LONGi Launches Next-Generation EcoLife Solar Module

On May 7, 2025, LONGi, a prominent name in the solar technology realm, made waves at Intersolar Munich with the introduction of its innovative EcoLife series. This series marks a pivotal moment in solar energy, presenting the first commercially available back contact module utilizing heterojunction (HBC) technology. With a staggering cell efficiency of 27.3% and module efficiency reaching 25%, the EcoLife series is poised to redefine performance standards in the photovoltaic sector.

Unparalleled Efficiency and Design

The initial release of the EcoLife series features a bifacial module with 54 cells, designed explicitly for residential applications. This version can generate power outputs as high as 510W, offering a remarkable power-to-area ratio of 250W/m². Long recognized for innovation, LONGi aims to enhance user experience with this new line by providing a product that meets the sophisticated demands of homeowners. The blend of high-performance capabilities and an elegant design caters well to the compact aesthetics of modern rooftops.

Innovations in Solar Technology

The EcoLife series stands out not just for its efficiency but also for its groundbreaking HJT + BC cell technology. This combination allows for comprehensive surface passivation from all angles, effectively minimizing metal recombination losses to virtually nothing. As a result, this module boasts an impressive open-circuit voltage of over 750mV. What sets the EcoLife series apart further is its ability to outperform mainstream offerings by an impressive margin of 40W while potentially increasing rooftop installation capacity by as much as 9%. Such advancements underscore LONGi's leadership in solar innovation.

Robustness and Reliability

Durability and safety are critical with solar installations, and the EcoLife series delivers on both fronts. Featuring an ultra-low temperature coefficient of just -0.24%/°C, it is designed to retain optimal performance even in high-temperature scenarios. The degradation rate stands at a mere 1% in the first year, tapering to an industry-leading 0.35% annually thereafter. Engineered to handle extreme conditions, these modules are built to withstand snow loads of up to 4 meters and winds classified at Category 15 hurricane levels. Additionally, they are certified with a Class A fire rating, ensuring the highest safety standards.

Comprehensive Design and User Focus

LONGi has integrated several safety elements into the EcoLife modules. The proprietary TaiRay wafer improves mechanical strength, resulting in a 16% increase in rupture resistance, and a thickness that is 10 μm above conventional options. The unique design, which employs bipolar passivation technology across the structure, alongside Anti-shading features, enhances functionality even in shaded areas.

Varieties and Availability

The EcoLife series will come in two aesthetic options:

• - LR7-54HJBB: A sleek 54-cell full black bifacial module achieving a maximum efficiency of 24.7% and 505W Pmax for performance without compromising style.
• - LR7-54HJD: An attractive transparent bifacial variant boasting a maximum efficiency of 25.0% and 510W Pmax, designed for optimal safety and energy output.

The strategic engineering of the EcoLife modules enables them to excel even under limited sunlight conditions, ensuring energy independence for households. Launching in August 2025 across Europe, this series epitomizes LONGi's commitment to innovation and responsiveness to the evolving needs of the residential solar market.

Through the introduction of EcoLife, LONGi is not just offering solar modules; it is fostering a more intimate relationship with consumers, reflecting a dedicated, localized approach to product development and customer engagement. The future of solar energy has arrived, and LONGi is leading the charge.
