Ecoppia Deploys Autonomous, Water-Free Cleaning System For Negev Solar Park


Israel-based Ecoppia has deployed a water-free cleaning system at the 4.95 MW Ketura Sun solar park in Israel's Negev desert, jointly owned by Siemens AG and Arava Power.

Ecoppia's E4 cleaning robots use a microfiber and air flow cleaning system. The systems operate on frames that traverse the surface of the array. Each robot has its own solar panel for self-charging.

Following a pilot installation, the company says nearly 100 centrally controlled E4 robots currently clean the 18,500 Suntech panels in the array every night. Prior to the installation of the cleaning system, Ecoppia says the Ketura array was manually cleaned about nine times per year, with each process requiring five days.
