What is the lifespan of a PV system?
Solar Electric systems last a long time depending on the amount of active use, or the amount of sunshine converted into electricity by the PV cells. Most systems are only in use for 6 to 8 hours per day. Manufacturers will usually provide 10 to 20-year warranties, but PV modules will likely last longer than that. The balance of system components, however, will have a shorter life.
