Portable solar panels typically last between 10 and 25 years, depending on cell quality, outdoor exposure, folding frequency, and maintenance. Proper maintenance, care, and protection against environmental factors can help extend the lifespan of portable solar panels. Compared to stationary rooftop panels, portable models experience more movement and exposure — but that doesn't mean they can't go the distance. However, it's worth noting that their efficiency decreases by around 20% during this time period, which means they will continue to generate energy, albeit at a lower rate.
