01
Define the application
Note residential, commercial, or utility context and the intended operating conditions.
System Planner
Use this straightforward planning sequence to bring site, electrical, and documentation questions into the same conversation.
Note residential, commercial, or utility context and the intended operating conditions.
Record geometry, climate, access, mounting assumptions, and regional constraints.
Bring array, voltage, inverter, and system-design questions to the technical review.
Identify which datasheets and applicable documentation need to be reviewed.
Selection note: TOPCon and heterojunction module choices involve supply availability, temperature behavior, degradation assumptions and bankability. Nominal power and module efficiency must be checked against the current datasheet, test conditions and the project-specific IEC 61215 / IEC 61730 requirements.
