Solar panels are guaranteed to last 25 years, the inverter which turns DC in AC is guaranteed to last 10 years. We did ours under a govt scheme (14 panels) and sell back any unused power. We get about £1500 back but we got in early as I don't think the pay is as good as it used to be, but if you are a big electric user its worth doing. Make sure to get quotes from 3-5 companies as the installation could vary alot. We don't regret getting ours done.
