To ask "What is the most feared problem of photovoltaic power generation?" Experienced people must know "the problem of shadow occlusion." 1. Small shadows, big hazards Because the position of the sun changes with the seasons and time, and the surrounding potential obstructions also change over time, anyone with experience in installing photovoltaic power plants understands that shadows are ...
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...
Definition of state of charge (SOC) and depth of discharge (DOD) and their impact on lifespan of lifepo4 battery 1. State of Charge (SOC, State of Charge): In layman's terms, it is the ratio of the power stored in the battery (releasable capacity) to the maximum power that the battery can store. For example, if a battery with a maximum capacity of 100Ah(fully charged) is fully discharged to 5...
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...
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...
