Solstice, Satcon s distributed energy management system, is an optimized end-to-end, panel-to-grid, solar P electrical power generation system that focuses on improving total system performance, reducing overall balance of system costs and increasing system controllability, safety and uptime. Solstice is engineered from the ground up to provide granular control over every component in the array from a single string, to the inverter, to power delivered to the grid. With its sophisticated central command and control center, Solstice reacts to changing conditions with remarkable speed, providing the industry s first complete power harvesting and management solution for utility-class power plants. Solstice breaks a large array into small strings of well matched modules and harvests the energy on the DC end in order to optimize the performance of the entire array. By introducing fine-grained energy production, including string-level MPPT, Solstice delivers higher energy yield, ensuring that the negative effects of shading, soiling and aging mismatch are localized and minimized while also being identified and reported. Advanced Power Plant Control Capabilities On the DC side, string-level instrumentation can be used to manage the array and trend its performance, providing visibility to poorly behaving elements of the array, including ground currents. This enables centralized management and maintenance of the array and improves both day-to-day performance and safety.

2 Solstice 100 kw UL ntelligent and Flexible Satcon Solstice enables centralized, intelligent management of the entire P system along with the flexibility of localized control over every component in the array, from the panel, to a single string, to the inverter, to the grid thus serving as a total system solution. How Solstice Works n any system, individual string curves are seldom identical due to shading, soiling or other causes of module mismatch. n a centralized system, this results in each string operating below its maximum power point, leading to suboptimal energy production from the whole system.
