For solar-powered investment, the owners of solar energy systems that reduce their energy consumption bills have a 28% lower price per kilowatt-hour. According to data from the Solar Energy Guide, the average cost for consumers to pay for solar PV installations is 4,445.95 pounds per kilowatt-hour. In October 2011, this price dropped by 27.87% to 3206.96 pounds.
Due to the unreasonable structure of the photovoltaic market, over-reliance on foreign markets has led to hundreds of Chinese photovoltaic companies. 89 Chengdu is relying on international sales, especially the European market. Over the past few years, both the industry leader and many small and medium-sized enterprises, they have not been very good at studying in depth how large-scale promotion and application of solar energy products in China's large cities and rural areas. Even the most familiar photovoltaic glass curtain wall has been talked for so many years. In major cities such as Shanghai and Beijing, it has hardly been used in new buildings and building remodeling. Imagine that everyone enthusiastically dreamed of gold rushes in Europe and the United States. They did not even take into account the risk of fluctuations in foreign markets and did not concentrate on opening up the domestic market.
On the one hand, it is due to the developed market economy and the necessity of capital for profit; on the other hand, it is also related to the overheating of the new energy industry in local governments. This phenomenon has occurred in many industries. However, it is believed that the overcapacity phenomenon in the photovoltaic industry in recent years has been particularly devastating, and it has also been related to the constant follow-up of domestic and foreign venture capital investment. This has led each PV company to hold its motives for making money in foreign capital markets. Interviewed with several private and small and medium-sized photovoltaic companies, they "have to say Nasdaq", all thinking "regardless of corporate profits, to overseas listed money to say." It is precisely this way that the bubbles in the Chinese PV industry are getting bigger and bigger. When the bubble bursts, it will inevitably spread even wider and hurt more. This point must be vigilant for any high-tech industry that is concerned by venture capitalists.
As the European debt crisis caused the shrinkage of solar energy markets in European countries, as well as the disorderly competition and capacity expansion in China's domestic market, the photovoltaic industry's revenue declined in recent months. The Chinese listed photovoltaic giants such as Trina Solar, Yingli Green Energy and Wuxi Suntech have suffered serious losses this year. The stock price has fallen by more than 70%. Suntech's current stock price is only around US$2, and its stock price has reached a maximum of 85. Dollars. What is even more worrying is that in 2008 China's PV companies were still less than 100, and so far it has expanded to more than 500 companies. The current domestic production capacity is estimated to have reached 30gw-40gw, and the global installed capacity of photovoltaics is expected to reach 21gw in 2011, that is, It said that even if China uses photovoltaic cells in the world, China still has 1/3-1/2 of its production capacity to be vented, and factories have to close their doors.
What is 5G CPE?
Definition of 5G CPE
CPE stands for Customer Premise Equipment. The so-called front end refers to the equipment in front of the customer's terminal equipment. When we use Wi-Fi, if the distance is far, or there are more rooms, it is easy to appear signal blind spots, resulting in mobile phones or ipads or computers can not receive Wi-Fi signals. The CPE can relay the Wi-Fi signal twice to extend the coverage of Wi-Fi.
What are the benefits of CPE?
Through the following comparison table, it is not difficult to understand the technical advantages of CPE products:
* Currently, the global 5G FWA service is mainly in the Sub-6GHz band, with only the United States and Italy supporting the millimeter wave band.
* 5G CPE integrates the low cost of Wi-Fi and the large bandwidth of 5G, combining the advantages of the two to form a strong complement to traditional fiber broadband.
The relationship between 5G, FWA and CPE
It can be said that FWA (Fixed Wireless Access) will be the most down-to-earth application of 5G technology. FWA business plays a key role in enabling "connecting the unconnected." FWA is a low-cost, easy-to-deploy flexible broadband solution. Compared with wired access technology, FWA has been an ideal choice for deploying broadband in many countries and regions because it does not need to obtain rights of way, dig trenches and bury cables, and drill holes through walls. The development of 5G technology is further promoting the development of FWA.
FWA services (including 4G and 5G) have reached 100 million users. FWA is no longer a niche service; The FWA industry as a whole has been supported by numerous suppliers. Why is that? In the 5G era, 5G CPE receives 5G signals from operator base stations and then converts them into Wi-Fi signals or wired signals to allow more local devices to get online. For operators, the initial user penetration rate of 5G is low, and the investment is difficult to realize quickly; The CPE business can use the idle network to increase revenue for operators, so major operators vigorously promote the development of 5G CPE.
FWA services can be used for both home (To C) and business (To B), and customers have different requirements for CPE devices when using FWA services in different application environments, resulting in consumer grade 5G CPE and industrial grade 5G CPE (similar to home routers and industrial routers).
In 2020, the global market size of 5G CPE will reach 3 million units, and it is expected that in the next five years, the market size of 5G CPE will maintain a compound growth rate of more than 100%, reaching 120 million units in 2025, with a market value of 60 billion yuan. As an important market for 5G CPE, China's 5G CPE market size will reach 1.5 million units in 2020 and is expected to reach 80 million units in 2025, with a market value of 27 billion yuan.
The difference between 5G CPE and other devices
CPE can support a large number of mobile terminals that access the Internet at the same time, and the device can be directly inserted with a SIM card to receive mobile signals. CPE can be widely used in rural areas, cities, hospitals, units, factories, communities and other wireless network access, can save the cost of laying wired networks.
A Router is a hardware device that connects two or more networks, acts as a gateway between networks, and is the main node device of the Internet. Routers use routes to determine the forwarding of data. If it is a home router, it does not support a SIM card slot, and can only receive signals by connecting to optical fiber or cable and then convert it into WI-FI to provide a certain number (several) of terminal devices to surf the Internet.
Industrial 5G CPE is equivalent to 5G industrial routers, and the technology of the two is not very different. On the one hand, the industrial 5G CPE converts 5G network signals into WiFi signals for transmission, and on the other hand, the data received by the WiFi network is converted into 5G network signals for uploading. In addition, industrial 5G CPE generally supports routing functions.
5G CPE trends
According to a research report, after evaluating the products of some mainstream 5G CPE suppliers, many institutions believe that the development of 5G CPE products will continue in two aspects: one is to support mmWave and Sub-6 GHz at the same time; Second, the design will pay attention to humanized operation and installation. The industry development trend will accelerate the demand for 5G in the medical, education and manufacturing industries due to the epidemic, and 5G FWA will promote global 5G CPE shipments.
