Solar Generators

Introduction

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.
