For the PV power station investors, the power station every more than one degree of electricity will be more than one degree of electricity revenue, because the power station's power generation is directly related to the return on investment cycle, so the investors are most concerned about the power station's power generation. A photovoltaic power station's power generation will be affected by many factors, such as: photovoltaic modules, inverters, cable quality and so on.

In the many elements affecting the power generation of photovoltaic power generation system, shadow shading is a relatively common one, common shading mainly includes utility poles, trees, guardrails, bird droppings, dust, and module front and rear row shading. Therefore, not only in the power plant design to avoid the shadow blocking, but also focus on the later operation and maintenance, regular cleaning components.

The capacity ratio is the ratio of the installed capacity of the PV system to the rated capacity of the inverter. The capacity ratio is the ratio of the installed capacity of the PV system to the rated capacity of the inverter. Currently, overmatching design is often used to improve the comprehensive utilisation rate of the PV system, reduce the system cost of electricity and increase the revenue of the power station. Therefore, a reasonable design of the system capacity ratio is conducive to improving the economy of the PV power generation system.

3. Impact of improper cable selection on power generation

Cables are the nervous system of PV system, connecting PV modules, inverters, convergence boxes, grid-connected cabinets and other equipment in series into a whole. Therefore, reasonable cable selection is crucial for the whole PV system. Cable design selection should choose the right wire diameter, especially for large-scale PV power plants, covering a large area, the line is longer, if the AC cable wire diameter is too thin, it will lead to cable overload, heat, not only affect the power generation, there will be a short-circuit, fire and other potential safety hazards.

 

From Yu Li energy 10 + industry experience, summed up the above points: photovoltaic power plant power generation not only depends on the photovoltaic power plant's own power generation performance, but also with the later operation and maintenance is closely related to the correct operation and maintenance not only to improve power generation, but also to improve the equipment and the service life of the power plant.
