Low-cost, portable sun-tracker for offgrid solar
Mauritian researchers have developed a solar tracker prototype that increases current by around 37%. The device uses a simplified and mechanical tracking system.
Germany’s first photovoltaic cycling path goes online
Badenova has installed 912 glass-glass PV modules along a cycling path in the city of Freiburg, Germany, as part of a new pilot project.
Study shows n-type bifacial TOPCon cells more prone to degradation than p-type
Dutch scientists have reported higher degradation risk for n-type TOPCon cells with EVA encapsulant due to potential moisture degradation. Front-side metallization makes n-type cells more vulnerable than p-type cells, according to damp heat tests.
PV-powered robotic lawn mower from New Zealand
Researchers from Massey University in New Zealand have developed a robotic lawn mower with three 50 W solar panels and a 20 Ah lithium-iron-phosphate (LiFePO4) battery. Two of the PV panels can be retracted and stacked inside the robot. They slide out when it needs to recharge its batteries.
Biden to maintain US solar tariff pause with veto
US legislators are moving to restore tariffs for the shipment of solar components from four major Southeast Asian nations, but US President Joe Biden will veto the move and maintain the pause on tariffs.
Solis unveils hybrid inverters for rooftop applications
Solis has released a new line of hybrid inverters in five different power output versions, ranging from 3 kW to 8 kW. The hybrid inverters can be used with either lithium-ion or lead-acid batteries, with a maximum charging and discharging current of 190 A.
Polysilicon prices fall 1.33% to six-week low of $37.218/kg
In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.
German startup unveils mobile, tiltable PV modules
Sinn Power is offering new tiltable solar panels for vertical PV systems in nature reserves and water-protection areas. They are not anchored to the ground and use a pendulum weight to return to their proper positions when hit by strong winds.
CATL launches 500 Wh/kg condensed matter battery
Chinese battery industry heavyweight CATL has unveiled a novel condensed matter battery technology with an energy density of up to 500 Wh/kg. The company said it can achieve mass production within this year.
