MUNICH, Might 11, 2025/ PRNewswire/– On Might 7, 2025, LONGi, a worldwide leader in solar innovation, released a premium back contact module EcoLife series based upon heterojunction (HBC) at Intersolar, Munich This is the very first time that heterojunction back contact innovation has actually been effectively executed in a commercialized module.
27.3% cell effectiveness and module effectiveness as much as 25%
The EcoLife series module provides a world-leading cell effectiveness of 27.3% and a module effectiveness of as much as 25%, setting a brand-new standard for efficiency in the photovoltaic market. The very first released module variation is the 54-cell bifacial premium, and more variations will be launched consequently. The 54-cell bifacial premium module released on Intersolar is created for usage in the property sector and has an optimal power output of as much as 510W, resulting in a power per square meter ratio of 250W/m TWO.
EcoLife series, an exceptional brand name established particularly for the property sector, are created to satisfy the innovative expectations of property owners, integrating high efficiency with improved security, long-lasting dependability, and a structured visual fit to compact roof environments. With EcoLife series, LONGi intends to develop closer connections with end clients and make it possible for a more nimble, in your area responsive technique to item advancement, service shipment, and brand name engagement in crucial property markets.
Very first commercialized PV module based upon HBC platform
The EcoLife series includes the world’s only mass-produced HJT + BC cell innovation, which integrates the high-efficiency passivation of heterojunction (HJT) with the multi-surface light absorption of back-contact (BC) styles. This leads to full-surface passivation from all angles, minimizing metal recombination loss to absolutely no and making it possible for open-circuit voltage surpassing 750mV.
Compared to mainstream modules, the EcoLife series provides 40W greater output and can increase roof setup capability by as much as 9%, strengthening LONGi’s position at the leading edge of solar development.
Constructed on the HBC platform, the EcoLife series makes sure exceptional energy generation and dependability as the very first of its kind in mass production. It includes an ultra-low temperature level coefficient of -0.24%/ ° C, restricting efficiency losses under high-temperature environment. Deterioration is simply 1% in the very first year, followed by a best-in-class 0.35% yearly rate. Engineered for durability, it stands up to snow loads up to 4 meters (6000 Pa) and Classification 15 typhoon winds (3600 Pa) and holds a Class A fire ranking for top-tier security.
TaiRay wafer and Anti-shading make sure improved security functions
LONGi’s exclusive TaiRay wafer boosts the module’s mechanical strength, increasing rupture resistance by 16% and minimizing surface area collapse under tension. The complete back contact one-line welding structure lowers cell edge tension, enhancing the module’s anti-cracking efficiency.
In addition, the wafer is 10 μm thicker than other choices, supplying improved dependability and durability. The module likewise includes bipolar passivation innovation on its front, sides, and back. Combined with the Anti-shading style, compared to conventional TOPCon cells, under the very same shading conditions, the regional temperature level is decreased by 28% (comparable to 38 ° C). This substantially reduces the development of locations and lowers the likelihood of fires triggered by them.
Backed by a 30-year power and product service warranty, the EcoLife series are dedicated to long-lasting, conserve efficiency in the property circumstance.
EcoLife Series readily available in bifacial complete black and transparent
- LR7-54HJBB– A 54-cell complete black bifacial module with an optimum effectiveness of 24.7% and 505W Pmax, created for exceptional aesthetic appeals and efficiency.
- LR7-54HJD– A 54-cell transparent bifacial module with 25.0% optimum effectiveness and 510W Pmax, using high energy yield and advanced security functions.

Due to the nature of back contact innovation, both modules are crafted for optimum efficiency in low-light conditions, making sure optimum energy autonomy for homes, even in shaded locations or with minimal roofing system area.
The EcoLife Series will be readily available in August throughout Europe this year.
