Should I Replace My Aging Solar Panels?

This article from Mother Earth News addresses the question of whether aging solar panels need to be replaced. The author advises readers to check the warranty provisions for their specific solar panels, as most companies offer a performance warranty of 25 or 30 years. While some panels may experience a significant drop in performance in the first year, they can still produce usable levels of power for 50 years or more. The author suggests keeping the panels until they stop working or a warranty claim needs to be made, as the likelihood of failure is higher due to moisture damage rather than natural wear and tear. Additionally, if more power is desired, the author recommends adding another solar array to complement the existing one. [Extracted from the article]
