though i never said anything like that but i will add my comments now, one needs more than just Panels and batteries @
qamar1990 you need to have a large battery bank for this purpose and i have yet to see any pakistani company making batteries for such a large scale project. you just cannot use a acid battery in a projectt like this as they low life cycle. that why it is highly recommended to use Dry cell batteries, which i dont think any pakistani company is making.
if you want the best life cycle and battery life it would be better to import some good quality ones.
on the other hand it also depends on the quality of the panel we are using, two types of panel u have seen in market are Poly and mono coated.
we have setted up this project on our uncle's farm, we are successfully running a tubewell on solar energy. what we have done is added a VFD unit which converts the DC power coming drom solar panels directly to Tube well, rather than powering up the batteries first. when tubewell is not operational, the panels are charging the battery bank.
when it starts to get dark we switch it to battery bank which lasts through the night
