Researchers present inverter-based dust monitoring method for rooftop solar
Researchers in China have developed a dust monitoring technique that relies solely on the existing hardware resources of inverters, without requiring extra sensors or meteorological data. Tests on existing rooftop PV arrays demonstrated an accuracy exceeding 96%.
Researchers test solar panel cooling using stagnant water layer
Researchers have developed a stagnant water layer cooling concept and tested it using seawater, tap water, and desalinated water. The panel temperature decreased by up to 8.2 °C, while power output increased by approximately 28%.
Building-integrated concentrating photovoltaics for vertical applications
An Indian-British research team has developed a building-integrated linear concentrating PV facade by sandwiching an asymmetric compound parabolic concentrator, PERC cells, and encapsulation layers between two sheets of glass.
New algorithms boost dual-axis solar tracker performance
Researchers in Australia and India have developed two solar tracker optimisation techniques that can purportedly increase power generation by up to 54.36% when combined. One uses a light sensor and the other relies on data from GPS and a real-time clock.
Enphase presents bidirectional EV charger
The microinverter company has disclosed details on the architecture of its IQ Bidirectional EV Charger, which will be available for sale in the second half of 2026. It is reportedly able to deliver up to 11.5 kW of bidirectional power.
