# How Many Solar Panels To Power A Refrigerator

## Solar Panels Reaction On Cloudy Days

Solar Powered Freezer Fridge Conversion Updates Use Only 300 WH Per Day

Solar panels react to the visible spectrum of light.

In other words, with enough visible sunlight, solar panels can start generating electricity.

But the stronger the sunlight, the better is the reaction of solar panels to temperature.

During summer, many solar panels produce more electricity, indicating a need for warmer working times.

However, thats not always the case.

Remember that stronger sunlight and warmer temperatures often go hand in hand.

In fact, if the temperature gets too hot or too cold, many solar panels become less efficient.

## Calculating The Refrigerator Watts

You first need to understand how much power your refrigerator requires to work. For that, you have to determine the wattage rating of the device, which will need its amps and volts. Check the product details or the labels to find this information.

After that, you have to multiply both values, i.e., Amps x Volts= Wattage Rating. Thats a good start!

The value will give you the approximate watts needed to run your fridge. Sometimes, these devices might need more power to get started than to run.

Find out the starting wattage of your refrigerator by multiplying the value you figured out above with 1.5. So, Amps x Volts X 1.5= Starting Wattage.

## Determining The Power Consumption Of Solar Freezers And Refrigerators

Your freezers nameplate rating label will most likely feature the power consumption details. You can check the body of the refrigerator for this label, which mentions the voltage and current requirements of the device. Multiply the two values, and this will give you the required number of watts.

For instance, if your refrigerator mentions 4.5 amps of current and 120 volts, your requirement for the solar power appliance in watts would be 540.

## What Else Do I Need

If you thought calculating your solar energy requirements was hard, you are not out of the water yet. Another difficult part of powering your refrigerator with solar panels is getting everything that is needed.

Unfortunately, you cannot hook up your fridge to solar panels and expect it to work. On the contrary, the panels need several items, including a solar battery, power inverter, and charge controller.

## Battery Size For Solar

Around 1400 watt-hours of power can be stored in a medium-sized battery. Since it is recommended that you keep your batteries at least half full at all times, you have around 720 watt-hours of power that is usable.

Ensure that you pick a battery with high capacity because the sun might not shine every day.

Note: If you wish to run your solar freezer for 4 days, and the device takes up 840 watts a day, you need to generate and store around 3400 watts at least.

Running an AC unit off-grid with solar panels is not a cost-effective proposition. As much as 3kW of solar panels is need for an average air conditioner.

It is viable if whole-house grid-tie solar is installed. In this way the grid can supplement the power needs and the solar power can run the rest of the appliances during the months when AC is not needed.

## All You Need To Know About Running A Freezer On Solar Power

Solar power is becoming increasingly popular among Indians, especially as a way to power household appliances, such as freezers, which use up a lot of electricity. However, you need to be aware of how to set up the right solar power system if you want renewable energy running your freezer.

If you have an on-grid solar system, and you have wondered how much solar power I need to run a refrigerator, you would be pleased to know that you can operate a freezer in a straightforward manner. You just need to contact a provider of solar panels and have them install the same at your home.

But, if you are reliant on an off-grid solar system that you installed yourself, you need to consider these crucial factors in order to ensure that your freezer remains functional even during cloudy days.

## How Much Power Does Your Refrigerator Need From The Solar Panels

When using a solar panel to power a refrigerator, you must consider the wattage the solar panels can deliver and the amount the fridge would need per day.

That means itd be best to start by determining the proper wattage for your appliance by looking at its label. Typically, the latest models come with an Energy Star Rating sticker on the door or the side. Here, you can estimate how much the fridge will consume annually, given as kWh/year.

You can get the daily consumption by dividing the consumption rate by days in a year, roughly 365 days. Remember that the Energy Star ratings account for times when the fridge will be on energy saver mode.

Assuming your refrigerator consumes 365 kWh per year, its daily consumption would be

365 kWh / 365 days = 1 kWh per day

If the information is not available, you can find the wattage by multiplying the amps by volts. You can get the two values on a tag or sticker at its back. The answer you get will be in watts.

Divide it by 1000 to convert it to kilowatts and then multiply it by the average hours you use the refrigerator per day to get its daily consumption is kWh/day.

Suppose the power rating isnt available anywhere on the refrigerator and check the manual. If still not available, check at the manufacturers website or google the model number. If nothing is available, search for similar refrigerators online and use their ratings for the estimates.

120 volts x 5 amps = 600 watts

600 watts / 1000 = 0.6 kilowatts

## How Much Solar Power Do I Need To Run A Refrigerator

Undoubtedly, a fridge is an essential appliance most homeowners cant live without. In general, youll need four regular solar panels to run a fridge.

On average, full-size refrigerators consume between 1500Wh and 2000Wh of energy per day. To run a refrigerator completely on solar power, you would need 300 to 400 watts of solar power.

The exact amount of solar power you need depends mainly on the power consumption of your refrigerator, and on your location.

However, its a tiny bit more complicated than that.

To run a refrigerator on solar power, you need a solar system that consists of:

• Solar panels
• A battery bank: To store energy during the day and use it at night or when sunlight is scarce.
• A solar charge controller: To maximize power production and protect the solar panels and the battery.
• An inverter: To convert low voltage DC power into higher voltage AC power that the refrigerator can use.

