  • Efficiency of 21.8% matches the TOPCon 400-450W median
  • At 217.6 W/m² power density, roof space requirements are typical for TOPCon 400-450W panels
  • -0.31%/°C temperature coefficient - 0.02pp worse than TOPCon 400-450W median (-0.29%/°C), expect higher hot weather losses
  • 24.0 kg weight exceeds %!s(float64=2.1999999999999993) median by %!f(string=T) kg (21.8 kg) - heavier for installation crews
  • #5704 for efficiency, #6513 for temperature performance out of 11672 panels

Show series description

The HT-SAAE HT54-18X(ND)-F series are modern full-black modules, seamlessly combining aesthetics with genuine performance in Polish conditions. The application of N-type cells in TOPCon technology helps mitigate typical power degradation over time and enhances installation stability, which is particularly important with rising energy costs and net-metering considerations.

This series is available in the form of dual-glass construction and bifacial design, enabling the panel to utilize light reflected from the ground surface as well. This translates to higher energy yields, especially where every additional kilowatt-hour counts – on rooftops with limited space, when installed on light-colored roofs, or on the ground.

Their advantages over many competitive modules also include resistance to micro-cracks and quality control in the form of double EL testing, reducing the risk of hidden defects after transportation and installation. The HT54-18X(ND)-F series is an excellent choice for homes, small businesses, and projects where appearance, durability, and reliable performance matter.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
