The Longi 405W 54 CELL Solar Panel offers excellent performance with up to 20.7% efficiency. Ideal for residential applications, Longi solar panels also feature lower resistive loss with lower operating current, higher energy yields and lower operating temperature. Longi’s new optimized electrical design also reduces hot spot risk and allows for lower operating currents. Longi 405W 54 CELL Solar Panels come with aesthetically pleasing black frames that offer UV protection and protection from the elements. Another positive attribute of this type of solar panel is its efficient power production at lower tilt angles vs. standard panels. These panels are offer the superior performance of half-cell modules which maximize the amount of light PV cells capture, while also reducing the amount that is reflected. These also dissipate heat more efficiently, altogether boosting energy harvest. Another great feature of the Longi 405W 54 CELL Solar Panel is its longevity. Longi guarantee these solar panels will continue to perform at over 84% of their original capacity after 25 years! Longi solar panel performance characteristics over 25 years.
