Trimark was on-site demonstrating the human-machine interface (HMI) component of their supervisory control and data acquisition (SCADA) systems. These systems are rack-mounted and touted for their flexibility to integrate with asset owners’ existing data acquisition frameworks.
The units feature uninterrupted power supplies, routers, and firewalls, all designed to comply with the North American Electric Reliability Corporation’s (NERC) stringent standards for data security hardening. Notably, some units are enhanced with controls that are only accessible locally via a secondary optical network. A representative highlighted that Trimark’s systems are deployed across some of the nation’s largest solar power plants, often customized at each inverter and linked through extensive on-site optical networks.
Illustrating the versatility of SCADA in action, the Solar-LIT booth presented its solar panel cleaning system, which operates autonomously and is driven by SCADA systems. These robots, powered by solar energy and supplemented by internal batteries, conduct their cleaning operations predominantly at night. The booth highlighted Solar-LIT’s involvement in a substantial 900 MW project in the UAE, where a single unit is able to clean between one and two megawatts of solar modules per evening. Additionally, the system can be expanded with a larger battery to increase capacity.
Optimized for specific layouts, the cost-effectiveness of these robots is notable, with expenses below half a cent per watt. Furthermore, the design allows the units to traverse between module racks via connecting tracks, enhancing operational flexibility.
