The first part of the series aims to help homeowners looking to embrace PV identify the best installers on the market.
US scientists claim 15-fold performance increase for solar thermoelectric generator
A research team have fabricated a solar thermoelectric generator (STEG) that is reportedly 15 times more efficient than current state-of-the-art devices by concentrating on the managing the hot and the cold sides of the device rather than its semiconductor materials.
Improving roll-to-roll slot-die coating via machine learning
University of Sheffield researchers developed a machine learning framework to improve coating properties in a roll-to-roll slot die coating process. The work is seen as an initial step toward broader use of machine learning and related technologies to assist with optimization.
SolarStratos reaches 8,224 m height
Swiss pilot Raphaël Domjan flew the SolarStratos solar-powered aircraft to 8,224 meters on Aug. 10, setting a personal record but falling short of the 9,235-meter world mark held by Solar Impulse.
Seasonally optimized PV panel tilt can boost yield by up to 9% in India
A new study investigates the seasonal optimization of PV module tilt angles to optimize the energy efficiency of solar PV plants in the Indian state of Rajasthan. The results reveal that dynamic tilt adjustments can significantly boost annual solar yield across diverse climatic zones.
