The power generation of a photovoltaic power station not only depends on the power generation performance of the photovoltaic power station itself, but also is closely related to the later operation and maintenance. Correct operation and maintenance can not only increase the power generation, but also greatly improve the service life of the equipment and power station. Let's discuss the main facto...
With the gradual tightening of global energy supply and increasingly serious environmental pollution, independent and environment-friendly energy supply is becoming more and more important, and more and more households around the world choose to embrace this green energy transition with green electricity at home. However, in the face of the numerous and chaotic household energy storage products on...
First of all, the basis of the working principle of solar cells is the photovoltaic effect of the semiconductor PN junction. The so-called photovoltaic effect is an effect in which electromotive force and current are generated when the object is illuminated, the state of charge distribution in the object changes. When sunlight or other light hits the PN junction of the semiconductor, a voltage app...
The large number of solar panels installed in the early 2000s is approaching the end of its life cycle, which poses a serious problem for the solar industry, and current solar panel disposal methods fall far short of environmental requirements. In theory, solar energy is more promising than ever. Solar cells are getting easier and cheaper to produce. But solar PVs have some less-talked-about quest...
The warranty of a solar system involves solar panels, inverters, installations and various other components. Owners always want to be effectively guaranteed throughout the life cycle of the solar system, and they know that it is important to choose the right solar panels and inverters. , it is also important to know that these components are properly installed. But when it comes to warranty, there...
There are various currents inside the cell, such as dark current, reverse current, leakage current, etc. Various currents have a greater or lesser impact on the power of solar panels. Distinguishing the characteristics of various currents can identify the cause of abnormal solar panel power and help solve the problem completely. dark current Dark current (DarkCurrent), also known as unilluminated ...
At present, there are many models of inverters on the market. In order to simplify management and explore the advantages of centralized procurement, many EPC manufacturers often use limited inverter models to do as many field designs as possible, which will inevitably involve the reduction of inverters. Content usage issues. A small reduction in capacity is not a big problem; but a large reduction...
Photovoltaic inverters are composed of circuit boards, fuses, power switch tubes, inductors, relays, capacitors, displays, fans, radiators, structural parts and other components. The service life of each component is different. The service life of the inverter can be explained by the "barrel theory". The maximum capacity of the barrel is determined by the shortest board, and the service life of th...
