How Big Solar Panel For Fridge

Currently as we speak our self installed rv solar panels are completely running our new refrigerator.

How big solar panel for fridge.

To start it s an upright fridge freezer combo designed to run off of 24v dc power and provides a total of 10 3 cubic feet of storage space with adjustable temperature levels. 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. When it comes to solar refrigerators the unique ugp290l1dcb is in a league of its own. If you have an inverter it will need to handle about twice as much as the maximum load so a 2 200w inverter should work for this example.

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. 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. Ideally an inverter refrigerator is the best bet but my old refrigerator needs 300watts when on. The solar panels will charge the battery and keep it ready to supply power to your fridge.

Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs. The flow of electricity will vary depending on the amount of sun on our solar panel or if the battery is full or empty large or small. The solar panels have to be connected to a battery and inverter to provide power to your fridge. 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.

Seriously i can t get over how much i love this refrigerator. Divide that by 30 kwh per month per solar panel and you get 3 8 solar panels. 24 hours a day we have refrigerated food and it is damn glorious. Well folks those days are long behind us.

Basically any fridge will do but the more energy efficient means a smaller solar setup is needed. That s downright roomy for solar fridges and plenty of space. A solar power setup suitable for refrigerator use requires several devices in addition to solar panels. Amp hour ah the steady flow of 1 amp for one hour 5 amp hour 5ah is a flow of 5 amps for one hour or 1 amp for 5 hours.

Here are a couple panels that would be good options though with varying wattage levels. A device called a charge controller will smooth the flow of power from the panels to the battery.
