Reasons Why Solar Panels Degrade
Just like gadgets and machines, solar panels don’t operate at their optimal capacity all the time. That means they become less efficient as time passes by. You may be wondering why solar panels degrade. Many factors influence the rate and degradation speed of solar panels such as manufacturing, installation, or maintenance. Continue reading to better understand why solar panels degrade.
What Solar Panel Degradation Is
Solar cells lose the ability to collect sun energy gradually as time goes by. So, they become less efficient. This occurrence is termed degradation. Most solar panels have a warranty of 25 to 30 years. However, they can last longer depending on the design, quality of the materials, and maintenance. A good solar panel has a 0.5% to 3% degradation rate on average during its lifetime.
Factors That Affect Solar Panel Degradation
Below-par materials in a solar panel can cause many issues such as decreased efficiency and lifespan and more maintenance expenses. Also, the assembly quality of solar panels can affect degradation since some components don’t work together well if not arranged properly. That’s why it’s always best to pick a quality and certified solar energy provider.
Solar panels that aren’t installed properly can result in electrical problems such as electrocution and fires. Though they are durable and can resist pressure, these can be compromised if the installation was done roughly. There can be microcracks and more corrosion and water ingress. This can result in a system breakdown. If the wiring isn’t done right, you’ll likely have efficiency and performance problems with your system.
Dust buildup on the glass can lessen the power produced and affect local hotspots. Bird droppings and emissions from factories can also play a role in solar panel degradation. How severe the damage depends on how discernible the foreign objects are. So, you must check and inspect your solar panels regularly.
You should check the connections, cables, and inverters carefully and make sure that they’re not damaged or broken. When you do this, you can enjoy the maximum output and prevent issues in the future.
Ways to Extend Your Solar System’s Life
Solar panel degradation is inevitable. Solar panels don’t exist forever. But, there are things you can do to increase their lifespan. One of the most effective ways to do this is to opt for quality solar products and services from a reputable solar energy company.
Generally, low-quality materials are tempting because they’re less expensive. However, you can end up spending more in the future because there’s a higher failure rate which means you have to replace cheap solar panels sooner. When picking solar panels, you have to remember that their price plays a big role in their quality.
