Unlock the secret to sustaining peak photovoltaic module performance. Learn how Credence Solar’s Reinforcement Ribs solution thwarts glass sag, bolstering long-term efficiency and durability.
The sagging or deflection of the glass cover of a photovoltaic (PV) module can have several negative effects on the module’s performance and lifespan. Here’s how sagging can impact PV modules
Microcrack Formation: The stress applied to the solar cells due to glass sagging can lead to the formation of microcracks in the cells' semiconductor material. These microcracks can impair the affected cells' electrical performance and reduce the module's overall power output.
Moisture Infiltration: A sagging glass cover can allow moisture to infiltrate the module, potentially compromising the integrity of the edge sealant materials and electrical components. Moisture ingress can lead to corrosion, delamination, and electrical failures, negatively impacting the module’s reliability and lifespan.
Reduced Structural Integrity: Glass sagging can also compromise the module's structural integrity. The module may become more vulnerable to mechanical stresses such as wind, snow loads, or hail impacts, increasing the risk of physical damage and reducing its lifespan. Cracks generated in the sealant between the glass and frame may also lead to moisture ingress.
Ease of Handling : The ribs provide additional strength making it easier to handle without damaging or stress on sensitive components like PV Cells and glass. This is important during installation and maintenance
Hence, consider the best product and solution for your investment in the long-term benefit rather than looking for short-term gain. Here are the solutions from Credence Solar panels with Reinforcement ribs for better mechanical rigidity, avoiding the sagging of glass and robust solution.
