What is comparable sizing for powering an electric refrigeration AWG unit using PV (Photo Voltaic solar panels)?
These numbers are only for comparison purposes. Our nearest competitor is a electric refrigeration AWG powered by a Photo Voltaic system or a diesel generator. These are quick calculations based on statistics published for a Electric Refrigeration AWG unit sold out of Europe. Please confirm these with your solar design engineer. We used this particular electric refrigeration AWG unit because one of our customer prospects contacted us after they purchased the electric unit and still needed a better solution. The electric refrigeration AWG unit is rated at 24 liters (6.3) gallons per day with a maximum power usage of 650 watts. Most of the electric units are rated for 24 hour production so I used an assumption of 1 liter per hour. Using their max power rating this came to a total of 15,600 Watt hours. Assuming the batteries charge at 75% efficiency and the inverter used is 90% efficient this would require (15,600 / 0.75) / 0.90) = 23,111 Watt hours. Assuming a 9 hour productive solar day
