It is understood that as a developed province, after the introduction of the above-mentioned national industrial plan, Guangdong should formulate detailed implementation rules for supporting related industries. At present, Guangdong has incentives such as tax subsidies for emerging energy-saving industries such as LED, but the support for resource-intensive enterprises seems to be insufficient.
The national plan is about to be introduced. The plan will be based on energy saving, environmental protection, and comprehensive utilization of resources. It will provide policy support for related industries. The areas involved will include energy-efficient energy-saving technologies and equipment, energy-efficient products, energy-saving service industries, and advanced environmental protection technologies and equipment. Environmental protection products and environmental protection services in six areas. This will be the largest industrial policy plan supported by the relevant government departments in the energy conservation and environmental protection industry. The plan will provide policy support for the development of energy-saving and environmental protection industries in industries, finance, and taxation, and propose some directional goals to guide the development of the industry.
In terms of taxation policy, the plan may be based on the “three exemptions, three and five and a half†tax incentives for energy-saving and environmental protection companies, and then collecting energy-saving and environmental-friendly corporate income tax at a rate of 15% according to the standards of high-tech companies that the country needs to support. In addition, the land use tax and real estate tax for energy-saving and environmental protection companies may be reduced accordingly. Related content such as franchise rights, fee pledge loans, energy conservation and environmental protection industry funds, etc. may also be reflected in the plan.
Prior to this, the company’s income from projects such as public sewage treatment, public waste treatment, comprehensive development and utilization of biogas, energy saving and emission reduction technologies, and desalination of seawater, has been granted “three exemptions and three reductions†since the tax year in which the first production and operation income was obtained. Semi-discount offer. However, after the “three exemptions, three reductions and one half†preferential period, the 25% regular corporate income tax rate imposes a relatively large burden on enterprises for energy-saving and environmental protection companies with high one-time investment and long return period. If high-tech enterprises are used in comparison, the income tax rate for energy-saving and environmental protection enterprises can be collected at a tax rate of 15% in the future, which will greatly reduce the tax burden on energy-saving and environmental-protection enterprises, thereby further enhancing the company's development capabilities.
Guangdong rules should increase support. Xiamen University, director of the China Energy Economic Research Center Lin Boqiang said in an interview that during the 11th five-year period, China has extensive support for energy-saving and environmental protection industries, including taxation, franchising and other aspects. This time the country is preparing to introduce energy-saving and environmental protection industry plans, which is to focus on increasing support for related industries. However, from a national perspective, Lin Boqiang believes that the increase in support is not significant.
"The key point is that the developed provinces should provide greater support for these industries." Lin Boqiang believes that developed provinces such as Guangdong have higher environmental requirements and greater pressure for energy conservation and emission reduction. When national industrial plans are introduced, they should be developed. The larger implementation rules guide the development of energy-saving and environmental protection industries from many aspects such as industry, taxation, and finance.
In this regard, the relevant person in charge of the Guangdong Provincial Energy Conservation Association stated that Guangdong has been very supportive of the development of energy-saving and environmental protection industries, but these industries cover a wide range. Before the national plan was issued, Guangdong Province did not have any specific support details.
At present, for emerging energy-saving industries such as LED, Guangdong Province has taxation subsidies and other advantages, and there are also many supporters throughout the province. However, for the comprehensive utilization of resources, it seems that it is not clear enough. Wu Weiguang, chairman of Harbour Group Co., Ltd., which specializes in the recovery of renewable resources, said in an interview with a Southern Metropolis reporter that the group has factories in Guangzhou and Dongguan. It mainly recycles waste paper, scrap iron and waste rubber, and the annual production value can reach 2 to 3 Billion yuan, and joined at all levels of renewable resources associations, "but did not enjoy the tax benefits." He said that due to its commitment to tax subsidies in Jiangxi, the group is preparing to shift its investment focus to Jiangxi and build a renewable resources base.
Industrial concentration will increase It is reported that in terms of corporate support, the national energy conservation and environmental protection industry plan may mention the cultivation of a batch of RMB 5 billion to 100 million yuan worth of environmental protection leading enterprises. Compared with the development of foreign industries, China's environmental protection industry has the problem of small companies and low industrial concentration. The key to making the environmental protection industry bigger and stronger is to expand and strengthen the company and gradually increase the degree of industrial concentration. To this end, the plan may propose directional goals.
Lin Boqiang said that China's environmental protection industry is still at an early stage, such as the garbage disposal industry. There are many people who do it, but they are scattered. The degree of concentration of related industries will increase, which will help improve the level of technology. According to the data, as of 2009, the world’s largest environmental protection company Veolia Group’s operating income was 32 billion euros, and the second largest environmental company Suez Group’s operating income was 12.3 billion euros. At present, most of China's large-scale environmental protection companies have annual operating revenues of 2 billion to 3 billion yuan.
Micro inverter is a small inverter used in solar power generation systems, its main function is to convert the direct current generated by a single Solar Panel into alternating current. Unlike traditional centralized inverters, microinverters are usually equipped with one per solar panel, that is, each solar panel has an independent microinverter.
Main effect:
1. Individual control: The microinverter provides independent conversion control for each solar panel, which means that each solar panel can optimize its power output individually. This maximizes the power generation efficiency of the solar panels since shading or other influences only affect the power generation efficiency of individual panels, not the entire array.
2. Reliability: Since each solar panel is equipped with a micro-inverter, even if one of the inverters fails, the other panels can still work normally, thereby improving the reliability of the entire system.
3. Flexible installation: Micro-inverters are usually small and can be installed near solar panels without being concentrated in one location, so installation is more flexible and convenient.
Differences from other inverters:
1. Individual control: Compared with traditional centralized inverters, microinverters provide independent conversion control for each solar panel, enabling each panel to reach its maximum power output.
2. Fault isolation: The micro-inverter has the function of fault isolation. Even if one of the inverters fails, other panels can continue to work without affecting the operation of the entire system.
3. Installation method: The micro-inverter can be flexibly installed near the solar panel, and does not need to be concentrated in one location, so the installation is more flexible and convenient.
4. Applicable scale: micro-inverters are usually used in small-scale solar power generation systems, while traditional centralized inverters are suitable for larger-scale photovoltaic power plants.
Overall, the main role of microinverters is to individually control and optimize the power generation efficiency of solar panels and improve the reliability of the system. Compared with traditional centralized inverters, it has some advantages in terms of flexibility, fault isolation and applicable scale.
