Solar Charger for Electric Bike – All you need to know

Solar Energy has been around ever since the sun came into existence. However, humans have discovered the technology to convert solar energy to electrical energy in the last 300 years.

However, the use of solar energy as a primary energy source is fairly recent. With the many conversations, around sustainability and renewability that we’re now having, solar energy plays a very significant role.

Many citizens are now finding alternate ways of powering their houses via solar power to reduce their carbon footprints. They’re doing so by installing solar panels to power their house or even by opting for solar chargers do different devices.

Here’s where the solar charge for electric bikes comes in. People who use electric bikes may also want a sustainable way to charge their bikes besides using an environmentally friendly method of transport.

These chargers are available in various shapes and sizes. They also have different applications and benefits. There are also other methods of using solar panels to charge your electric bikes that people may not be aware of.

Electric bikes require a fair amount of electricity to recharge. To fully charge an electric bike’s battery, you would need an uninterrupted supply of electricity for 90 minutes. This period is fairly long, which is why many conscious bikers are looking for alternates to it.

There are many aspects that one should look for when looking for a solar charger for electric bikes. We list all that you need to know, below.

What Is a Solar Charger?

A solar charger is a combination of a solar panel and a battery pack in a single device. These devices are similar to any other battery pack except that they have a small solar panel constantly saving solar energy using a pack.

Solar chargers are usually small in size and thus you don’t have to worry about carrying these chargers around. They have an internal battery that you can charge using the energy stored in the integrated solar panel.

These devices do not enable very quick charging; however, they can save your life in case of an emergency.

Factors to Consider Before Buying a Solar Charger for an Electric Bike

As stated earlier, a solar charger for an electric bike has two major components: the panel and the internal battery. So, when you’re looking at a solar charger for electric bikes there are other things that you’d have to take into account to understand if a solar charger is the best choice for you.


In terms of the solar charger, the internal battery of the charger should have significant wattage. If it doesn’t, you’re might not have a charger that can support the journeys on your bike.

It’s best to have wattage in this charger that allows for your bike to have at least one full charge for your electric battery in case something goes wrong.

However, some people don’t feel the need to own a solar charger that can provide such great power. Instead, they want something that can only help them in emergencies after which they can charge their electric bike by regular means.

You would have to look into the wattage as it also helps you identify how much power your solar charger can provide to your electric bike so that you can complete your journey. The wattage also depends on the electric bike you own.

If your electric bike requires a lot of power, you might need a greater amount of capacity than if your electric bike is more compact and has different specifications.


Apart from wattage, you should also note the capacity of the solar charger’s internal battery. The greater the capacity, the more charge can it provide to the electric bike. This means that it can change the speed with which you’ll travel.

Additionally, you should also buy a solar charger that has a panel of the correct capacity. If the panel itself can’t recharge your electric bike, it’s probably not best to have it.

You also have to choose whether you want a smaller panel or one that’s bigger. Bigger panels generally have greater capacity compared to smaller ones.

These big panels also charge your devices more quickly. Hence, if you have a portable panel with your solar charger and that panel has a greater capacity, you’re likely going to get back on the road again very easily. You may have to look at the capacity of different panels under different conditions.

Because as we stated before, some panels perform well even in cloudy conditions while others need peak sunshine to perform. So, depending on the time of the place you live in, you can pick a few chargers.

Output Power

You should know the output power of your solar charger. Knowing the output power will help you have a better idea of what you can expect from the solar charger.

You have to ensure that the output power that’s written on either the panel or the solar charger is one that you can charge your vehicle with, to the degree that you want.

Manufacturers have different ways of describing the output power. Some of them mention amperage through one port. At other times, they describe maximum power through both. If you don’t look at one or more of these carefully, you’d have a problem as you won’t get the appropriate solar charger.

Another practical consideration for you to note is the location that you’d be using these solar chargers in and so if you’re likely to use it in a bright, sunny place, it will charge quickly and easily. Its power output will be very clean and uninterrupted as a result.

However, if you’re more likely to use these chargers up in the mountains or somewhere that the weather is always overcast, the output power may dwindle due to weather conditions.


You must understand the purpose of your solar charger before you buy it. You might want a solar charger that you can whip out during emergencies to get to your next location. This would change your requirements for a solar charger.

If you want your solar charger to be your only charger so that you can lead a more environmentally conscious life, you’d need something with a greater capacity and is durable.

If you want a solar charger for a backup but have enough energy to recharge your electric bike completely, pick one with a greater capacity. In any case, you must define the purpose of your solar charger before you jump to make a purchase.


Solar chargers are expensive so you must ensure that the one you get is durable. Durability in solar chargers would entail durability in their solar panels. The solar panels should be functioning at optimum capacity.

Durability also means that these solar chargers are not easily damaged. They should occur in a protective case so that the wear and tear they undergo doesn’t affect their durability.

Some solar chargers use solar panels in a blanket-like device so they’re protected from external factors and don’t face any harm.

Solar chargers are generally very easy to install but since there’s a vast variety of chargers available in the market, you should ensure that installation is a factor you look into. If you’re not well-versed in how your electric bike works, you’ll likely have to enlist the help of a bike mechanic to help you install the solar charger.

This will likely cost you extra money, resulting in a much more expensive purchase. Instead, if you use a solar charger that’s easy to install, you’ll have to spend less money and have it be more convenient.
