Solar panels should last at least 25 years, however this doesn’t mean they simply stop working after that time.
Solar panels can continue to generate electricity for decades, it’s simply the efficiency of the panels that tends to start declining. In other words, the amount of electricity the panels produce will start to drop off.
Solar panels last so long because they have no moving parts and are designed to withstand potentially harsh outdoor conditions. Assuming they don’t sustain any physical damage from the elements – think wind, hail storms and debris – solar panels have been known to last 30 or even 40 years!
The part of your solar system that is more likely to fail before then is the inverter. The inverter converts the energy produced by your solar panels into electricity that can be used in your home or exported to the electricity grid.
Unlike the panels, the inverter works hard all day, so is the part of your solar system that is more likely to fail within the first 10-15 years of your solar installation.
For this reason, inverters tend to come with a warranty of 5-10 years while solar panel performance warranties are up around 25 years.
