What Is A Solar Radio And Who This Is For
Like all things solar, the solar-powered radio operates on solar energy. It is basically the typical radio having a different power source: the sun.
Through the panels, this solar energy is converted to electricity that is responsible for powering up the radio. As such, how long the radio operates depends on the charge it got from the sun.
The very first model was made in the 1950s by the company, General Electric. What began as an experiment quickly evolved and turned into an important innovation.
Using the sun’s energy, this solar AM FM radio eliminates the need for batteries and/or plugging it into a power source.
Because of this, the solar-powered radio has indeed, became quite popular, especially among areas that are prone to power failures and outages. With this, people can still obtain information via the radio despite having no electricity.
Moreover, as there are no wires required or plugging necessary, the solar-powered radio can be used anywhere. This is perfect especially for those who are constantly travelling or for the avid fans of outdoor activities such as camping, hiking, and the like.
The solar-powered radio is also ideal for those looking for eco-friendly alternatives. Aside from reducing one’s carbon footprint, it also helps in saving electricity and household bills.
Aside from that, solar-powered radios are also recommended for those living off the grid or are planning to. The solar-powered radio generates its own electricity via solar energy. In other words, it can be charged on its own. Thus, one can definitely conserve and save on the electricity stored in the battery bank of one’s solar system.
How Does It Work
In a solar-powered radio, there are two ways to collect and obtain solar energy.
The first way is what most solar-powered devices usually used and generally, what people are used to. Here, the solar-powered radio is equipped with PV panels that collect and absorb sunlight.
The sunlight then goes to semiconductors that are connected to two contact points. Once photons, or light particles, enter the semiconductors, these then quickly remove the electrons in their atoms. In other words, solar energy is transformed and converted into electricity. Electricity then courses through the device, powering it up.
The second method is generally not preferred since it cannot really sustain in running the radio. This approach espouses the same principle used in running solar ovens. Here, solar energy is collected by metal reflectors, panels, mirrors and other reflective surfaces.
These reflective surfaces then direct the sunlight into an insulated box that in turn, generates heat. This heat powers a turbine in order to produce electricity.
Despite the differences, these two methods both rely on solar power. As such, how long the radios will last depend on the charge they got.
There are also some models of a solar powered am FM radio that comes with batteries. After the electricity has been generated, there are some that goes into powering your device. The other half then goes to the battery for storage.
This way, one can still use the solar radio even during nighttime. It is also beneficial during winters, storms, or in days when there is barely any sun.
What Are The Different Types Of Solar Radios
Solar-powered radios are certainly popular due to the numerous benefits they offer. As such, there are a lot of versions and types in the market.
Solar-powered radios can be differed based on two factors: method of collecting solar power and power sources.
First, solar-powered radios differ on the method or way of collecting and storing solar energy.
The first type uses solar panels to absorb and collect solar energy. The light particles or photons are then transmitted into semiconductors that are connected into two crucial contact points.
When the semiconductors receive the photons, they then remove the electrons present in the atoms. With this, the solar energy is then transformed into electricity.
The second type relies on heat to generate electricity. Here, the solar radio is equipped with mirrors, metal reflectors, panels and other reflectors in order to reflect and refract sunlight into an insulated box.
After that, heat is then generated which is used to power a turbine found inside the device. The turbine then generates electricity that is used to power the solar radio.
Despite their differences, both of these types rely on solar energy in order for the radio to work. How long the radios will work depends on the solar power it stored and is charged with. There are also some versions of these types that come with a battery.
The battery then stores excess electricity generated. As such, you can still use your radio during overcast days, storms, typhoons, days that do not generate a lot of solar power. Batteries are also useful during winters and for nighttime usage.
Second, solar-powered radios also differ on their power sources.
There are versions that purely rely on solar power. However, these models are not effective during overcast days, storms, as well as during winters.
Some versions can be charged via solar energy and via electricity through a USB cable. With the USB cable, you can still use the solar radio during overcast days. However, it might not be preferred for those looking to save on their electricity bills and for those who do not have a stable electricity source.
There are also some versions that come with a hand crank. Most users generally prefer this version. When the weather is less than ideal, you can always opt to use the hand crank to generate small amounts of electricity. However, the downside is that it can get a bit tiring.
If you need more information about solar products, we have a list of solar-powered watches for your reference. Furthermore, check out the top-tier solar atomic watch guide if you like.
Advantages And Disadvantages Of Solar Radios
A solar-powered radio is the typical radio that collects and converts solar energy in order for it to generate electricity. How long the radio will last depends on the charge it got on that day.
However, while the solar-powered radio is certainly useful, like all devices, it has its own fair share of advantages and disadvantages.
Knowing these is essential for a buyer to know what to expect from their device and thus, increase overall customer satisfaction. With this information, they will also be able to weigh down on whether the device can suit their needs or not.
Due to its reliance on the sun, the solar-powered radio eliminates the need for using batteries, and other fossil fuels. It is not only that, but you also eliminate the use of electricity. Thus, you can do your part in alleviating and helping in conserving the environment.
Solar energy is also a clean energy source, meaning it does not produce any type of pollution nor does it harm the environment. With the solar-powered radio, you can reduce your carbon footprint little by little.

It is also not useful during overcast days, storms and the like and for those living in colder climates. While there may still be sunlight, it might not be enough to power up and sustain the radio.
How We Picked And Tested
Solar-powered radios are a great way to conserve the Earth’s resources and save on electricity. Due to their design, solar-powered radios are usually used for emergencies, those who frequently travel or engage in outdoor activities or for those who live in remote areas and places.
With its numerous benefits, solar-powered radios are certainly popular. As such, there are a lot of styles and types available in the market that can make choosing one a bit daunting and overwhelming.
