Figjam's Swamp Cooler
A solar panel would have to have an output HIGHER than the amperage required for dc use. 12vdc requires 10 times the power that you get from 120vac. Also you'd better have four times as many 1" holes as 2" holes to flow the SAME amount of air.
It is more efficient to pull the air through the pads. Swamp cooler on rooftop houses do the same, pull in thru pads. Also a propeller fan is three times as efficient as a squirrel cage fan, uses 1/3 the power for the same cfm.

How to Make a Color-Changing Lighted Faux Fur Scarf
Would reversing the fan and pushing the air into the bucket and forced out through the pad make this work any better? I'm asking because I designed a similar system using a 48qt cooler and an inline fan pushing air into the cooler and out through a series of holes i drilled.

Not sure that is the case, and I sure want to know. if the h20 is cooler but not ice will that mean more evaporation perhaps even cooler evaporation by the warm dry air flow through and over the wicks, I believe so. of course a chunk of block ice wouldn't wick.Warmer water well the closer the water is to the ambient temperature less cooling.....correct?The drier the air the better, this I know.Some expert schooled in the sciences better that I please give us the science (outside of the relative humidity. will ice water work better at cooling in an evaporative cooler that water x degrees below ambient temperature or is there some ideal gap for the evaporation point of water......I'll try both ways on my swampy for a proof is in the pudding response.
Without having profound electrical knowledge. a motorcycle battery and a 10 to 20 watt solar panel should do the trick. there is a nice price point on 50 watt solar panels and they are a convenient size. so why not.You can get the numbers you need off your two "appliances" your fan and your pump and match that too your panel/ batts. I'll post my numbers. Please correct me if I'm wrong with your best nice folks, but you can not really oversize your battery, you just need enough electricity from your panel to charge what your swampy and??? are drawing factoring in for losses. I have a feeling there is a balance here to be achieved: too much water pumping over the wick: not enough evaporation. too many cfms of air could be too much evaporation of just defuse the nominal cooling?????? to powerful a fan in a small tent or hexayurt might be uncomfortable.....noise from a fan too small or big yet another consideration.Was going to use a 4 inch inline fan and may in the future with a fan muffler.EUREKA! for more efficiency why not have a drip swampy with no aquarium pump?there must be a way to get optimum drip and and have but a bit of water to pour up higher when not evaporated, or even to have flow stop w/o power. Ay yi yi, I'll post if achieved.On amazon and else where there are solar submersible pumps that come with a 5-10 watt panel, it may be that that would run the fan too and if you just want a daytime solution you could skip the battery "bank" perhaps. there are some decent battery operated fans that also will run off 12 volt. one could mount one of these and use rechargeables. A nice jumper pack in conjunction with a solar panel is a great way to go. This is how I run my ARB fridge freezer which draws far more than a small DIY swamper. Also ideally if you are "boondocking": you want you place of rest in the shade and your panel in the sun, so you want long leads of the correct gauge or other portability.
I tried to reply to specific comments below, the one about adding ice for my latest comment.and the one about how big a solar panel for the latter comment. Instructables wasnt working right, I'll try and move them later: Be cool! Ha.
