I built a small solar powered fan that worked well. I would like to increase the size of the fan.?

We Answered:

Essentially you are building a new one, first a larger fan, then a larger motor, then a larger solar array.

So keep the old one and buy or build a new one. You can buy plenty of motors online. Pick the voltage you will use for the solar array, say 6 volts, then look for a 6 volt motor. Check it's current requirements, and get enough solar panels to supply that current.

of course, they are in most toyshops, but try the CAT centre for a huge range of solar stuff (Centre for Alternative Technology in Wales)

I have a 12 volt solar battery charger and use it to charge a 12 volt battery and then run my fan and radio from the 12 volt battery. Car radio and car fan. Light also
