How to maintain solar panels

21-12-2020

It is well known that dirt, dust, and debris on the surface of solar panels will affect the efficiency of power generation. I am worried that the power generation efficiency will be far less efficient after a few years than it was at the beginning, so how should we maintain it?


  We all know that solar panels are usually installed outdoors, exposed to wind and rain, and long-term exposure to the outdoor environment, dust and debris will inevitably adhere to it, putting it on "thick clothes", causing it to Reduction in power generation efficiency.


  In addition, the load resistance formed by partial shading will reduce the power generation, and doing so for a long time may even cause combustion and fire, causing unnecessary trouble.


  Regular inspections of fixing screws and brackets can also extend the service life of solar panels from other angles.


  I believe that everyone wants solar panels to keep their body better and generate better power!

  How should we maintain and maintain solar panels


  First: In terms of time, generally choose to clean the solar panels in the morning or evening when the sunshine conditions are not good.


  Second: Before cleaning the solar panel, check whether the solar panel is damaged, and whether its connecting wires and related components are damaged and stuck;


  Third: Do not use hard and sharp tools or corrosive solvents and alkaline organic solvents to wipe the solar panels, try to choose some soft tools such as sponges, cotton towels, etc.


  Fourth: It is necessary to pay attention to the cleaning of the entire panel, especially the corners where dirt is easy to accumulate, to avoid the load resistance formed by partial shading, which affects the power generation efficiency.


  At the same time, it should be noted that if the solar panel is fixed by screws, the screws need to be checked regularly. Although many screws have good oxidation resistance, long-term exposure to snow and rain may affect the screws. Regular inspections are required to ensure that the installation is firm.


  In addition to maintenance and cleaning, high-quality cells are also the guarantee of power generation efficiency


  Actually, we consider the influence of various environmental factors and installation factors on the premise that the solar cells must be brand new and excellent.


  If it is not a brand new and high-quality battery, but other first, second, and third-level batteries on the market, there will be color difference, stains, water marks, fingerprints, damaged positive electrodes, scratches, chipped edges, and missing corners. And other problems, resulting in power loss. You bought a 100W solar panel, but in fact it is less than 100W. No matter how you maintain it, its power generation effect is still greatly reduced. In some cases, the hot spot effect may cause gradual heating, short circuit, and burning danger.


  The superior battery does not contain any excessive electrical performance or poor appearance, ensuring sufficient power generation efficiency, fine and standardized production process, protecting the battery from damage, 100% EL test, no hot spots, and PID potential induction attenuation, Tensile, bending, glare, temperature, and smoke tests are used to ensure the power generation efficiency and life of solar panels under long-term movement, shadows, high temperature, high humidity, low temperature, wind and snow.
