Today I bought 100W solar panel from Canadian Tire. The panel kit was discounted $350, so seemed like a good deal. The plan is to hook it up to a battery/3000W inverter system. Allowing me to run pumps and other darkroom trailer appliances.
I want to be able to run an agitation, washer, pump type set up in the trailer to wash plates for long periods of time in the field. I am trying to use Sodium Thiosulfate instead of KCN (Potassium Cyanide) as a fixing agent. Sodium Thiosulfate (Hypo) requires much longer wash times. I will need power to run a pump which allows for agitation in the wash trays.
Hope this works!
