太阳能光伏发电是怎么回事,我们在这里总结了几个常咨询的问题,为您讲解,如下:
In order to let you know more about solar photovoltaic power generation, we have summarized several frequently asked questions and explained them to you as follows:
1、冬天天冷时会不会电力不足?
1. Will there be a shortage of power in winter when it is cold?
解答:光伏系统的发电量的确受温度的影响,直接影响发电量的因素是辐照强度和日照时长以及太阳能电池组建的工作温度。冬天难免辐照强度会弱,日常时长会短,一般发电量较夏天会少,这是很正常的现象。分布式光伏系统与电网相连,只要电网有电,家庭负载就不会出现电力不足和断电的情况。
Answer: The power generation of the photovoltaic system is indeed affected by temperature. The factors that directly affect the power generation are the radiation intensity, sunshine duration and the working temperature of the solar cell assembly. It is inevitable that the radiation intensity will be weak in winter, the daily duration will be short, and the power generation will generally be less than in summer, which is a normal phenomenon. The distributed photovoltaic system is connected to the power grid. As long as the power grid is available, the household load will not suffer from power shortage and power failure.
2、光伏发电是否有辐射、污染?
2. Is there radiation and pollution in photovoltaic power generation?
解答:目前从运行看,光伏发电是没有辐射和污染的。但是会有电池和噪音问题。电子设备在运行时会有噪音,但在可控范围内。电池类似手机、相机电池等有小剂量的辐射,但不会是大问题。”光伏发电电池板回收是否有辐射主要看其材料。如果是晶硅太阳能电池回收没有太多污染源,同样,非晶硅光伏太阳能产品,主要看选择何种材料。“有些惰性材料要好些,毒性要小些。”
Answer: At present, from the perspective of operation, photovoltaic power generation is free from radiation and pollution. But there will be battery and noise problems. The electronic equipment will have noise during operation, but it is within the controllable range. Batteries like cell phones and camera batteries have a small dose of radiation, but it will not be a big problem. " Whether there is radiation from photovoltaic power generation panel recycling depends on its materials. If the recycling of crystalline silicon solar cells does not have too many pollution sources, similarly, amorphous silicon photovoltaic solar products mainly depend on the choice of materials. "Some inert materials are better and less toxic."
3、分布式光伏发电系统应用范围及安装方式?
3. Application scope and installation mode of distributed photovoltaic power generation system?
解答:分布式光伏发电系统可安装在任何有阳光照射的地方,包括地面、建筑物的顶部、侧立面、阳台等,其中在学校、医院、商场、别墅、居民、厂房、企事业屋顶、车棚、公交站牌顶部应用为广泛;安装方式有混凝土、彩钢板以及瓦片式三个类型。
Answer: The distributed photovoltaic power generation system can be installed in any place with sunlight, including the ground, the top of buildings, side facades, balconies, etc. It is widely used in schools, hospitals, shopping malls, villas, residents, factories, roofs of enterprises and institutions, car sheds, and the top of bus stops; The installation methods include concrete, color steel plate and tile type.
4、安装分布式光伏系统时应如何考虑荷载对光伏方阵和建筑物的影响?
4. How to consider the impact of load on photovoltaic array and buildings when installing distributed photovoltaic system?
解答:从安全和稳定的角度出发,设计时需要考虑荷载、风荷载、雪荷载、温度荷载对光伏方阵和建筑物的影响,保证光伏组件。支架及方阵基础有足够的强度和刚度抵御当地极端气候的侵害。分布式系统安装之前,要对建筑物的荷载能力进行勘测、计算和校核,在保证建筑物满足载荷的前提下,设计出合理的安装施工方案。
Answer: From the perspective of safety and stability, the impact of load, wind load, snow load and temperature load on the PV array and buildings should be considered in the design to ensure the PV modules. The support and array foundation have enough strength and stiffness to resist the local extreme weather. Before the installation of the distributed system, the load capacity of the building shall be surveyed, calculated and checked. On the premise of ensuring that the building meets the load, a reasonable installation construction scheme shall be designed.
5、分布式光伏发电补贴资金通过什么方式发放给业主?
5. How is the subsidy fund for distributed photovoltaic power generation distributed to owners?
解答:光伏发电项目可由电力用户自建,也可采用合同能源管理方式。合同能源管理企业应与电力用户依据关于合同能源管理等规定,签订能源服务协议。用户自建光伏系统的自用光伏电量不做交易,对于项目业主安装在其他电力用户屋面上的自用光伏电量,由项目业主与电力用户按照合同能源管理协议进行结算。对多余光伏上网电量,由电网企业负责计量、统计、光伏系统全部发电量均可得到电量定额补贴。电网企业依据光伏电量的计量数据按照规定的度电补贴标准按照结算周期转拨补贴资金。
Answer: Photovoltaic power generation projects can be built by power users themselves, or energy contract management can be adopted. Energy contract management enterprises shall sign energy service agreements with power users in accordance with national regulations on energy contract management. The self used photovoltaic power of the user's self built photovoltaic system will not be traded. The self used photovoltaic power installed on the roof of other power users by the project owner will be settled by the project owner and the power users in accordance with the energy management contract agreement. For the surplus photovoltaic grid energy, the power grid enterprise is responsible for measuring and statistics, and all the power generated by the photovoltaic system can receive the national electricity quota subsidy. The power grid enterprises shall transfer the national subsidy fund according to the measurement data of photovoltaic power according to the national electricity subsidy standard and the settlement cycle.
