Recently, the first lightweight photovoltaic module project of State Grid Ningbo Power Supply Company was put into operation in Ningbo Junling Mold Technology Co., Ltd. This project can not only install roofs of different styles, but also speed up construction and reduce material consumption, injecting new energy to achieve the goal of "double carbon".

It is reported that most centralized photovoltaic power stations are installed on the ground, while the application scenarios of distributed photovoltaic are mostly building surfaces. Traditional glass crystalline silicon modules have poor ductility and high requirements for installation sites. About 40% of industrial and commercial factory roofs lack bearing capacity and cannot safely and reliably support traditional glass modules of 15-20kg/m2, which limits the further development of distributed photovoltaic.

State Grid Ningbo Power Supply Company has effectively solved this problem with the weight of 3-5 kg per square meter by taking advantage of lightweight photovoltaic modules. This technology was developed by Shangmai (Shanghai) New Energy Technology Co., Ltd. This application in Junling Mold Technology Co., Ltd. is the first time that this technology was applied in Ningbo to build roof photovoltaic. "Last year, we planned to build rooftop PV, but the roof load limited the development of the project. The light PV modules solved our problems and provided a new way for our low-carbon energy construction." Introduction by the person in charge of Ningbo Junling Mold Technology Co., Ltd.

The lightweight photovoltaic uses single crystal silicon solar modules to replace glass and optimize the frame, which reduces the weight by up to 80% compared with the conventional glass modules. At the same time, the traditional support system is eliminated from sticking to the roof, which can save costs and achieve the effect of "no roof" and beauty. This time, the roof project of Ningbo Junling Mold Technology Co., Ltd. plans to build a photovoltaic power station with a total capacity of 226.8 kilowatts, and the photovoltaic power consumption of users is 99.8%. According to the calculation, the annual average energy consumption will be reduced by 10% under the condition of the spontaneous use of surplus power on the grid.

It is understood that Junling Mold has not only installed the distributed photovoltaic project, but also carried out the digital transformation of energy management, which has improved the energy management efficiency by 5%. The digital transformation and upgrading of the power distribution system have made up for the blank of energy digitization in the enterprise's digital factory. The energy saving rate of the enterprise's air compressor digital control system has reached 10%.
