In recent years, the application of solar power (PV) power generation has become more and more extensive and has developed rapidly. In the construction process of the photovoltaic power station, in addition to the leading equipment, such as photovoltaic modules, inverters, and step-up transformers, the photovoltaic cable materials connected to the photovoltaic power station have a significant impact on the overall ph

The laying and construction of photovoltaic cables is a significant project. To ensure its regular operation and no failures, it is necessary to eliminate the possibility of problems during laying. The premise of removing issues lies in the construction of cables. Next, Let's look at the problems that need to be paid attention to when constructing lines. 1. Eddy's current problem is caused by current

Solar wires need connectors to connect them in the right place. The most popular 4mm solar wire connector is the solar connector. This connector is used on most newer solar panels, and it provides water/dust protection for the cable. Solar connectors are affordable and ideal for use with 4mm cables, including 6mm solar cables. If you're buying a new solar panel, you'll already have the solar connectors att

1. Damage to the cable insulation The characteristics of photovoltaic cables are determined by the unique insulating materials and sheathing materials for cables. After being irradiated by a radiation accelerator, the molecular structure of the cable material will change, thereby providing its performance in all aspects. However, cables need to be routed on the sharp edges of the roof structure during installation a

The solar junction box connects the solar cell array composed of solar cell modules and the solar charge control device. It is a cross-disciplinary comprehensive design that combines electrical design, mechanical design, and material science. The solar cell module junction box is essential in the composition of the solar module. Its primary function is to connect the electricity generated by the solar cell with the

Step 1: Strip the wires The stripping length is 6~7.5mm, and the number of copper wires cut in the stripping process is no more than 5. It is recommended to use professional strippers to ensure stripping quality. Tool recommendation: PV-AZM wire stripper For conductors with a cross-sectional area of 1.5mm2, 2.5mm2, 4mm2, 6mm2, and 10mm2, with inserts (marked with the cross-sectional area), with len

1. Daily maintenance 1. Check that the cables should be neatly arranged without mechanical damage, and the signs should be complete, correct, and precise. 2. Check whether the ceramic sleeve of the cable terminal is damaged, cracked and dirty, and discharged. 3. Check that the connection of the cable terminals is reliable and there is no overheating and looseness. 4. Check the cable terminal for oil leakage,

What is Solar Power and how does it work When at school we learnt that as well as water, we needed the sun to shine down onto Mother Earth to help sustain the life in all its different types and forms. This included the animal and plant life that inhabits it, as well as to grow our crops for food. But we can also use the radiant light energy from the sun to produce heat, light and energy in the form of electricity
