How Long Will 400 Watt Solar Panel Run Freezer

It denotes how many amperes can be drawn from a battery and for how long.

How long will 400 watt solar panel run freezer. Well folks those days are long behind us. 3 minutes one important metric to consider when comparing solar panel options is a panel s power rating referred to as wattage. It s eight 150 175 watt panels a charge controller and an inverter along with miscellaneous wires and such. So you are going to need a total wattage of 300 combined 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. Always round this off to the higher number. 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.

Now divide the daily watt hours by the wattage produced by one solar panel. Currently as we speak our self installed rv solar panels are completely running our new refrigerator. A bit of quick math and conversion to kwh will tell us that each solar panel produces about 30 kwh per month. Lastly you will need the solar panels to keep the battery charged.

For this example if you are using 404 kwh per year that is 1 11 kwh per day. Divide that by 30 kwh per month per solar panel and you get 3 8 solar panels. When researching just what a 100 watt panel will get you. 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. 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. The answer to this question what can you run with a 100 watt solar panel can be a bit tricky.

Using the 2400 daily watt hour figure from the above example you would divide the 2400 by 375 and need 6 4 panels. You multiply the combined wattage of the solar panels by the number of hours sunlight they will. How did i come up with 300. 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.

Environmental factors will likely increase charge time. It may seem obvious but all of these factors will effect how much power your 100 watt solar panel can bring in. If you have a 75 watt panel and 5 hours of sun per day you would produce 375 watts per day per panel.
