Abstract

This work implements a solar power battery energy storage system (BESS) with maximum power point tracking (MPPT) under substantial variation in temperature and intensity of illumination. A tracker is also designed based on the perturbation and observation method to track rapidly the maximum power point of the energy output of the solar cells. The power generation data are then transmitted to computers via RS232 for analysis. Next a battery charger is developed using a dsPIC30F chip. Additionally, the maximum power is output following a photovoltaic transformation by varying the illumination intensity. Moreover, the power generated by the solar cells is fed back to the lead-acid battery to supply the load.
