How Long Will 400 Watt Solar Panel Run Freezer

When researching just what a 100 watt panel will get you.

How long will 400 watt solar panel run freezer.

The answer to this question what can you run with a 100 watt solar panel can be a bit tricky. It denotes how many amperes can be drawn from a battery and for how long. Divide that by 30 kwh per month per solar panel and you get 3 8 solar panels. 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.

A bit of quick math and conversion to kwh will tell us that each solar panel produces about 30 kwh per month. For this example if you are using 404 kwh per year that is 1 11 kwh per day. 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.

You multiply the combined wattage of the solar panels by the number of hours sunlight they will. It s eight 150 175 watt panels a charge controller and an inverter along with miscellaneous wires and such. A typical solar battery provides 12 volts of electrical energy for a certain amount of amp hours. Typically a battery is rated assuming a 20 hour cycle.

Always round this off to the higher number. How did i come up with 300. Now divide the daily watt hours by the wattage produced by one solar panel. You also need to look up how much solar you get at your latitude.

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. Currently as we speak our self installed rv solar panels are completely running our new refrigerator. If you have a 75 watt panel and 5 hours of sun per day you would produce 375 watts per day per panel. It may seem obvious but all of these factors will effect how much power your 100 watt solar panel can bring in.

Environmental factors will likely increase charge time. An amp hour is a way of describing a battery s capacity. Using the 2400 daily watt hour figure from the above example you would divide the 2400 by 375 and need 6 4 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.

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