How long do solar panels last on average?

As an American homeowner with a solar panel system, it is a valid concern. Your solar panels represent a hefty investment. Learning about the solar panel lifespan is a must to avoid surprise bills later on.

In this guide, we will discuss the average lifespan of solar panels. Read on and find out whether your investment is worth your money:

How Long Do Solar Panels Last on Average?

Most experts agree solar panels will last between 25 and 30 years. However, it represents solar panel degradation. After all, the panels will continue to make electricity.

After 25 years, your solar panel efficiency over time decreased by a significant amount. It applies even when they sustain no physical damage from wind, debris, and other external factors. They lack moving parts, meaning only a poor racking setup or extreme weather can break them.

The average solar panel system will decline by 0.8% every year. However, high-quality panels from Blue Raven Solar enjoy lower rates. It ranges from 0.3% to 0.5%.

How to Increase the Reliability and Lifespan of Solar Panels

The best way to extend your solar panel lifespan is to get a reputable installer. Ensure they offer warranties for the equipment. Most panel makers have 10 to 12-year policies for covering either defects or environmental damage.

Reputable manufacturers also offer production warranties. In most cases, they will last around 25 years. It guarantees consistency, ensuring your panels make at least a specific amount of energy for the duration.

Maintaining your system lowers its degradation rate every year. Here are some simple tips to improve its longevity:

Regular Expert Check-ups

Get your installer to examine your solar power system regularly. Doing so can reveal various issues like exposed wires or loose racking. Never do it on your own since you might void your warranty.

The inspection will likely include other related solar equipment, like your solar inverters. On average, a central inverter will last from 10 to 15 years. You will replace them at least once during your solar panel lifespan.

A popular alternative is to invest in micro inverters. They often last as long as your solar panels.

Clear Debris from Your Panels

During your first installation, the contractor ensures you have no large trees nearby. After all, these can cast a shadow or drop branches on the panels.

Consider investing in specialty products to prevent physical damage to your solar panels. An example is the solar panel critter guards. It prevents tiny animals like birds and squirrels from nesting under the panels.
