Learn More About Portable Solar Panels…

Today, there are small solar panels on the market that can be taken with you wherever you go. To learn more about these nifty devices, follow this section…

What Are the Benefits of Portable Solar Panels?

The advantages of a solar charger are numerous:

  • Portable: designed to be easily transportable, they will be light and compact, guaranteeing effortless use in all circumstances.
  • Practical: thanks to them, you will no longer have to worry about the state of charge of the battery of your electronic devices or having to find an accessible electrical outlet nearby. Portable solar panels will allow you to recharge your devices quickly and easily.
  • Versatile: there are several types of solar panels on the market such as hybrid solar chargers equipped with a battery that will charge your devices at nightfall after capturing the sun’s rays all day.
  • Deliver clean energy that respects the environment: portable solar panels are ecological. They use a clean source of energy (the sun) without having to pollute the environment and do not reject toxic waste.
  • Provide free energy: apart from the cost of purchasing solar panels, you will not have to spend anything more to capture the energy from the sun, which is free.

What Are the Disadvantages of a Solar Panel?

The disadvantages of solar panels are few. We can cite the fact that to store enough energy quickly, they must be used in situations of optimal sunshine. To overcome this problem, a solar charger with a battery accumulator will be recommended (although they will require a longer charging time than conventional solar panels which do not).

Finally, some models may be subject to overheating or reliability problems for very first-price models. Heavy cloud cover or low sunlight will limit the performance of a hiking solar panel.

Where Can I Use a Portable Solar Panel?

As we have seen previously, portable solar panels are extremely practical and compact. You can use them in many situations and activities:

  • On a hike or trek: attached directly to your backpack, the solar panel will store energy without you having to do anything. Because of their lightweight design (between 250 and 450g), they will not be felt on your shoulders.
  • When camping: positioned in your tent, they will allow you to capture the sun’s energy when you are not in it to ensure you have a source of energy in the evening.
  • At the beach: have you decided to tan at the beach? Take the opportunity to take your solar panel and recharge the battery of your smartphone or an external battery.
  • On a picnic: placed next to your tablecloth, the solar panel will ensure that you immortalize all your memories without fear of draining the battery of your digital camera or your smartphone.
  • Traveling: you need to call a taxi or go to a meeting point but you have run out of battery? The portable solar panel will get you out of delicate situations for which your smartphone will be essential.
  • On horseback or mountain bike: just like hiking, you can position the solar panel behind your saddle when you go horseback riding or cycling.
  • Every day: slipped into your bag, you can recharge your smartphone at any time if you have a light source.

How Quickly Can I Charge My Smartphone with a Portable Solar Panel?

The charging time of a battery will depend on several factors: the power of the solar charger (expressed in Watt), the voltage of the electric current (expressed in Volt), and the capacity of the battery of the device to be charged (expressed in Milli Ampere per hour = mAh).

To determine the charging time, it will therefore be necessary to calculate: the battery capacity/current voltage/battery power. Of course, the level of sunshine will also be a parameter that will vary the result obtained. The level of sunshine will depend on:

  • The latitude at which you are located.
  • The season you will be using your solar panel.
  • The time of day you will be using your solar panel.
  • Weather conditions and cloud cover intensity.
  • Air pollution and the cleanliness of the surface of your solar panels.

For example, if you want to determine the charging speed of a smartphone with a 15W solar panel, you will need on average between 1h30 and 2h on a clear day and between 3h and 5h on an overcast day. To know more precisely the charging speed of a phone connected to a solar panel, there are applications for smartphones capable of providing you with this information (we recommend the “Charger Tester” application, available on Android).

Which Orientation Should I Choose for My Solar Panel to Optimize Its Use?

To maximize the amount of solar radiation captured by your solar panel, you will need to adopt the best orientation possible. You know solar radiation and the level of sunshine depend on several factors. Thus, to maximize the use of your solar panel, you can position it differently depending on the season for use (these values ​​will obviously vary according to the latitudes where you will be moving):

  • In spring: the ideal inclination of the solar panel will be 45°.
  • In summer: the optimal inclination of the solar panel will be 20°.
  • In autumn/winter: it will be advisable to orient your solar panel at an angle of 60° because the sun will be lower in relation to the horizon.

Best Portable Solar Panels: Selection Criteria

To find the right portable solar panel for your needs, follow our buying guide.

Type of Solar Panel

As we saw in the introduction to this guide, there are several types of solar panels on the market:

  • Classic solar panel: A classic solar panel isn’t equipped with an integrated battery. This type of solar panel is made up of several sections (most of the time), which allows the module to fold back on itself for easy storage. Its operation is very simple: when exposed to the sun, it will supply electricity to the device connected to it (smartphone, camera, computer, etc.) and will no longer supply it when the sky is overcast.
  • Solar panel with battery/solar charger: this module consists of very compact solar panels connected to a power bank-type battery which will be responsible for storing the energy captured by the photovoltaic cells. Often it is equipped with a USB socket, so it will be possible to recharge the power bank without having to expose it to the rays of the sun, on a power outlet. The accumulation of energy on these devices is longer than on conventional solar panels.
  • Flexible solar panels: Flexible solar panel is made up of monocrystalline cells (like their “classic” rigid counterparts). These solar panels adapt more easily to uneven surfaces and will operate in the same way as a conventional rigid solar panel. The only difference is that their efficiency will generally be lower depending on the technology used (CIGS or amorphous silicon).

