6 FAQs about [What to do if there are hidden cracks in photovoltaic panel installation]
How to prevent solar panel micro-cracks?
Three key areas must be addressed to effectively prevent solar panel micro-cracks: manufacturing, transportation/installation, and environment. Selecting a solar panel manufacturer that acknowledges the prevention of micro-cracks is a critical part of the solution.
What causes micro cracks in solar panels?
Even slight imperfections in the PV cell can lead to large micro-cracks once it is incorporated into the PV module. The length of micro-cracks can vary; some span the whole cell, whereas others appear in only small sections of a cell. Micro Cracks in Solar Panel How do micro-cracks occur?
How do I choose a solar panel manufacturer?
Selecting a solar panel manufacturer that acknowledges the prevention of micro-cracks is a critical part of the solution. Minimal human intervention, appropriate training, and guidelines for unpacking and repacking modules are all crucial to preventing micro-cracks.
Why are solar PV cells prone to micro-cracks?
The silicon used in solar PV cells is very thin (in the range of 180 +/- 20 microns) and hence is susceptible to damage easily if the PV module's production and handling are not up to the required standards. Even slight imperfections in the PV cell can lead to large micro-cracks once it is incorporated into the PV module.
Do solar panels need El testing?
Therefore, visual checking of PV modules alone is not an effective method to identify micro-cracks and should not replace a thorough EL test. When you are purchasing solar panels, you should conduct EL testing on your panels and have them properly, safely packed before giving green light to the shipment.
How can sinovoltaics help you in importing solar panels?
When you are purchasing solar panels, you should conduct EL testing on your panels and have them properly, safely packed before giving green light to the shipment. If importing from the Greater China region, Sinovoltaics can help you by performing independent quality inspections on-site at solar manufacturers.
