Dow releases new silicone gel for high voltage PV
The company said that its Dowsil EG-4175 Silicone Gel resists temperatures of up to 180 C in next-generation IGBT modules used in inverters.
Uncovering attitudes towards agrivoltaics via community engagement
An American research group has conducted a pilot workshop for agrivoltaics stakeholders in Arizona, including farmers, developers, government officials and indigenous leaders. A reflection paper offers some key takeaways for future public participation.
New deep learning tech for PV inverter fault diagnosis
A team of scientists at Georgia Southern University has combined both spatial and temporal attention mechanisms to develop a new approach for PV inverter fault detection. Training the new method on a dataset created in MATLAB/Simulink, the group has compared it to a series of other data-driven and statistical-based methods and has found accuracy reached 97.35%.
Bradford White releases residential hybrid electric heat pump water heaters
The U.S.-based company says its new AeroTherm G2 uses both electric and heat-pump-based heating. It ranges from 189 L to 303 L in capacity.
Enertech unveils geothermal heat pump for residential use
The heating specialist said its new variable-speed water–to–water system has a coefficient of performance of 3.2 at full load and 3.8 at part load.
CSP-driven multigeneration system combines hydrogen generation with compressed air, pumped hydro storage
Researchers have designed a novel multigeneration energy system that provides five outputs, namely electricity, hydrogen, cooling, heating, and hot water. The system is mainly powered by a solar heliostat system and incorporates compressed air and pumped hydro storage technologies for storing surplus power.
How to assess bifacial PV system performance on sloped terrains
Scientists have developed a precursor formulation for different PV simulation tools that can help calculate the expected performance of solar farms deployed on hilly slopes. Validation tests against an experimental setup showed an error of less than 3%.
Quantum-based energy management method for PV-powered buildings
Scientists from Cornell University combined quantum computing with model predictive control to manage the energy of two PV-equipped university buildings. Compared to deterministic approaches, the quantum strategy achieved a 6.8% improvement in energy efficiency and an annual reduction of 41.2% in carbon emissions.
Ecoflow launches 286 Wh portable power generator
The US-based company said its new River 3 Plus portable power station recharges from 0% to 100% in just one hour via AC outlet A version that includes wireless charging via an integrated 5,000 mAh power bank will be available later this year.
Experimental EV battery charges in 10 minutes in sub-zero temperatures
U.S. scientists have developed a lithium-ion battery for electric vehicles that enables high range and fast charging in cold weather. The battery uses a single-ion conducting glassy solid electrolyte coating and does not require changes to chemistries or production processes.
