随着光伏的发展，其中工商业光伏发电项目，因为投资，同时还能缓解企业的产能压力而备受企业的青睐，因为光伏发电和负荷用电相对同步，自发自用比例很高，在工商业电价相对较高的情况下，能取得不错的经济效益。下面来讲讲工商业工厂安装光伏注意的几个事项。

With the development of photovoltaic technology, industrial and commercial photovoltaic power generation projects are favored by enterprises because of their high investment income and the ability to relieve the pressure of enterprises' production capacity. Because photovoltaic power generation and load power consumption are relatively synchronous, the proportion of spontaneous self-use is high, and good economic benefits can be achieved under the relatively high industrial and commercial electricity prices. Here are some points for attention when installing PV in industrial and commercial plants.

一、屋顶承受能力

1、 Roof bearing capacity

在安装工商业光伏电站的时候需要注意，要确认屋顶的承载能达到安装光伏电站的要求，要拿到厂房建筑结构图纸，由结构工程师进线屋面增加荷载计算；如果是彩钢瓦屋面，要确认彩钢瓦瓦型，彩钢瓦屋面破损、腐蚀生锈、防水情况；屋面设备情况，是否有风机、气窗、采光带、空调，是否有女儿墙，女儿墙高度，以现场实际测量为准。

When installing industrial and commercial photovoltaic power stations, attention should be paid to the confirmation that the bearing capacity of the roof can meet the requirements of installing photovoltaic power stations, and the structural drawings of the plant building should be obtained, and the structural engineer should enter the roof to add the load calculation; If it is a color steel tile roof, confirm the color steel tile type, the color steel tile roof damage, corrosion, rust and waterproof; The situation of roof equipment, whether there are fans, air windows, lighting belts, air conditioners, whether there are parapets, and the height of parapets, shall be subject to the actual measurement on site.

在北方，要注意冬天下雪对支架承载的影响，如果支架设计载荷末考虑积雪负荷，当遭遇大暴雪时，有造成支架全部或局部坍塌的危险，从而导致太阳能电池组件损坏，进而有可能导致整个光伏发电系统的瘫痪。在沿海地区，要严格参照沿海建筑物的抗风抗震参数进行设计，选择具有较强耐压能力的镀锌支架，光伏系统的阵列布置要充分考虑抗风的御风口。

In the north, we should pay attention to the impact of snow in winter on the bearing capacity of the support. If the design load of the support does not consider the snow load, there is a risk that the support will collapse completely or partially in case of heavy snow, which will lead to the damage of the solar cell module, which may lead to the paralysis of the entire photovoltaic power generation system. In coastal areas, the design shall be carried out in strict accordance with the wind and seismic resistance parameters of coastal buildings, and the galvanized support with strong pressure resistance shall be selected. The array layout of photovoltaic system shall fully consider the wind-resistant wind vent.

当然，随着技术的发展，新型的柔性板也可以实现在低荷载前提下，实现轻薄化的光伏发电。柔性板无边框，无玻璃，可以弯曲，重量只有常规的十分之一，3KG。直接胶粘，对荷载老旧厂房有很好的效果。

Of course, with the development of technology, new flexible panels can also realize lightweight photovoltaic power generation under the premise of low load. The flexible plate has no frame, no glass, and can be bent. Its weight is only one tenth of the conventional one, 3KG. Direct gluing has a good effect on the load of old plants.

二、设备情况

2、 Equipment

除了屋顶承载能力和阴影遮挡之外，工业厂房还是考察厂房内的设备情况，如果厂家内有大型吊车，电焊机，电炉等大功率感性设备，会造成工业厂房的电压不稳定，电流谐波超标，逆变器的并网点如果接在380V的低压侧，逆变器会重复启动。

In addition to the roof bearing capacity and shadow shielding, the industrial plant still inspects the equipment in the plant. If there are large cranes, welding machines, electric furnaces and other high-power inductive equipment in the factory, the voltage of the industrial plant will be unstable, and the current harmonics will exceed the standard. If the connection point of the inverter is connected to the low voltage side of 380V, the inverter will start repeatedly.

光伏发电系统的使用与维护的好坏直接影响着系统的使用寿命，影响着系统的运行成本和发电效率。一般情况下，无需对太阳能电池组件进行表面清洁处理，但对暴露在外的接线接点要进行定期检查、维护。遇有大风、暴雨、冰雹、大雪等情况，应采取措施保护太阳能方阵，以免损坏。更多相关事项就来我们网站//tianjibiotech.com咨询！

The use and maintenance of photovoltaic power generation system directly affects the service life of the system, and affects the operation cost and power generation efficiency of the system. Generally, there is no need to clean the surface of the solar cell module, but the exposed connection points should be regularly inspected and maintained. In case of strong wind, rainstorm, hail, heavy snow, etc., measures shall be taken to protect the solar array to avoid damage.
