Seven Years of Wind and Snow - A Record of a Seven Year Old Photovoltaic Power Station in Grevat

Stability is the key to achieving the ultimate goodness. In the long river of time, people and things are changing, but the standards of quality will not change. The power station that has been running smoothly for seven years at Grevat still shines brightly after the baptism of time. Dunhua City, located in Yanbian Korean Autonomous Prefecture, Jilin Province, is known as the "thousand year old capital and hundred year old county". It is the birthplace of the Qing royal family, the founding capital of Bohai Kingdom in the Tang Dynasty, and carries the meaning of promoting morality and customs. Here, you can gaze at the silver clad Changbai Mountain while immersing yourself in the Bohai Lake, listening to the stories of Bohai, experiencing history, and returning to simplicity. The high-quality geographical location and lighting resources make Dunhua the preferred location for green energy bases. A seven year old power station using the Gurewat solution is located in this white snow. The power station was built in 2015 and is located in the central eastern part of Dunhua City. It is now in its seventh year of stable operation. The power station adopts the popular model of Growatt 30KTL3-SE inverter from 2014 to 2018, with an installed capacity of 150kW and a cumulative power generation of about 1.38 million kWh in seven years. In 2015, the understanding of photovoltaic power generation in China was not sufficient, but Wang Yuanzheng, an installer in the northeast region of Guriwatt, and his partners began their journey of "chasing the light". To solve the problem of high heating costs for greenhouse vegetables in winter, Wang Yuanzheng suggested that farmers install photovoltaic power stations and use environmentally friendly and economical solar energy to solve pain points. This power station is one of the earliest photovoltaic+agricultural projects, with a 200 meter photovoltaic corridor that optimizes traditional heating methods such as coal burning and plastic film that are not environmentally friendly and convenient enough. In winter, the power station uses photovoltaic power generation to heat vegetable greenhouses, keeping the temperature inside the greenhouse at around 20 ℃, meeting the temperature conditions required for vegetable growth. In addition, it can also meet the irrigation needs of farm vegetables and generate additional economic income by connecting surplus electricity to the internet. Combining photovoltaics with agriculture to achieve the integration and innovation of ecological agriculture and circular agriculture technology models, providing strong technical support for sustainable agricultural development. Photovoltaics have revitalized the most traditional agriculture with new vitality. Dunhua City is located between 42 ° and 44 ° north latitude, and the lowest winter temperature can reach minus 28 degrees Celsius. For the past seven years, Grewatt inverters have been operating normally in harsh environments such as low temperatures and cold winds, adapting to complex application scenarios and ensuring safe, reliable, and stable operation. Seven years of wind and snow invasion, more than two thousand days of full-time power generation, time has helped us verify the quality.
