LONGi, the world leading solar technology company headquartered in Xi’an, China, has officially launched its new 66C type Hi-MO 4 monofacial PV module (Hi-MO 4m) for the global distributed generation (DG) market.
With an area of about 2 m2, weight of 22kg and power of 410-420W, the new module can be widely used on rooftops in residential, industrial and commercial applications.
In early 2019, LONGi launched its Hi-MO 4 series high-efficiency PV modules for full scenario applications based on the M6 (166mm) standard monocrystalline wafer and PERC technology.
Within a year of mass production, the Hi-MO 4 series achieved the remarkable milestone of 10GW in global shipments, gaining wide industry acceptance and confidence.
As the world approaches the era of grid parity in 2021, LONGi has re-focused on the specific demands of the DG market with a view to delivering value for customers in the sector with new innovative products.
In addition to 66C, the Hi-MO 4m series also offers 60C and 72C types. These three products cover power ranges of 370-385w, 410-420W and 450-460W, with maximum efficiency of up to 21%, providing DG users with wider flexibility and options.
With high performance and an aesthetically pleasing appearance, the Hi-MO 4m module combines the advantages of high efficiency, high energy yield and high reliability. Its size and weight are designed to match the requirements of DG system installations and application scenarios.
For the residential market, the Hi-MO 4m 60C module (area of 1.82 m2, weight of 19.5kg, width of 1.04m) is most suitable in terms of convenient installation due to its moderate size and weight.
In some countries and regions, modules of larger size and weight can also be installed on residential roofs. LONGi therefore also provides 66C (22.0kg) and 72C (23.5kg) options.
The width of the module is standardized, while three different length options allow the Hi-MO 4m series to maximize the photovoltaic system’s installation capacity in residential rooftops.
The Hi-MO 4m 72C type module is suitable for use on industrial and commercial roofs.
In terms of installation type, in addition to tiling installation on inclined roofs and installation with the optimal inclination angle on flat roofs, the “4-point installation on short frame” on flat roofs is adopted in some developed countries for lower installation cost and improved system capacity.
In this special application scenario, the Hi-MO 4m 66C format module outperforms other modules. Compared with conventional module products, it not only achieves stable and efficient power output, but also has higher resistance to wind and snow loads.
Distributed generation products can be considered key in enabling PV to enter thousands of households and the high value of the Hi-MO 4m series modules will offer global DG users new choices and flexibility, matched with high quality and value.
In terms of electrical matching, the current at maximum power of the Hi-MO 4m module is lower than 11A, which is a perfect match for the various brands of string inverters, power optimizers and micro inverters available worldwide.
It not only makes full use of the design margin of the equipment, but also avoids the loss of power generation or mismatch caused by current limiting.
LONGi modules are known for their excellent energy yield performance and product quality, aspects which have been validated by the global market and authoritative third-party institutions:
- In PV Magazine tests, the outdoor energy yield of LONGi’s monofacial and bifacial modules was significantly higher than that of similar products;
- In outdoor energy yield simulations under TÜV Rheinland’s “All Quality Matters” evaluation, LONGi has won awards in numerous consecutive years, securing the award in 2020 for both monofacial and bifacial module groups.
- In the 2019 Renewable Energy Test Center (RETC) PV Module Index report, LONGi was one of only two high achiever companies, by virtue of the reliability, performance and quality of its products. In 2020, LONGi became the only manufacturer to achieve excellence scores in all eight test indicators.
In order to serve its global distributed generation customers more efficiently, LONGi will expand the capacity of its dedicated DG production line to 10GW in 2021.
