Solar panels are pretty incredible, and the idea of free energy without having to put in any work is very attractive to many people. Since solar panels are only recently becoming easy to gain in normal households, it’s understandable you might want to start out with something small.
When choosing your first solar panel, consider the 1.5-watt solar panel. These solar panels can fit in the palm of your hand while also having enough power to charge your favorite devices.
A 1.5-watt solar panel is indeed diminutive, but what’s the point of such a small panel? What can I do with a 1.5-watt solar panel?
A 1.5 watt solar panel can charge everything from a small powerbank all the way up to a 12-volt car battery, and best of all, it’s portable!
In this article, we’ll go over the size of a 1.5-watt solar panel, how much power it has, some things it can charge, and if it’s a must-have for solar-power-loving consumers.
Solar power and all its nuances may seem complicated from the outside, but once we explain all the nitty-gritty details, you’ll be ready to buy your new solar panel with no hesitation!
What Can You Charge With a 1.5 Watt Solar Panel?
Simply put, a 1.5-watt solar panel can charge anything that is compatible with a 12-volt battery
For example, one of the most significant things that can be charged with a 1.5-watt solar panel is a 12-volt vehicle battery. If you are unable to start your vehicle to charge the battery inside of it, hooking it up to a 1.5-watt solar panel will get the job done.
Charging a car battery can take a good amount of time, though, so don’t set your expectations too high for a super fast charging.
Besides vehicle batteries, 1.5 watt solar panels are great choices for charging phones and power banks alike. Many outdoor activities prevent you from being able to charge your phone or powerbank the traditional way, but to use a solar panel to charge your electronics, all you’ll need is the panel and the sun.
One way to guarantee that you always have battery power available is to keep two power banks on hand. This way, one power bank can constantly be charging on your 1.5-watt solar panel while the other is providing power for your phone.
1.5-watt solar panels are the perfect camping accessory, too, especially if you’re using rechargeable flashlights.
You can leave your 1.5-watt solar panel sitting next to your tent to charge, or if you’re concerned about it being stolen, on the dash of your car parked in the sun is another decent choice. Nothing is worse than running out of flashlight power while camping at night!
Other than camping, there are a few more outdoor uses for 1.5-watt solar panels. Gardeners love to use these panels to power wireless solar outdoor lights or birdbath water pumps. When left out all day in the sun to charge, the 1.5-watt solar panel can keep an outdoor light illuminated for over 6 hours!
Decorative string lights have become an increasingly popular outdoor lighting solution, so instead of worrying about plugging and unplugging your string lights every night, hook them up to 1 or more solar panels for autonomous lighting.
How Many Volts Does a 1.5 Watt Solar Panel Produce?
A 1.5-watt solar panel will produce 12 volts of power.
This means that a 1.5-watt solar panel can charge anything that is compatible with a 12-volt battery.
How Big is a 1.5 Watt Solar Panel?
Since different solar panels are produced by different companies, their specifications, size, and shape can vary slightly, but for the most part, they’re smaller than the average laptop and can fit in most backpacks.
1.5 watt solar panels are usually small and made to be portable, so you can take them on the go. Their small size makes them perfect for activities like camping, hiking, or long road trips, and they can provide decent charging power even when off the grid.
To give you an idea of the size of these solar panels, we’ll list the size of 3 of the most popular brands of 1.5-watt solar panels from Amazon and their sizes below:
- The Joytech 1PC 1.5w 5.5v 270ma Mini Solar Panel Module DIY Polysilicon Solar Epoxy Cell Charger B008-
5.91 inches tall by 3.66 inches wide
4.53 inches tall by 3.54 inches wide
4.49 inches tall by 2.72 inches wide
As you can see, these solar panels differ slightly in size, but they usually are within an inch or two of each other.
Being so small means you can take them almost anywhere. Having a power bank to charge your cell phone when you’re away from outlets for a long period of time is a great idea, but eventually, even the power bank will run out. To give yourself the best chance of keeping everything charged, consider a 1.5-watt solar panel.
How Much Does a 1.5 Watt Solar Panel Cost?
1.5-watt solar panels will cost between $5 and $20 dollars, with prices varying depending on the brand, location, quality, and other features.
1.5-watt solar panels are some of the cheapest solar panels you can get and are relatively easy to find in stores compared to their much larger and costlier counterparts.
To get the best deal on your solar panel, shop around, comparing prices and reviews to make sure you get the best product for your money.
Can You Connect Multiple 1.5 Watt Solar Panels?
It might seem obvious that more power is better, but in fact, too much power can short circuit smaller electronics. So while you can connect multiple 1.5-watt solar panels to produce more power, they won’t be suitable for powering the small devices that we mainly use these solar panels for.
Yes, you can absolutely connect multiple 1.5-watt solar panels. Each panel will provide 12 volts of power, so be cautious that you aren’t overpowering and short-circuiting whichever electronic you hook up to your connected panels.
Connecting solar panels can work well for projects like extensive outdoor lighting, but it’s almost always less expensive to purchase fewer large panels than a huge amount of smaller ones. The fewer panels you have to connect and deal with, the simpler your project will be.
Where Can I Purchase a 1.5 Watt Solar Panel?
Online retailers like Amazon and hardware stores like Harbor Freight, Home Depot, and Lowes all carry a decent variety of 1.5-watt solar panels.
Do your own research before deciding on which solar panel to buy, and this includes researching the best solar panel for the object you’re planning on charging.
It’s frustrating to think that the smaller solar panel you’ve purchased will be powerful enough to run a new electronic, only to find out a larger solar panel is needed. Avoid these disappointments by learning all you can about your solar panels and what they will charge before purchase.
It’s also important to look at reviews when possible. Finding out the benefits and shortcomings of certain 1.5-watt solar panels is invaluable when making a new purchase because knowing how the product performs for real people will give the best idea of the quality of the product.

Can solar panels charge without direct sunlight?
Yes, any light, including indirect and artificial light, will charge a solar panel. Sunlight is the quickest and most effective form of light, but other sources will work in a pinch.
Can I leave the solar panel on at all times?
Yes, you can leave your solar panel on at all times with no problems, but to maximize efficiency, make sure that the panel stays clean and is unobstructed from receiving sunlight.
Can solar power save me money?
Yes, solar power will save you money by reducing the electricity you use and pay for in your own home. With small panels like a 1.5-watt solar panel, the savings will be negligible, but the larger the panel, the more you will save.
