A solar generator is a small capacity,
stand-alone SPV power system based on a PV array, connected
to a battery bank and an inverter of appropriate size.
This system is designed to supply power to limited loads
(such as lights and fans) for a period of two to three
hours daily in situations such as conventional power
failure or load-shedding. The MNES currently promotes
four models of solar generators, with capacities of
150, 350, 450, and 600 Wp. These solar generators are
mainly meant to replace the conventional small-capacity
petrol-based generators that are used during routine
load-shedding periods in urban areas by shops, clinics,
and other small establishments.
The components of a typical solar generator are a small
SPV array connected to a battery bank of appropriate
size and an inverter based on 12, 24, or 48 V. The system
is designed to supply power to loads such as lights,
fans, credit-card operating machines, and personal computers
for a period of two to three hours.
Advantages
Small, portable solar-po wered gen erators have unique
advantages that make them a flexible energy solution
that is both economically viable and environmentally
relevant. Electrical energy requirements in remo te
locations can necessitate importing heavy gas/diesel
generators. These are often noisy and their use is limited
to the amount of fuel available. Where importing or
transporting fuel is costly or inconvenient, solar can
provide aflexible solution that is noiseless and smokeless,
and the fuel is free. In some situations, the payback
period for these units can be rema rkably quick.
The use of solar in remote locations eliminates the
possibility of environmental contamination from the
spilling or leaking of fuel, which can contaminate ground
and surface waters and elevate risks of forest fires
and property fires. The emission of pollutants and greenhouse
gases from traditional fossil-fuel generators has negative
effects on air quality and in linked with global warming
and climate change.
Cost
The cost of the four solar generator models promoted
by the MNES varies from Rs 35 000 to Rs 145 000.
