Conserving panels away from mud in massive photo voltaic farms could be a time-consuming, wasteful and expensive enterprise. A Sicilian expertise startup known as the Reiwa Engine has developed an autonomous robotic known as SandStorm to scale back upkeep and cleansing prices by as a lot as 80%.
Mud, grime or sand that settles on the floor of photo voltaic panels can considerably scale back their effectivity. Personnel at photo voltaic farms can restore full yield utilizing energy washers or drive tractors down the rows of panels whereas hydraulic brushes sweep away the grime, however valuable water assets are wasted and automobile operation causes emissions, plus there are labor and gas prices to think about as nicely.
A few years in the past, Enel Inexperienced Energy (EGP) started testing the primary robotic from the Reiwa Engine on the vitality firm’s Innovation Lab at Passo Martino in Sicily.
The SandStorm cleansing bot clears away mud and particles because it strikes autonomously alongside a row of panels, utilizing brushes as a substitute of water, and is ready to adapt to uneven panel alignment in addition to cross gaps of greater than 50 cm (19.6 in).

The motor-driven cleaner returns to its docking station when its batteries run low, or on the finish of its shift. It could actually additionally function in the course of the night time to keep away from shading the panels throughout productive hours.
Trials then moved to a 1-MW part of an influence plant at Totana in Spain, and EGP is now planning to roll out 150 SandStorm robots at photo voltaic farms in Totana and Las Corchas, representing a complete capability of 135 MW, with financing from Cycero permitting Reiwa to enter full manufacturing to fulfill service volumes.
The partnership has additionally not too long ago examined a transport robotic at its facility in Go Martino that makes it attainable for SandStorm cleaners to maneuver between rows of panels – “lowering the variety of robots required for every plant, and consequently, the operational complexity and the preliminary funding as nicely.”
