The JA Solar 475W photovoltaic panel measures approximately 2,172 mm (85.5 inches) in length and 1,130 mm (44.5 inches) in width, with a slim profile of 35 mm (1.38 inches) thickness. This standard large-format design follows the industry trend for high-efficiency modules, weighing approximately 25.5 kg (56.2 lbs) for easier handling during installation.
At STC (Standard Test Conditions) of 25°C cell temperature and 1000W/m² irradiance, this panel achieves:
Requires minimum 0.8m clearance for airflow beneath modules when mounted on rooftops. The panel's mechanical load capacity withstands up to 5,400Pa snow load and 2,400Pa wind load – crucial for installations in regions like Scandinavia or mountainous areas.
Compared to Trina Solar's 470W Vertex series, the JA Solar module demonstrates:
Recent field data from Australian solar farms shows these panels maintain 98.7% power output after 5 years of operation, outperforming most IEC 61215 durability standards. As one installer joked: "These panels are like solar-powered tanks – they survive everything except maybe a direct meteor strike."
Compatible with all major racking systems including:
Requires 4-point clamping with maximum 150mm center-to-center spacing between mid-clamps. The panel's pre-drilled mounting holes accept M8 or 5/16" hardware following AS/NZS 1170 structural requirements.
