Product Summary

This is the LR8-66HGD-620M by Longi. It's a 620W BiFacial solar module designed to meet the needs of commercial & industrial solar projects, plus ground-mounted residential projects looking for a larger format module and reduced cost per watt. Longi is one of the world's leading wafer, cell, and module manufacturers - rest assured, this is an investment in performance you can trust.

Product Description

This module is one of Longi's Hi-MO 7 series - LONGi's latest generation of high-efficiency modules designed for the utility market. It boasts excellent power generation performance and product reliability, making it particularly suitable for applications with high albedo, high temperature, and limited space.

New Wafer Size
The Hi-MO 7 66c adopts LONGi n-type TaiRay silicon wafers (wafer size 182.2 × 210mm), LONGi HPDC cell technology, and SMBB technology. It is designed according to the optimal module size of 2382 × 1134mm, with a module power range of 610W-625W and corresponding module efficiency of 22.6% -23.1%. The first year degradation is 1%, and the annual degradation is 0.4%.

Improved Temperature Coefficient
The power temperature coefficient of Hi-MO7 product is -0.28%/° C, which is significantly lower than the TOPCon product on the market at -0.30%/°C. At the same time, the low voltage design of Hi-MO7 66c can save BOS costs such as brackets and cables in most applications, such as tracker scenarios and scenarios with conventional wind speed. Thereby achieving a lower LCOE and higher customer value.

Increased Cost Reduction
The Hi-MO7 66c module inherits the advantages of the Hi-MO7 products: a higher bifaciality of 80% and a superior temperature coefficient of -0.28%/°C. Additionally, the 66c module features characteristics such as low voltage and high current, which enable longer string number. This can lead to significant cost savings in most applications compared to 72c module.
