This survey was designed following the progress of the use of solar energy. Madagascar is one of the countries that benefit enormously from this energy. As a result, many Malagasy people use photovoltaic cells for domestic and professional applications especially those who are outside the electrified areas. However, the used batteries last only 5 years or even 10 years at most, hence the idea of updating Thomas Edison's research in 1901, a nickel–iron battery technology which is distinguished by its long lifespan of more than 25 years. It is therefore a question of determining the chemical reactions involved into the battery, its aging process, its characteristics, its advantages and disadvantages compared to the lead–acid technology. Once the theoretical studies are carried out, the study proposes an application of nickel–iron technology in a photovoltaic installation in Madagascar.
