Greenleap Robotics has built the Lotus A4000 cleaning robot with automotive-grade components to serve as a reliable way to clean solar panels in arid regions.
The solar cleaning system moves horizontally and cleans the panels vertically, while a patented auto-switch allows the robot to clean from either side of the module row, which the manufacturer said minimizes cleaning time. The device weighs up to 50 kg and has a cleaning speed of 22 m per minute.
French researchers have developed a machine-learning model to clean low-power PV projects and standalone solar arrays in rural areas isolated from the grid.
pv magazine’s Amjad Khashman has spoken to Chinese solar developer Jinko Power about negotiating the world record low price tariff agreed for electricity generated at the Al Dhafra solar project in Abu Dhabi.
