Dear u should also write its disadvantages

1) It works if 12 hours a day ( If u didnot put battries)

2) It doesnot work in the cloudy Atmosphere it is ignorable because pakistani climate is mostly sunny.

3) It needs high investment initially (i approximated 35000rs for solar panel which will work 8 hours a day with 3fans and 4tubelights, so if we estimate whole house including refrigerator and water motor then it will be of 5 lacs for 8 hours only, So it is very much costly)

4)You should change the panel after a decade.
