The long-term durability of PERC solar panels is another advantage that sets them apart from conventional solar panels. The passivation layer added to the rear side of the cell not only enhances efficiency but also provides additional protection against environmental factors such as moisture, dust, and UV radiation. This added protection contributes to the overall longevity of the panel, ensuring that it continues to generate electricity efficiently for an extended period. With a typical lifespan of 25-30 years, PERC solar panels provide a reliable and long-lasting renewable energy source for homeowners and businesses.
