Solar Energy Efficiency Systems Specialist (SEI) The SEI exam assumes a strong base in photovoltaic cell physics, inverter topologies, and energy storage mathematics. Most candidates come from HVAC, electrical trades, or renewable energy technician backgrounds where thermal and electrical systems overlap. Without baseline familiarity with AC/DC conversion and load calculations, you’ll find the performance optimization sections particularly demanding.
