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...
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 ...
Reasons for low insulation resistance: When the solar panels or DC cables and joints are damaged or the insulation layer is aging, the problem of low insulation resistance is easy to occur. When the DC cable passes through the bridge, since the edge of the metal bridge may have barbs, the outer insulation of the cable may be damaged during the threading process, resulting in leakage to the ground....
The South Korean Ministry of Industry, Trade and Energy (MOTIE) approved a solar panel recycling program at a ministerial meeting held by Prime Minister Han Duk-soo a few days ago. It is reported that the new regulations establish a standardized collection system for each major region of the country to ensure that the recycling/reuse rate of waste solar panels exceeds 80%. At the same time, the pl...
With the popularization and application of industrial and commercial photovoltaics, more and more industrial enterprises are using their factory roofs to build photovoltaic power generation system. There is usually no objection to installing photovoltaics on the south slope, but how to deal with the installation of photovoltaics on the north slope of the color steel roof. Whether to continue to us...
The ability of a solar power system to meet the electricity demand of monitoring devices depends on several factors, including the power requirements of the devices and the capacity of the solar system. When determining if a solar system can meet the electricity needs of monitoring devices, consider the following: Power Consumption of Monitoring Devices: Review the power specifications of the moni...
Advantages: (1) Environmental protection: Rooftop photovoltaics panel system can reduce carbon dioxide and greenhouse gas emissions, improve local air quality, and protect the ecological environment. (2) Economical: Rooftop photovoltaics can reduce energy costs and reduce dependence on traditional energy. (3) Long life: The life of photovoltaic panels is up to 30 years or more, reducing repl...
