As a kind of green and clean energy, the photovoltaic industry has become a strategic emerging industry that the city vigorously developed in recent years. From solar cells, inverters to PV modules and other ancillary products, the city has built a complete industrial chain covering all areas of photovoltaic industry production; from the family rooftop power station to the Yuguang complementary large-scale ground power station, the field of photovoltaic applications in our city is also Constantly broadening; from the earliest promotion of subsidies to build smart energy platforms in the country, the city has continuously launched the nation's first initiative in the field of photovoltaic development. The photovoltaic industry has become an “industrial card†displayed by Hefei.
The rapid development of one hundred photovoltaic industry chain enterprises Qi polymer fertilizer
In recent years, the city has gathered nearly 100 households in the photovoltaic industry chain and 26 companies in the company through attracting and guiding and nurturing.
Driven by large companies, the photovoltaic industry has developed rapidly. From 2013 to 2016, the output value reached 14.276 billion yuan, 24.647 billion yuan, 30.927 billion yuan, and 39.9 billion yuan respectively. In particular, the rapid growth of more than 20% has been maintained in the past three years. In 2016, the output value of China's photovoltaic industry exceeded 300 billion yuan. The PV industry in our city achieved a production value of 39.9 billion yuan, accounting for 12% of the country's total. Among them, JA Solar’s ​​output value exceeded 10 billion yuan, and Sunlight’s power and Tongwei’s solar energy output exceeded 6 billion yuan and 5 billion yuan respectively; Sunlight Power has the world’s largest PV inverter shipments for two consecutive years; Tongwei Hefei’s base has become a global leader. The largest single crystal silicon solar cell production base.
During the “Thirteenth Five-Year Plan†period, the city will also focus on promoting 15 major PV investment projects with a total investment of 12.47 billion yuan. After these projects are put into production, the city’s photovoltaic capacity will be further expanded and further progress will be made toward the goal of “building China's first photovoltaic cityâ€.
Innovation is more than the PV pioneering model
In 2013, the city selected five households of peasant families in Luojiabang Village, Linhe Township, Feidong County, to pilot the “photovoltaics to the countrysideâ€. Since then, Hefei has opened the curtain of photovoltaic poverty alleviation. This kind of photovoltaic poverty alleviation model is still the first in the country.
From the initial personal photovoltaic power station to the village collective photovoltaic power station, the city’s efforts in poverty alleviation by PV increased and the coverage increased. At present, the city has a total of 5,649 grid-connected photovoltaic power stations for poverty alleviation and 214 power plants for poor villages. It is estimated that by the year 2020, the number of grid-connected PV power stations for the whole province will reach 9,700, benefiting about 26,000 poor households and 2602 poor villages, injecting new vitality into the increase of farmers' income and rural economic and social development.
In the policy area, the city is also constantly introducing innovations. Following the introduction of the first-degree electricity subsidy policy in the country, this year the city also introduced a method of energy-saving trading (for trial implementation), which allows photovoltaic power generation to use its own part of the transaction to gain profits, which is the first of its kind in the country.
At present, the distributed smart energy innovation platform that our city is building will be another breakthrough for the city in the field of photovoltaics. Through the innovation platform construction, we will attract industry-leading research teams to achieve key energy challenges, demonstrations, promotion and applications, and promote the development of smart energy industry.
The effect highlights economic and ecological benefits to achieve a win-win situation
The development of the photovoltaic industry has not only added strong driving force for the city, but also gained more ecological benefits.
"For a long time, our city's energy consumption varieties have become excessively dependent on coal, accounting for as much as 70%. In recent years, the city has vigorously promoted the application of clean energy such as solar energy and achieved remarkable results in optimizing the energy structure." .
In 2013, the city was included in the first batch of distributed photovoltaic power generation demonstration areas. After three years of development, the proportion of clean energy consumption in the city's total energy consumption in the city reached 15% in 2016, an increase of nearly 8 percentage points from 2010, of which photovoltaic power generation made a great contribution. During the summer peak season this year, the PV power plant's maximum power generation output reached 703,000 kilowatts, accounting for 10.4% of the city's summer's maximum power load, providing a strong guarantee for Hefei and even the province's economic and social development.
According to statistics, as of the end of September, the city's PV accumulated 1.55 billion kwh, saving about 450,000 tons of standard coal, and reducing 1.16 million tons of carbon dioxide. The promotion and application of photovoltaic power stations has helped the city to successfully obtain approval for the national pilot cities for new energy and low-carbon cities, and has won the title of “Comprehensive Model Cities for Energy Conservation†in the province.
Antenk DVI Series Digital Video Interface connectors are the standard digital interface for flat panels, video graphics cards, monitors and HDTV units.

Each version features our specially designed contacts which improve signal performance and a zinc alloy shield that reduces electromagnetic interference (EMI).
Digital Visual Interface Cable Connectors
DVI ConnectorWith the advent of technologies such as DVD players, high-definition televisions, and even digital cable, the need for more advanced cables and connectors has increased. Digital Visual Interface (DVI) is one response to the growing need for interconnected systems, enabling digital systems to be connected to an array of displays. Yet DVI cables and connectors can also be complicated, and may lead to confusion between High Definition Multimedia Interface (HDMI) and DVI. Although the two systems have much in common, they service different niches of digital technology.
Digital Visual Interface
Older systems aren`t necessarily outdated systems. Although DVI preceded HDMI, it`s still widely used in both business and domestic settings. DVI connectors are designed to handle digital data transmission, incorporating three transmission channels in every connector link. The maximum bandwidth for data transfer is 165 megahertz, which is enough to relay up to 165 million pixels per second. Data is encoded for effective transfer, but a single link can handle around 4.95 gigabits per second of information. Double links can handle twice that amount.
Because a DVI cable carries information over a 165 megahertz bandwidth, complete digital resolution can be obtained. Using double link connectors increases the speed of transmission, but requires another cable. However, not many devices depend solely on a double link DVI, so this technolgy can be used on an as-desired basis.
Types of DVI Connectors
There are three general categories of DVI cable connectors: DVI-Digital (DVI-D), DVI-Integrated (DVI-I), and DVI-Analog (DVI-A). However, most connectors fall into one of the first two groups.
A standard DVI Connector is 37 mm wide and has 24 pins, 12 of which are used for a single link connection. When analog is involved, four additional pins are needed to support the additional lines of an analog signal. It is not possible to cross from a digital source to an analog display or vice versa. In those instances, an integrated connector is probably the best option. There are five common types of DVI connectors.
DVI-I Single Link
This kind of connector has three rows, each with six pins. There are two contacts. Because the connector is integrated, it can be used with both analog and digital applications.
DVI-I Dual Link
A DVI-I dual link connector can also be used with both digital and analog applications, but is configured with more pins to accommodate a dual connection. There are three rows with eight pins each, as well as two contacts.
DVI-D Single Link
Specifically designed for digital applications, a DVI-D single link connector has three rows of six pins, and looks much like a DVI-I single link connector. However, a DVI-D connector has no contacts.
DVI-D Dual Link
Also made specifically for digital applications, a DVI-D dual link features more pins (three rows of eight) for dual connections. Like a DVI-D single link, a DVI-D dual link connector has no contacts.
DVI-A
This particular type of connector can only be used for analog applications, and has three rows of pins. One row has five pins, one has four pins, and the last row has three pins. Like single link connectors, a DVI-A link connector has two contacts.
