Why Solar Hybrid?

Supply from National Grid:• High cost – far from grid system (current distance considered for grid < 5km) –• Not available – remote

Diesel Stand Alone (Genset):• 6 to 12 hour supply• High fuel cost and consumption• High Operation, Maintenance, Repairs &

Replacement Cost (OMR&R) • Low reliability

Operational problems;

Disadvantage of Stand-alone Genset

Generator set starting failure, requires unscheduled site visits/permanent manpower for fault rectification. Generator engine life also proved unsatisfactory. For isolated areas, fuel logistics and handling will increase operational costs.
