How Much Energy does a TV Use?

High-definition television, and all the components that make up your home entertainment system, has become a fixture in every household. The television and home theater can also be one of the major power users within the home. To calculate the electricity needed to power a TV, you can first start with the yellow and black energy guide label that comes on the TV, which is required by the FTC to show a cost estimate of how much it costs to run that set for a year, averaging five hours per day. The next step, especially if you no longer have that label, is to turn to the manual. The documentation should offer insight into how many watts the TV model consumes. Though power consumption varies by the size of a TV, and the technology it uses, most TVs use about 80 to 400 watts, according to most sources. With an average five hours of viewing per day, that's about 12 to 61 kilowatts per month or 147 to 733 kilowatts per year.

To offset your prime time viewing habits, you might consider installing a home solar power system. This requires home solar panels, a generator and batteries. Most of these items are packaged together in a kit. All you have to do is determine how much power your TV or home entertainment system requires to run. If you want to go beyond your TV for this installation, be sure to calculate the power consumption needs of every component, including your TV, cable box, Blu-ray or DVD player, game console, audio receiver and any other components you may want to run on this system.

One home solar system option is the 1800 Watt Solar Generator Complete with two 100 AH Batteries and 160 Watts of Solar Panels. The package should have your home theater setup covered, and is capable of powering up to 1800 watts. The generator has an 1800 watt inverter with four 115 VAC power outlets to operate multiple devices. A digital LED display can be viewed to determine battery capacity status, and other data such as the wattage of devices connected to the unit.

The comparable Earthtech Products 1800 Watt Solar Generator Kit with 300 Watts of Solar Power Panels comes with a power hub generator, three 100 watt solar panels, and amp charge controller, two batteries and hardware for installation. It supports up to 200 amp-hours of power from its solar panels.

Determine your needs, and find the system that's right for your home.
