Graphene has extraordinary electrical conductivity, strength tens of times greater than steel, and excellent light transmission properties. Graphene has a perfect two-dimensional plane structure, which is the source of its rich and novel physical phenomena.
How to prepare high quality, large size and low cost graphene on a large scale is an urgent problem to be solved in industrialization. Despite the rapid advancement of graphene research in the scientific community, which has attracted investment and attention, researchers are still cautious about its industrialization.
Why is the photovoltaic industry short of money? The reasons seem to be no less than several aspects: 1. Blind expansion leads to overcapacity. 2. Bank loan collection. 3. Malicious competition causes prices to fall too fast. 4. US-EU anti-dumping; the present and future layout needs funds.
Recently, the State Council has issued the "Eight Articles of the State" to support the photovoltaic industry, and the following rules may be followed by the pricing of photovoltaic power stations in different regions, the start of pilot projects in demonstration zones, and grid support for the development of the photovoltaic industry.
Firstly, if a single small distributed photovoltaic system is connected to the grid, the grid enterprises need to send people and spend 12,000 yuan on evaluation, acceptance, commissioning and other grid-connected costs are relatively high. The capacity of grid enterprises is limited. If a large number of distributed systems appear all over China, it is believed that free grid connection will soon become the past. In addition, distributed encouragement of self-use not only attracts part of the customer group of power grid group, but also strongly supports the opponents of power grid enterprises at their own expense. The photovoltaic industry is too wishful-minded.
Photovoltaic industry is a strategic emerging industry, which has been considered as a sunrise industry. This view makes many photovoltaic companies unwilling to quit in difficult times. We are waiting in torment. However, will warm spring come after winter?
When the photovoltaic industry had a smooth road in the past few years, the local government did not want to vigorously develop this new industry, and gave many preferential policies on land, tax, banking and credit. The photovoltaic development zones and industrial parks were blooming all over the country. The investment policy of "going up fast" has led to a rush of photovoltaic enterprises. Blind construction and extensive expansion have led to serious overcapacity.
The photovoltaic industry has experienced several crazies from the most developed and best investment in the initial stage to the current crisis. Domestic market demand is slow, a large number of photovoltaic capacity can not be consumed, for a time, overcapacity has become the biggest original sin. So, what causes the overcapacity of photovoltaic industry?
In order to reduce costs and avoid price constraints, more and more domestic photovoltaic enterprises are keen to build factories overseas or look for OEMs. In fact, there are not many successful cases for domestic photovoltaic enterprises to build factories overseas. There are great risks in building factories overseas and it takes a long time to invest. Moreover, in order to prevent malicious acts, the European Commission intends to strengthen the supervision of Chinese photovoltaic enterprises through overseas base activities.
For a long time, the unwelcome embarrassment of China's photovoltaic industry is quietly changing. On August 30, the National Development and Reform Commission promulgated three new policies to support photovoltaic power plants. Domestic photovoltaic applications finally ushered in spring.
Recently, the National Development and Reform Commission (NDRC) has repeatedly put forward new policies to boost the photovoltaic industry, making it clear that the new ground power stations will be subdivided into benchmark stations with a minimum price of 0.9 yuan/degree, distributed photovoltaic power stations will be subsidized with a power subsidy of 0.42 yuan, and renewable energy additions will also rise from 8 centimeters to 15 centimeters. The market believes that this subsidy is stronger than the industry expected, will greatly stimulate the domestic demand market, domestic photovoltaic enterprises will soon spend the winter. However, the author believes that whether the current situation of overcapacity can be truly digested and China's photovoltaic domestic demand market can be revived still needs timely follow-up from various aspects.
How to apply for the family photovoltaic power generation project? The reporter interviewed the power experts of Taiyuan Power Supply Company on the issues of public concern. Citizens apply for installation before other owners agree to the Taiyuan Power Supply Company staff told reporters that family photovoltaic power generation project for roof area requirements, if the applicants live in their own villas or self-built houses in rural areas, then can meet this condition, then only to issue a certificate permitting the installation of residential property.
