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 ...
Structural analysis of photovoltaic modules The basic service life requirement of photovoltaic modules is that "after 25 years of outdoor work, it can still maintain 80% of the maximum output power of the initial value, and it is also required that it can effectively resist the impact of external forces. Photovoltaic modules are mainly composed of solar cells, backplanes, photovoltaic glass, packa...
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...
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....
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...
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...
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...
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...
