In this article I will explain how to calculate how many solar panels I need to power a refrigerator. It is common knowledge that refrigerators need a lot of energy to operate. But really how many solar panels do I need to power a refrigerator .
Do you want to configure your solar power system but are not sure what size configuration you need? This blog is designed to give you the tools to find out exactly what you are pulling from your equipment batteries and what type of solar insulation you need.
How many solar panels do I need to power a refrigerator
Knowledge is key when configuring your equipment for solar installation and that it can power a refrigerator without problem, so the more information you have about each of the home comfort devices that you plan to take, the better.
But if your house has solar panels, an alternative is a solar panel refrigerator .
Make no mistake, don’t think it is a refrigerator “made” especially to run on solar energy.
It is a common refrigerator that we will use solar panels to generate the electricity it consumes. Clarified this we continue
Let’s start looking at how many solar panels I need to run a refrigerator. Let’s start with your refrigerator. The average refrigerator needs about three or four average solar panels to run, but that number could be as low as one or quite a bit higher. But why?
How many solar panels do I need: There are more variables than you might expect
Two households with identical appliances can use energy completely differently due to the living habits of the residents.
If you go to work early and don’t come home late and spend weekends traveling, you’re going to use less energy than someone who is home all the time.
How many solar panels do I need for a refrigerator ? When it comes to your refrigerator, your energy consumption depends on how much food you have, or how old the appliance is and how long you leave it open. These variables could have a big impact either way.
You will also have to take into account where you live to determine how much sun you get. It should come as no surprise that the same solar panel can generate much more or less energy depending on the area where it is installed.
Solar panel for refrigerator: How many solar panels do I need for a refrigerator?
Solar powered cooler
A single solar refrigerator panel can also produce a variable level of electricity throughout the day.
This is because the optimal conditions for the maximum performance of the solar panel do not occur throughout the day, at certain times of the day the solar panel produces more electricity than others.
This depends on the insolation that the solar panel receives, it may be that at some point of the day the sky is cloudy.
How many watts does a solar panel produce?
However, as a very broad average, a highly efficient solar panel produces around 265 watts.
A little quick math and the conversion to kWh will tell us that each solar panel produces approximately 30 kWh per month.
The average refrigerator uses approximately 57 kWh per month, while the average freezer uses 58 kWh, for a combined total of 115 kWh.
Divide that by 30 kWh per month per solar panel and you get 3.8 solar panels.
Solar panel to power a refrigerator
Keep in mind that to know exactly how many solar panels I need for a refrigerator, it will depend on the power of the solar panel, the efficiency and the brand.
A solar panel refrigerator can be the solution to reduce the energy consumption of your house and thus lower the cost of your energy bill.
Let’s look at some other examples.
How many solar panels do I need for a TV?
A 60 ‘TV uses 29 kWh while your computer uses 21 kWh. Your DVR or Cable Box uses 23 kWh. Count to at least one panel and possibly two.
How many solar panels do I need to run my washer and dryer?
It will cost you about 6 kWh to run your washing machine and 57 kWh to run your dryer. Then you will need three solar panels just to keep your clothes clean.
How many solar panels do I need to power my air conditioner?
Central air conditioners are huge energetic pigs. They use about 3,5000 watts, or 3.5 kWh, for every hour they are running.
That means each solar panel will be able to power your A / C for just 8.5 hours. If you run your A / C for 4 hours per day, that means you would need more than 14 solar panels to cover 120 hours per month of use.
Your devices use more energy than you can realize
It’s amazing how much energy the average home uses. Please note that our estimates assume that all your devices are working all the time; this is not the case, so you will “need” fewer panels.
Fluctuations in energy use
A refrigerator uses energy in different ways depending on its operating conditions.
If there are a number of cold items inside or if the room temperature is good, it will stay cold longer.
Therefore, it will not need to be turned on as often. When the air compressor in the refrigerator is started, it needs a power boost that can use three times the normal operating current. This surge occurs only for a fraction of a second.
After start-up, the refrigerator uses power according to the voltage and current on the nameplate.
Batteries and Inverter
A typical solar battery provides 12 volts of electrical power for a certain number of amp-hours.
An amp-hour is a way of describing the capacity of a battery; denotes how many amps can be drawn from a battery and for how long.
Generally, a battery is rated assuming a 20 hour cycle. For example, a 160 amp-hour battery would theoretically provide 8 amp-hours for 20 hours.
Most solar batteries will provide enough current for the refrigerator and other appliances.
Inverters, which are required to convert battery power from DC to the AC current used by most devices, are never 100 percent efficient, and up to 50 percent of power can be lost in conversion .
Look for an inverter with a high efficiency rating and be sure to factor in the inefficiency of the inverter when calculating your refrigerator’s power needs.
They can take a look at your past energy bills and work with you to create a system that meets your needs and fits your budget.
Maybe you have an air conditioner and you know that these devices consume a lot of electricity right? So I invite you to read the article on solar air conditioning , I could give you an idea of what you can save with solar panels
