Signed contracts with 20 GW prove the high reliability and high investment value of 182 mm modules
With the start of the 14th Five-Year Plan, the market for the PV industry has continued to warm and large modules are becoming increasingly popular in the PV market.
According to industry expectations, the production capacity of 182mm modules could exceed 100GW by the end of 2021, and the most sophisticated product capacity planning will meet the demand of the global market.
There are only three leading companies in the industry that have signed orders for 182mm modules over 20GW and are sold to nearly 30 countries and regions around the world.
Thanks to the high performance class of the 182mm module and the system-friendly advantages, 182mm modules have undoubtedly contributed a high percentage of the market share and have become the mainstream choice.

The high market acceptance of the 182 mm module is based not only on its technical and performance advantages, but also on the various application scenarios and access conditions that the 182 mm module offers from the point of view of installation, transport, system adaptation, operation and maintenance as well as security.
In particular, the increasing trend of variable costs such as shipping and labor is also factored into the variable factors of investment cost to provide customers with the best investment plan.
Case study of 182 mm modules in use
In one example of an investment plan, JinkoSolar worked with Shanghai Electric and other well-known domestic EPCs and design institutes to jointly develop a range of applied solutions.
These include the JinkoSolar Tiger Pro Module System Design Application Report and the Economic Feasibility Study Report, a computation of 182mm module design schemes by multiple system builders under specific application scenarios.
The report provides owners, EPC, and customers with a reference for total cost and LCOE that helps customers make module selection. After careful calculations, the report shows that the Tiger Pro series of modules is highly compatible with any mounting system and can maintain high performance in high wind load environments.

In addition, the Tiger Pro series of modules has excellent economic performance. In many project areas, the Tiger Pro range of modules has shown a higher return on investment and lower costs compared to traditional modules, thereby maximizing the interests of investors and developers.
In addition, the company combined the specifications for the efficiency of PV power systems in China with China's guidelines for unlimited DC / AC ratios, and performed a logical analysis of projects using Tiger Pro modules to determine the optimal DC / AC Formulate the ratio for China's PV projects.
According to the existing projects, the current DC / AC ratio in China is usually below 1.5. After the calculations based on actual projects, the following conclusions are drawn:
- String inverters perform better when the device input is fully connected, which can significantly reduce the cost of building the project, and the degree of tip cutting of string inverters has not changed much.
- In the case of the centralized inverters, given the best rate of return for projects, the DC / AC ratio of the lower radiation range can reach 1.45 and more and higher, if we consider the DC side and the variable AC side, the radiation area can be in the range of 1.3 to 1.4 lie. If we consider fixing the AC side and the variable DC side, the DC / AC ratio corresponding to the optimal return can be further improved.
“JinkoSolar will continue to optimize manufacturing processes and implement technological innovations as well as expand service systems with added value for customers in order to drive the technological development of the PV industry. The company will continue to offer extremely reliable modules and high quality services in order to offer our end customers more added value, ”said the solar company.
