Forecasting model to manage renewables-powered grids
Scientists in South Korea have developed a forecasting model to better manage electric grids with high penetration of intermittent renewables. The model was tested using historic data from Pennsylvania-New Jersey-Maryland (PJM) grid in the United States, and shown to accurately forecast the availability of renewable energy resources up to one day in advance.
Second-life EV batteries as grid-scale storage
Smartville has secured $5.9 million from the US Department of Energy to scale its second-life battery program.
Solar tower of power shows benefits of vertical installations
Three Sixty Solar, a commercial and utility-scale solar developer, published a report this week that provides background on its vertically mounted solar system’s initial 16 months in operation.
Solar, storage provides energy solution for remote Australian town
The remote town of William Creek in the Australian outback is now entirely powered by solar backed by a battery energy storage system, after the switch was flicked on a 200 kW PV array that eliminates the need for diesel generation.
Viessmann unveils ground-source heat pump for space, water heating
Viessmann has developed a heat pump for residential applications that can produce between 5.8 kW to 10.4 kW of heat. It has the capacity to heat 220 liters of domestic water, with a coefficient of performance (COP) of up to 4.8 for space heating and 3.14 for water heating.
Guide to understanding solar production losses
Aurora Solar offers guidelines to make the most of a solar installation by avoiding losses.
Novel design for intermediate band solar cells
A UK-Australian research group has built an intermediate band solar cell with a quantum ratchet semiconductor nanostructure that reportedly increases the ratchet band state lifetime of the device. Their new design builds on a cell structure known as the Vaquero–Stainer Device (VSD).
New model estimates PV potential for water pumping in Africa
An international team has developed a numerical model that calculates how much groundwater can be pumped by PV systems of different sizes across the entire African continent. The results show that larger PV systems do not always pump the highest volume of water.
Fraunhofer ISE founder, solar pioneer Adolf Goetzberger dies
Adolf Goetzberger, the founder of the Fraunhofer Institute for Solar Energy Systems ISE and an early proponent of photovoltaics, passed away on Feb. 24 at the age of 94.
FuturaSun unveils n-type heterojunction solar modules
Italy’s FuturaSun has developed new bifacial double-glass PV modules based on n-type heterojunction (HJT) half-cut multi-busbar solar cells. The Velvet Pro line features M6 cells with power ratings ranging from 380 W to 480 W for rooftop applications. The Velvet Premium line features M12 cells, with power ratings from 615 W to 700 W for large-scale applications.
