionally cede U.S. leadership in the solar industry”
A report from Clean Energy Associates (CEA) and the American Council on Renewable Energy shows how antidumping and countervailing duty (AD/CVD) tariffs create cost issues not just for imported solar panels, but for U.S.-made solar panels as well.
