Silan Micro released its 2012 annual report. The company's total operating revenue in 2012 was 1.35 billion yuan, down 12.74% from 2011. The company's operating profit was -55.22 million yuan, a decrease of 142.72% compared with 2011; the company's total profit was 14.45 million yuan. Compared with 2011, the company's net profit was RMB 18.27 million, which was 88.07% lower than that of 2011.
Among them, Silan Mingxin achieved operating income of 155 million yuan in 2012, a decrease of 54.69% from 2011, and a net profit of -29.13 million yuan, a decrease of 152.93% from 2011.
Silan Micro said that the main reason for the decrease in the net profit of Silan Mingxin is: due to the intensified competition in the LED industry, the price of Silan Mingxin LED color screen chips has dropped significantly in 2012, which has greatly squeezed the products. Profit margins. Despite the large operating pressures, Silan Mingxin has made great progress in the construction of epitaxial capacity, the improvement of PSS substrate technology and the improvement of chip quality through continuous investment.
According to the annual report, in December 2012, the production capacity of Silan Mingxin's LED epitaxial wafers has been increased to 60,000 pieces per month, and the production capacity of LED dies has increased to 1.4 billion pieces per month. With the expansion of production capacity and the complete self-sufficiency of epitaxial wafers and PSS substrates, the production cost of Silan Mingxin has been greatly reduced. In 2012, Silan Mingxin has developed LED chips for lighting and achieved mass sales. In 2012, the sales performance of Silan Mingxin Subsidiary-Hangzhou Meikale Optoelectronics Co., Ltd. failed to grow, but the quality of Meikale products remained stable and the performance of the products continued to improve (has reached the level of international manufacturers). The Mikale brand has gradually been recognized by many domestic and foreign brand customers, and future orders will rise as expected.
Looking forward to 2013, the Silan micro-product line planning has basically not changed, and will be planned, managed and operated in six aspects: power supply and power drive product lines, digital audio and video product lines, MCU product lines, mixed signal and RF product lines, Discrete device product line, LED device product line, etc.
Aluminum core Solar Cable is a photovoltaic circuit using aluminum as a conductive material. It is widely used in solar power generation systems to transport the electricity generated by solar panels.
Compared with traditional copper solar cable, aluminum solar cable has some obvious advantages, the most important of which is low cost.
1. Low price: Aluminum is a common metal, and its price is cheaper than that of copper. Therefore, the use of aluminum solar cable can reduce the cost of the system and make the entire photovoltaic power generation project more economical.
2. Lightweight: Aluminum has a lower density and is lighter than copper. The aluminum core optical cable can reduce the weight of the cable and facilitate installation and maintenance.
3. Strong corrosion resistance: Aluminum has good corrosion resistance and can maintain a long service life under harsh environmental conditions. This makes the aluminum solar cable more reliable for outdoor use.
4. Excellent conductivity: although the conductivity of copper is higher than that of aluminum, the aluminum solar cable can make up for the shortcomings of the low conductivity of aluminum to a certain extent by optimizing the design and process and ensure the efficiency and stability of power transmission.
It should be noted that there are also some limitations and precautions for aluminum solar cable. Due to the low conductivity of aluminum, the resistance of the aluminum solar cable will be relatively high, so it is necessary to choose the wire diameter and length reasonably when designing and installing to ensure the efficiency of power transmission. In addition, aluminum is prone to electrochemical reactions when it comes into contact with copper, so corresponding measures need to be taken when connecting aluminum solar cable and other components, such as using special connectors or coating protective layers.
In general, aluminum solar cable with its low cost, corrosion resistance, light and other advantages, has been widely used in solar power generation systems, and brings economic and reliability benefits to photovoltaic power generation projects.
