Competing PV+storage Architectures: Why Fixed-Voltage DC-Coupled Systems are Winning Markets

Synopsis

• Despite increasing adoption of co-located systems, there are considerable industry knowledge gaps about the fundamental differences between the three main solar+storage configurations and which is best-suited to deliver high performing, low cost utility scale PV+storage systems.
• A comparison on the advantages of a Fixed Voltage DC-coupled architecture over competing Variable DC-coupled and AC-coupled designs.
• Discussion around the rapid growth of Fixed DC-coupled solar+storage deployments around the world and how Ampt String Optimizers are enabling various use cases, including “storage as a transmission” assets, peak management, and grid resilience.
