First, what is the solar light solar light is converted from solar panels to electrical energy. During the day, even on cloudy days, this solar generator (solar panel) collects and stores the energy needed. Therefore, the sun produces energy that is used to produce electricity. As a kind of “inexhaustible, inexhaustible†safety and environmental protection new energy, solar energy has received more and more attention.
Solar lamps can be widely used in embellishments such as grasslands, squares, and parks, and belong to the field of lighting technology. The main use of the lampshade to connect the bottom bracket, the battery plate is placed on the battery box is built into the lampshade, the battery box is installed on the bottom bracket, the light emitting diode is mounted on the battery board, and the solar battery board is connected with the rechargeable battery and the control circuit by the wire. The utility model structure is integrated, simple, compact, and reasonable; no external power line is provided, and the utility model is convenient to use and install, and the appearance is beautiful; since the light emitting diode is placed in the bottom bracket, the whole lamp body is illuminated after being illuminated, and the light sense effect is better; All electrical components are built-in and have good practicality. Including serpentine lights, plate lights, solar neon lights, massage lights and many other.
Second, the advantages and disadvantages of solar lamp analysis Solar lighting and city lighting compared to other unique advantages:
First of all, the installation of city lighting fixtures is complicated: In the city lighting project, there are complex operating procedures. The first step is to lay cables. Here, we need to carry out a large number of basic projects such as excavation of cable trenches, laying of dark pipes, pipe threading, and backfilling. Then, after a long time of installation and debugging, if there is a problem with any of the lines, a large area of ​​rework is required. Moreover, the terrain and line requirements are complex, and labor and auxiliary materials are expensive. Solar lighting is easy to install: When solar lighting is installed, there is no need to lay complicated lines. Just make a cement base and then fix it with stainless steel screws.
Secondly, the electricity cost of municipal lighting fixtures is high: there are fixed high electricity rates in the work of city lighting fixtures, and maintenance and replacement of lines and other configurations are required for long-term uninterrupted maintenance. The maintenance costs are increasing year by year. Solar lighting fixtures are free of electricity: solar lighting fixtures are a one-time investment, without any maintenance costs, three years to recover the investment costs, long-term benefit.
Third, there are potential safety hazards for utility lighting: Mains lighting fixtures have caused a number of safety hazards due to construction quality, renovation of landscape projects, aging of materials, abnormal power supply, and conflicts in water and electrical pipelines. There is no safety risk for solar lighting: solar lamps are ultra-low voltage products and are safe and reliable to operate.
Fourth, the application of solar lamps is green and environmental protection. It can add new selling points for the development and promotion of noble ecological communities; it can continuously reduce the cost of property management and reduce the cost of owners’ public apportionment.
In summary, the intrinsic characteristics of solar lighting, such as safety, no hidden dangers, energy-saving and non-consumption, environmental protection, easy installation, and automatic maintenance and maintenance, will directly bring obvious advantages to the sale of real estate and the construction of municipal projects.
Solar lights also have their drawbacks in their road lighting applications:
1. The conversion rate of solar energy into electrical energy depends on the quality and area of ​​the silicon crystal plate. The better the material, the larger the area, the higher the cost. The only way to achieve low cost and good effect is to use low-power, high-brightness light sources. (LED)
2. The selection of energy-storage batteries is also very important. Most manufacturers choose low-temperature, high-temperature, and corrosion-resistant batteries to reduce costs. The results directly lead to unstable supply current, short product life, low energy storage, and low light consumption. bright.
3, the controller can not be ignored, because it indirectly determines the solar energy conversion and storage effects, directly determines the light source life and time accuracy.
Third, the price analysis of solar street lamp Solar street lamp has the following several parts, so its price can do some reference:
The sum of the above parameters is the price of a street lamp. If it is a project, then the corresponding profit point IV. Subsidies for solar energy in all countries in the world 1. Germany's substantial reduction in subsidies for solar power generation The German government announced on January 22, 2011 that it will substantially reduce solar power generation subsidies but it will not completely withdraw subsidies. . The Federal Ministry of the Environment said that it has reached an agreement with the German solar power industry to further reduce electricity subsidies for photovoltaic systems by 15%. Since the end of 2009, this subsidy has been cut by one third. The move is intended to curb the rapid lending of subsidized solar power costs to consumers. The German government estimates that these costs will be as high as €13 billion in the year 2010.
The German Federal Environmental Protection Agency and the German Solar Industry Association (BSW-Solar) announced on the 20th that if the installed capacity of solar cells in today (2011) exceeds 3.5 GW (gigawatts), the original In early 2012, the plan to cut 3-15% of the solar-system power-inforced acquisition (FIT) tariff will be implemented ahead of schedule in July 2011. The estimated solar cell installation will be based on the data for the period from March to May 2011. If the newly installed capacity of solar cells in 2011 does not exceed 3.5 GW, the above subsidy reduction plans will still be implemented as scheduled in early 2012.
The EPA pointed out that if the installation of solar energy systems in 2011 is expected to exceed 7.5GW, the subsidies will be reduced by 15% in July; if the installed capacity exceeds 6.5GW, the reduction will reach 12%. In addition, the reductions in subsidies for installations exceeding 5.5 GW, 4.5 GW, and 3.5 GW were 9%, 6%, and 3%, respectively.
2. U.S. Government's Solar Subsidy Policy The U.S. government has actively promoted the "renewable portfollo standard (RPS)", forcing electric power companies to actively adopt solar cells with relatively stable and mature renewable energy sources. Solarbuzz estimates that the solar cell market will grow to 4.5 to 5.5 GW in 2014, which is 10 times more than in 2009, with an average compound annual growth rate of 30%.
3. Japan's solar energy incentive policy Japan's incentive policy will begin accepting applications in February next year. Although not for a single solar energy industry, but for the use of new energy sources such as wind power generation and biomass power generation, the amount of subsidies provided is very high, at most one-third of the operating costs, and the upper limit of the entire project is one billion days. Yuan, in addition, private companies can receive half of the business subsidy if they are willing to import.
4. UK Incentive Policies The UK Power Purchase System (FIT) encourages small-scale, distributed, and self-generating families to install. Solarbuzz data points out that before the introduction of FIT in April 2010, the installed capacity of solar cells was less than 500, but in May it nearly doubled to nearly 1,000. In August, there were 3,600 applications, and the estimated 2014 British solar energy system The installed capacity can reach 501MW.
5. China's Solar-related Subsidy Policy In March 2009, the Ministry of Finance, the Ministry of Housing, and Urban-Rural Development issued the "Implementation Opinions on Accelerating the Application of Solar Photovoltaic Buildings." The opinion pointed out that the central government will arrange special funds to subsidize the qualified demonstration projects for photovoltaic building applications to partially compensate for the initial investment in photovoltaic applications. At the same time, the Ministry of Finance promulgated the Interim Measures for the Administration of Financial Subsidy Funds for Solar Photovoltaic Buildings, and set the subsidy standards as 20 yuan/Wp (peak watts) in principle.
In July 2009, the Ministry of Finance, the Ministry of Science and Technology, and the National Energy Administration jointly issued the Interim Measures for the Administration of Financial Subsidy Funds for Golden Sun Demonstration Projects, focusing on supporting the development of photovoltaic power station projects. The method pointed out that 50% of grid-connected photovoltaic power generation project systems and 70% of independent power generation system subsidies.
