ABOUT US

Jiangsu Dongyun Photovoltaic Technology Co., Ltd. was established in 2009 with a registered capital of over 200 million yuan. The total area of the Jiangyin and Yangzhou factories is over300000 square meters, and the annual production capacity of photovoltaic modules is about 10GW. The production of large P-type components and large N-type components has received high praise from the market. The total number of employees worldwide is over 3000,Dongyun Photovoltaic utilizes its first mover advantage in component research and development to undertake the construction of various types of photovoltaic power stations worldwide. As of the end of 2023, we have undertaken the construction of over 2000 photovoltaic power stations of different sizes. We have rich experience in building and maintaining stations in different terrains, roofs, and scenarios, and have obtained multiple national patent technologies. At the same time, it is also a culmination of new energy fields such as wind energy, photovoltaic energy storage, solar lighting, and solar irrigation.

Dongjun annual production module 10GW/year, the construction of photovoltaic power station (EPC) 500MW/ year production of light storage off the grid more than 5300 sets/year

Produced more than 3,500 sets of light irrigation systems/year to achieve an annual output value of more than 10 billion yuan, making due contributions to double carbon emission reduction.

The company has set up a professional technical installation team for distributed photovoltaic, and has rich experience in the installation of power stations with different roof morphologies and different roof structures.

The company has established a remote fault monitoring system of the power station, which can monitor and alarm the various faults remotely in time, and send technicians to the house for maintenance in time

Power generation capacity advantage:

Compared with the array form on the cement flat roof or the rain-proof laying form on the color steel tile, the area of the component arrangement increases, the capacity of the power station also increases, and the power generation will increase accordingly.

Advantages of plant expansion:

Installing an additional layer of rain-proof photovoltaic on the cement flat roof can increase the plant area of one layer within the height specified by the government for office, dormitory, workshop, rental, etc.

Labor saving and money saving advantages：

Save color steel tile, provincial insulation layer, provincial color steel tile renovation, provincial roof waterproof treatment, provincial air conditioning costs, etc., in disguise to reduce production costs.

Photovoltaic energy storage system is a comprehensive energy system combining photovoltaic power generation system and energy storage battery system, which mainly plays a role in the power grid application of "load regulation, storage of electricity, with new energy access, make up for line loss, power compensation, improve power quality, isolated network operation, peak cutting and valley filling".

Photovoltaic energy storage system is mainly composed of solar panels, energy storage batteries, control systems, etc. Solar panels convert solar energy into electricity through the photovoltaic effect, and energy storage batteries store the energy to meet the demand for electricity at night or on cloudy days. The control system realizes the switch between photovoltaic power generation and mains power according to the load of the grid and the power condition of the energy storage battery.

With the ceiling configuration, professional qualification, professional construction, professional grid-connection, professional after-sales, manufacturer's price, for customers to create 30 years of sustainable and stable income photovoltaic power station.
