How Backpacking Solar Chargers Work

All the above solar chargers absorb sunlight and convert it to produce electric power.

They all contain one or more solar panels that contain small silicon photovoltaic cells.

When the sun hits the silicon panels, a reaction occurs that causes the loss of protons.

These protons produce electric power.

This electric power is then transmitted through the USB to charge up your device.

Some of the models in this article have a lithium battery that helps to store the energy.

This allows the owners to charge their devices even when there is no sunlight.

Types of Solar Panels

There are many different models and makes of solar panels, so before buying a solar charger, be equipped with knowledge about the types of solar panels and how they work.

The major differences between the solar panels are size, weight, durability, and design.

I will discuss the 3 main types

Monocrystalline Solar Panels

They’re made of monocrystalline silicon.

They’re characterized by a dark color look and round edges.

Due to their silicon’s purity, their efficiency rate can reach 20%.

The silicon also makes them durable against high temperatures.

They have a high power output and that makes them expensive.

These types of solar panels are by far the most common and have been in the market for many years.

They have the best performance in cloudy weather.

Polycrystalline Solar Panels (pSi)

These solar panels are cheaper as they’re made from melting raw silicon.

They have a low-efficiency rate of 15%.

They’re also not durable especially when exposed to hot temperatures for a long period.

They’re ideal for those looking for a cheaper option.

They’re fairly heavy.

They’re more modern compared to monocrystalline panels.

Thin-film: Amorphous Silicon Solar Panels (A-Si)

They have thin-film solar cells and that makes them smaller.

It’s made by placing silicon, cadmium or copper on to a base; this makes them a cheaper option.

Considering that they’re easy to produce and are cheaper, they have a shorter lifespan

They’re less sensitive to high temperatures compared to other panels.

They have a 7 – 10% efficiency rate.

Concentrated PV Cell

Its panels are a multi-junction type with an efficiency of 41%.

They’re efficient due to their curved mirror surfaces, lenses and cooling system.

However, to reach their greatest efficiency, they’re required to face the sun at a specific angle.

To do this, they’re equipped with a solar tracker that follows the sun.

Final Thoughts

Due to the recent developments in solar technology, it’s now easier and cheaper to buy portable solar power chargers than it was before.

These products are completely safe and easy to use

When choosing the solar charger to buy, check the following:

  • Power output; a normal phone uses about 5 W so if you’re looking to charge more than a single device in less time go for a solar charger with an output of more than 20 W.
  • Charging speed; if you need to charge your devices often, I recommend you buy a fast charging solar charger.
  • Size and weight; larger panels need more space but are highly efficient and offer the best performance and smaller panels take more time to charge but take less space for storage.

I hope from the above varieties of portable solar chargers, you get to choose one that best meets your interest and specification to carry around with you while enjoying your outdoor activities.
