In many homes, there is usually a TV, but for different homes, TVs run for different times of the day and they will require different amounts of power consumption. Although TVs don’t consume as much power as high-powered electronic devices such as air conditioners or washing machines, after a day’s use, the TV’s power consumption accounts for a non-negligible portion of a home’s energy use, so it’s important to know how much power a TV consumes.
1. How much power does a TV consume?
On average, a TV uses between 40W and 300W of power, but this will depend on other factors such as the type and size of TV you are using. It also depends on other factors such as the type of TV you are using, its size, etc. And the newness of the TV will also affect the power consumption of the TV. A new TV will consume less power than an old one, because the newer one is more efficient in terms of electricity consumption, as compared to an old one, when they are used for the same amount of time and in the same playback mode.
For the above mentioned influencing factors, it is the length of time the TV is running that has the biggest impact on the power consumption of the TV. But when we take into account these factors that will affect the power consumption of the TV, our estimate of the power consumption of the TV in a day, for most families, the difference between them will be larger. This is especially true for families with small children, so the TV power consumption of such families will be higher. Below we will calculate for you in detail the power consumption of your TV in a day.
Power of the TV: Before calculating the power of your TV, you need to know how much power your TV has, which you can find directly in the manual of your TV. You can also refer to the table below.
| TV size (inches) | Type of TV | Average power (watts) |
| 18 | LED OLED QLED | 40~80 50~100 40~90 |
| 21 | LED OLED QLED | 80~120 100~150 90~140 |
| 32 | LED OLED QLED | 120~150 150~200 140~180 |
| 42 | LED OLED QLED | 150~200 200~250 180~220 |
Record the amount of time spent watching TV in a day: In recent years, the average time spent watching TV has been decreasing, and the number of people watching TV has been more limited, so the amount of time spent on TV per day is about 4h to 6h. However, the exact amount of time that the TV is being used in your home still needs to be recorded by you.
Once you know the above two data, you can calculate the power consumption of the TV in a day according to the following formula.
TV power consumption in a day = TV power * daily usage time.
If the power of your TV is 100W, and the TV will play 5h in a day, then the power consumption of your TV in a day will be 100W*5h=500W, which is 0.5kwh. However, the result of this calculation is not very accurate, and it is only an approximate understanding of the power consumption of your TV. If you want to know more accurate power consumption, you can calculate it according to the unit of one month or one year.
2. How much can I save by using a solar system to power my TV?
The amount of money you can save by using a solar power system to power your TV is not only related to the power consumption of the batteries, but also closely related to the price of electricity in your area. The higher the price of electricity in your area, the more money you can save. Although you may save less money in a day for a device that does not consume a lot of electricity such as a TV, in the long run, using a solar system can still save you some of the money you spend on electricity. You can use the following formula to roughly calculate the amount of money you can save.
Savings = TV Consumption * Local Electricity Price
If your local electricity price is $0.1/kWh, and we still use the above figures, then the amount of money you can save on your TV in a day is 0.5kwh * $0.1/kWh = $0.05. And you can save 1.5 dollars in a month and 18 dollars in a year.
3. Tips to reduce TV power consumption
Unplug your TV in time: This is one of the most common and best ways to save energy, when you don’t use your TV, your TV will be in standby mode, so it still needs to consume electricity. Therefore, you can unplug your TV when you are not watching it.
Adjust the brightness and contrast of your TV: Nowadays, TVs are shipped with high brightness and high contrast settings, which will consume more power and cause more damage to your eyes. You can reduce the width and contrast according to your actual situation, but it will not affect your viewing quality. It will not affect the quality of the picture you are watching, and it will not only help to reduce the battery drain, but it will also be better for your eyes.
Use energy-saving modes: Many TVs come with built-in energy-saving features, such as sleep timers and eco-mode settings, and when you use these energy-saving features, your TV’s power consumption will naturally decrease.
Upgrade to an energy-efficient TV: Among the modern types of TVs, LED TVs are one of the more energy-efficient types of TVs, which use less power than regular TVs, mainly because LED TVs use light-emitting diodes to light up the screen, making them more energy-efficient than traditional TVs.
Using other power generating equipment to supply electricity: For families, the more common is the solar power system, as an example, the solar power system generates electricity through the sunlight to provide power support for the TV, in this way, the TV needs to consume less power from the grid.
Conclusion:
In conclusion, there are many factors that affect the power consumption of a TV, so you can use the above calculations to get an idea of how much power a TV consumes. And we have also provided you with some ways to reduce the power consumption of your TV, you can reduce your TV’s electricity bill by using the above methods.
