The other is solar thermal power generation, solar thermal energy is driven through the heat generator power generation, the basic composition including the collector, energy storage systems, heat engines and generators. Some countries are developing high-power devices, has reached the level of practical application of grid-connected power generation. As the solar thermal power generation technology is complex, commercial applications are only suitable for relatively large capacity, so the development of unpleasant, practical application of small. In this case,
(2) solar photovoltaic power generation: not through the thermal process, directly to the sun's light energy into electricity use, can be divided into photovoltaic power generation, light-induced power generation, photochemical power generation and photobiology. The current application of photovoltaic power generation, will be irradiated on the solar cells on the light, resulting in direct conversion of photovoltaic effect into DC power output, usually by the square of solar cells and racks, batteries, controllers, inverters and other components. Its shortcomings: intermittent. Affected by climatic conditions; low energy density; high initial investment. So far, more than 100 countries have been involved in the development and application of solar photovoltaic cells. In recent years, production has increased rapidly. Production costs began to decline [7]. Currently. Photovoltaic power generation is mainly used for three major areas: to provide power for the non-electric occasions; solar household electronic products. Such as various types of solar chargers, solar lamps, etc .; In this case,
The basic characteristics of solar cells
The volt-ampere characteristics of the solar array are strongly non-linear. The nominal power of the array of solar cells is defined as: S = l000W / m2; solar cell temperature T = 25C; air mass AM = 1.5, the maximum output power of the solar cell array is defined as its rated power. The rated power of the solar cell array is "peak tiles", and "Wp" is used. In this case,
In order for the solar cell module to receive as much of the solar radiation as possible during the year, an optimum inclination angle is selected for the solar cell module. On the best tilt angle of solar cell components, in recent years, appeared in a number of academic journals.
This article from the concept of street lights to start a systematic understanding of the street, because the solar street lights, although a new thing, but still belong to the street a large team. Therefore, through the analysis of the concept, we stand on the theoretical height of the interpretation of the street lights to grasp, and then by understanding the classification of street lamps, development history, structure, so that we all know the street lights, and use it to guide the design of solar street light The In this design task, for the conscious control of the entire design process, master the design direction, with an objective attitude to sum up the program, consider a lot of factors. Mainly from several aspects to sum up: First, the relevant concepts and advantages of solar street lights summary. Second, the development of relevant analysis and design. Third, the initial design of the appearance of solar street lighting style, divided into six design options, and ultimately choose a more appropriate program.
