MUNICH<\/span><\/span>, May 12, 2025<\/span><\/span> \/PRNewswire\/ — On May 7<\/span>, 2025,\u00a0LONGi, a global leader in solar technology, launched a premium back contact module EcoLife series<\/b> based on heterojunction (HBC) at Intersolar, Munich<\/span>. This is the first time that heterojunction back contact technology has been successfully implemented in a commercialized module.<\/p>\n

27.3% cell <\/b>efficiency and module efficiency up to 25%<\/b><\/p>\n

The EcoLife series module delivers a world-leading cell efficiency of 27.3% and a module efficiency of up to 25%, setting a new benchmark for performance in the photovoltaic industry. The first launched module version is the 54-cell bifacial premium, and more versions will be released subsequently. The 54-cell bifacial premium module launched on Intersolar is designed for use in the residential sector and has a maximum power output of up to 510W, leading to a power per square meter ratio of 250W\/m\u00b2.<\/p>\n

EcoLife series, a premium brand developed specifically for the residential sector, are designed to meet the advanced expectations of homeowners, combining high performance with enhanced safety, long-term reliability, and a streamlined aesthetic suited to compact rooftop environments. With EcoLife series, LONGi aims to build closer connections with end customers and enable a more agile,\u00a0locally responsive approach to product development, service delivery, and brand engagement in key residential markets.<\/p>\n

First commercialized PV module based on HBC platform<\/b><\/p>\n

The EcoLife series incorporates the world’s only mass-produced HJT + BC cell technology, which combines the high-efficiency passivation of heterojunction (HJT) with the multi-surface light absorption of back-contact (BC) designs. This results in full-surface passivation from all angles, reducing metal recombination loss to zero and enabling open-circuit voltage exceeding 750mV.<\/p>\n

Compared to mainstream modules, the EcoLife series offers 40W higher output and can increase rooftop installation capacity by up to 9%, reinforcing LONGi’s position at the forefront of solar innovation.<\/p>\n

Built on the HBC platform, the EcoLife series ensures superior energy generation and reliability as the first of its kind in mass production. It features an ultra-low temperature coefficient of -0.24%\/\u00b0C, limiting performance losses under high-temperature environment. Degradation is just 1% in the first year, followed by a best-in-class 0.35% annual rate. Engineered for resilience, it withstands snow loads up to 4 meters (6000 Pa) and Category 15 hurricane winds (3600 Pa) and holds a Class A fire rating for top-tier safety.<\/p>\n

TaiRay wafer and Anti-shading ensure enhanced safety features\u00a0<\/b><\/p>\n

LONGi’s proprietary TaiRay wafer enhances the module’s mechanical strength, increasing rupture resistance by 16% and reducing surface collapse under stress. The full back contact one-line welding structure reduces cell edge stress, improving the module’s anti-cracking performance.<\/p>\n

Furthermore, the wafer is 10 \u03bcm\u00a0thicker than other options, providing enhanced reliability and longevity. The module also features bipolar passivation technology on its front, sides, and back. Coupled with the Anti-shading design, compared with traditional TOPCon cells, under the same shading conditions, the local temperature is reduced by 28% (equivalent to 38\u00b0C). This significantly suppresses the formation of hot spots and reduces the probability of fires caused by them.<\/p>\n

Backed by a 30-year power and material warranty, the EcoLife series are committed to long-term, save performance in the residential scenario.<\/p>\n
