LONGi Solar LR5-54HABB-405M 405Watt 108 Half-Cell Black Frame Bifacial Solar Panel

LONGi Hi-MO 5 | 405W Bifacial Dual-Glass Solar Panel

• The LONGi Hi-MO 5 405W is a dual-glass, bifacial panel that replaces standard plastic backsheets with a rugged glass-on-glass design for superior fire safety and moisture resistance. This 108-cell module uses Gallium-doped wafers to prevent power loss over time, ensuring your 30-year warranty delivers real, stable energy. While the front captures direct sun, the bifacial back harvests reflected light to boost your total yield, making it an ideal choice for high-efficiency residential or commercial setups. Its sleek, all-black frame offers a premium look that blends into your roof while standing up to heavy snow and wind loads.

Power (measured in watts) and efficiency (how well panels convert sunlight to electricity) are some of the most common metrics used to compare solar panel products. While they are not the only means of comparison, they are important determinants in how much electricity you can produce with a solar panel system. Metrics like power tolerance and temperature coefficient are also important ways to analyze the potential performance of solar panels under the different conditions they will experience over their lifetime.
