A small solar generator system, with power-matched components, has been designed and tested. The system consists of a 255 W module with 60 crystalline silicon cells in series (156 mm), feeding a charge controller with maximum power point tracking capable of delivering 20 A of charging current to a 12 V, 100 Ah (1200 Wh of energy) deep-cycle lead-acid battery, which powers a 1500 W pure sine wave inverter. The power efficiencies of the charge controller (PV in to battery out) and the inverter (battery in to AC out) were measured to be 90% and 93%, respectively, for a total system efficiency (PV in to AC out) of 84%. An AC-powered battery charger is also provided to automatically supplement the PV charge controller, as needed. The module can be mounted on a vertical wall, with a tilt mechanism which allows a choice of discrete tilt angles for different seasons. The system is expandable up to eight modules and charge controllers for significantly increased energy production and storage. A heat transfer analysis suggests the module power output can be increased by 6% (relative) if passive cooling fins are applied to the back of the module.
