How Long Will 400 Watt Solar Panel Run Freezer

Battery capacity in watt hours x 2 rated panel power in watts example.

How long will 400 watt solar panel run freezer.

Environmental factors will likely increase charge time. Lastly you will need the solar panels to keep the battery charged. 3 minutes one important metric to consider when comparing solar panel options is a panel s power rating referred to as wattage. A bit of quick math and conversion to kwh will tell us that each solar panel produces about 30 kwh per month.

You multiply the combined wattage of the solar panels by the number of hours sunlight they will. 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. 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. An amp hour is a way of describing a battery s capacity.

When researching just what a 100 watt panel will get you. Always round this off to the higher number. You also need to look up how much solar you get at your latitude. We run a small chest freezer and a refrigerator on our system but it also powers the rest of the house.

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. Well folks those days are long behind us. Typically a battery is rated assuming a 20 hour cycle. It may seem obvious but all of these factors will effect how much power your 100 watt solar panel can bring in.

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. The answer to this question what can you run with a 100 watt solar panel can be a bit tricky. Currently as we speak our self installed rv solar panels are completely running our new refrigerator.

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. For this example if you are using 404 kwh per year that is 1 11 kwh per day. It s eight 150 175 watt panels a charge controller and an inverter along with miscellaneous wires and such.

How did i come up with 300. It denotes how many amperes can be drawn from a battery and for how long. Using the 2400 daily watt hour figure from the above example you would divide the 2400 by 375 and need 6 4 panels.
