太陽(yáng)能光熱發(fā)電是指利用大規(guī)模陣列拋物或碟形鏡面收集太陽(yáng)熱能，通過(guò)換熱裝置提供蒸汽，結(jié)合傳統(tǒng)汽輪發(fā)電機(jī)工藝，從而達(dá)到發(fā)電的目的。那么可以從哪幾方面來(lái)分析光伏發(fā)電技術(shù)的發(fā)展？下面工商業(yè)屋頂光伏廠家為您介紹：

Solar photothermal power generation refers to the use of large-scale array parabolic or dish-shaped mirrors to collect solar energy, provide steam through heat exchange devices, and combine with traditional steam turbine generator technology to achieve the purpose of power generation. So what aspects can we analyze the development of photovoltaic power generation technology? The following industrial and commercial rooftop photovoltaic manufacturers will introduce to you:

技術(shù)實(shí)用性方面，光伏發(fā)電技術(shù)發(fā)展較為成熟，技術(shù)實(shí)用性強(qiáng)，但是技術(shù)難度也較高，核心技術(shù)仍掌握在少數(shù)發(fā)達(dá)的手中。而光熱技術(shù)門(mén)檻低，盡管在儲(chǔ)熱、冷卻等方面還存在很多問(wèn)題，但是這些問(wèn)題并非無(wú)法攻克，可以通過(guò)參與國(guó)際間技術(shù)合作、實(shí)施鼓勵(lì)高新技術(shù)研發(fā)政策等方式加以解決。

In terms of technical practicability, the photovoltaic power generation technology is relatively mature and practical, but the technical difficulty is also high. The core technology is still in the hands of a few developed countries. The threshold of photo-thermal technology is low. Although there are many problems in heat storage and cooling, these problems are not insurmountable and can be solved by participating in international technical cooperation and implementing policies to encourage high-tech research and development.

環(huán)境污染方面，光伏多晶硅電池的生產(chǎn)短期內(nèi)擺脫不了高污染與高能耗。例如，目前生產(chǎn)的多晶硅電池，80%的材料需要從國(guó)外進(jìn)口，而90%的成品則返銷海外。盡管能夠賺取一定的產(chǎn)業(yè)利潤(rùn)，但短時(shí)間內(nèi)依然面臨污染環(huán)境的壓力。相比較而言，太陽(yáng)能光熱發(fā)電站的建造和維護(hù)對(duì)環(huán)境的影響小、污染少。

In terms of environmental pollution, the production of photovoltaic polysilicon cells cannot get rid of high pollution and high energy consumption in a short time. For example, 80% of the polysilicon batteries produced in China currently need to be imported from abroad, while 90% of the finished products are sold back overseas. Although it can earn certain industrial profits, it still faces the pressure of polluting the environment in a short time. In comparison, the construction and maintenance of solar thermal power stations have little impact on the environment and less pollution.

布局方面，光伏發(fā)電的優(yōu)勢(shì)非常明顯且布局較為靈活，借助于未來(lái)智能電網(wǎng)的發(fā)展，家庭的光伏發(fā)電可以合并入網(wǎng)。相比于光伏發(fā)電，光熱發(fā)電的規(guī)模效應(yīng)則相對(duì)明顯，光熱電站的建設(shè)規(guī)模越大，單位電量的成本越低。因此光熱發(fā)電適合建設(shè)大規(guī)模電站，對(duì)土地面積、資金規(guī)模等要求較高。

In terms of layout, the advantages of photovoltaic power generation are very obvious and the layout is relatively flexible. With the development of smart grid in the future, the photovoltaic power generation of households can be integrated into the grid. Compared with photovoltaic power generation, the scale effect of photothermal power generation is relatively obvious. The larger the construction scale of photothermal power station, the lower the cost of unit electricity. Therefore, photothermal power generation is suitable for the construction of large-scale power stations, with high requirements on land area and capital scale.

成本方面，光熱發(fā)電避免了昂貴的硅晶光電轉(zhuǎn)換工藝，可大大降低太陽(yáng)能發(fā)電成本。而且，這種形式的太陽(yáng)能利用具有其他形式的太陽(yáng)能轉(zhuǎn)換所無(wú)法比擬的優(yōu)勢(shì)，即太陽(yáng)能所燒熱的水可以儲(chǔ)存在巨大的容器中，白天采集光熱后可直接驅(qū)動(dòng)汽輪機(jī)發(fā)電，并將余熱存儲(chǔ)于儲(chǔ)熱系統(tǒng)中，夜間光照不足時(shí)可以通過(guò)儲(chǔ)熱發(fā)電以實(shí)現(xiàn)供電的持續(xù)穩(wěn)定，特別適合在強(qiáng)光照的荒漠地區(qū)進(jìn)行大規(guī)模并網(wǎng)發(fā)電。

In terms of cost, photothermal power generation avoids the expensive silicon crystal photoelectric conversion process, which can greatly reduce the cost of solar power generation. In addition, this form of solar energy utilization has the advantages that other forms of solar energy conversion can not match, that is, the water heated by solar energy can be stored in a huge container, and the solar energy can be collected in the daytime to directly drive the steam turbine to generate electricity, and the waste heat can be stored in the heat storage system. When the light is insufficient at night, the heat storage can be used to generate electricity to achieve the continuous stability of power supply, It is especially suitable for large-scale grid-connected power generation in desert areas with strong sunlight.

如果太陽(yáng)能光熱發(fā)電技術(shù)的大規(guī)模商業(yè)化應(yīng)用取得成功，勢(shì)必能為光熱發(fā)電技術(shù)的推廣和普及帶來(lái)重大突破，也將有效地改觀太陽(yáng)能發(fā)電領(lǐng)域光伏發(fā)電技術(shù)一家獨(dú)大的窘迫局面，提升太陽(yáng)能發(fā)電領(lǐng)域的整體競(jìng)爭(zhēng)力。您有相關(guān)的需求就來(lái)我們網(wǎng)站http://51lib.com.cn咨詢吧！
