JinkoSolar launched its Light Diamond lightweight module based on the Tiger Neo 3.0 platform
The module offers 7 kg/m² weight and reaches up to 560 W with 24.94% efficiency
It carries a 15-year product and 30-year power warranty, extending beyond typical lightweight designs
Distributed solar is playing a growing role in meeting energy demand closer to where it is consumed, especially in the commercial and industrial (C&I) sector. Many of these installations are planned on existing rooftops. However, a large share of these buildings have structural load limitations and cannot support conventional glass-glass modules. This is creating demand for lightweight solutions that can still offer high efficiency and long-term reliability.
JinkoSolar, a leading solar module manufacturer, introduced its Light Diamond lightweight, high-strength module based on the Tiger Neo 3.0 platform. The module weighs 16.2 kg and has a weight density of 7 kg/m², which is about 40% lower than that of typical double-glass designs. It measures 1,980 × 1,134 × 30 mm and delivers up to 560 W of power with a module efficiency of 24.94%, maintaining performance while reducing weight.
The module uses 1.6 mm lightweight glass along with a reinforced frame and encapsulation structure. It is rated for front-side loads of up to 3,600 Pa and back-side loads of 2,400 Pa. The temperature coefficient is -0.26%/°C. It carries a 15-year product and 30-year power warranty, extending beyond typical lightweight and composite designs. The company claims a first-year degradation of below 1%, followed by 0.35% annually.
The lower weight allows these modules to be installed on roofs that previously required structural reinforcement or were unsuitable for solar, says JinkoSolar. It adds that installations can proceed without structural modification and, in retrofit cases, without interrupting operations. The higher power output compared to conventional lightweight module designs helps reduce module count and associated system components, with the company indicating BOS cost savings of around 3% to 5%.
The module is aimed at older industrial buildings, light-gauge steel roofs, and other structures with load limitations. JinkoSolar says this lightweight module addresses the structural constraints of such rooftops, which often remain unused.
