With the increasing concern of green-energy over the world, solar PV industry has well developed in Taiwan. However, the materials in use for solar cells will make a difference in efficiency, capacity and cell size. Therefore, the primary target of this thesis is to measure what the differences between the poly-silicon and thin-film solar cells through an independent charger on the same solar power energy, angle of elevation and ambient conditions. An assessment of the whole working procedure of solar cells will be established by recording its maximum power generating capacity. Furthermore, this dsPIC30F Microchip achieves an independent-type electrical charge and measures the power capacity through the RS232 to make the analysis and comparison by a computer.
