Today, state lawmakers returned to Columbia for the 2019 Session and will debate new legislation from Republican State Senator Tom Davis aimed at providing families, businesses, schools, and other energy consumers energy options by reducing costs, increasing competition, and maintaining the South Carolina’s popular net metering program. It will also expand solar options to renters and low-income residents through community solar. The ‘Clean Energy Access Act’ (Senate Bill...

Duke Energy today announced the completion and operation of its new 74.9-megawatt (MW) Hamilton Solar Power Plant in Jasper, Fla. The plant's carbon-free power is enough to energize more than 20,000 homes at peak production. Across Duke Energy's Florida service territory, the company's 1.8 million customers — and the environment — are now benefiting from approximately 300,000 solar panels that generate clean, renewable energy.  The Hamilton plant is part of the...

Silicon solar cells dominate the photovoltaic market today but the technology approaches the theoretical maximum efficiency that can be achieved with silicon as the only absorber material. Tandem solar cells, on the other hand, combine several absorber materials, enabling a better energetic use of the solar irradiance spectrum. Due to their higher efficiency potential, tandem solar cells have a promising future. After intensive research, scientists at Fraunhofer ISE in cooperation with...

For the first time, researchers at Lund University in Sweden have used advanced molecule design to create an iron molecule that can function as a photocatalyst to produce fuels as well as in solar cells to produce electricity.  The Earth-abundant — and therefore much cheaper — iron could replace the rare and very expensive metal complexes used thus far, such as the noble metals ruthenium, osmium and iridium. Long live the excited iron complex We are talking nanoseconds:...

Knowing which Americans have installed solar panels on their roofs and why they did so would be enormously useful for managing the changing U.S. electricity system and to understanding the barriers to greater use of renewable resources. But until now, all that has been available are essentially estimates. To get accurate numbers, Stanford University scientists analyzed more than a billion high-resolution satellite images with a machine learning algorithm and identified nearly every solar power...

Researchers at the Helmholtz-Zentrum Berlin (HZB) in Germany have achieved a record 25.5% conversion efficiency in a perovskite-silicon tandem solar cell after adding a microstructured foil over the perovskite layer to optimize the light management. Tandem solar cells could be one possible way to overcome the theoretical limit of the efficiency of silicon solar cells, which are still dominating the market. But while tandem devices made from combinations of silicone and GaInP or GaAs, for...

Larson Electronics announced the release of an explosion proof 5-stage solar LED light tower that deploys 400 watts of intense LED illumination to heights up to 30 feet. This light tower features four LED fixtures mounted on top of the 30-foot telescoping light mast and includes four C1D2 solar panels with a 1,000aH capacity battery bank. The

In cooperation with Global Himalayan Expedition (GHE), which leverages tourism to provide clean energy and digital education access to remote communities, REC Group contributed its solar panels that now generate energy in remote villages and schools in the Ladakh and Zanskar regions of India. Many of the communities in these sparsely populated regions have no access to grid-based power, and therefore rely on either very old solar lanterns or kerosene lamps for lighting. Thanks to the REC solar...
