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...
Inverters running in summer may feel hot to the touch due to their high shell temperature. And why does the casing feel hot? The following will do some analysis and answers for these two problems combined with inverter heat dissipation. The components in the inverter have their rated operating temperature. If the heat dissipation performance of the inverter is poor, as the inverter continues to wo...
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....
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, 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...
On the evening of July 11, Deye shares issued an announcement saying that recently, the company found that the micro-inverters produced and sold by the company reported by the media were inconsistent with the certification. The article mainly questioned the micro-inverters sold by the company to Germany because of The lack of relays does not meet the German VDE4105 grid-connected certification con...
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...
