What solar panel size (watts) do you need for a TV?

While a solar panel can generate enough power to run your TV (you need a specific setup for it to work safely), the size of the solar panel (watts) required mainly depends on:

  • the TV’s power consumption. The larger the TV (screen size), the higher its power consumption
  • the peak sunshine hours for your location. A location with fewer hours of sunshine, will need a larger capacity solar panel (watts) for example.
  • how many hours a day the TV will be working. The more hours the TV operates for in a day, the more the number of watts of solar that is needed
  • whether the solar panel supplies power to the TV only or there are other appliances that require the solar panel’s energy. If it is used for other appliances, you need to increase the number of watts.

As a general guide, a 100W solar panel can generate enough electricity to supply a 32 – 40 inch TV for an estimated 4 hours a day. This assumes a daily energy consumption of 160 – 227 Wh. Check your TV’s technical specifications to confirm.

Larger TVs with screen sizes such as 43 – 50 inches, will likely need solar panels rated 150W – 200W.

Note:

The power consumption values (watts) are estimates. Always check the technical specifications section of your TV to confirm the actual power consumption.

The solar panel sizes assume that a location that receives at least 4 hours of sunshine per day.

How to connect a TV to a solar panel?

To power your TV reliably and safely with energy from a solar panel, you need the components listed below in addition to the solar panel (you cannot connect the solar panel directly to the TV):

  • Charge controller – for efficient and safe charging of the battery
  • battery – This acts as a reservoir to supply a steady energy source to the TV.

This is because the power output from the solar panel changes throughout the day depending on the amount of sunshine and temperature.

  • inverter (not required if the TV uses DC power)

Can a 200 watt solar panel run a TV?

Yes, a 200 watt solar panel can generate enough energy to run a 43 inch LED TV estimated daily energy consumption of 247Wh or a smaller size TV. This assumes that the TV runs for 4 hours.

This is based on the assumption that a 200W solar panel generates an estimated 560Wh daily – supplying 70% of its rated energy mounted in a location that receives 4 hours of sunshine.

Note that you would not be connecting the solar panel directly to the TV, instead, the solar panel would charge the battery through a charge controller.

The TV would be connected to the battery directly (DC TV) or to a power inverter connected to the battery.

Can a 100 watt solar panel run a TV?

Yes, a 100 watt solar panel can generate enough energy to run a TV 40 inch LED TV, or smaller. This assumes the TV has an estimated daily energy requirement of 227Wh which can be met by a 100W panel that generates about 280Wh daily.

The assuming here is that the solar panel supplies 70% of its rated energy and is mounted in a location that receives 4 hours of sunshine.

The TV would have to be either connected to an inverter or directly to a battery (DC TV) charged by the solar panel through a charge controller.

How many solar panels do you need to run a TV?

To meet the energy requirements of a TV, you can have one or more solar panels provided that it supplies enough power to meet the requirements of the TV. So, first, work out the recommended solar panel size (watts).

For example, for a 40 inch TV, based on the Table above, you can have:

  • 1 x 100W panel
  • 2 x 50W panels
  • 4 x 25W panels

Provided they meet the required energy requirement.

It is best though to keep the number of solar panels to a minimum to minimize the cost of cabling, energy losses, and convenience.
