太阳能光热发电是指利用大规模阵列抛物或碟形镜面收集太阳热能，通过换热装置提供蒸汽，结合传统汽轮发电机工艺，从而达到发电的目的。那么可以从哪几方面来分析光伏发电技术的发展？下面工商业屋顶光伏厂家为您介绍：

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:

技术实用性方面，光伏发电技术发展较为成熟，技术实用性强，但是技术难度也较高，核心技术仍掌握在少数发达的手中。而光热技术门槛低，尽管在储热、冷却等方面还存在很多问题，但是这些问题并非无法攻克，可以通过参与国际间技术合作、实施鼓励高新技术研发政策等方式加以解决。

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.

环境污染方面，光伏多晶硅电池的生产短期内摆脱不了高污染与高能耗。例如，目前生产的多晶硅电池，80%的材料需要从国外进口，而90%的成品则返销海外。尽管能够赚取一定的产业利润，但短时间内依然面临污染环境的压力。相比较而言，太阳能光热发电站的建造和维护对环境的影响小、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，光伏发电的优势非常明显且布局较为灵活，借助于未来智能电网的发展，家庭的光伏发电可以合并入网。相比于光伏发电，光热发电的规模效应则相对明显，光热电站的建设规模越大，单位电量的成本越低。因此光热发电适合建设大规模电站，对土地面积、资金规模等要求较高。

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，光热发电避免了昂贵的硅晶光电转换工艺，可大大降低太阳能发电成本。而且，这种形式的太阳能利用具有其他形式的太阳能转换所无法比拟的优势，即太阳能所烧热的水可以储存在巨大的容器中，白天采集光热后可直接驱动汽轮机发电，并将余热存储于储热系统中，夜间光照不足时可以通过储热发电以实现供电的持续稳定，特别适合在强光照的荒漠地区进行大规模并网发电。

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.

如果太阳能光热发电技术的大规模商业化应用取得成功，势必能为光热发电技术的推广和普及带来重大突破，也将有效地改观太阳能发电领域光伏发电技术一家独大的窘迫局面，提升太阳能发电领域的整体竞争力。您有相关的需求就来我们网站http://www.zdnygf.com咨询吧！
