Solar panels generally have a long lifespan. Modern solar panels come with warranties that typically range from 20 to 25 years. This means that during this warranty period, the panels must maintain a certain level of performance and power. Most manufacturers generally guarantee a power reduction of no more than 80-85% of the original power after 25 years.
After the warranty period, solar panels can still produce energy, but performance may gradually decline. In practice, solar panels can last more than 25 years, and many installations still show considerable performance after three decades.
Various factors influence the lifespan of solar panels, including:
Quality of materials: High-quality materials and manufacturing processes contribute to a longer lifespan.
Installation quality: Professional installation according to the proper standards contributes to the system's durability.
Climatic conditions: Solar panels are designed to withstand various weather conditions, but exposure to extreme conditions can affect their lifespan.
Maintenance: Regular maintenance, such as cleaning the panels, can help maintain performance.
Manufacturer warranties: Reliable manufacturers offer long-term warranties, which can be an indication of the quality of the panels.
In general, you can expect solar panels to still have significant energy yields after the warranty period, but the annual yield may gradually decrease. It is important to pay attention to the warranty conditions and the reputation of the manufacturer when purchasing solar panels.
