1、太阳能利用类型及原理分析探讨（Analysis and Discussion on types and principles of solar energy utilization）The solar energy utilization type and the principle analysis discussion.Txt, my merit is: I am very handsome, but my shortcoming is: my handsome is not obvious. What is happiness? Happiness is a cat fish, dog

3、 solar energy: 1. Solar energy application; narrow range solar energy is limited to solar radiation heat and light, photoelectric and photochemicalThe direct conversion of solar energy is both primary and renewable. It is rich in resources, free to use, and without transportation, without any pollut

At present, solar power and solar energy are becoming more and more popular.Two,Three,Zhuhai solar water heating projectSolar energy utilizationTwo. Sol
5、ar energy classificationSolar photovoltaicThe photovoltaic panel module is a power generation device that produces direct current direct current when exposed to sunlight. It consists of almost all DC solid solid photovoltaic cells made of semiconducting material (such as silicon). Because there is n
6、o moving part, it can be operated for a long time without any loss. Simple photovoltaic cells provide energy for watches and computers, and complex photovoltaic systems provide lighting for homes and power grids. Photovoltaic panels can be made into different shapes, and components can be connected
7、to generate more power. Photovoltaic panels have been used on roofs and buildings in recent years and are even used as part of windows, skylights or screening devices, which are often referred to as photovoltaic systems attached to buildings. Solar thermal energy, the modern solar thermal technology
8、, combines sunlight and uses its energy to produce hot water, steam, and electricity. In addition to the use of appropriate technology to collect solar energy, the building can also make use of the suns light and heat energy is added in the design of appropriate equipment, such as large windows or u
9、se of the South can absorb and slowly release the sun heat the building materials.Three, advantages and disadvantages analysisAdvantages (1) general: the sun shines on the earth, without geographical restrictions, whether land or sea, whether mountain or island, everywhere, can be directly developed
10、 and utilized, and without exploitation and transportation. (2) harmless: the development and utilization of solar energy will not pollute the environment, it is one of the most clean energy, and in the increasingly serious environmental pollution today, this is extremely valuable. (3) huge: the ann
11、ual solar radiation reaching the earths surface is equivalent to about 130 trillion tons of coal. The total amount of solar radiation is the largest energy source that can be developed in the world today. (4) for a long time: according to the current estimation rate of nuclear energy produced the su
12、n, the amount of hydrogen storage is sufficient to maintain billions of years, and the life of the earth is about billions of years, in this sense, we can say the suns energy is inexhaustible. shortcoming(1) dispersion: Although the total amount of solar radiation reaching the earths surface is larg
13、e, the current density is very low. On average, near the Tropic of cancer, the weather is fine in the summer, the maximum irradiance of solar radiation at noon, in the direction perpendicular to the sun area of 1 square meters of the solar energy received on average is about 1000W; if the year avera
14、ge day and night, only about 200W. In winter, it is only about half, and the cloudy day is only about 1 / 5, so the energy density is very low. Therefore, in the use of solar energy, in order to get a certain conversion power, often requires a large area of collection and conversion equipment, highe
15、r cost. (2) stability: as a result of the day and night, season, geographic latitude and altitude and other natural conditions and sunny, cloudy, rain clouds and other random factors, so, at a certain ground-based solar irradiance is interrupted, it is also extremely unstable, increasing the difficu
16、lty of large-scale application too Yang energy. In order to make solar energy as a continuous, stable energy, and ultimately be able to compete with conventional energy sources of alternative energy sources, it is necessary to solve the storage problem, namely the sunny day the sun radiant energy stored up as far as possible, and for the night or rainy days, but the current utilization of solar energy storage is relatively wea
