Hi guys,
I'm working on what I thought would be a simple project - A solar powered dehumidifier and air cooler. I have a collection of peltier coolers and have been experimenting with various small solar panels and was getting results.
So.. I bought a 100W panel (http://www.ebay.co.uk/itm/2610695128...%3AMEBIDX%3AIT) thinking I could just connect it to a couple of peltiers in series to get the voltage below the maximum but it's not working out. The peltiers get hot very quickly (I have a big heatsink) and the voltage goes up outside their recommended level.
I think to start I need to control the voltage and have been looking at voltage regulators online but they all seem to be designed for charging batteries and I just want a direct connection to the peltiers.
So what do you think I should look at doing? My friend says I'm trying to make a car without a gearbox!
Thanks,
