What Makes Solar Panels Durable?

With their low profile and shiny glass surface, solar panels might look fragile. Despite appearances, however, solar panels utilize sturdy materials and thoughtful engineering to provide exceptional strength and reliable, cost-effective function for many years.

Solar Panel Construction

A solar panel consists of three main components:

  • Solar cell

  • Glass outer cover

  • Aluminum frame

The solar cell is the delicate, energy-absorbing inner layer of the panel. Thick glass covers the solar cell, providing a barrier against the elements while still allowing sunlight to pass through. The frame provides a stable structure for the panel, and the aluminum material is strong, lightweight, and resists rusting.

Typical Solar Panel Lifespan

Many manufacturers offer a 25-year warranty on their solar panels, so you should get at least that much time out of your investment. Your panels will probably function for many years past the warranty expiration, but the active components in the solar cell will lose efficiency over time.

The underside of the panel is the most vulnerable to damage, so having your panels properly installed by an experienced provider is key to optimal function and longevity.

Solar Panels and Inclement Weather

Thanks to their multi-layer construction and watertight design, solar panels may prove to withstand inclement weather better than your actual roof.

Hail up to 1 inch in diameter and accompanied by winds up to 50 miles per hour shouldn't cause any damage or compromise your solar array's performance. Most solar panels can also tolerate wind speeds of up to 140 miles per hour.

Bottom line: Installing solar panels is a great way to reduce your energy consumption and electric bills over time, but it's wise to make sure that your investment will pay off in the long run. Thanks to durable materials and meticulous design, you can look forward to reaping the benefits of solar energy for many years to come.
