550W (540–560W): Common in commercial and industrial (C&I) projects. With dimensions of around 2.25–2.30 m × 1.13–1.14 m and a weight of 26–32 kg, they help reduce the number of panels required per installed kilowatt.
JA Solar 550W panels represent an excellent choice for both residential and commercial solar installations in 2025. The combination of high efficiency, competitive pricing, comprehensive warranty coverage, and proven reliability makes them a standout option in the premium solar panel market.
Independent testing shows JA Solar 550W panels perform well in high-temperature environments. At 25°C above standard test conditions (45°C cell temperature), power output typically decreases by approximately 8.75%, which is competitive with other premium panels.
JA Solar 550W panels are compatible with most standard mounting systems designed for framed solar panels. The 35mm frame thickness requires mounting hardware specifically designed for this dimension. Recommended mounting systems: Rooftop installations: Ground mount installations:
