Sol-Bright, an India-based provider of robotic solar cleaning systems, has signed a supply contract with Rays Power Infra, solar EPC and developer, for the NTPC Bikaner 250 MW solar PV project in Rajasthan. Under the agreement, Sol-Bright has been contracted to deliver fully automatic, water-free robotic cleaning systems designed for 1P tracker installations across the project site. According to the company, the systems have been engineered to support consistent module cleaning without water use, aligning with operational requirements in arid regions. Rays Power Infra is executing the project for NTPC at Bikaner, where large tracker arrays are planned. Commissioning has been scheduled for Q2 2026, when the robotic systems are expected to be fully integrated into routine plant operations.
