Getting Continuous Electricity for a Home

1kW will cost about LKR 175000. this is to get approximate idea about cost. 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.

I had a chat with these guys, if you only go for Solar (Without batteries) you will only have power when there is power in the main line. i.e. during a power cut you will not have power even during day time. If you want to have power even during a power cut then you need to buy some batteries and look at a hybrid setup.

That is what i have said when i upgraded to 5 kw i changed to a diffrent inverter which also support off grid as well as grid tie capabilities .
As for the return s the system has coverd it cost. I useed to get electric bill around 22000 per month so the system cost os already covered
