Can A 100 Watt Solar Panel Run A Refrigerator
Offered that there’s a battery, a standard quantity of straight sunshine, and no partial shading, a 100-watt solar panel can certainly run a little (1.6-2.5 cubic feet) 12V car fridge and can potentially run a 4.5 cubic feet mini-fridge.
Nevertheless, larger refrigerators will need more solar power to run without disruption.
For instance, a basic 10 Cu. Feet. RV refrigerator takes in regarding 1000Wh of power each day. If the 100W solar panel is powering the refrigerator with a battery, it’s feasible to run the refrigerator for 8 to 16 hrs each day.
To be 100% specific, you will require 2 approximates:
- The refrigerator’s everyday power usage.
- The power manufacturing of the solar panel in your place.
Just what does it cost? Power does your fridge utilize?
The complying with the table provides you a concept regarding the typical power usage for various fridge dimensions:
- Refrigerator type Fridge Size Daily Power Usage
- 12V Fridge 1.6-2 Cu. feet. 300Wh-400Wh
- Mini-fridge 3-4.5 Cu. feet. 600Wh-800Wh
- RV fridge 7-11 Cu. ft 900Wh-1200Wh
- Full-size fridge 16-25 Cu. feet. 1500Wh-2200Wh
- Everyday power usage of various fridge dimensions.
Nevertheless, you ought to do your personal estimations or dimensions previously producing any type of choice.
Generally, there are 3 methods to identify just what does it cost? Power your refrigerator takes in:
Check out the EnergyGuide tag:
New refrigerators include an EnergyGuide tag that approximates their annual power usage, and just what does it cost?
For instance, the picture listed below programs the EnergyGuide tag of a 20.6 cubic feet fridge:
The tag approximates that this fridge utilizes 653 kWh (kilo-Watt-hours) annually. From this, we can determine its approximated everyday power usage:
- Everyday Power Usage (Wh) = 653 kWh ÷ 365
- Everyday Power Usage (Wh) = 1.789 kWh
- Everyday Power Usage (Wh) = 1789 Wh
For this specific instance, the refrigerator ought to take about 1800 Watt-hours each day, provide or take a 100Wh.
Currently, suppose you do not have this tag?
Utilize the producer’s technological specs:
On the specification sheet of the fridge, I was looking for the power level or the voltage/present.
For instance, the picture listed below programs the spec tag of a 7 cubic feet fridge:
The specification sheet programs 100W as the Ranked Input. This implies that the fridge utilizes 100 watts of power when it is operating.
Nevertheless, in some cases, the power usage is not straight defined on the tag. In various other situations, the producer defines a couple of power inputs (Thawing input, heating unit cable input, etc………..…), which makes it a bit complicated.
To prevent complications, you can utilize the voltage and the present to determine the power level:
- Power (Watts) = Voltage (Volts) x Present (Amps)
- For this instance:
- Power (Watts) = 220 V x 0.45 A
- Power (Watts) = 100W
Still, this is not the power usage of the fridge, and it is the power it utilizes when the compressor is operating.
Nevertheless, we can still utilize the power used to approximate the power usage:
Power (Watt-hours) = Power (Watts) x Use Time (Hours)
We have the power; however, what is the use time?
Generally, the compressor has a responsibility cycle of regarding 0.33 (runs 33% of the moment). This implies that in 24 hr, the fridge is just on for regarding 8 hrs.
- Power (Watt-hours) = Power (Watts) x Use Time (Hours)
- Power (Watt-hours) = 100 Watts x 8 hrs
- Power (Watt-hours) = 800 Wh
To ensure you are not underestimating its power usage, you can increase the power use by 10 or 12 rather than 8.
OR, you can opt for a much more accurate technique.
Utilize a power dimension device:
With devices such as the kill-a-watt or the Kuman meters, you can connect your refrigerator to the wall surface and check its power use over a specific time period.
All you need to do is connect it in, delay it 24 hr, and the check will provide you the power usage in kWh (kilowatt-hours).
Currently, we have to take a look at the real power manufacturing of the 100-watt solar panel to see if it was most likely to suffice.
Just what does it cost? Power will you receive from a 100W solar panel?
Since the power manufacturing of a photovoltaic panel varies about how remove the skies is or just what does it cost? Straight sunshine it’s getting, one of the most accurate methods to determine its everyday power manufacturing is to utilize an electrical power metering gadget.
Nevertheless, thank you to the information gathered by the Nationwide Sustainable Power Lab (NREL), anybody can approximate the quantity of everyday power that their solar system ought to create.
For instance, a place that gets a standard 5kWh/m2 of sunshine each day can be stated to get 5 top sunlight hrs. You can, after that, approximate just what does it cost? Power a 100-watt solar would certainly create in this place:
- Power Manufacturing (Watt-hours each day) = Solar Panel Power level (Watts) x Top Sunlight Hrs (Hours)
- Power Manufacturing (Watt-hours each day) = 100 W x 5 hrs
- Power Manufacturing (Watt-hours each day) = 500 Wh/day
This implies that in this place, the solar panel would certainly create about 500 Wh of power each day. This suffices to run a 12-volt car fridge and even a small refrigerator.

So, the number of top sunlight hrs do you obtain?
To inspect your top sunlight hrs, click on this link and send your deal. will a 100 w solar panel run a fridge After that, most likely to outcomes.
Will a 100 w solar panel run a fridge?
Based on your place, the device provides you not just the annual typical but likewise the regular month-to-month typical top sunlight hrs, which is quite helpful.
For instance, for the place that I utilized the device, a 100-watt panel would certainly typically obtain 5.45 top sunlight hrs. Its typical everyday power manufacturing can be determined because of this:
- Power Manufacturing (Watt-hours each day) = 100 W x 5.45 hrs
- Power Manufacturing (Watt-hours each day) = 545 Wh/day
- You can likewise approximate the power manufacturing of the solar panel for a specific month.
- For instance, for this place, this is the everyday power manufacturing that ought to be anticipated in the month of July:
- Power Manufacturing (Watt-hours each day) = 100 W x 6.64 hrs
- Power Manufacturing (Watt-hours each day) = 664 Wh/day
Since you have a quote of just what does it cost? Power, a 100-watt solar panel, would certainly create in your place; contrast it to the power usage of your fridge.
In a situation it’s not sufficient, the following area discusses how you can determine the correct amount of solar power that’s required.
Just what does it cost? Solar power, do I have to run a fridge?
To determine the quantity of solar power you have to run your fridge, split the refrigerator’s approximated everyday power usage by the variety of top sunlight hrs in your place:
Solar power required (Watts) = Approximated Everyday Power Usage (Wh) ÷ Top Sunlight Hrs (hours)
Let’s think about a 20 cubic feet fridge that – typically – takes in 2000 Wh of power each day. And let’s state that the proprietor of this refrigerator resides in Tuscon, Arizona.
I utilized the PVWatts device to inspect the quantity of sunshine that this place gets, and it appears that typically, the place obtains 6.54 Top Sunlight Hrs (gets 6.54kWh/m2 of sunshine each day).