The best solar radio hinges on how well it can suit your needs. Thus, it mostly depends on you. However, there are a few key factors you need to remember when shopping. This article will highlight such elements.
Charge Time and Life
A good rule of thumb is to look for a solar radio that can last long and charge fast. As such, consider one that has multiple power sources. There are some models that are solar-powered but that also come with batteries, or they can be charged via USB. There are also hand cranks which relies on the effort you put it.
With these extra power sources, you can definitely use your solar radio for a longer period of time. Moreover, this makes the device more reliable as there are situations where the sun is absent.
It is recommended to get a model that comes with battery. That way, it can store some electricity to use in cases where the solar power is not enough.
Solar radios should also be durable and sturdy as there are some people who use them for emergencies or bring them with them during outdoor activities.
Look for a model that is at least waterproof. This way, you are assured that your unit can at least withstand water, rain and storms.
It is also recommended to purchase one that is shockproof or at least resistant. This way, you would not have to worry about bumping the device or it falls.
Logos and certifications
One thing to ensure that your solar radio is indeed durable is to check the various logos and certifications on your device.
Check its IP-rating and other pertinent logos. For those who want to use the radio for emergency purposes, look for the All Hazards or Public Alert logo. With this, your radio is approved and is expected to receive alerts during emergencies.
Of course, one of the most important factors you need to consider is the volume of your radio. This element, however, is more of a preference and usually depends on what you will use it for.
For general, everyday use, you do not really have to purchase one that is incredibly loud. Just find one that can generate a decent amount of volume. If you want, you can also purchase one that has an AUX port. That way, you can use your earphones if you like.
Size and Weight
Again, this factor is usually more of a preference and depends on how you will be using the device. For one, consider if you would like to carry it with you anywhere or if you just want it at home.
For those who are frequent travelers or those planning to use it during emergencies, then a smaller and lightweight radio is recommended. That way, it would not be too much a hassle in carrying it.
Otherwise, if you just want the radio to be at your home, then you can buy the bigger and bulkier versions. These tend to be more durable and offer more features.
Solar radios are generally used to obtain news and other information. However, there are some versions that offer than that. Choosing to purchase one that comes with different features is a matter of choice.
There are solar radios that have different power sources, act as a power bank and come with hand cranks. There are also versions that give you the option of using headphones or speakers. Another version features a flashlight that is perfect for those who want to use the radio during emergencies.
If you are thinking of purchasing a model that offers different features, opt for one that has different power sources aside from solar power. It is also useful to buy one that comes with batteries or one that has a hand crank. It is also useful to purchase a unit that can charge your phone.
Frequently Asked Questions
How do you make a solar radio?
Making a solar powered shortwave radio is easier than most people think. You only need an old or rarely used battery-operated radio, preferably made with a waterproof casing, to form the project’s foundation.
We must emphasize “battery-operated” because solar systems produce DC electricity. You could use an electric radio, but it will require an additional inverter to transform DC power into AC energy.
Making a radio with solar panel requires correlating the solar panel’s energy output with the radio’s power requirements, or at least close to it.
For example, if the radio requires 6.0 DC volts (four 1.5V AA batteries), your solar panel must deliver at least six volts. Alternatively, a 4.0 or 4.5-volt solar panel from a solar light will suffice.
You will also need at least 800mAh NiMH or lithium-ion rechargeable batteries, electrical wirings, solder and soldering iron, and a BAT43 Schottky diode to complete the solar powered waterproof radio.
Making a solar powered ham radio requires preparing the repurposed solar panel and connecting its wires to the old radio’s power terminals. Next, secure the blocking diode and the solar panel before final assembly.
Is a solar shortwave good for emergencies?
Yes, a solar shortwave radio is perfect for emergencies because most transmissions in such events use shortwave frequencies, including emergency alerts and NOAA weather access. Natural and man-made disasters can destroy power and telecommunications infrastructure, rendering conventional radios useless.
A solar crank radio is also excellent for emergencies because it does not require batteries. The system transforms mechanical energy (hand cranking the radio) into electrical power to receive emergency weather updates and disaster-related news.
Solar-powered shortwave radios with an integrated hand crank mechanism are the top-rated during emergencies because they do not rely on electricity. Even in stormy weather, the crank system enables people to listen to crucial warnings, alerts, and updates.
Some solar shortwave and hand-cranked radios can also serve as a flashlight and phone charger, allowing users to illuminate their surroundings and boost communication lines. These solar charger radio units are indispensable in emergencies.
Can I just use my phone instead of a solar radio?
Yes, you can. For example, you can turn the phone into a solar powered FM radio for cars with a few tweaks, allowing you to enjoy radio streaming services.
In addition, some smartphone apps also empower users to transform their devices into ham radios or walkie-talkies, such as X-TALK. Motorola’s WAVE PTX is another app that converts smartphones into two-way radios.
However, even with these apps that give your phone traditional radio features, they will be pointless without power supply. For example, natural calamities can topple electric posts and put a location in a blackout. And a fully drained phone battery won’t be able to function as a radio.
On the other hand, a waterproof solar powered radio can continue entertaining, informing, and alerting you amidst power failures and non-functioning telecommunications infrastructure. You do not need batteries, making this radio type indispensable for outdoor enthusiasts, off-grid families, and emergency responders.
The advantage of turning your smartphone into a solar radio is it already has Bluetooth functionality for effortless connectivity. The phone can also be charged with USB port, which is considerably faster than using solar energy.
What are the most trusted solar radio brands?
While there are undoubtedly an unlimited number of brands for a solar radio, not all of them can give you the satisfaction you are looking for because they are not reliable. You might want to check out FosPower, RunningSnail and RegeMoudal.
