When designing the inclination of the photovoltaic array, there is a big difference between the grid-connected power station and the off-grid power station, because the goals pursued by the grid-connected power station and the off-grid power station are different when generating electricity. The goal of grid-connected power stations is to maximize the annual power generation, that is, the design o...
In the photovoltaic power station system, the grounding design is a crucial part of the electrical design, which is related to the safety of the power station equipment and personnel. Good grounding design can ensure that the power station is in a safe operating environment for a long time, reduce the frequency of faults, and improve the overall operating efficiency of the power station. Therefore...
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...
The power generation of photovoltaic power plants is determined by many factors, among which the key factors are irradiance and ambient temperature. Hot summer is often accompanied by high temperature, not high irradiance. The temperature characteristics of solar modules are negative temperature coefficients, and the power generation performance of modules will decrease as the temperature increase...
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...
Loads are classified into resistive loads, inductive loads, and capacitive loads according to their impedance properties. Resistive load: A load with no phase difference between current and voltage is a resistive load, such as rice cookers, light bulbs, electric stoves, electric soldering irons, etc. Inductive load: The load when the current lags the voltage by a phase difference is an inductive l...
The German government continues to address the energy crisis by implementing tax relief to support small photovoltaics. This time, the tax relief is aimed at supporting PV systems under 30kW. The new rules plan to start in early 2023, and any photovoltaic system operating on a single-family residential or commercial property with an output of up to 30kW will no longer be required to pay income tax...
Energy storage converter, also known as bidirectional energy storage inverter, English name PCS (Power Conversion System), is used in AC-coupled energy storage systems such as grid-connected energy storage and micro-grid energy storage, connecting battery packs and power grids (or load), it is a device that realizes bidirectional conversion of electric energy. It can not only invert the DC power o...
1. In order to prevent the photovoltaic modules from being hit by heavy objects, can a wire protection net be added to the photovoltaic array? Answer: It is not recommended to install wire protection nets. Because the addition of iron wire protection net to the photovoltaic array may cause partial shadows on the solar panels and form a hot spot effect, which will affect the power generation effici...
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...
