You will get 5 years warranty for inverter. this will not cover damages due to lightening. so you have to go for small insurance scheme to cover such a damage. normally effective generation time is 5 hrs per day. also orientation of your roof need to be checked. solar panel need timely cleaning.make provision for it. speak with guys about no of strings which connects individual panels to the system. higher the no of strings, it will give less impact to generation when one panel is faulty. i have seen many systems will be payback in less than 5 years.</blockquote>
