How can smart inverters in the era of parity help reduce costs and increase efficiency of photovoltaic products?

       On November 19, 2020, the “OFweek 2020 (Eleventh) Solar Photovoltaic Industry Conference and Photovoltaic Industry Annual Selection and Award Ceremony” hosted by OFweek, China’s high-tech industry portal, was successfully held in Shenzhen.

       This conference attracted industry leaders such as photovoltaic material suppliers, module manufacturers, downstream power station project developers, photovoltaic application companies, investment and financing institutions and other industry leaders in the industry chain to participate. Zeng Jianyou, General Manager of the Photovoltaic Product Line of Shenzhen Hewang Electric Co., Ltd., gave a speech on “The 14th Five-Year Plan” Energy Reform How Smart Inverters Help Reduce Costs and Increase Efficiency of Photovoltaic Products.

       After multiple five-year plans, my country’s economy has developed tremendously. During the next 14th Five-Year Plan period, the electricity consumption of the whole society will continue to grow. At the same time, under the requirements of the energy transition, more renewable energy sources are needed. stand by.

       Zeng Jianyou said that no matter how the economy of my country and the world develops, it will not affect the power substitution. At the same time, as the installed capacity of photovoltaics in eastern and central my country increases, the proportion of distributed photovoltaics will also increase to a certain extent, so there is no need to worry about photovoltaics. Development prospects.

       Photovoltaic companies need to consider how to achieve the goal of reducing costs and increasing efficiency as wind power and photovoltaics enter the era of parity during the 14th Five-Year Plan period. Zeng Jianyou believes that reducing costs and increasing efficiency of photovoltaic systems requires the deep cooperation of the entire industry, including components, box transformers, cable supports and inverters.

       So how can inverters help reduce costs and increase efficiency? This requires six aspects including technological innovation, diversified product applications, diversified scenarios, smart operation and maintenance, improved product adaptability, and improved product capacity ratio. Zeng Jianyou said.

       In terms of technological innovation, continuous technological breakthroughs to improve product performance are one of the best ways to reduce costs and increase efficiency. In terms of diversified products, inverters must develop in the direction of large current, high power, large square arrays, and optical storage in the future. Therefore, there is no need for too diversified products, and more space can be reserved for inverters. Reduce research and development costs through mass production.

       In terms of scene diversification, the needs of different scenes should be considered at the beginning of product design to better achieve compatibility; intelligent operation and maintenance can significantly reduce the maintenance cost in the later period, and there is still a lot of room for improvement in software and hardware.

       In terms of product adaptability, products with high adaptability are also effective methods for reducing costs, and other components can be fully emulated. Finally, in terms of product capacity ratio, LCOE decreases as the capacity ratio increases, thereby reducing investment costs.

       As an important part of photovoltaic power plants, inverters have a great impact on the cost. In the past few years, my country’s inverter companies have made very brilliant achievements, and Hewang Electric is one of the best products. It is also a choice that enterprises cannot ignore.
