Solstice

The industry's first complete power harvesting and management solution for utility-class solar power plants.

Solstice®, Satcon®'s distributed energy management system, is an optimized end-to-end, panel-to-grid, solar PV 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.

• Boosts total system power production by 5-12%
• Lowers overall balance of system costs by 20-25%
• Reduces installation time & expense
• Enables string-level power optimization & centralized total system management
• Delivers advanced grid interconnection & utility control capabilities
• Increases system uptime, safety & reliability

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.

The Next Generation of Large-Scale Solar

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.
