How long solar panels can last and 3 tips to extend their lifespan

How long solar panels can last and 3 tips to extend their lifespan

With the rising demand of solar panels, the federal tax credits and additional rebates have lessened, identifying the cost of solar panels becomes crucial. Prompting that solar panels last for decades, and designed like that it can last longer than usual. Here in this blog we will understand the factors that affect how long solar panels can last and tips to last them long.

Factors that affect how long solar panels can last:

1. Manufacturing quality:

The quality of materials used in manufacturing solar panels significantly impacts their lifespan. Look for solar power companies in Arizona that uses high-quality panels because panels, constructed with durable materials and advanced technologies, tend to last longer and perform more efficiently over time.

2. Environmental conditions:

Solar panels are designed to withstand various environmental conditions, but extreme weather can take a toll on how long solar panels can last. Factors such as temperature fluctuations, humidity, and exposure to harsh elements can affect how long solar panels can last.

On average, solar panels have a lifespan of 25 to 30 years. As they approach the end of their lifespan, their efficiency gradually decreases. It’s advisable to consult with a professional to assess the condition of your panels and consider replacement when efficiency drops significantly.

Do solar panels degrade over time?

Yes, solar panels do experience degradation over time. This is a natural process where the efficiency of the panels decreases gradually. The rate of degradation varies depending on the type of solar cells used. Traditional silicon-based cells typically degrade at a rate of around 0.5% per year, while newer technologies may have different degradation rates. Regular maintenance and monitoring can help mitigate the impact of degradation and extend the overall lifespan of the panels.
