Currently as we speak our self installed rv solar panels are completely running our new refrigerator. Well folks those days are long behind us. How many solar panels do i need to power my television. 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.

Divide that by 30 kwh per month per solar panel and you get 3 8 solar panels. I will show you specific examples based on fridge size and solar panel size. Batteries are needed to store the power that the refrigerator will use at night or when clouds block the sun. Remember back when we decided to rip out our rv refrigerator because it kicked the bucket and lived out of a cooler for a year.

Newpowa 175w solar panel 58 x 26 inches. The average refrigerator use varies from as low as 200 watts for a new energy star refrigerator to as high as 600 watts for an older unit.

To run this refrigerator you will need an inverter that can handle 600 watts for long periods and a surge of 1 800 watts for a split second. At startup your refrigerator may have a higher draw so you want to err on the high side when you figure how many watts of power you need. You can do this by finding the amps and the volts on the electrical label on the device. A solar power setup suitable for refrigerator use requires several devices in addition to solar panels.

To find the watts you multiply amps times volts.
