New algorithm for fault detection in renewables microgrids
An Iraqi-Canadian research team has created a new algorithm that can detect direction change in the line current of renewables-based microgrids. The novel approach can be applied to both grid-forming and grid-following infrastructures.
Canadian startup unveils substring inverter prototypes
Daanaa says its news Zodiac substring inverter delivers up to 42% more energy than a regular setup.
Strawberry fields forever, and with transparent PV
Scientists have grown strawberries under thin-film cadmium telluride panels with varying transparency. They found that 40% transparency maintained a greater than 80% yield of uncovered plants. If all strawberry farms in the world were converted to agrivoltaics, they would produce up to 173 TWh a year.
New method to predict potential induced degradation in glass-glass TOPCon solar modules
A research group led by Chinese manufacturer Trina Solar has outlined a new approach to predict potential induced degradation (PID) in dual-glass solar panels under multiple typical field conditions. The novel methodology is claimed to facilitate simultaneous PID and light exposure.
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.
