How to Use This Calculator
- Enter the total DC capacity of the solar array in kW (sum of all panel wattages).
- Set the DC-to-AC size ratio (clipping ratio) — typically 1.1–1.3 for optimized systems.
- Input the maximum power temperature coefficient of the panels.
- Review the recommended inverter AC output capacity in kW.
- String inverter sizing must also account for voltage (Voc) and current (Isc) limits — confirm with the manufacturer.
