310W LONGi Solar Panel is a highly efficient, low LID Mono PERC 120 cell module that represents the latest half-cut technology. It features black 40 mm frame, black backsheet, 1200mm cables, MC4 connectors, and industry-standard -0/+5W sorting.

LONGi's latest advance in module technology, the HPB series, boasts excellent low light performance and reduced PID susceptibility. Max DC System Voltage: 1000V Center Mounted J-Box.

Higher Efficiency of up to 19.3%

Great power output and greater energy yields. Outstanding power output in low light conditions, such as dawn, dusk and cloudy day, with relative average efficiency of 97.5% or better. Positive tolerance of maximal power guaranteed (0~+5W).

High Efficiency at High Temperatures

The low thermal coefficient produces greater energy production at high operating temperatures. The module provides a high energy yield at low NOCT = 45°C ( ±2°C).

Quality and Reliability

High-quality assurance due to stringent quality control. Greatly reduced PID susceptibility. .

Slow Power Degradation

A low 0.55% annual degradation rate after an initial first-year degradation of less than 2% is made possible due to low LID Mono PERC technology and results in a performance guarantee no less than 84.7% of the nominated power by year 25.

Enhanced Frame Design

The module’s 40 mm frame design provides easy installation and ensures robust mechanical strength. It is able to withhold a heavy snow load up to 5400 Pa and wind loads up to 2400 Pa. This module passed rigorous ammonia and salt mist resistance tests, which makes it an excellent choice for installations in harsh environments such as farms and seaside. This module is adaptable for the installation in hot and highly humid areas.

10 Year Product and 25 Year Performance Warranty

This module comes with a 10-year product warranty on materials and processing and a 25-year extra linear power output warranty.
