The Durability of a Solar Panel: Strengths, Weaknesses and Troubleshooting

The Durability of a Solar Panel

Solar panels allow you to harness the sun’s power to provide clean energy for your home or business without fossil fuel combustion. Over the last decade, solar panels have become one of the most reliable and sustainable ways to power homes and buildings of all sizes.


To the naked eye, solar panels sometimes look like they would shatter under the slightest amount of pressure. In reality, the superior design of solar panels makes them highly durable.

The Design

Solar cells are made of crystalline cells and at only a few millimeters thick, they are very fragile. Solar panels are made up of several solar cells with a frame around the edge to protect the cells. If the cells were left exposed they would crack too easily, so instead, most of today’s high quality solar PV panels come equipped with protective laminate, acrylic, or glass casing.



Lack of moving parts is one reason why solar panels are very durable. Carefully designed for exterior use, solar panels are able to withstand wide ranges of temperatures, weather conditions, and outside factors. They are rigorously tested to stay strong against tree limbs, hail storms, 120+ mile per hour wind, and more.


To prevent overheating or cracking under cold temperatures, panels come equipped with special controls that keep them operating at even temperatures.


Potential Issues

Panel placement and location can affect durability, so panels should be kept away from areas that are prone to damage, such as from falling rocks or trees. If you are using stand-alone system instead of a roof setup, you should also consider the damage that can be caused by animals and people, especially if the panels are close to the ground. Panels that are subject to curious animals or errant baseballs could experience compromised longevity. Also, solar energy systems are not able to withstand natural disasters such as hurricanes, tornadoes


Solar panels are not impenetrable. Generally, if it will break your roof, it will more than likely break your solar panels. Still, not bad for materials that look as though they are made of glass. With regular maintenance, the actual panels themselves typically will last over 30 years.


Maintenance and Repairs

The Department of Energy projects that for optimal longevity anywhere from eight to 16 hours every year can be spent maintaining a solar panel system. Some of the most basic steps include rinsing bird droppings and dust off the panels, but it’s important to only have experienced professionals work on your solar panels or roof, as an inexperienced person could accidentally cause damage.


In the rare chance that something goes wrong with your system or if your system has a broken panel, it’s best to contact the installation company. The solar panel system could still remain fully functional even if the glass breaks.


The design of photovoltaic cells has remained impressively durable and resilient, well-equipped for stationing on your roof or property against the elements. Trust your energy needs to the sturdy panels of 1st Light!
