These days, using solar energy for everyday tasks is getting a lot of attention.

It’s a smart way to cut down on energy costs and be kinder to the environment.

And you might wonder, can we use solar power to run our TVs?

The good news is, yes, we can.

*You need at least a 100W solar panel system to power a TV.*

In this article, I will guide you in figuring out just how many solar panels are necessary to power your TV.

**Key Takeaways**

- To calculate how many solar panels you need to power your TV, first figure out your TV’s energy usage, which you can find in the TV’s manual or online.
- Determine your local peak sun hours to understand how much energy a solar panel can produce in your area, which varies based on location and weather.
- Calculate the theoretical size of your solar system by dividing your TV’s daily energy consumption by the peak sun hours, then adjust for system losses.
- Find out the number of solar panels by dividing the required system size by the wattage of the solar panels you plan to use.

**How to Calculate the Number of Solar Panels You Need to Run a TV?**

**1. Calculate Your TV Energy Consumption**

Before we start, it’s important to determine how much energy your TV uses.

You can do this by referring to the owner’s manual or searching online for the power consumption of your specific model.

I use a ** 50-inch LCD TV** and it consumes around

**when it’s in use.**

*60 watts per hour*If I use it for ** 6 hours a day**, we can calculate the daily energy consumption of my TV as:

*Total Daily Consumption = 6 x 60 Watts = 360 Watt-hours (Wh)*

We’ll be using this figure in our calculations later.

**2. Find out Your Peak Sun Hours**

How much energy a solar panel produces depends on how much solar irradiance it receives.

However, the sunlight intensity varies greatly throughout the day and highly depends on the weather and season.

Sometimes the solar irradiance can be ** 300W/m²**, while at other times, it can be

**.**

*1,000W/m²*So to make calculations easier, solar experts use something called “peak sun hours” (PSH).

Peak sun hours refer to the number of hours per day when the solar irradiance is ** 1000W/m² per hour**.

For example, if the peak sun hours for your location is ** 4.5**, it means that your solar panels can generate up to

**of energy per day.**

*4,500 Wh*You can use the NREL calculator to find the peak sun hours for your location.

I live in California, so I’ll use ** 5.83 peak sun hours** for this example.

**3. Calculate Your Theoretical Solar System Size**

We now have all the information we need to calculate the size of our solar system.

Using the formula below, we can figure out how many watts of solar panels we need:

*Required Solar System Size (in Watts) = Daily Energy Consumption (Wh) / Peak Sun Hours*

So for my ** 50-inch LCD TV**, I’ll need:

*Required Solar System Size = 360 Wh / 5.83 hrs = 61.8 Watts*

So, to run my LCD TV, I’ll need at least ** 62 watts** of solar power.

But this is just the theoretical size under perfect conditions.

We still need to factor in some losses due to things like shading, dirt accumulation on the panels, and other losses.

**4. Factor in Solar System Losses**

Any solar system will experience some losses due to factors like shading, inverter efficiency, thermal losses, dirt accumulation, wiring resistance, and other factors.

These factors will affect the actual output of your system, so it’s important to factor them in when calculating the size of your solar system.

The industry standard for losses is around ** 14%**, so we can use this figure to calculate our actual solar panel size:

*Actual Solar System Size (in Watts) = Required Solar System Size (Watts) x 1.14*

So my actual solar system size will be:

*Actual Solar System Size = 61.8 Watts x 1.14 = 70.5 Watts ~ 71 Watts*

This means that I’ll need at least ** 71 watts **of solar panels to run my LCD TV.

**5. Calculate the Number of Solar Panels**

Solar panels are rated by their power output, which is measured in watts.

Most solar panels’ wattage ratings on the market range from ** 250W to 400W**.

This wattage rating refers to the amount of power that the panel can generate under peak sun conditions per hour.

For example, a ** 100W solar panel** will generate

**of power per hour when the sunlight is at**

*100 watts***.**

*1,000W/m²*Say we’re using a ** 100W** solar panel.

To calculate the number of panels we need, we’ll use the following formula:

*Number of Panels = Actual Solar System Size (Watts) / Rated Power Output of Each Panel (Watts)*

So for my** 71-watt **system, I’ll need at least:

*Number of Panels = 71 Watts / 100W = 0.71 ~ 1 Panel*

This means that I’ll need at least ** one 100W solar panel** to run an LCD TV.

**What Battery Size Would I Need to Run a TV?**

Solar panels generate DC electricity, but they don’t store it.

This can work if you’re running your appliances during the day, but what happens when it gets dark?

That’s where solar battery systems come in.

A solar battery system stores the excess electricity so you can use it later at night when the panels aren’t producing enough power.

To calculate the size of the battery, you can use the following formula:

*Battery Size (Ah) = Solar Panel Daily Output (Wh) / Battery’s Voltage (12/24V) / DoD (0.5/0.75/0.8)*

In our example, to calculate the solar panel’s daily output, we can use the following formula:

*Solar Panel Daily Output (Wh) = Number of Panels x Rated Power Output per Panel (W) x Peak Sun Hours x (1-0.14)*

So, for my LCD TV example, the daily output of the solar panel will be:

*Solar Panel Daily Output = 1 panel x 100 Watt x 5.83 hrs x 0.86 = 501.38 Wh*

Now, let’s assume I’m using a ** 12V solar battery** with a Depth of Discharge (DoD) of

**.**

*50%*My battery size will be:

*Battery Size (Ah) = 501.38Wh / 12V / 0.5 = 83.6 Ah ~ 84 Ah*

So, I’ll need a battery of approximately ** 84 Ah** to run my LCD TV.

I’ll also need a charge controller to regulate the current and avoid overcharging the battery with solar panels.

**Do I Need an Inverter to Run a TV on Solar Power?**

You need an inverter to run an LCD TV on solar power.

Solar panels produce DC electricity, while most household appliances like TVs run on AC electricity.

Inverters convert DC power from solar panels into AC power so that your TV and other appliances can use it.

The size of the inverter will depend on the type of solar system and your power requirements.

For instance, if you want to power a full PC setup on solar energy, you’ll need a larger inverter than you’ll need to power just a TV.

If you’re using a grid-tied solar system, to calculate the size of the inverter, use the following formula:

*Inverter Size (Watts) = Rated Power Output of Each Panel (W) x Number of Panels x **1.15*

For our example, the size of my inverter will be:

*Inverter Size = 100 Watt x 1 panel x 1.15 = 115 Watts*

But, if you’re using a small off-grid system, you just need to add up all of your appliances’ power requirements to get the size of inverter you need.

For example, if you have an LCD TV with a power requirement of** 200 Watts**, a laptop with a power requirement of

**, and a few other devices that add up to**

*30 Watts***, then your inverter size will be:**

*50 Watts**Inverter Size = 200W + 30W + 50W = 280 Watts*

So, you’ll need an inverter of approximately ** 280 watts **to run all these appliances.
