On December 10, 2019, chairman Cao Renxian specially invited many old employees with more than ten years. Under the common witness of all, five 1500V photovoltaic series inverters sg225hx customized with the classic orange red color of sunshine power supply were slowly driven out of the factory. Sunshine power is the world's first photovoltaic power plant parts manufacturer with a total sales volume exceeding 100 million kilowatts (100gw) (including photovoltaic modules, inverters, brackets, box transformers, etc.). A few days later, these inverters will be sent to the construction site, adding a new stroke to many classic solutions of sunshine power in the world.

In 2018, the global PV total installed capacity will be 506gw. With the increase of about 100gw in 2019, the historical delivery volume of solar power will account for one sixth of the global PV inverter market.

100gw, which can support five power stations with the same power of the Three Gorges Dam, can produce more than 129 billion kilowatt hours of clean power every year and reduce 103 million tons of carbon dioxide.

This is one of the most eye-catching battles in the century long war between mankind and climate change.

Great cause.

100gw photovoltaic Museum covered with "medals"

Even before the total shipment exceeds 100gw, sunshine power has already become the most widely used Inverter Manufacturer in the world: the 500kW inverter ten years ago is still in stable and efficient operation, and this year, the latest global largest series inverter sg225hx has been put on the market in batches. The integrity of "resume" is unprecedented. With complete types and specifications of inverters, full coverage of application scenarios, and iterative inheritance of products from previous generations, it is not only a museum of photovoltaic inverters in China, but also a chronicle epic of photovoltaic development.

In the past 22 years, photovoltaic inverters have covered 3kw-6.8mw, including household series inverters, medium power series inverters and large centralized inverters. On average, at least one new product is launched every year, and the technological innovation is carried out once every three months.

Box inverter is also a clear proof of the development of photovoltaic inverter in China. In 2011, China's first box inverter came off the production line in the sunshine power plant, replacing the traditional earth building. Then, through the application of new technology, topology optimization, function integration and other technologies, the company continuously invested and upgraded, and gradually reduced the floor area from the initial 20 square meters to 10 square meters, 7 square meters and 3 square meters. In 2017, sunshine power was released Sg1250ud has become the first centralized inverter that can be directly applied outdoors, reducing the cost of land, construction, operation and maintenance, and significantly shortening the construction period.

The voltage level has also increased from 600V to 800V and 1000V. Sunshine power first released China's first 1500V centralized inverter in 2015 and the world's first 1500V series inverter in 2016. In 2016, the 1500V inverter of sunshine power supply was applied in batch in Datong phase I leader project. By the first half of 2019, the global application of 1500 V photovoltaic inverter of solar power has exceeded 8 GW.

In the 100 MW solar power demonstration base, the world's largest comprehensive solar power technology demonstration test base, the 1500 V system helps the power station become the "king of power generation" with its advantages. According to the Yellow River Hydropower data report, in the accumulated unit megawatt power generation in 2018, among the 23 arrays of 23 kinds of inverters in the world, the solar power 1500 V power generation is the highest, which is about 2% higher than 1000 V on average. Datong Mingyang 50MW power station, which uses 1500V system on a large scale, has the highest cumulative power generation in the 50000 kW single project, which is about 8% higher than that of the power station with the same capacity.

It has passed several domestic high-intensity experiments with excellent results, such as high and low voltage ride through test, hidden standard test, etc. in some experiments, only sunshine power supply has passed the test.

In terms of "interaction" between inverter and power grid, sunshine power is leading for several years each time. It has gone through the stages of adapting to power grid, supporting power grid, and then energy balance.

From 5000 meters above sea level plateau to hot and humid salt fog, from desert to floating on water, the products cover many countries and all terrain in the world, and also witness the change of photovoltaic application and investment preference. The Dunhuang concession project and yundian toushilin photovoltaic project, which were put into operation in 2009, are still in stable operation, and the customers also sent a thank-you letter.

This is the best medal for engineering men.

Guangtu giant: a 22 year photovoltaic timeline

From the span of 22 years, sunshine power and Cao Renxian are the gnashing teeth struggle history of an ordinary university teacher who abandoned his pen and went into business. They are also an important symbol of the rise of China's photovoltaic industry and even China's great power.

The development history of Cao Renxian and Yangguang power supply has very detailed information, which will not be repeated here. I just feel that when he and his team are in the situation of "throwing away his iron rice bowl and going to the sea to start a business", "being despised by foreign peers", "going public in the cold winter" and "encountering industrial upheaval", he and his team are faced with a difficult choice; I'm also curious about how this young man and growing team can keep their original intention in mind at such historical nodes as "digging the first pot of gold", "winning overseas respect", "being crowned king" and "expanding power technology to the whole world".

During this period, the attitude of the outside world towards China's inverter has changed from disdain, suspicion, recognition, and finally to iron. Together with many excellent photovoltaic enterprises, this 100gw inverter equipment has won dignity for made in China.

For 22 years, the company:

(2002) participated in the national "power transmission to rural areas" project, and delivered solar power to the western regions without power; (2006) undertook the research and development task of large grid connected inverter, a key project of the National 863 program;

(2008) help Beijing Olympic Games;

(2010) contribute to the World Expo;

(2009) assist the grid connection of the first concession bidding project;

(2013) passed the Golmud Ulan low voltage ride through test, the only one in the industry without off grid;

(2015) leading the industry for 4 years, becoming the first one to pass the Tibetan standard test;

(2015) for the first time, a Chinese enterprise surpassed SMA and became the global inverter sales champion;

(2015) inverter efficiency exceeded 99%;

(2019) the first 100 millisecond frequency modulation and dynamic reactive voltage response test was successfully completed by using inverter

Mr. Wen Yang, a researcher in the Chinese Academy of Fudan University, once put forward a point of view that Chinese civilization is the only "vast land giant" in the world. The Chinese nation has a long civilization, a vast territory, ethnic integration, and a large population. Mr. Liang Qichao once described it as "great without friends": there is a great event that our ancestors have made continuous efforts in the past 5000 years, which is called "the expansion of the Chinese nation". It turns out that our Chinese nation, at first only a few small tribes, in Shandong, Henan and other places to get some base areas, thousands of years, slowly grow Long To grow into a great family and build a great country.

It is not too much to use this word to define the position of solar power in the photovoltaic industry.

In 2005, researcher Ma Shenghong from the Institute of electrical engineering, Chinese Academy of Sciences went to Gansu Province for research, and Cao Renxian accompanied him. He wanted to do a 1MW grid connected project in Dunhuang. "Later, people thought it was too small, and they prepared to make 5MW." This is where Dunhuang photovoltaic franchise bidding started, and it is also the earliest starting point for many Chinese photovoltaic people. Finally, two 10 MW concession bidding projects were launched in 2009, which laid the foundation for the industrial development.

Ten years later, Qinghai Geermu 500MW project jointly developed by sunshine power and Three Gorges new energy shocked the industry with the grid price of 0.31 yuan / kWh, and several industry leaders who could not sit still came to Cao Renxian for lessons.

Sunshine power, treasure manufacturer.
