Cost Considerations

This chapter discusses how to compare the cost of solar electricity against alternatives. Simple cost comparisons of solar electric systems are presented for kerosene lighting systems, dry cell powered cassette players, and conventional generators. Practices and devices that reduce the cost of systems are introduced, including modular approaches to system planning, methods of collecting and storing more power, and improvements to energy management.
