Get your 2 9 volt batteries and positive and Negitive wires plus the fan and solder the wires to the batteries and fan and solar panels.

Step 3: The Switch

Of course you have to add your switch to the circuits so solder that together.

If you are using a solar panel, wht are you using the 9 volt battery for because as far as i can see from the pics, its not a rechargeable battery and you havent said anything about any recharger circuit.

It's common sense for a person who has experience in circuitry. I don't know how you don't understand it.

Can u please draw a circuit cause i did not understand the wiring

But adding padding and create a new, more versatile helmet for hard hats will open the safety warranty for my instructable.

Really cool idea (no pun intended) but doing that to a hard hat will void the warranty and make it not safety approved
