Proposta de um sistema de iluminação utilizando baterias recicladas alimentadas por painéis solares fotovoltaicos

Abstract

The present academic work of graduation in Environmental Engineering has as general objective The assembly of the off-grid photovoltaic system, being designed and built the panel and the batteries both implanted in the system, with the intention of generating electricity for powering lamps. For studies of the efficiency of this system and the capacity of recharged batteries, quantitative tests were generated to know the duration in hours of feeding the part of the batteries without the solar radiation, ie only with the energy stored by the batteries during the day / afternoon period. Thus, it is possible to have an efficient system that gives a concrete and correct destination for batteries that are considered hazardous waste because they contain highly toxic and non-biodegradable heavy metals such as cadmium, lead and mercury, which are extremely dangerous to human health; in a way that is more popular and low cost this system, taking into account the social return that the access to electric energy provides, the use of photovoltaic cells can become an important means of social promotion, especially for the more distant regions of urban centers.
