The ampere-hour efficiency of photovoltaic solar generators

Abstract

The charging power and discharge power of two photovoltaic solar generators are measured simultaneously with the sunshine hours. A comparison of these two powers shows that there is sufficient power under the available local sunshine for lighting purposes. The ampere-hour efficiency of these generators is compared with that of lead-acid and nickel-iron cells. A 10% difference in the ampere-hour efficiencies for the two generators is observed.
