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. . Depending on the manufacturer, solar panels' performance can be guaranteed for 25 – 30 years, but it's very possible that your panels will go on to produce electricity for longer than that. The results were reported by Chemistry World, a Royal Society of Chemistry publication. 25% degradation rates cost 10-20% more upfront, they produce 11. [pdf]
