In order to fully implement the requirements of the 19th National Congress of the Communist Party of China regarding the expansion of the clean energy industry and promote the high-quality development of the photovoltaic sector, the National Development and Reform Commission, the Ministry of Finance, and the National Energy Administration, based on the actual development of the industry, have organized relevant parties to conduct in-depth studies on development policies such as optimizing the scale management of the photovoltaic industry, the electricity price mechanism, and the market-oriented institutional mechanisms since the end of 2017. They have also initiated the formulation of policies and the drafting of documents. During the policy research and formulation process, they drew on the experiences of countries such as Germany, Spain, and the Czech Republic, solicited opinions through various means (such as consultation meetings in February and press conferences in April), provided publicity and guidance, and specially held meetings to listen to the opinions of local development commissions (energy bureaus) and relevant power grid enterprises and made policy explanations. After multiple revisions and thorough deliberations, the "Notice" was officially issued on May 31.

       Photovoltaic power generation is a green and clean energy source, which aligns with the direction of energy transformation and plays a significant role in the energy revolution. Cultivating and expanding the clean energy industry, and supporting the development of clean energy such as photovoltaic power generation are important contents of the energy production revolution and consumption revolution. The National Development and Reform Commission and the National Energy Administration will continue to support the healthy and sustainable development of the photovoltaic industry. Promoting the continuous, healthy and orderly development and high-quality development of the photovoltaic industry is the common responsibility and goal of the industry. We will continue to work with industry-related entities to strengthen research on relevant policy measures.

       The vigorous development of new energy is bound to bring new development opportunities to traditional industries. For the security industry, especially the wireless transmission industry, it has also brought considerable impetus. As is well known, in long-distance wireless transmission applications, especially in some projects such as forest fire prevention in the wild and ecological monitoring in grassland pastoral areas, the power supply for equipment has been a major problem. The popularization of new energy has brought great convenience to these applications.

       The wind-solar complementary monitoring system (pure solar power monitoring power supply system) can be widely applied in forest fire monitoring systems. This system has no air pollution, no noise, and no waste generation. It is a natural and clean energy source. Currently, wind power generation and solar power generation are developing very rapidly worldwide.

       The wind-solar hybrid power generation system mainly consists of a wind turbine, solar panels, a controller, an inverter, a battery bank, cables, supports and auxiliary components to form a power generation system. At night and on cloudy days when there is no sunlight, power is generated by wind energy; on sunny days, power is generated by solar energy. When there is both wind and sunlight, both functions work simultaneously, achieving a 24-hour power generation function. This system is more economical, scientific and practical than using only wind turbines or solar energy alone. The system composition is as follows:

       If traditional camera monitoring methods are used to conduct extensive monitoring in highway projects, forest fire prevention monitoring, pasture pest and disease prevention, border guard posts, etc., large-scale power transmission networks and optical fiber transmission networks need to be constructed. This not only involves high construction difficulty and high construction costs, but also has high maintenance costs and is not operable. However, the photovoltaic power complementary monitoring power supply system or pure solar power monitoring power supply system can be configured with reasonable system capacity according to the user's electricity load conditions and resource conditions, which can not only ensure the reliability of system power supply, but also reduce the cost of the power generation system. No matter what kind of environment or power supply requirements there are, the most optimal system design can be made to meet the user's requirements. With the development of wireless communication technology, wireless transmission of images has become a very easy thing. By using the photovoltaic power complementary power supply system as a supporting solution, it is possible to realize the use of wireless equipment at the remote video monitoring points to transmit images to the monitoring center in the wild. Our company can configure a wind power integrated power supply system according to the user's on-site needs. Details can be viewed in the product center or consulted with our company's sales staff.
