445W Solar Module/Panel

• 445W rated maximum power with ±5% output tolerance
• Mono-crystalline silicon cells for high per-watt efficiency
• 49V open circuit voltage suits 48V and higher-voltage string designs
• 1500V maximum system voltage for modern utility-style architectures
• Low 42°C NOCT for strong hot-climate performance
• 20A maximum series fuse rating
• Class A application rating
• Full-size 72-cell format (2095 × 1039 mm)

The STP 445S is engineered for modern high-voltage string designs. With 49V VOC per panel, series strings reach working voltages that maximise MPPT efficiency on mainstream hybrid and string inverters.

• Designed for high-voltage string arrays (typically 10–16 panels in series)
• Matches the PV input range of 600V and 800V class MPPT controllers and inverters
• Low NOCT helps maintain output in high ambient temperatures
• Mono-Si cells deliver more consistent output under low-light conditions
• Standard 35mm anodised aluminium frame with compatible mounting hardware

Modern Residential Solar

Well-matched to residential 6–15 kW systems using 48V battery banks and string hybrid inverters.

Light Commercial Rooftop

Efficient output per square metre makes the STP 445S a solid choice for shop, clinic, and light-industrial rooftops.

Off-Grid & Hybrid Homes

High open-circuit voltage reduces the number of panels needed for a given array voltage, simplifying wiring.

Ground-Mount Arrays

Full-size 72-cell format is well-suited to standard ground-mount racking systems.
