20GW of Signed Contracts Prove the High Reliability and Investment Value of 182mm Modules

By Jinko Solar

With the advent of the “14th Five-Year Plan”, the PV industry has continued its rapid development, with large-size modules progressively gaining popularity in the market – indeed, according to industry expectations, the production capacity of 182mm modules may exceed 100GW by the end of 2021. There are three leading companies in the industry which have each already signed orders for over 20GW of 182mm modules to be supplied to some 30 countries and regions around the world. Thanks to the 182mm module’s high power class and system-friendly advantages, it is likely to win a high percentage of market share and may become the mainstream choice of the market. The high market acceptance of the 182mm module is not only because of its technical and performance advantages, but also due to various application scenarios and access conditions. Its size provides benefits from the perspective of installation, transportation, system matching, operation and maintenance and security. 

JinkoSolar has collaborated with Shanghai Electric and other well-known domestic EPCs and design institutes to jointly develop a series of applied solutions. These include the “JinkoSolar Tiger Pro Module System Design Application and Economic Feasibility Study Report”, a calculation of 182mm module design schemes by multiple system equipment suppliers under specific application scenarios. The report provides owner, EPC and customer with a reference for the total cost and LCOE, which assists module selection. After accurate calculations, the report shows that the Tiger Pro module series is compatible with all mounting systems and can maintain high power output in high wind load environments. Furthermore, Tiger Pro modules provide an excellent economic performance. In many project fields, compared with conventional modules, Tiger Pro shows a higher return on investment and lower costs, maximizing profitability for both investors and developers.

The company has also combined the “Specifications for the Efficiency of PV Power Systems in China” with China’s unlimited DC/AC ratio policies, conducting a logical analysis of projects that use Tiger Pro modules to formulate the “Optimal DC/AC Ratio Scheme for China’s PV Projects.” According to existing projects, the current DC/AC ratio in China is generally below 1.5. After calculations based on actual projects, the following conclusions are drawn: The performance of string inverters is improved when equipment input is fully connected, significantly reducing the construction cost of a project when the degree of peak cutting of string inverter equipment has not changed to a great degree. For centralized inverters, under the premise of the best yield rate for projects, if we take into account fixing the DC side and variable AC side, the DC/AC ratio of a lower radiation area can reach 1.45 and above, with a higher radiation area in the range of 1.3-1.4; if we fix the AC  and variable DC sides, the DC/AC ratio corresponding to the optimal rate of return can be improved still further.

JinkoSolar has formally announced that “the company will continue to optimize manufacturing processes as well as carrying out technological innovation, and will also expand customer value-added service systems to lead the technological development of the PV industry. JinkoSolar will continue to provide extremely reliable modules and quality services to bring greater value to our end customers.”
