Product review (4 stars): No more propane headaches !  Thanks Eco Solar Cool
Well after much pondering on what kind of solar fridge to purchase I finally settled on the 6.2 cuft eco solar cool model with a little persuasion from the sales rep. I wasn't sure what to expect because I had not heard of this brand before and there seemed to be little info on power requirements.etc.
I have been running this top fridge bottom freezer now for 3 weeks with a 6 amp 12 volt converter by sun force with no problems. Freezer at-15'C and  fridge at a comfy 4'C. My kill a watt meter says it is using 300 watts per  24 hr. day at +22'C..not bad at all for a reasonably sized fridge/freezer combo in my opinion. That is 177 watts less than sundanzers dcrf134 upright and its 1.7 cuft larger than the sundanzer.
So this would equate to approx needing  160w of solar panels, 324 amp hours of 12 volt battery power( this gives you 4 days power with no sun) and 6 hours of sun per day for charging, and that should get you through those +32'C days. Or at an ambiant temp of 21'C you need a 95 watt panel and 194 Ahr battery and 6 hrs sun time a day. Oh you will also need a battery solar charge controller so you don't over or under charge your battery.(about $60)
If you find the above options above too expensive you could get by with a smaller panel and lower amp hr batteries if you are just a weekend warrior, or keep the ambient air around your fridge at 21'C or lower.  I hooked up a 12v car battery to  test run it and it ran 24 hrs at 20'C. This fridge is destined to my non air conditioned camp. Jim at eco solar cool was great
tell him bloopy1 sent you if you purchase. My overall impressions are ; lots of freezer space,and equal fridge space. Nice interior. Fridge light but no freezer light. 2 year warranty. Charge controller not included. Exterior finish so so.
Runs nice and quiet, does the job.  Thanks for reading my review.
