MUNICH,, May 12, 2025 / Prnewswire / – On May 72025, Longi, a world leader in solar technology, has launched a premium rear contact module Ecolife Series Based on heterojunction (HBC) in Intersolar, Munich. This is the first time that contact technology with the heterojunction back has successfully implemented in a marketed module.
27.3% cell Modula efficiency and efficiency up to 25%
The Ecolife series module offers cutting -edge cellular efficiency of 27.3% and a module efficiency of up to 25%, which defines a new reference for performance in the photovoltaic industry. The first version of the launched module is the bifacial premium at 54 cells, and other versions will be published later. The bifacial premium module at 54 cells launched on Intersolar is designed to be used in the residential sector and has a maximum power of up to 510 W, leading to a power ratio per square meter of 250 W / m².
The Ecolife series, a premium brand developed specifically for the residential sector, is designed to meet the advanced expectations of the owners, combining high performance with improved safety, long -term reliability and rationalized aesthetic adapted to environments on the compact roof. With Ecolife Series, LONGI aims to establish closer connections with end customers and to allow a more agile and locally reactive approach to the development of products, the provision of services and the commitment of the brand in the main residential markets.
First marketed PV module based on the HBC platform
The Ecolife series incorporates only HJT + BC cell technology produced in the world, which combines high-efficiency passivation of heterojunction (HJT) with the absorption of multi-surface light of rear contact conceptions (BC). This results in a complete passivation of the surface from all angles, reducing the loss of metallic recombination to zero and allowing an open circuit voltage exceeding 750 MV.
Compared to the general public modules, the Ecolife series offers 40 W higher and can increase the installation capacity on the roof up to 9%, strengthening the longi position at the forefront of solar innovation.
Built on the HBC platform, the Ecolife series provides higher energy production and reliability as the first of its kind in mass production. It has an ultra -low temperature coefficient of -0.24% / ° C, limiting performance losses in a high temperature environment. Degradation is only 1% in the first year, followed by an annual rate of 0.35% in the best class. Inigmated for resilience, it is resistant to snow up to 4 meters (6000 PA) and the winding winds in category 15 (3600 PA) and has a class A fire rating for high -level safety.
Tairay Wafer and Antihading ensure improved safety characteristics
The Tairay tranche owner of long improves the mechanical resistance of the module, increasing the breaking resistance by 16% and reducing the collapse of the under -stress. The welding structure in a complete contact line reduces the cellular edge stress, improving the module anti-dracking performance.
In addition, the slice is 10 μm thick than other options, offering increased reliability and longevity. The module also has bipolar passivation technology on its front, sides and back. Coupled with anti-shaded design, compared to traditional Topcon cells, under the same shade conditions, the local temperature is reduced by 28% (equivalent to 38 ° C). This considerably removes the formation of hot spots and reduces the probability of fire caused by them.
Supported by a guarantee of 30 -year -old power and equipment, the Ecolife series is engaged in the long term, except the performances in the residential scenario.
Ecolife series available in bifacial and transparent black
- LR7-54HJBB – A full black bifacial module at 54 cells with maximum efficiency of 24.7% and 505W PMAX, designed for aesthetic and higher performance.
- LR7-54HJD – A transparent bifacial module at 54 cells with maximum efficiency of 25.0% and 510W PMAX, offering high energy efficiency and advanced safety characteristics.

Due to the nature of the rear contact technology, the two modules are designed for optimal performance in low light conditions, guaranteeing maximum energy autonomy for houses, even in shaded areas or with a limited roof space.
The Ecolife series will be available in August throughout Europe This year.
