Instructables

How can I run a CPU fan from a solar array? How big of an array do I need? This is to move air into a compost bid?

I need to move air through a Compost bin using PVC pipe via a CPU fan powered by a solar array
 Thinking 2 " pvc pipe

you don't need that much energy, 12v fan, using 0.5a = 6W of power
so you can probably use something like this:

maybe two of them?

Why do you need to move air around in your compost bin with fans and solar panels? People have been composting for thousands of years without electronics.... why start now? I don't mean to critisise, just interested. :D

Thanks for asking. We want to make compost as fast as we can as well as reduce smells. A venting system will do that as well when Summer comes will help control the heat so the Red Worms we will be using will not die off.
Please contact me at wclingman@wi.rr.com for more info and thanks again for your question!
