SMA America releases 99.2% efficient grid-scale battery storage inverter
The inverters use a silicon carbide metal-oxide-semiconductor field-effect transistor for high power conversion capability.
EU launches partnerships to strengthen PV, advanced materials, textiles
The European Commission has established three Horizon Europe partnerships to improve technological prowess, industrial strength, and eco-friendly innovation, channeling nearly €1.1 billion ($1.19 billion) by 2030 into photovoltaics, advanced materials, and textiles.
Austa launches low-voltage hybrid inverter series
The single-phase inverter series can take between 4.5 kW and 12 kW of PV input and convert it to an AC output of 3 kW to 8 kW. The new products feature a maximum efficiency of 97.6%.
Tecnalia, Vita International developing solar guardrails
Spain’s Tecnalia and Italy-based Vita International have designed a new photovoltaic guardrail, set for testing later this year on a 100-meter stretch of a highway service area between Turin and Trieste, Italy.
Ultra-short-term PV forecasting based on convolutional neural network, long short-term memory
Scientists have created a novel probabilistic model for 5-minutes ahead PV power forecasting. The method combines a convolutional neural network with bidirectional long short-term memory, attention mechanism, and natural gradient boosting.
I, Photovoltaics
New research from Germany has investigated for the first time the idea of building a photovoltaic Dyson sphere, a theoretical megastructure that could provide vast amounts of energy for interstellar space travel and large-scale technological endeavors. Despite its highly theoretical and science-fiction inspiration, the study explains what consequences a similar construct would have on life on Earth.
Alumina oxide nanoparticles extend perovskite solar cell lifetime
Scientists in the U.K. have used alumina oxide in perovskite solar cells to achieve lifetimes exceeding 1,300 h under standards-based heat and humidity testing. Their analysis showed that a reference cell based on conjugated polyelectrolytes degraded in one-tenth the time.
Vaillant, Fraunhofer ISE present residential heat pump with new safety concept
The novel heat pump system relies on a thermal sensor based on an adsorbent-coated sensor layout developed by Vaillant in cooperation with the Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE). This technology is reportedly effective in preventing propane from forming an ignitable mixture with air outside the device.
Home batteries vs. power generators
Assessing the difference in cost, functionality and operations of fueled generators versus home batteries.
Triple Solar unveils PVT-assisted heat pump using waste heat from PV
Triple Solar BV has developed a residential photovoltaic-thermal (PVT) heat pump that uses waste heat from PV modules, eliminating the need for an outdoor unit.
