Cooling down photovoltaic panels with concrete
Scientists in Italy have proposed the use of radiative coolers made of cementitious materials to reduce the operating temperature of solar panels. The novel system configuration consists of a stack made by a reflector, a cement-based radiative cooler, and a bifacial solar cell.
Color-sensing tech to remove dirt from solar panels
South African researchers have developed a new cleaning system for solar panels that uses a color-sensing light-to-frequency converter to detect dirt. It can reportedly remove around 95% of the dust from a PV panel in less than a minute, at a lower cost than other systems.
Customizable sticker to turn solar panels into advertising billboards
An Italian startup has created a fully recyclable sticker that can be used to cover solar panels on rooftops or facades. It replicates high-definition images that can help to improve the aesthetics of solar arrays or turn PV facades into advertising billboards.
New foldable solar system for rooftop applications
German manufacturer Kopp has developed an easy-to-install, four-module foldable PV array. The system uses n-type TOPCon solar modules with outputs of 430 W and efficiency ratings of 22.02%
US to deploy 30 GW/111 GWh of grid-scale energy storage by 2025
The US energy storage market hit an inflection point in 2020. The Energy Information Administration expects the deployment of grid-scale storage to pick up over the next three years.
MIT scientists produce new organic photovoltaic fabrics
US researchers have developed a thin-film organic solar module on a vapor-deposited releasable substrate made of parylene. The device could be used as a wearable fabric, or to bring solar generation to remote locations.
PV system fires potentially exacerbated by gap between solar panels, rooftops
Norwegian researchers have published a new study showing that the space between solar panels and rooftop surfaces might play a critical role in contributing to PV system fires.
PV windows cut energy use by 40% in glazed buildings, says NREL
The US National Renewable Energy Laboratory (NREL) has shown that perovskite-based thin-film PV, transparent PV, and dynamic PV glazing technologies can reduce the energy use of glazed buildings by around 40% across eight regions in the United States.
Panasonic unveils vehicle-to-home system for PV-powered homes
Panasonic claims that its new vehicle-to-home system can increase the self-consumption rate of residential solar and storage capacity to 90%.
Hevel Solar unveils 450 W heterojunction solar panel with M6 cells
Russia’s Hevel Solar said its new modules are based on 166 mm x 166 mm half-cut cells. They reportedly have a bifaciality factor of 90% and a temperature coefficient of -0.26% per degree Celsius.