Rated Power

To benefit from a fast charging speed for your electronic devices using a portable solar panel, the power of the device will be an essential point. The power is expressed in Watt (W). The higher it is, the faster the devices will recharge.

However, this aspect obviously remains a theoretical value to be qualified with the sunshine conditions when you use it. To compensate for any eventuality and weather hazards, there are also hybrid solar panels (benefit from batteries), which allow the devices to be recharged with the solar panels or directly from an electrical outlet.

The Solar Yield

The solar yield is expressed as a percentage and corresponds to the number of photons captured by the panels which will be transformed into electricity. The average solar yield of a solar panel is around 18% (which therefore means that 18% of the particles present in the sun’s rays will be captured by the panels).

We therefore advise you to choose a panel whose solar efficiency is equivalent to or greater than 18%. Other solar charging devices, such as USB solar chargers, may have higher efficiency, around 22-23%.

Integrated Battery for Hybrid Models

The models of hybrid solar panels, equipped with an integrated battery, will allow you to store energy to deal with weather conditions that are not conducive to sunshine (showers, clouds, etc.). Thanks to the battery, you can recharge an electrical device such as a power bank, several times.

These models of solar panels will also make it possible to regulate the flow of electricity under load to avoid any damage to the battery of the latter by guaranteeing a stable and constant flow. You can find models equipped with an integrated battery or a separate battery, usable without the solar panel as a power bank.

Finally, there are several types of batteries for hybrid solar panels:

  • NiMH (Nickel Metal Hybrid) batteries: these correspond to AA or AAA-type rechargeable batteries and will be practical options for charging the batteries of a headlamp or a small device equipped with batteries.
  • Lithium-ion and lithium-polymer (Li-Ion) batteries: These are the most common type of batteries for portable batteries that are also found in electronic devices equipped with batteries (smartphones, cameras, etc.).
  • Lead-acid batteries: rarer, they are heavier and more imposing than lithium-ion batteries but have better performance and increased power capacity.

Portable solar panels can also be equipped with external batteries

Storage Capacity for Battery Models

It corresponds to the number of charges that the battery will be able to store for later recharging use before being, in turn, recharged. This data is often indicated on the device (expressed in milliampere-hours = mAh or ampere-hours = Ah). You can find another value, the Watt-hours (Wh), which can easily be converted into mAh: (Wh/Volts) x 1000 = mAh.

Be aware that a transfer of energy from one (charging) battery to another (that of the device to be recharged) is never 100% electrically efficient. Therefore, to charge your device, you will need to choose a battery with sufficient storage capacity and a sufficient output voltage. It all depends on the type of device you want to charge.

Output Power for Battery Models

The output power of the charger, expressed in volts (V), must be equal to the input voltage of the battery of your electronic device. If it is lower, you risk draining the battery of the device instead of charging it.

The vast majority of solar chargers are capable of charging small electronic devices (using a USB cable) with an output power of 5V. On the other hand, solar chargers capable of charging more greedy devices requiring a DC power input (like laptops) will need a much larger output capacity, between 12 and 24V.


The connectors will depend on the type of solar panel chosen and the use you are going to make of it:

  • In the case of a solar panel with battery (integrated or separate): all the connectors necessary for charging between the solar panel and the battery will be included with the latter.
  • In the case of a single solar panel: it will be necessary to check which output connector the solar panel has and also its ability to charge a device directly or not (which the manufacturer recommends). In this case, you will find several types of connectors, which may be useful depending on your use and the devices you want to connect again: USB port, connector, DC output, etc.

Finally, be sure to choose a solar panel with Intelligent Charging, which prevents any risk of overvoltage during use.

Surface and Dimensions (Height and Weight)

There are many portable solar panels in different formats: from the large solar panel to be placed on the ground, to the small folding solar panel which will not be larger than a wallet. The larger a solar panel, the more it will be able to capture the sun’s rays and therefore produce electricity. A small panel will be easier to transport and store but will take longer to charge a battery.

Thus, the ideal surface of a solar panel will depend on your uses and your expectations. If you want to hike in the mountains in winter or in difficult sunlight conditions, choose a solar panel with a large area. On the contrary, if you want to go hiking with a minimum of equipment in the summer, choose a solar panel of small dimensions and as light as possible.

Brands to Consider

There are many manufacturers who offer portable solar panels suitable for all situations. However, not all of them are specialized in niche practices. The brands recommended by satisfied users are Powertec, SunSlice, Anker, RavPower, ECO-WORTHY, Goal Zero, Westinghouse and PowerTraveler.

The Prices

Depending on the type of portable solar panel, its manufacturer, power and its functionalities, you can find entry-level models for around $20 while most high-end models will exceed $100.
