SHANGHAI, April 18, 2026 /PRNewswire/ — JinkoSolar, the world’s leading supplier of photovoltaic systems and ESS, has officially launched a lightweight module solution specifically designed for low-load roofs: the lightweight, high-strength Jinko “Light Diamond” 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 to conventional double-glazed modules (12.2 kg/m²);
Maximum power: 560 W;
Maximum module efficiency: 24.94%
Applications: Suitable for old factory buildings, temporary structures, light steel roofs, power plant coal sheds and buildings with load restrictions.
Five key benefits:
Advantage 1: Ultra-light with guaranteed resistance
JinkoSolar’s lightweight, high-strength “Light Diamond” modules weigh just 7 kg per square meter, representing a weight reduction of more than 40% compared to conventional double-glass modules. The total module weight for a 1 MW project is only 28.6 tonnes, a reduction of approximately 20 tonnes compared to double-glazed BC modules. This means that a large number of roofs that previously required reinforcement or were unsuitable for installation can now be directly equipped with solar panels without any structural modifications.
Advantage 2: 24.94% high efficiency – lightweight and high performance
A common flaw in most lightweight modules on the market is that they prioritize weight reduction over power production efficiency. JinkoSolar’s lightweight, high-strength “Light Diamond” modules break this compromise.
JinkoSolar’s lightweight, high-strength “Light Diamond” modules offer a maximum power output of 560 watts and an ultra-high efficiency of 24.94%, while flexible modules or BC composite modules only reach 450-460 watts, a single module power increase of over 100 watts. This means that a larger capacity solar power plant can be installed on the same roof area. More importantly, the higher power output directly leads to system cost optimization: fewer modules are needed, reducing balance of system (BOS) costs for mounting structures, cables, combiner boxes and other components; installation time is shortened, reducing labor costs; and overall BOS costs are further reduced by 3-5% compared to conventional lightweight solutions.
This is not a lightweight module born from compromise, but a high-efficiency module that takes performance to the next level.
Advantage 3: Reduced weight without compromising on quality, backed by a 30-year power warranty
The main concern with lightweight modules is whether their reduced weight compromises reliability. JinkoSolar’s lightweight, high-strength “Light Diamond” modules address this concern with technology and data.
In terms of structural reinforcement, the modules use lightweight 1.6mm glass to reduce weight while maintaining light transmission; the frame features a reinforced channel design with increased thickness, improving overall mechanical strength; and the encapsulation process uses reinforced adhesive film, significantly improving sealing performance, moisture resistance and heat resistance, as well as micro-crack resistance.
In terms of load certification, the maximum load capacity on the front side is 3600Pa, which is equivalent to withstanding 3.6 meters of snow accumulation, and the module can withstand the impact of 25mm hailstones without damage. The maximum load capacity at the rear is 2400 Pa, which is equivalent to withstanding category 12 winds. In the face of extreme weather conditions, it provides a robust safety barrier.
In terms of long-term reliability measurements, the temperature coefficient is -0.26%/°C, which results in lower power generation losses at high temperatures; the output power warranty extends over 30 years, 12 to 15 years longer than that of flexible or composite modules; first-year degradation is no more than 1%, with an annual degradation of 0.35%, both of which exceed industry averages.
Benefit 4: Save money, time and effort
The lightweight design of JinkoSolar’s lightweight, high-strength “Light Diamond” modules not only reduces physical weight, but also systematically optimizes total life cycle costs.
Compared with conventional module reinforcement solutions, JinkoSolar’s lightweight and high-strength “Light Diamond” modules save about 0.5 yuan per watt in reinforcement costs, which is equivalent to a saving of about 500,000 yuan per MW. The construction period is reduced from over 40 days to 8-10 days, a reduction of 75%. There is no need to stop production, avoiding operational losses, and the approval process is simplified, eliminating the need for structural change approvals.
Taking a 1 MW project as an example, the savings in reinforcement costs amount to about 500,000 yuan, the construction period is shortened by more than 30 days, and the avoided losses during production shutdowns – which can reach hundreds of thousands of yuan depending on the size of the company – significantly increase the internal rate of return (IRR) of the project and significantly shorten the payback period. For renovation projects involving older factory buildings, the biggest advantage of Jinko’s lightweight, high-strength “Light Diamond” modules is that installation can continue without interrupting production; businesses can maintain normal operations while the solar power plant is installed on the roof simultaneously, ensuring that both goals are met.
Advantage 5: Strong demand, a blue ocean market
According to industry statistics, China has more than 6 billion square meters of 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 exceeding 300 billion yuan.
The renovation of old factory buildings, the modernization of cultural and creative parks and distributed solar systems on thin steel roofs: these scenarios that were previously unsuitable for installation are now becoming a new blue ocean for the growth of photovoltaics. Whoever is the first to offer truly reliable products will be able to conquer this market.
Application scenarios
1) Renovation of old industrial buildings: This is the main application scenario. Industrial buildings constructed in the last century, as well as power plant coal sheds, carports and simple rural supermarkets, often have limited load-bearing capacity and structurally deteriorated roofs that cannot safely support additional weight. Jinko’s lightweight, high-strength “Light Diamond” modules can be installed without structural reinforcement and do not disrupt production during renovation, making them the preferred solution for green renovation of old industrial buildings.
2) Cultural and creative parks and commercial complexes: With insufficient roof bearing capacity, the need to maintain operations and aesthetic requirements, Jinko’s lightweight and high-strength modules “Light Diamond”, which are lightweight, efficient and reliable, are very suitable for these scenarios.
3) Light Gauge Steel Roofs and Color Coated Steel Sheet Roofs: Light gauge steel roofs, commonly used in modern industrial facilities, inherently lack sufficient bearing capacity. Jinko’s lightweight, high-strength “Light Diamond” modules, weighing just 7 kg per square meter, enable the installation of solar panels on these roofs.
4) Special buildings with load restrictions: such as space frame structures, arched roofs and agricultural greenhouses, Jinko’s “Light Diamond” lightweight and high-strength modules can easily adapt to these structures.
