What Size Solar Panel Do I Need To Run A Refrigerator

Well folks those days are long behind us.

What size solar panel do i need to run a refrigerator.

If the quality of sunlight in your locality is poor you might need to install more panels to get the minimum wattage required to power your refrigerator. That panel is rated at 100 watts at peak efficiency meaning on a 78 degree cloudless day at solar noon on the equator during the equinox. Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs. The first thing you need to figure out the wattage rating of your refrigerator.

24 hours a day we have refrigerated food and it is damn glorious. Then divide the kw output by your panel s efficiency to get the estimated number of solar panels you ll need for your system. The average refrigerator found in the united states uses approximately 57 kwh per month while the average freezer uses 58 kwh for a combined total of 115 kwh. Calculate the size of your solar system.

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. 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. A solar power setup suitable for refrigerator use requires several devices in addition to solar panels. It would help if you were a little more specific about the power consumption of your appliances but i will suggest the following.

A device called a charge controller will smooth the flow of power from the panels to the battery. A bit of quick math and conversion to kwh will tell us that each solar panel produces about 30 kwh per month. Divide that by 30 kwh per month per solar panel and you get 3 8 solar panels. Currently as we speak our self installed rv solar panels are completely running our new refrigerator.

Batteries are needed to store the power that the refrigerator will use at night or when clouds block the sun. Solar kit to run tv laptop fridge mobile or lights hi and good luck. You would need about 4x 80 watt panels and about 860 ah 12 v battery bank. To figure out how to size your solar system take your daily kwh energy requirement and divide it by your peak sun hours to get the kw output.

Inverter ratings the manufacturer s label on most. I will show you specific examples based on fridge size and solar panel size. Here are a couple panels that would be good options though with varying wattage levels. To find the watts you multiply amps times volts.
