# Perfect for distributed PV operations at any scale PV Go O&M system is designed to solve the pain points of most large-scale PV operation. As PV plants grow, operators will see a huge decline in system performance as data grows, especially when their PV plants are distributed across different geolocations. As a result, the latency will increase and data loss will significantly impact operational efficiency. Our PV O&M system fundamentally solves these issues through an intelligent data-management system. It delivers the same performance for PV operations of any size or distribution. # PV energy output optimized by AI Photon’s AI engine learns from historical and real-time data to predict PV energy output with 95 % accuracy for the next 5 minutes. PV operators can plan energy exchange and manage risk more effectively with this capability. # O&M Ticket Dispatch System Data-backed visualizations improve decision-making and shorten response times. An experienced service manager can locate the problem within a few seconds through our system. Inexperienced starters can achieve the same results as other team members when looking for solutions. # Real-time data in GUI • Topology view to monitor every detail of a PV operation • Video streaming (HD) to enable surveillance functionality (available on request) • Heatmap view to visualize the energy-output efficiency of each PV plant
