During the first 10 years, the electric production decreases of 5-10%; however, after 25-30 years the solar panel still produces 80-85% of the starting electricity. Basically, if you correctly use electricity, the money saved is an advantage that lasts 30 years, and – considering the increase of the energy costs – it will reassess during time!
