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...
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...
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...
