About product

350w LONGi 120 cell, b/b, 1200mm cables, MC4, 35mm frame.

The LONGi HPH Series combines High Efficiency, Low LID Mono PERC cells with Half-cut Technology.

This module series has a max system voltage of 1000V and a UL Type 4 Fire Rating. 35mm frames reduce weight while still providing the strength and resilience needed to rate 5400Pa for front side static loading and 2400Pa for rear side static loading, according to the LONGi 350w spec sheet.

Higher Efficiency

Higher module conversion efficiency up to 20.3%, according to the LONGi 350W datasheet. Higher energy yield with lower operating temperatures.

The LONGi LR4-60HPH ranks as all-round superior in the efficiency stakes. Similar efficiency ratings or greater only exist within the industry's elite. Great power output and greater energy yields. LONGi 350 watt solar panels provide outstanding power output in low light conditions, such as dawn, dusk and cloudy day. Positive tolerance of maximal power guaranteed (0~ 5W).

Quality and Reliability

Stringent quality control assures high quality of LONGi 350 watt panels. Solid PID resistance ensured by solar cell process optimization and careful module BOM selection.

Slow Power Degradation

Slow Power Degradation enabled by Low Lid Mono Perc technology. In the first year LONGi 350W solar panels lose no more than 2% and from year 2 to 25 the average degradation rate is 0.55% .

Enhanced Frame Design

The LONGi Solar 350W module’s 35 mm frame design provides easy installation and ensures robust mechanical strength. This module passed rigorous ammonia and salt mist resistance tests. This module is adaptable for the installation in hot temperatures.

Product warranty

This LONGi 350W model provides a 12-year product warranty for materials and processing and 25 year warranty for extra linear power output.

Our goal was to be able to remain in our home during the extended power outages after hurricanes strike our rural northern Florida area. Your company provides a high quality customer service. Keep up the great job.

I contacted A1 Solar store to get help with the design and cost of a solar system for a medium size home completely off the grid. They put me in contact with one of their design. These guys were the best salesmen I have ever dealt with. They were so helpful, knowledgeable, accessible, and professional that I never even looked at another solar company.
