STP255 - 20/Wd

Product catalog summary

Features and Performance:
The 255 Watt Polycrystalline Solar Module by Suntech offers excellent performance under weak light conditions with a positive power tolerance of 0/+5%. It is designed to maximize system output by reducing mismatch losses up to 2% through Suntech's current sorting process. The module is certified to withstand extreme wind (3800 Pascal) and snow loads (5400 Pascal). It achieves a high module conversion efficiency of up to 15.7% through advanced cell technology.

Warranty and Reliability:
The module comes with an industry-leading warranty, guaranteeing 97% nominal power in the first year and a maximum decrease of 0.7% per year, ending with 80.2% in the 25th year. It also includes a 10-year material and workmanship warranty. The module is PID resistant, ensuring high resistance to potential-induced degradation.

Certifications and Standards:
The module conforms to IEC 61215, IEC 61730, and CE standards. It is tested for harsh environments, including salt mist, ammonia corrosion, and sand blowing, ensuring durability and reliability.

Design and Installation:
The module features a compact and durable frame design, making it lightweight and easy to handle. The IP67 rated junction box supports installations in multiple orientations, ensuring maximum output. The module's mechanical characteristics include polycrystalline silicon cells, anodized aluminum alloy frame, and tempered glass.

Electrical Characteristics:
At Standard Test Conditions (STC), the STP255-20/Wd model has a maximum power of 255 W, an optimum operating voltage of 30.8 V, and an optimum operating current of 8.28 A. The module efficiency is 15.7%. At Nominal Operating Cell Temperature (NOCT), the maximum power is 188 W.

Packing and Dimensions:
The module dimensions are 1640 × 992 × 35 mm, and it weighs 18.2 kg. It is packed with 30 pieces per pallet and up to 840 pieces per 40' HC container.
