A functional 1.5KVA Solar Electricity Power Generation capable of powering 6 computer systems with printers, lighting points, fans as well as 3 television sets is presented. The system comprise of 2 solar panels each rated 55W, 18V was designed to work in the range of 50-55W, 12-18V. Two storage batteries rated 200A, 12V are used. The inverter is a modified square wave. There is built in charge control unit and charge with control. The auto power switching was placed between the mains solar panel and battery. Thermally controlled cooling fan made of thermistors and mode indicators is used to ensure that the system is not overheated. The systems working efficiency was found to be between 70 – 75%.
