Do Solar Panels Stay Efficient Over Time?

Solar panels are a key component of any solar energy system, and it’s important to understand how they can degrade over time. Degradation refers to the reduction in a solar panel’s ability to produce electricity, and it can occur for a number of reasons.

What Leads to Panel Degradation?

One of the main causes of solar panel degradation is exposure to the elements. Solar panels are exposed to a wide range of weather conditions, including extreme heat, cold, and UV radiation. These conditions can cause the panels to degrade over time, reducing their efficiency and output.

Another cause of solar panel degradation is the accumulation of dirt, dust, and other contaminants on the surface of the panels. These contaminants can block the sun’s rays from reaching the solar cells, reducing the panel’s overall efficiency.

Another factor that can contribute to solar panel degradation is the age of the panels. Like any other device, solar panels will eventually wear out and become less efficient over time. Most panels are designed to last for 20-25 years, but their actual lifespan can vary depending on a number of factors, including the quality of the panels, the conditions they are exposed to, and how well they are maintained.

Dirt, dust, leaves, and even bird droppings can all block the sun’s radiation from effectively reaching your solar panels. This not only reduces the total wattage reduced, but may also contribute to panel degradation over time.

Limiting Panel Degradation

Fortunately, there are steps that solar panel owners can take to minimize degradation and extend the life of their panels. Regular cleaning, inspection, and maintenance can help to keep the panels in good working order, while proper installation and protective measures can help to minimize the impact of the elements.

Overall, solar panel degradation is a normal and expected part of the life cycle of a solar energy system. Understanding the causes of degradation, and taking the proper steps to minimize it, can help solar panel owners reduce the amount of degradation over time.

Ultimately, however, the most important decision in limiting panel degradation may just be panel itself. Choosing the right solar panel that is built to last against the elements and withstand breakdown over time can make a giant difference in your ability to efficiently produce clean, reliable energy.

Choosing the Right Solar Panel
