In this work, an efficient autonomous solar energy system has been implemented for domestic use. It concentrates the solar heat to turn water into steam which in turn is channelled to drive an electricity turbine-generator. The prototype utilizes two heliostat reflector units, each of which has been designed to accurately and independently track the sun throughout the day and reflect its light constantly on a water tank through a Fresnel lens. The algorithm is flexible enough to accept up to 100 units and can accommodate the four seasons of the year. The performance of the system including the instantaneous generated power can be monitored wirelessly using a specially designed Computer User Interface. The final system produced a concentration efficiency of 86%-92%.
