These solar panels are versatile and eco-friendly solutions for obtaining power away from fixed energy sources. It is possible by considering various factors like the ability to withdraw power when you’re off the grid, and fewer materials during the manufacturing process, which reduces the production cost and carbon footprint. Also, the working process to harness solar energy is identical to the traditional PV panels by having its pros and cons.

What are Portable Solar Panels?

Portable solar panels are lightweight and highly reliable photovoltaic modules that are easy to install and transport from one place to another with minimal complications.

Unlike the traditional roof-mounted solar panels that are bulky and large, these portable variants are flexible and easy to assemble by possessing the exceptional feature of producing more energy even during the toughest weather conditions with fewer space requirements. Mainly, the waterproof feature makes it suitable for travelling and outdoor purposes.

Typically, Portable solar panels of 100W come in the size of 150 cm x 40 cm and produce power of 0.6–0.7 kilowatt-hours (kWh) per day. Whereas, a size greater than 300W with a size of 200 cm x 100 cm generates between 1.8– 2.1 kilowatt-hours (kWh) in a day.

Different types of portable solar panels include:

  • Foldable: These solar panels can be folded and kept in your bag while travelling to various locations having an efficiency of 21.5% to 23.55%. There are three types of foldable solar panels namely monocrystalline (single silicon crystal), polycrystalline (multiple crystalline silicon fragments) and thin film (made of amorphous silicon, CdTe and CIGS solar cells).
  • Briefcase: Similar to the properties of foldable solar panels, these modules come in a protective casing similar to a briefcase-like structure which is easy to carry and offers additional protection for the solar cells having an efficiency of 22%.
  • Rollable: These panels are made from thin film solar cells with high flexibility and an efficiency of 21% to 23% approximately.
  • Backpack: The thin film solar panels are integrated along with a travelling bag having an efficiency of 17 to 22% approximately and the actual power output varies according to the angle and intensity of sunlight, temperature, and condition of solar cells.

How Do Portable Solar Panels Work?

You can understand the working procedure of solar panels by knowing these components in detail:

  • Solar Panels consist of a collection of photovoltaic solar cells that release photons to generate electric fields when sunlight strikes the panels, known as the photovoltaic effect.
  • Charge Controllers regulate the voltage and current from solar panels that should pass through the battery to avoid overcharging.
  • Batteries receive the electric field through the metallic strips present on the solar panels to store energy and generate DC power.
  • An Inverter converts DC power to AC power by ensuring the smooth operation of your devices and appliances.
  • The Adapter Kit helps you charge your devices by connecting them to the system.

Although Portable solar panels can perform well on cloudy days, their efficiency is reduced. As a result, direct sunlight with high intensity becomes crucial for these solar panels to operate effectively and produce higher power output.

Several factors can influence the efficiency of Portable solar panels such as temperature, shading, latitude, reflection, maintenance, soiling (dirt and debris), sun radiance, etc. There is a lot more to know about solar panel efficiency. It will ultimately help you to choose the right solar panel.

Pros and Cons of Portable Solar Panels

Here are the advantages and limitations of portable solar panels tabulated below that help you to comprehend well and plan accordingly:

S.No Pros Cons
