System size

How many panels are wired in series in one chain (string). Usually 8–20 for home systems.

How many parallel chains (strings) of panels go into one inverter input.

Site conditions

How panels are installed. Affects how hot the cells get in summer.

°C

The lowest temperature in your area in winter. Affects max voltage calculation.

°C

The highest temperature in your area in summer. Affects min voltage calculation.

Estimated cell temperature: 65°C

Production tolerance (IEC 62548)OFF

Apply worst-case Voc +3% and Isc +5% to account for manufacturing variance. Recommended for safety-critical designs.
