Abstract
Residential electricity consumer can rent a photovoltaic power generator, whose profit can be exist if the decreased electric fee is larger than the rent fee. But the exact function of the profit have not expressed until now, which is shown in this paper. Two assumptions are supposed. The first assumption is that the generated electric power by the renting photovoltaic generator is 300kWh per month. The second assumption is that the rent fee 362300 won is paid once when the photovoltaic generator is installed. The earings rate, the payback time and the sensitivity of a low-voltage residential electricity consumer's profit consuming 401~1000kWh per month at a detached house for the initial 7 years is calculated by the induced exact function.
