Solar Powered Light Bulbs: Can Solar Generator Power Light Bulbs

Solar-powered light bulbs are a popular way to illuminate your garden pathways, walkways, or landscaping during the night. Not only do solar lights enhance the beauty of yards and outdoor areas, but they also help conserve electricity.

A solar light bulb consumes around 2-18 watts of power, depending on its style, type, and brand.

Homeowners can choose a robust and reliable Jackery Solar Generator to charge solar light bulbs. They are cost-effective and eco-friendly charging solutions for all small and large appliances, including light bulbs.

In this guide, we will reveal everything related to solar-powered light bulbs and how to charge them using solar generators.

What Is A Solar Powered Light Bulb?

Solar lights are devices that capture the sun's energy using solar cells. The PV solar panels convert sunlight into electricity. The wires connect the solar panel to the battery that stores the generated energy for later use.

When the darkness falls, the rechargeable battery (often made of lithium ions) powers the light bulb. The light-emitting semiconductor diode allows electrons to pass between the two points, creating electromagnetic energy.

Some of the main benefits of outdoor solar lighting include the following:

  • Long Lasting:¬†Thanks to the combination of solar panel technology and LED bulbs, solar-powered lights last longer than other types.
  • Cost Saving:¬†Since solar lights rely on sunlight, they won't increase electricity bills.
  • Suitable For Outdoors: Solar lights are pretty portable. That being said, you can install them anywhere in your outdoor space.
  • Illumination During Power Outages:¬†Even if there is a blackout in your area, the solar lights will still work due to the sun's energy.
  • Eco-Friendly:¬†Unlike power sources that use fossil fuels, solar lights are powered by renewable energy. Hence, they are an eco-friendly option.

Solar Powered Light Bulb Vs. Solar Generator For Light Bulb

When it comes to charging light bulbs using solar energy, you have two options available: a solar-powered light bulb or a solar generator. Both are popular options for people wanting to light their space with clean and green energy.

While solar-powered light bulbs are easy to install and portable, they may not be as bright as traditional ones. Choosing a solar generator for light bulbs ensures you can power multiple light bulbs and other electrical devices simultaneously.

Let us quickly compare the two charging solutions below.

  • The high power capacity of the solar generator helps you charge not only light bulbs but also other home appliances during¬†off-grid living.

 Cons

  • They are more expensive compared to¬†solar-powered light bulbs.

How Many Watts Does A Solar Light Bulb Use?

A watt hour is the unit of energy commonly used to indicate the consumption of one watt of power expended for one hour.

On average, an LED light bulb solar-powered uses 10 watts of power. However, the exact wattage might differ depending on size, manufacturer, and other factors. You can find the wattage of your LED light bulb on the device or in the user manual.

How Much Does It Cost To Power A Light Bulb?

The cost to power a light bulb will depend on the watt consumption, the energy rate, and how many hours you use the bulb.

Suppose the LED light bulb consumes 10 watts of power and runs for 5 hours per day. Then, the power consumption will be:

Power = 10 watts √ó 5 hours / 1000 = 0.05 kWh.

That said, a light bulb will consume 0.05 kWh in one day. The exact cost for 0.05 kWh usage will depend on the electricity rate of your location.

Here is an average cost calculation for a LED light bulb in the US that uses 10 watts of energy and runs for 5 hours daily.

How Much Solar Power Does A Light Bulb Need?

The solar power of a light bulb depends on the watts consumed by the appliance and the time it runs.

A light bulb that uses 5 W of energy and runs for 8 H will consume around 40 Wh of power. If you are using more than one light bulb, you can calculate the power consumption of each bulb and add them to find the total energy usage.

Solar Powered Light Bulbs FAQs

What size of solar generator do I need to power light bulbs?

As light bulbs require less number of watts to work, you can charge them using a small size solar generator. However, the exact size will depend on the watts one light bulb consumes, the usage time, and the number of light bulbs you wish to power.

Let us assume that you are using Jackery Solar Generator 1000, which has a battery capacity of 1002 Wh.

Working time =  1002 Wh * 0.85 / operating wattage of your device.

If one light bulb consumes 10 watts of power and you want to charge 5 similar light bulbs, the total power consumption will be 10 watts * 5 = 50 watts. 

Working time =1002 Wh * 0.85 / 50 = 17 hours.

Note: The pass-through feature ensures that you can power the generator and the electrical devices simultaneously. Thus, you can never go out of power if you have a Jackery Solar Generator by your side.

How many solar light bulbs do I need?

The number of solar lights will depend on the amount of outdoor space you wish to illuminate. Then, you can measure the distance between the existing lights, bushes, and trees. Now, calculate the amount of square footage that each bulb can illuminate. Finally, divide the number by the overall square footage to calculate the total number of solar light bulbs required.

Can I charge light bulbs on cloudy days, in winter, or without the sun?

In a word, yes. A solar generator can help you power all electrical devices, including light bulbs, on cloudy days, in winter, and without the sun. Jackery Solar Generators is a team-up of highly efficient solar panels and portable power stations that can convert and store the maximum amount of sunlight that falls on them.
