太陽能光熱發電是指利用大規模陣列拋物或碟形鏡面收集太陽熱能，通過換熱裝置提供蒸汽，結合傳統汽輪發電機工藝，從而達到發電的目的。那么可以從哪幾方面來分析光伏發電技術的發展？下面工商業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:

技術實用性方面，光伏發電技術發展較為成熟，技術實用性強，但是技術難度也較高，核心技術仍掌握在少數發達的手中。而光熱技術門檻低，盡管在儲熱、冷卻等方面還存在很多問題，但是這些問題并非無法攻克，可以通過參與國際間技術合作、實施鼓勵高新技術研發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.

環境污染方面，光伏多晶硅電池的生產短期內擺脫不了高污染與高能耗。例如，目前生產的多晶硅電池，80%的材料需要從國外進口，而90%的成品則返銷海外。盡管能夠賺取一定的產業利潤，但短時間內依然面臨污染環境的壓力。相比較而言，太陽能光熱發電站的建造和維護對環境的影響小、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，光伏發電的優勢非常明顯且布局較為靈活，借助于未來智能電網的發展，家庭的光伏發電可以合并入網。相比于光伏發電，光熱發電的規模效應則相對明顯，光熱電站的建設規模越大，單位電量的成本越低。因此光熱發電適合建設大規模電站，對土地面積、資金規模等要求較高。

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，光熱發電避免了昂貴的硅晶光電轉換工藝，可大大降低太陽能發電成本。而且，這種形式的太陽能利用具有其他形式的太陽能轉換所無法比擬的優勢，即太陽能所燒熱的水可以儲存在巨大的容器中，白天采集光熱后可直接驅動汽輪機發電，并將余熱存儲于儲熱系統中，夜間光照不足時可以通過儲熱發電以實現供電的持續穩定，特別適合在強光照的荒漠地區進行大規模并網發電。

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.

如果太陽能光熱發電技術的大規模商業化應用取得成功，勢必能為光熱發電技術的推廣和普及帶來重大突破，也將有效地改觀太陽能發電領域光伏發電技術一家獨大的窘迫局面，提升太陽能發電領域的整體競爭力。您有相關的需求就來我們網站http://www.51dwgw.cn咨詢吧！
