Cooling solar modules with vacuum pressure
Scientists in Indonesia have developed a vacuum technique to lower the temperature of PV modules below the ambient air temperature. They applied it to a solar module in a casing that is resistant to negative pressure.
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.
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.
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.
PV shade screens for greenhouses, agrivoltaics
A Saudi Arabian startup has developed a modular solar panel for agrivoltaic applications. It is specifically designed for locations with high solar radiation levels and protects plants and crops from excess sunlight.
How variable is rooftop solar power?
A research group has developed a new methodology that shows PV systems located in the same area could have similar distributions of power ramps. Their three-step method could be used for the dimensioning of rooftop arrays and the scheduling of daily operations.
