How Long Can a Solar Panel Last?
The life of a solar panel plays a part in how much you gain over time in electricity savings. If your panel has a short lifespan, you’ll have less time after the payback period to reap savings before having to purchase a new panel.
Monocrystalline Solar Panels
These are the most common and effective type of solar panel available today. And, while most panel manufacturers offer 25-30-year warranties, these panels could last up to 40 years or more.
Polycrystalline Solar Panels
Polycrystalline solar panels are also a popular choice for solar energy. However, they aren’t as effective as monocrystalline panels, and often degrade faster. These panels often last 25-35 years.
Thin-Film Solar Panels
These panels are less effective than the other two choices, and they also have a shorter lifespan. If you choose to install thin-film solar panels on your home, expect them to last 10-20 years.
So, is solar a good investment still? If it takes you 10 years to recoup your expenses, you’ll still have 25 years to make money on the system and benefit from the upgrade — so we say yes! Just remember that your payoff period may vary depending on fluctuating electricity costs, the efficiency of your solar system, and your personal energy consumption.
