How Many Solar Panels To Run Minifridge

The panel estimation seems very accurate.

How many solar panels to run minifridge. Lower wattage models can range between 85 to around 100 watts while running 4 but many mini fridges can go up to 250 watts 5 here are some tips for keeping your mini fridge s compressor from turning on too often and boosting the starting wattage. Roughly our fridge draws 1 3 amps per hour. Which when you consider the solar setup draws about 5 amps per hour total we have a decent amount of amps per hour leftover to do with what we please. Wattage use for a mini fridge can be found with the same formula.

The beginning stages of research with solar power is always how much power with how many panels. Very timely thank you. Lastly you will need the solar panels to keep the battery charged. This off grid system has been working great since may 2013.

Typically a battery is rated assuming a 20 hour cycle. The fridge will draw about 60 80 watts but not run all the time as it reaches temp if you only open it 4 to 6 times a day quickly it won t run as much probably only run about 4 or 5 hours a day. And it is really great that you re thinking of using solar. The answer to this question what can you run with a 100 watt solar panel can be a bit tricky.

If we assume the panel gets about four hours of direct sunlight per day again plenty of variance here that s 1000 watts or 1 kwh of power in one day. The 160 watt panel with 3 good hours of sunlight which is about average will get you 480 watts to use daily if the fridge runs 5 hours at 80 watts. How did i come up with 300. An amp hour is a way of describing a battery s capacity.

So we used a whole bunch of confusing math and figured everything out. It s definitely a smart way to go. A bit of quick math and conversion to kwh will tell us that each solar panel produces about 30 kwh per month. We set up the solar panels which we procured from windy nation.

So you are going to need a total wattage of 300 combined solar panels. Thus a total of 30 kwh per month with one panel. For example we consume about 1500 kwh per month which averages out to about 50 kwh per day or 50 000 watt hours per day. A typical solar battery provides 12 volts of electrical energy for a certain amount of amp hours.

We are in the process of specifying a solar system for our ranch. Here is an after the fact implementation of how i power my refrigerator from the sun. 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.

The solar panel math. While there are a lot of variables to consider a 5 5 x 3 foot solar panel can produce roughly 250 watts of electricity.
