How long do solar panels actually last? Solar panels offer homeowners a great way to reduce their carbon footprint. Luckily, the lifespan of solar panels will allow you to produce energy for many years, providing a great return on investment. You can count on most photovoltaic solar panels to last 25 years before they begin to noticeably degrade. Most solar panel companies will provide a standard 25-year warranty for the expected life expectancy of the solar panels. After 25 years, your solar panels won’t necessarily need to be replaced; however, their ability to absorb sunlight will be reduced. What is solar panel degradation rate? Over time, solar panels lose their ability to absorb sunlight and convert it into solar energy due to factors such as hotter weather and the natural reduction in chemical potency within the panel. This is what is referred to as the “degradation rate”. The lower the degradation rate, the better the panel. When a solar panel has a lower degradation rate, i
