Longevity
Monocrystalline solar panels have proven themselves durable and long-lasting. In fact, some of the early modules installed during the 1970’s are still producing solar electricity until this day. A number of solar websites even suggest that monocrystalline solar panels can last up to 50 years with solar engineers backing it up by saying that it may only have a slight efficiency drop off of around 0.5%. Many monocrystalline solar panel manufacturers claim a lifespan of 25-30 years, but as long as the PV panel is maintained and kept-clean , it will still have the ability to produce power.
