China’s Sol-Bright introduces automated robotic cleaning system for utility-scale solar plants


Beijing-headquartered Sol-Bright Technology Co. Ltd, the world’s largest manufacturer and supplier of automatic robotic cleaning systems (ARCS) for solar panels, has introduced its Gen.6 Robot for utility-scale solar projects in India.

The Gen.6 ARCS features a lightweight design, a skeleton made of aluminium to minimize chances of corrosion and rusting and a curvilinear body to withstand high wind.

“The robot uses gear transmission, unlike the chain and sprocket mechanism used conventionally. It provides four different levels of protection. Cleaning efficiency is more than 99.5%. Availability is also more than 99%. So, if you have bought 100 robots, out of 100 only one robot will go under breakdown at one point of time,” Kumar Shailendra, Country Head, Sol-Bright Technologies India, told pv magazine.

Shailendra said Sol-Bright Technology has shipped solar panel cleaning robots for around 17 GW of PV projects around the world, out of which systems equivalent to 6 GW are deployed and operating in India.

The robot uses a roller brush rotating at a speed of 130±10 rpm to dry-clean the panels.

“The robot can handle land undulations up to 15 degrees. The torsional structure allows it to twist from zero to forty degrees while walking,” said Shailendra.

The Gen.6 ARCS measures 2,500x418x238 mm and weighs 47±1.5 kg.
