A typical solar panel lasts for about 25 to 30 years. And during this period, most of the photovoltaic (PV) systems require little to no maintenance. However, the lifespan of your rooftop PV system depends on the technology, panel quality, and installation. Usually, solar arrays lose only 0.5 percent each year when it comes to performance. Even after using them for 25 years, they usually keep operating at an efficiency rate of 90 percent. Read this post to learn more about the durability of PV systems.
Solid Outer Layers
Though most PV systems have fragile conductive plates inside, reputed solar manufacturers design robust outer layers for increased durability. Whether you have opted for a rigid material or tempered glass, the outer layers are extremely resistant to adverse weather, high winds, debris, branches of trees, and hail.
Lifespan of Solar Systems
The durability of solar panels varies from one model to the other. However, purchasing panels from a reputed vendor will ensure that they last for about 25 to 30 years. Although solar panels do not cease to function, they do start to degrade after the specified period. That said, you don’t need to replace a PV system once it crosses the 25-year threshold. You can easily continue using them as long as you save on your electricity bills.
Mono and Polycrystalline Panels are Efficient
Choose mono or polycrystalline panels because the rate of degradation is much lesser than cadmium telluride, amorphous silicon, and copper indium gallium selenide panels. The output loss is only 0.61 and .064 each year pre-and-post installations.
Improving Solar Panel Lifespan
Keep your rooftop safe from physical damage like tree branches blowing in the wind and scratching the panels. Install the solar panels in a safe position away from branches and sheltered from the winds. Clean the panels on a regular basis.
Take care of your solar panels, and they will take care of all your power needs. If you have a PV system that requires maintenance, feel free to consult with our solar technicians. We can help you with the installation of solar panels, solar pool heating system, and other solar products as well.
