How Long Will 400 Watt Solar Panel Run Freezer

Always round this off to the higher number.

How long will 400 watt solar panel run freezer.

Lastly you will need the solar panels to keep the battery charged. Environmental factors will likely increase charge time. 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. When researching just what a 100 watt panel will get you.

Currently as we speak our self installed rv solar panels are completely running our new refrigerator. For this example if you are using 404 kwh per year that is 1 11 kwh per day. 24 hours a day we have refrigerated food and it is damn glorious. It s eight 150 175 watt panels a charge controller and an inverter along with miscellaneous wires and such.

Well folks those days are long behind us. It denotes how many amperes can be drawn from a battery and for how long. 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. 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. How did i come up with 300. You also need to look up how much solar you get at your latitude. Divide that by 30 kwh per month per solar panel and you get 3 8 solar panels.

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 may seem obvious but all of these factors will effect how much power your 100 watt solar panel can bring in. We run a small chest freezer and a refrigerator on our system but it also powers the rest of the house. 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. The answer to this question what can you run with a 100 watt solar panel can be a bit tricky. A typical solar battery provides 12 volts of electrical energy for a certain amount of amp hours.

Using the 2400 daily watt hour figure from the above example you would divide the 2400 by 375 and need 6 4 panels. A bit of quick math and conversion to kwh will tell us that each solar panel produces about 30 kwh per month. 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.
