On May 13th, after five years of turning, the mainland lighting leading company NVC Lighting Holdings Co., Ltd. (hereinafter referred to as "NVC Lighting") will land in the Hong Kong Stock Exchange in late this month. NVC Lighting's prospectus shows that it plans to issue 727 million shares, with an offer price range of 2.03 to 2.9 yuan per share, and plans to raise 1.446 billion Hong Kong dollars. “NVC has been in the industry for 10 years. In the next 10 years, NVC will be a world brand.†NVC’s founder and president Wu Changjiang’s passion at the annual meeting of entrepreneurs held at the end of last year Said. However, when Wu Changjiang founded NVC lighting in 1 million yuan in 1998, he may not have thought that he would become the boss of the mainland lighting industry in only 10 years. "In the first year, I set my own goal of 30 million yuan. No one believed that the result was 27 million yuan in the first year. More than 60 million yuan in the second year. In 2004, NVC Lighting achieved 600 million yuan in revenue. In 2004, Wu Changjiang, who loved to "shoot the gun", once again said that "In the next five years, NVC lighting will have to be 5 billion yuan." Although Wu Changjiang was bombarded by the industry because of such a speech, the data of the prospectus shows that Wu Changjiang is approaching this goal at the speed of “dark horseâ€. In 2007, NVC Lighting's revenue was 130 million US dollars, net profit was 12.9 million US dollars; 2008 revenue was 256 million US dollars, up 96.9% year-on-year, net profit was 18.1 million US dollars, up 40% year-on-year; in 2009 due to the financial turmoil, NVC Lighting has suspended rapid growth, with revenues of $306 million last year, an increase of 19.53% year-on-year, and a net profit of $14.7 million. However, the comprehensive gross profit margin of its products is in a reverse trend with the traditional lighting industry. In 2007, the comprehensive gross profit margin of NVC Lighting was 23.75%, which rose to 24.53% in 2008 and rose to 27.48% in 2009. The continued increase in product gross profit margin was mainly due to the promotion of national energy conservation policies and the achievements of NVC in energy-saving lighting products in recent years. According to the latest report of China Lighting Association, NVC Lighting ranked second in the mainland lighting market last year, second only to Philips, ranking first for domestic lighting companies. At the same time, NVC Lighting is also the largest manufacturer of energy-saving lamps in the Mainland. According to the data of the prospectus, the sales of energy-saving lighting products accounted for the proportion of total revenue of NVC, from 37.5% in 2007 to 60.1% in 2009, with a compound annual growth rate of 94.1%. On May 7, the China International Economic and Technical Exchange Center of the Ministry of Commerce said that the phase-out of incandescent lamps and the accelerated promotion of energy-saving lamps in China, initiated by the National Development and Reform Commission, the United Nations Development Program and the Global Environment Facility, have been implemented. The total project budget is 1400. Ten thousand dollars, the implementation cycle is three years. According to Freedonia data, the share of China's energy-saving lighting will gradually increase from 35.9% in 2009 to 50.8% in 2014. "In addition to LED lighting, the market structure of other energy-saving lighting products will remain the same, and the market share of each company is hard to exceed 1%." Zhang Xiaofei, CEO of Gaogong LED, pointed out that there are currently more than 10,000 lighting companies in the Mainland, including The top three sales of NVC Lighting and Philips account for only 2.5% of the total sales of lighting products in the Mainland. Now everyone has ordinary energy-saving lighting products, it is difficult to separate high and low in the market. The future competition focus is on LED. Lighting. Perhaps based on this, NVC Lighting also plans to use 10% of the proceeds raised this time to develop LED lighting products. However, NVC lighting LED lighting may still be a long way, because in 2009 LED products accounted for only 0.8% of total revenue. The main function of the Home Energy Storage System is to store the electricity generated by the solar panels in the home photovoltaic power generation system, so as to continue to supply electricity at night, cloudy days, or when the electricity demand exceeds the supply of the solar panels. It is an energy storage solution for improving the self-sufficiency and energy efficiency of home photovoltaic power generation systems. residential energy storage system, solar lithium battery storage, solar panel and battery system for home, solar battery storage for house, household solar battery storage Ningbo Autrends International Trade Co., Ltd. , https://www.china-energystorage.com

Main effect:
Energy Storage: The Home Energy Storage System uses batteries to store excess electricity generated by the home's photovoltaic power generation system. When solar panels generate more power than the household needs, the excess power is stored in the battery to continue supplying power when needed.
Power supply backup: At night, on cloudy days or when the power generated by solar panels is insufficient, the Home Energy Storage System can use the stored power to continue to supply power to ensure the continuity and stability of household power consumption.
Energy balance: The Home Energy Storage System helps to balance the energy difference between the electricity generated by the home photovoltaic system and the electricity demanded, thereby optimizing energy management and maximizing self-sufficiency.
Differences from other energy storage systems:
Power source: The power source of the Home Energy Storage System is the Solar Panel of the home photovoltaic power generation system, which directly generates electricity by converting sunlight. While other energy storage systems may come from other renewable energy sources, such as wind energy, hydro energy, or non-renewable energy sources, such as grid electricity.
Renewable: The Home Energy Storage System uses solar energy as a power source and is a renewable energy system. Other energy storage systems may utilize different types of energy sources, with varying degrees of renewability.
Application Scenario: Home Energy Storage System is mainly used in home photovoltaic power generation systems, especially in conjunction with solar panels. Other energy storage systems can be used in different energy generation systems, selected according to specific energy sources and application requirements.
Overall, the main function of the Home Energy Storage System is to store the electricity generated by the solar panels for continued supply of electricity at night, on cloudy days, or when the home's electricity demand exceeds the supply of the solar panels. Compared with other energy storage systems, it uses solar energy as a power source, is a renewable energy system, and is mainly used in household photovoltaic power generation systems to improve energy utilization efficiency and self-sufficiency.
