JinkoSolar officially launched a lightweight module solution specifically designed for low-load-bearing roofs--the Jinko 'Light Diamond' lightweight, high-strength module, based on its Tiger Neo 3.0 technology platform. Module weight: 16.2 kg. Module dimensions: 1980 × 1134 × 30 mm.

Weight density: 7 kg/m²-- 40% weight reduction compared with conventional double-glass modules (12.2 kg/m²). Maximum power: 560 W. Maximum module efficiency: 24.94%. Applications: Suitable for older factory buildings, temporary structures, light-gauge steel roofs, power plant coal sheds, and buildings with load restrictions.

JinkoSolar's 'Light Diamond' lightweight, high-strength modules weigh only 7 kg per square meter, representing a weight reduction of over 40% compared to conventional double-glass modules. The total module weight for a 1 MW project is only 28.6 tons, a reduction of approximately 20 tons compared to BC double-glass modules. JinkoSolar's 'Light Diamond' lightweight, high-strength modules deliver a maximum power output of 560 watts and an ultra-high efficiency of 24.94%, whereas flexible modules or BC composite modules only reach 450 to 460 watts--a single-module power increase of over 100 watts.

This means a higher-capacity solar power plant can be installed on the same roof area. The higher power output directly leads to optimized system costs: fewer modules are required, reducing Balance of System (BOS) costs for mounting structures, cables, combiner boxes, and other components; installation time is shortened, lowering labor costs; and overall BOS costs are further reduced by 3% to 5% compared to conventional lightweight solutions. The modules utilize 1.6mm lightweight glass to reduce weight while maintaining light transmittance; the frame features reinforced channel design with increased thickness, enhancing overall mechanical strength; and the encapsulation process uses reinforced adhesive film, significantly improving sealing performance, resistance to humidity and heat, and resistance to micro-cracks.

The maximum front-side load capacity is 3,600 Pa--equivalent to withstanding 3.6 meters of snow accumulation--and the module can withstand impacts from 25mm hailstones without damage. The maximum back-side load capacity is 2,400 Pa, equivalent to withstanding Category 12 winds. The temperature coefficient is -0.26%/°C, resulting in lower power generation losses at high temperatures; the power output warranty spans 30 years, which is 12?15 years longer than that of flexible or composite modules; first-year degradation does not exceed 1%, with annual degradation of 0.35%, both of which outperform industry averages.

Compared to conventional module reinforcement solutions, JinkoSolar's 'Light Diamond' lightweight, high-strength modules save approximately 0.5 yuan per watt in reinforcement costs, equivalent to a savings of about 500,000 yuan per MW. The construction period is reduced from over 40 days to 8?10 days--a 75% reduction. There is no need to halt production, thereby avoiding operational losses, and the approval process is simplified, eliminating the need for structural modification approvals.

Taking a 1 MW project as an example, the savings on reinforcement costs amount to approximately 500,000 yuan, the construction period is shortened by more than 30 days, and the avoided production downtime losses--which can reach hundreds of thousands of yuan depending on the company's scale--significantly boost the project's internal rate of return (IRR) and markedly shorten the payback period. For retrofit projects involving older factory buildings, installation can proceed without halting production; companies can maintain normal operations while the solar power plant is installed on the roof simultaneously. According to industry statistics, China has over 6 billion square meters of existing commercial and industrial rooftop space, with load-restricted roofs accounting for more than 30% of this total--representing a potential market of nearly 2 billion square meters.

Based on an installation density of 100 watts per square meter and a system cost of 1.5 yuan per watt, the theoretical installation capacity exceeds 200 GW, with a market size surpassing 300 billion yuan. Industrial buildings constructed in the last century, as well as power plant coal sheds, carports, and simple rural supermarkets, often have limited roof load-bearing capacity and structurally deteriorated roofs that cannot safely support additional weight. Jinko's 'Light Diamond' lightweight, high-strength modules can be installed without structural reinforcement and do not disrupt production during renovation.

With insufficient roof load-bearing capacity, the need to maintain operations, and aesthetic requirements, Jinko's 'Light Diamond' lightweight, high-strength modules--which are lightweight, efficient, and reliable--are a perfect fit for these scenarios. Light-gauge steel roofs, commonly used in modern industrial facilities, inherently lack sufficient load-bearing capacity. Jinko's 'Light Diamond' lightweight, high-strength modules, weighing just 7 kg per square meter, enable the installation of solar panels on these roofs.

Special buildings with load restrictions, such as space frame structures, arched roofs, and agricultural greenhouses, Jinko's 'Light Diamond' lightweight, high-strength modules can easily adapt to these structures.
