Solar Panel Longi Hi-MO X10 Scientist LR7-54HVD 495M - LR7-54HVD-495M

HPBC 2.0 (Hybrid Passivated Back Contact) places all electrical contacts on the module's rear side. The front remains free of busbars (0BB), so no cell area is shaded. This increases light yield and results in a module efficiency of 24.3% here.

The module is laminated on both sides with glass — 2.0 mm on the front and 1.6 mm on the back. This design permanently protects the cells from moisture and mechanical stress, enables bifacial power generation via the rear side, and forms the basis for the 30-year performance warranty.

A 495 Wp module in Austria delivers around 480 to 590 kWh per year, depending on location and orientation. At an electricity price of 25 ct/kWh, this corresponds to savings of approximately 120 to 148 euros annually per module — the bifacial rear-side yield can be even higher with bright mounting.

For a typical annual consumption of 4500 to 5500 kWh, approximately 10 to 14 of these 495 Wp modules are suitable. This results in a system output of around 5 to 7 kWp and, in combination with a storage system, covers a large part of self-consumption.

Yes. The module is approved for a maximum surface load of 5400 Pa and a wind load of 2400 Pa, thus withstanding high snow loads in mountainous regions. The stable glass-glass design and the moderate temperature coefficient of -0.26 %/°C ensure reliable yields even with strong temperature fluctuations.

Longi is one of the world's largest manufacturers of monocrystalline solar modules and wafers and is considered a technological pioneer in high-efficiency cell concepts. The Hi-MO series stands for powerful modules with high efficiency and long warranty periods.
