Slightly off the topic -
Off grid solar power is unviable at the moment in terms of cost.
-
There are no subsidies from the government other than on solar pumps.
-
Off grid system needs batteries, which augments the overall cost of solar powered system. Makes it unviable in terms of cost.
-
On grid system is the only mode which is viable in term of cost, but is of no use in areas where there is major supply disruption. (For instance, i am planning to set up solar powered system on my farm, but we only get 6 hours of power daily). So, on grid system is of no use …as whatever my system is generating will go straight to grid; on the other hand, i am only getting grid power for 6 hours.
