How long do solar panels last?

Your solar panels will continue to provide electricity for many years, possibly far beyond the 25 to 30-year lifetime of regular solar panels, as long as you can protect them from physical damage. You can also get specialized products to guard against particular physical harm to your panels.

How much do solar panels degrade a year?

The degradation rate of solar panels is calculated as a percentage. Experts estimate that most solar panels degrade at a rate of around 0.2% – 0.5% per year. This means that the output of usable energy generated by your solar panels slowly decreases over time.

How long does a solar inverter last?

A professional can also inspect your roof racking system and solar inverters with your solar panels. A central inverter for a photovoltaic (PV) installation typically has a lifespan of between 10 and 15 years. Therefore, it will eventually need to be replaced. However, micro inverters typically have a 25-year lifespan, the same as solar panels.

What is the energy payback time of a solar panel?

The energy payback time is when a solar panel generates enough clean electricity to “payback” the energy needed to create it. The energy pay back time (EPBT) of a solar panel is only six months, which has undoubtedly decreased over the past six years as panel manufacturing has become more effective.

Are solar panels durable?

Solar panels are generally very durable. Most solar panels are designed and tested to withstand the elements like hail, high winds, and heavy snow loads. And thanks to their lack of moving parts, solar panel systems usually require little to no maintenance. Still, maintaining your solar panels can boost production.

How to keep solar panels working over the long haul?

The best approach to keep your solar panels functioning over the long haul is to hire a reliable installer who provides good customer service and a labor warranty. As mentioned, getting high-quality solar panels with strong warranties is crucial to preserve your solar investment.
