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 ...
The power factor of the photovoltaic grid-connected inverter is a point that has to be mentioned in the technical parameters. In an AC circuit, the cosine of the phase difference (Φ) between the voltage and the current is called the power factor, which is represented by the symbol cosΦ. In terms of value, the power The factor is the ratio of active power to apparent power, that is, cosΦ=P/S. Gener...
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...
A 7.7-magnitude earthquake hit southeastern Turkey near the Syrian border in the early morning of February 6, local time. The epicenter was located in Gaziantep Province, Turkey. Buildings collapsed on a large scale and tens of thousands of people were killed or injured. As of press time, there are still a series of aftershocks in the local area, and the scope of the earthquake's impact has expand...
In recent years, with the continuous reduction of the cost of photovoltaic power generation, photovoltaic power generation has gradually become the main energy source in the new power system. Module products are the core power generation equipment of photovoltaic power stations, and their safety and reliability will directly affect the power station long-term stable operation. Ensuring the quality...
Recently, the power shortage in South Africa has intensified. In order to deal with the energy crisis, the South African government announced that it will encourage private enterprises to increase investment and promote the construction of renewable energy power generation projects while increasing electricity imports. It is understood that in the past few years, South Africa has experienced power...
Recently, it was reported that the Irish government has announced that it will cancel the VAT rate on the supply and installation of solar panels from May 1. Irish Environment Minister Eamonn Ryan has announced that VAT on the supply and installation of solar power system for homes and public buildings will be abolished. The 23% VAT rate will be reduced to 0%, which is expected to save households ...
Recently, the International Energy Agency (IEA) released a new market report on the outlook of the renewable energy market in 2023 and 2024. Globally, new renewable energy capacity will soar from 107GW to more than 440GW by 2023, the largest increase ever, the report said. In 2023, solar energy will still be the main source of global renewable energy capacity expansion, accounting for 286GW, of wh...
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...
Solar air conditioning system is any air conditioning powered by the sun's energy. Solar air conditioners have no emissions and supply their own energy, so customers can lessen their carbon footprint and reduce their energy costs at the same time. Types of Solar Air Conditioning The simplest form of solar air conditioning is a small solar panel that generates enough electricity to run a fan—for ex...
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...
