On average, the lifetime of an inverter is between 10 and 15 years, depending on the make, model and environmental factors. This is shorter than the lifetime of solar panels, which are usually 25 to 30 years last.

Factors affecting longevity:

• Inverter quality – Premium brands such as SMA, SolarEdge and Fronius last longer.
• Environmental factors – Extreme heat, moisture and dust can shorten the lifespan.
• Maintenance – Regular inspection and cooling extend the service life.

Over time, the efficiency of an inverter decreases, which can lead to lower yields. Timely replacement ensures that your solar installation continues to perform optimally.
