Solar panels represent one of the most durable and reliable home energy investments available today. With typical lifespans of 25-30 years and continued electricity production for decades beyond, they offer exceptional long-term value for homeowners committed to clean energy and energy independence. Essential Lifespan Factors to Remember:
There are a number of ways to prolong solar panel lifespan such as regular maintenance, cleaning and repair, all of which increase their functional lifespan. The lifecycle of a solar panel naturally includes the steady loss of efficiency over several years of use.
No, solar panels are still useful after their lifespan. Solar panels still produce power, but at a slower rate, even though their energy efficiency gradually decreases. Older solar panels are donated to organizations with limited access to electricity or used for less essential purposes to extend their useful lives.
How Efficient Are 10-Year-Old Solar Panels? Given the typical degradation rate of about 0.5–0.9% per year, a 10-year-old solar panel can be expected to retain 90–95% of its original efficiency. This means that if a solar panel started with an efficiency of 20%, it should still deliver around 18-19% efficiency after a decade.
Conclusion Solar panels are expected to last 25 to 30 years. However, considering the current and projected costs of electric power, the rapidly falling costs of PV panels and the increasing
