Bosch unveils residential heat pumps based on inverter ducted split tech
The new product series uses R-454B as the refrigerant and is available in four versions.
Ecuador could host floating PV facilities at 11 hydropower plants
An international team has researched the potential to deploy floating photovoltaics at hydroelectric stations in Ecuador, finding 11 out of 70 sites that could host at least 15 MW up to 200 MW.
Colored modules for building-integrated photovoltaics
Taking inspiration from the 3D photonic structures on a Morpho butterfly’s shimmering blue wings, scientists at Germany’s Fraunhofer Institute for Solar Energy Systems ISE have developed colored solar panels that can be incorporated into a building’s exterior practically invisibly while maintaining high efficiency.
MIT engineers say solar, batteries could stabilize grid after cyberattacks
Researchers from the Massachusetts Institute of Technology (MIT) say that residential solar panels, batteries, electric vehicles, heat pumps, and water heaters could all form part of a local electricity market to restore power or ease grid stress following cyberattacks or severe weather conditions.
Weil-McLain launches dual-fuel heat pumps for residential, light commercial applications
The US-based heating specialist said its new air-to-water heat pumps use difluoromethane as the refrigerant and have a coefficient of performance of up to 5.37.
New method to predict solar module lifespans under sand erosion
A team of researchers in Algeria has designed a new testbed and a novel acceleration law that accounts for both wind speed and sand density. The new methodology was tested on four PV modules and showed lifespans of up to 47 years in terms of sand impact.
TU Delft research suggests back contact tech may push crystalline silicon PV over 28% threshold
Researchers in the Netherlands have investigated how carrier-selective contacts may help achieve stronger performance in back-contact (BC) crystalline silicon solar cells and have predicted efficiencies may reach up to 28.64%. Their analysis considered work function, energy barriers, and energy alignment across the stack of layers.
The Hydrogen Stream: Spanish government allocates €1.2 billion for renewable H2 clusters
The Spanish government allocated €1.2 billion ($1.26 billion) for seven green hydrogen clusters concentrated in Aragon and Andalusia. Meanwhile, an EU consortium started its work to develop diagnostic and monitoring tools for water electrolyzers.
Polyshine Solar unveils ultralight, flexible rooftop solar panels
The Chinese manufacturer said its new flexible modules have an efficiency of up to 20.1% and a weight of only 7.5 kg, or 2.92 kg/m2. The new products have purportedly a light transmittance of over 91% and “ultra-high” UV blocking ability.
Lennox debuts residential heat pump for cold climates
The company says that its new SL22KLV heat pump system can supply heat in temperatures as low as -28.9 C. It uses R-454B as the refrigerant and has a size ranging from 2 tons to 5 tons.
