    Please mail me the exact circuit diagram ... and can we use AT89C51 microcontroller instead for the control unit ... also if there's any report u have as to why we have used 9W solar panel thanks

    Schematics and the diagram shown in the step 4 aren't similar ... where are the diodes? please help us with the actual circuit. "URGENT"