In this article, Ill show you a few easy and simple steps you can take to:

• Efficiently determine how much solar power you need to run your refrigerator.
• Correctly size the components of the solar energy system.

## Number Of Solar Panels Required For The Mains Fridge / Freezer

We have already calculated the power consumption and how big the batteries need to be so we know that after 4 days of little sunshine 3600 Watt hours of power need to be put back into the batteries. A 100 Watt solar panel will produce about 75 Watts in good conditions. If the panel is in full sunshine for 5 hours it will produce 5 Hours x 75 Watts = 375 Watt hours of power. So thats 10 solar panels? Well no not quite because some of the time the sunshine will be running the fridge as well as charging the batteries. So probably 6-8 will suffice. Thats still a considerable number of solar panels just to run a fridge freezer

Now, lets come to the main thing. Portable Solar panels or any solar panel for that matter cannot work without direct sunlight hitting them in order for them to generate solar energy in return. This clearly paves the path for activating your refrigerator strictly during the hours in the daytime.

So, what about the nights? To have the luxury to power your refrigerator during the night, you have to install a solar battery to store the solar energy during the day and release it during the night to keep your refrigerator running.

Therefore, before hurrying to the store to buy a solar battery, you must remember that your battery capacity should be able to handle the kind of power required to run your refrigerator for the whole night.

• There are batteries available with different voltages, such as 12v, 24v, and 48v, suitable for different appliances. To run a refrigerator, a 12v battery will be the best option.
• Next, you must measure the amp-hours of the battery, which indicates its capacity and how many amperes it may provide to your refrigerator.
• If suppose, the running watts of the refrigerator is around 200 watts, the total of watts per day can be calculated by multiplying 200 watts within 24 hours. Thus, youll get the result as 4.8 kWh .
• Thus, you can figure out the total amperes by this formula: 4800Wh ÷ 12V = 400Ah.

## Trading Polluted Energy For Clean Energy: The Importance Of Solar

To begin this discussion on solar panels, it would be unfair not to note that they can be quite expensive to purchase. Even so, a lot of people have purchased them to place on top of their homes. They feel the amount of money they save on their electric bills besides putting their fair share into saving the environment is worth a one-time cost to buy and install the panels.

In that way, that answers the question of how it could help you and the planet. But let us not be blind and think that all can afford such a project no matter the savings it will add to your wallet. In other words, there may be limitations working up to your goal of a total energy source for everything in or around your home.

Find out the amount of power the refrigerator needs and multiply it with the number of hours you intend to use it. Divide the first number by the second number, and youll have the solar panels you need.

Its that simple. However, there is a lot of factors involved. Itd be best to understand them before you start the calculations. This post simplifies things for you.

## How Many Solar Panels Do I Need To Run A Refrigerator

A fridge uses a lot of energy, but not too much to run on solar. Running a refrigerator on solar panels may seem like a difficult and impossible task, but its a common misconception that is going to be addressed in this post.

With an average ENERGY STAR rated refrigerator, it will take 2-3 solar panels to power. This is taking into account a 300W rated panel and an average 15-amp, 120V refrigerator.

For this post, its focused on a refrigerator that is average in a home. It isnt a small portable fridge, but not a massive 27 cu. ft. commercial refrigerator either.

First step: finding the correct information to answer the question of how many solar panels you need is crucial to ensuring power needs are met.

Here are three ways to find out the power rating for the fridge you want to power with solar panels.

• Go to the manufacturers website. Even if it isnt the manufacturers website, you can usually still find this information on store websites like Best Buy. Look for technical specifications.
• Look inside the door of the refrigerator an image of mine is below. This will show information like how many volts, amps, and even the wattage of the defrost heater or ice maker.
• Find the EnergyGuide label to understand usage for your refrigerator appliance. This has an estimated annual electricity use and cost.

## Youve Heard Of Gas Guzzlers Cars That Burn Your Wallet With How Fast They Burn The Fuel You Put Into Them

And just like on the road, youve got a few energy guzzlers at home too, appliances that take a lot of electricity to run. And if you are planning on making the switch to renewable energy and installing solar panels in your property, youll want to know the culprits.

And if you already are running solar energy, you want to keep track of where that power is going.

Refrigerators

One of the higher energy guzzlers is a much necessary member of any household, the refrigerator.

According to different studies, the average refrigerator takes about three or four average solar panels to run.

However, there are a lot of factors to consider.

Two homes with the same number and type of appliances may use power in a completely different way, just given by the living habits of the people living in them.

Say for instance, no ones home for much of the day theyre either at work or school.

Or, on the other hand, you work from home part-time and head to the offices only once or twice a week.

Energy consumption will be very different from that of your neighbor.

It also depends on how much food you keep in your refrigerator, its age and how long you leave it open.

Now lets crunch some numbers.

A good, efficient average solar panel generates about 30 kWh in an average month. An average refrigerator uses an estimated 57 kWh the freezer about 58 kWh every 30 days. If you divide those, it will give you an average of 3.83 solar panels.
