One of the factors that can affect the lifespan of your panels is the degradation rate. Over time, solar panels can degrade due to exposure to sunlight, heat, and moisture. Solar panel degradation rate varies among brands and models from less than 1% to over 5% annually. The measurement quantifies the amount of power loss per year.
Another factor that can affect the lifespan of your solar panels is efficiency. Solar panel efficiency is a measure of how much electricity the panel can produce from the sunlight that hits it. The higher the efficiency, the more electricity your solar can produce, and the longer they will last. High-efficiency solar panels can last up to 30 years or more, while lower-efficiency panels may only last 20 years or less.
In addition to the panels themselves, the lifespan of your solar power system will also depend on the inverters. Inverters are a crucial component of your solar power system, as they convert the DC electricity produced by your solar panels into the AC electricity that powers your home. Inverters typically have a lifespan of 10-20 years, so you may need to replace them at some point.
So, how long can you expect your solar to last? It really depends on a variety of factors, including the brand and model of your panels, the efficiency of the panels, the degradation rate, and the lifespan of the inverters. While most solar panels come with a 25-year warranty, many panels can last much longer than that. Solar panels require maintenance and care, your solar panel system can provide you with clean, renewable energy for decades to come.
In reality, solar panels can last much longer than 25 years. The NREL found that most solar continue to produce energy at a reduced rate after 25 years, with some panels still producing 80% of their original output.
