How Long Will 400 Watt Solar Panel Run Freezer

Environmental factors will likely increase charge time.

How long will 400 watt solar panel run freezer.

An amp hour is a way of describing a battery s capacity. You multiply the combined wattage of the solar panels by the number of hours sunlight they will. If you have a 75 watt panel and 5 hours of sun per day you would produce 375 watts per day per panel. The answer to this question what can you run with a 100 watt solar panel can be a bit tricky.

When researching just what a 100 watt panel will get you. It may seem obvious but all of these factors will effect how much power your 100 watt solar panel can bring in. 400 watt w solar panels are above the average wattage of solar panels available today and can be a solid panel option for many types of solar projects. Lastly you will need the solar panels to keep the battery charged.

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. Battery capacity in watt hours x 2 rated panel power in watts example. Divide that by 30 kwh per month per solar panel and you get 3 8 solar panels. How did i come up with 300.

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. Always round this off to the higher number. We run a small chest freezer and a refrigerator on our system but it also powers the rest of the house. A bit of quick math and conversion to kwh will tell us that each solar panel produces about 30 kwh per month.

Well folks those days are long behind us. 24 hours a day we have refrigerated food and it is damn glorious. 3 minutes one important metric to consider when comparing solar panel options is a panel s power rating referred to as wattage. Now divide the daily watt hours by the wattage produced by one solar panel.

Typically a battery is rated assuming a 20 hour cycle. Currently as we speak our self installed rv solar panels are completely running our new refrigerator. 10 watt 18 volt solar panel charging a 12v 10 amp hour lead acid battery 120 wh from 50 full to full time 60wh x 2 10 watts 12 hours. It s eight 150 175 watt panels a charge controller and an inverter along with miscellaneous wires and such.

You also need to look up how much solar you get at your latitude. A typical solar battery provides 12 volts of electrical energy for a certain amount of amp hours. So you are going to need a total wattage of 300 combined solar panels.
