    I have a solar panel which gives a output of 8.42 v.
    I have to increase the voltage to 12v for LED lights and for other purposes.
    I need a step up circuit which makes the output of the solar panel to 12v.

    Thanks in advance...!!!

    Welcome to AAC!
    You need a DC-DC boost converter. Heaps advertised on the web. Cheaper to buy than to build.

    Welcome to AAC!
    Boost regulator as already mentioned.

    What is the current from the solar panel and what current do you need @ 12V?

    What is the nominal wattage of the solar panel?

    Assuming an efficiency of 90%, your solar panel can only provide about a quarter of the power you want.
