What is the lifespan of a solar panel system?
Solar panel systems last a long time depending on the amount of active use, or the amount of sunshine converted into electricity by the solar panels. Most systems are only in use for 6 to 8 hours per day. Manufacturers will usually provide from 10 to 20 year warranties for the solar panels, and a 5- to 10-year warranty on the balance of system components. Solar panels have been reported to last 30 to 40 years.
