How Many Watts Solar Panel To Run Refrigerator

Newpowa 175w solar panel 58 x 26 inches.

How many watts solar panel to run refrigerator. 115 x 4 5 517 5 watts of power. For most residential homes 200 will be more than enough with 180 watts being enough for fairly large fridges. For example a fridge may read 115 volts and 4 5 amps of current. A fridge freezer will of course require a bit more energy with a 240 liter combo requiring closer to 300 400.

Divide that by 365 to get 1 11kwh per day. As you can see the average fridge power consumption is usually anywhere between 100 400 watts. Below is an example of the energy guide label you can find with your annual kwh usage. Divide by 24 and multiply by 1 000 to get the watts.

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. We were completely able to run our fridge 24 hours a day at a very cold setting. So this fridge runs on about 46 running watts. The refrigerator is rated at 8 5 amps x 115 volts 977 5 watts.

Multiply these two quantities to calculate its power demand. The inverter dipped from 13 8 normal full battery charge to only 12 6 while the fridge it on. Here are a couple panels that would be good options though with varying wattage levels. 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.
