The project is interconnected under PG&E’s Renewable Energy Self-Generation Bill Credit Transfer (RES-BCT) Program, allowing electricity generated to offset consumption across up to 50 of EBMUD‘s electrical accounts .

Part Two: Technology Breakthroughs – Efficiency Records and Performance Optimization

2.1 The 2024 “Efficiency Leap”: TOPCon, HJT, and Perovskite Advancements

2024 has been dubbed the “efficiency explosion year” for solar technology, with silicon-based cells breaking through 27% efficiency and perovskite/silicon tandem cells reaching 34.6% .

Key Efficiency Milestones:

The shift from PERC to n-type technologies (TOPCon, HJT, IBC) represents a fundamental transition in the industry. SPIC‘s 2024 field test results from the Daqing platform showed that IBC and TOPCon modules outperformed PERC reference modules by 4.77% and 4.37% in energy yield per unit area, respectively .

2.2 Tracking System Performance: Data-Driven Optimization

SPIC’s three-year field test (2022-2024) on mounting structure performance at the Daqing National Photovoltaic and Energy Storage Field Testing Platform provides crucial data for optimizing solar farm efficiency .
