Quick Answer
Flexible solar panels can last for up to 25 years, depending on the quality and environmental conditions. Signs of deterioration can be subtle, but they are critical to identifying potential issues before they become major problems.
Identifying Physical Damage
Flexible solar panels are more prone to physical damage than their rigid counterparts. Cracks, cuts, and creases can reduce their efficiency and lifespan. Check for any visible signs of damage, such as tears in the laminate or exposed wiring. Inspect the panel’s surface for any scratches or dents that could compromise its water-resistance or electrical connections.
Measuring Efficiency and Voltage
Regularly check the panel’s efficiency by comparing its output to its rated capacity. A 10% decrease in efficiency can be a sign of deterioration. Use a multimeter to measure the panel’s voltage and current output to ensure it’s within the manufacturer’s specifications. Compare the results to the panel’s certification documents to determine if any changes are within acceptable limits.
Environmental Signs
Environmental conditions can also affect the lifespan of flexible solar panels. Check for signs of water damage, such as discoloration or corrosion, which can indicate a breach in the panel’s water-resistance. Also, be aware of extreme temperatures, which can affect the panel’s efficiency and lifespan. Monitor the panel’s performance during periods of high temperatures or humidity to identify any potential issues.
