How many watts solar panel to run refrigerator.

For example a fridge may read 115 volts and 4 5 amps of current. Here are a couple panels that would be good options though with varying wattage levels. We were able to turn off the fridge with the click of a button to use other things. The nameplate ratings list the appliance s voltage and current demands.

A typical assumption for a residential refrigerator is that the compressor motor will run 1 3 of the time this is assuming it is operating in an ambient temperature of 70 degrees 978 watts x 24 hours day x 1 3 operational time 7824 watt hrs day. Divide by 24 and multiply by 1 000 to get the watts. We were completely able to run our fridge 24 hours a day at a very cold setting. A fridge freezer will of course require a bit more energy with a 240 liter combo requiring closer to 300 400.

The inverter dipped from 13 8 normal full battery charge to only 12 6 while the fridge it on. Divide that by 365 to get 1 11kwh per day. The short answer if we assume a 5 5 x 3 foot solar panel 200 to 250 watts would generate about 0 75 kwh per day it would take three of those panels to power a fridge that uses 46 wkh per month. 115 x 4 5 517 5 watts of power.

Newpowa 175w solar panel 58 x 26 inches. For most residential homes 200 will be more than enough with 180 watts being enough for fairly large fridges. Multiply these two quantities to calculate its power demand. So this fridge runs on about 46 running watts.
