Recurring Consumption Cost |
Low recurring cost for battery bank only being 50% less compared to Elec. board ranging between Rs. 2 to Rs. 3 per KW |
Rs. 4 to 6 per KW |
High level recurring cost of Battery Bank ranging between Rs. 6 to Rs. 8 per KW. As solar energy is available for maximum average 5.5 Hours. |
