Briefly describe the content of solar lighting

The user's use requirements, such as lighting for several hours a day, require normal lighting in several rainy days. Then according to the above various conditions to design suitable for local products, we according to the actual situation of the local road, to design solar street lights. Generally, the spacing of solar street lights is 30 meters, and the user can determine the number of lights according to the length and width of the section where the solar street lights need to be installed.

1. Introduction to the current situation of solar photovoltaic

Through the conversion device to convert solar radiant energy into electric energy use belongs to solar photovoltaic power generation technology, photoelectric conversion device is usually the use of semiconductor devices photovoltaic effect principle for photoelectric conversion, so it is also known as solar photovoltaic technology. At present, the world energy supply is tight, all countries are competing for non-renewable energy, and vigorously develop the application of renewable energy, solar energy is one of the inexhaustible green energy. Germany, the United States, Japan and other solar energy utilization has reached a very high degree, with solar power generation, lighting, etc., China has been widely popular in solar water heaters, in the solar roof has also done a lot of projects, in recent years, the country's western development plan, so that many herdsmen use solar lighting, boiling water, watching TV, etc. It is known as the "power plant on horseback". The state has formally legislated the application of solar energy, raised the use of solar energy to the legal point of view, launched the construction of new rural areas, the application of solar lighting state support of 30%, has been officially implemented in the Beijing area, in the western solar resources are good places and coastal cities with rapid economic development are vigorously promoting the application of solar lighting.

With the rapid development of China's society and economy, there is a growing contradiction between the actual quantity of electricity and the actual demand of social development. The background that the main leaders of the Party and the state personally serve as the person in charge of the national energy leading group can be seen that China's energy is facing a severe situation and the state attaches unprecedented importance to energy work. State authorities said that by 2010, China's use of renewable energy to provide electricity generation if China's total electricity generation can not reach 10%, the safe operation of our national economy will be seriously threatened! On the other hand, China has abundant solar energy resources, and more than two-thirds of China's land area has annual total sunshine time exceeding SGJ/MZ and annual average sunshine time exceeding 2200 hours, which is a region with good solar energy utilization conditions. It has favorable conditions for developing high-tech solar energy products. If the mainland is vigorously promoting the photovoltaic power generation user system. The construction of a number of megawatt-level photovoltaic power stations with small investment scale, and the promotion of the use of photovoltaic system products, including lighting and heating, will no longer exist the energy shortage problem plaguing China's economic development.

2, the advantages of photovoltaic power generation

Photovoltaic power generation has many advantages, such as: safe and reliable, no noise, no pollution, energy everywhere, available, not subject to regional restrictions. No need to consume fuel, no mechanical rotating parts, low failure rate, easy maintenance, can be unmanned, short station construction period, random size, no need to respect the assumption of transmission lines, can be easily combined with the building. These advantages are not available to power generation and other power generation methods. The rapid development of China's society and economy provides better development opportunities and space for the photovoltaic market, and it can be hoped that driven by the market and ecological environment, China's photovoltaic industry will certainly have a great development. The use of solar photovoltaic technology to produce and manufacture new solar lighting is an important work for the center to promote the application of photovoltaic system technology in civil high-tech aspects in the recent period, and it is also an important measure to implement the strategic guiding ideology of the Party and the country to build a conservation-oriented society. A few days ago, China's electricity for lighting has exceeded 12% of the total electricity consumption in the country, and 50 million new street lights are added every year, if 1% of them use solar street lights, it will save 700 million degrees of electricity for the country, which is equivalent to giving the country a 100,000 KW power plant without any consumption without any pollution every year. At the same time, the output value of new high-tech products is 5 billion yuan, the new profits and taxes are 15 billion yuan, the related industries are driven by tens of billions of yuan, and the related jobs are nearly 10,000.

Technical analysis

Solar lighting fixtures, including solar street lights, solar garden lights, solar lawn lights, solar corridor lights, etc., are suitable for all places that need lighting.
The basic principle: The solar panel absorbs the radiation energy in natural sunlight, and converts the electrical energy that can be stored or directly supplied to the luminous body through a high-tech system control device for direct lighting, or lighting when needed.

Solar energy is powered by low-voltage DC, so it has the characteristics of safety and reliability, no noise, pollution-free energy available everywhere, no regional restrictions, no fuel consumption, no mechanical rotating parts, low failure rate, easy maintenance, etc. In use, each solar lamp has an independent power supply, which can be placed anywhere, without power design, without power capacity, without artificial power control, without digging trenches and burying pipes, without laying cables and wires, convenient installation, such as road transformation, location movement is more convenient and fast.

Advantages of rural solar street lights

With the promotion of new rural construction, rural road lighting project is also the focus of each new rural construction, but accompanied by a variety of complex rural phenomena, there are many difficulties in rural lighting project, such as:

1, road lighting project investment problem;
2, the installation and construction process is complex, to move the earth, dig the ground, occupy the farmer's place, it is easy to cause the contradiction between the project and the villagers. Not easy to construct.
3, electricity expenses can not be solved. Resulting in the completion of the rear light is almost not bright, can not be used in the actual lighting project.
4, the late maintenance workload is large, the cost is high. Replace parts, original components, etc. Large energy consumption, not energy saving and pollution ring mirror.
Solar street lights, which play a "star" like role in the construction of new rural areas, advantages:
1, energy saving, environmental protection, is the country vigorously improve the green lighting.
2, investment funds are easier to solve, because it is energy saving and environmental protection products, the state will give this project in various places, there are special funds.
3, less investment, comprehensive economic benefits than conventional street lamp investment is basically the same.
4, the construction is simple, no need to open ditches, the previous period is short.
5, no electricity costs, because it absorbs solar energy to generate light, so no electricity costs. Always free power supply.
6, the maintenance is small, almost maintenance-free, because the LED light source has a service life of more than 10 years.
7, beautify the rural ring mirror, more than the traditional street light can attract the eye, forming a beautiful landscape.
8. The concept of energy conservation and environmental protection has penetrated into the countryside and guided the rural people's awareness of energy conservation.

In summary, solar LED lamps have obvious superior performance, especially the energy saving effect is obvious, not only has direct economic savings but also has environmental protection and energy saving effect, reducing greenhouse gas emissions. And solar energy is a safe voltage to avoid many safety hazards. In the later stage, it not only saves energy, but also reduces maintenance workload.
