Solar Chargers Common Knowledge

How Backpack Solar Chargers Work?

The solar chargers mentioned above operate by absorbing sunlight using solar panels, converted into electric power to charge your electronic devices.

The solar cells in the solar panels are once responsible for converting solar energy to electric energy. Some of the portable solar chargers come with one or more panels that contain tiny silicon photovoltaic cells.

When the silicon solar panel is hit by direct sunlight, a reaction occurs, causing the loss of protons.

These protons are once responsible for producing electric power. The electric power that has been converted into electric power is then transferred to your USB charger, charging your electronic devices. 

Some of the portable chargers mentioned in the article have lithium batteries that can store solar energy. The sored solar energy can then be used to charge your devices at night when there is no sunlight. That makes the solar chargers efficient and compatible for easy use at any time of the day.

Types of Solar Panels

There are many different types and models of solar panels in the market today, and before you decide on one of them, you should know which one is the best, durable, and more efficient.

You will need to do a bit of research and know the ones existing on the market and how they operate. The main differences in solar panels are design, durability, weight, and size. Let us look at the three solar panels that exist on the market today.

Monocrystalline Solar Panels

These solar panels are characterized by dark colors and have round edges. They are made with monocrystalline silicon, making the solar panel more efficient and reaching rates of 20%.

These types of solar panels can work well under harsh temperatures making the panels durable and long-lasting. They are the best for power conversion, which makes them expensive compared to other solar panels.

Monocrystalline Solar Panels are the most common panels in the market and have been like that for years. They can work well under cloudy, moist, and frost conditions.

Polycrystalline Solar Panels

These solar panels have low efficiency in solar panels, and they are made with melting raw silicon. They are the cheapest in the market and have an efficiency of 15%. Polycrystalline Solar Panels are not exceptionally durable but will still serve you well.

You will need to expose them to direct sunlight for better efficiency and operation. If you want to go solar and do not want anything expensive, the Polycrystalline Solar Panels is the best option.

They are massive compared to other solar panels. Even though they have low efficiency, they are more modern compared to the monocrystalline solar panels.

Amorphous Silicon Solar Panel – Thin Film

These solar panels are for people looking for a cheaper option. They are made with thin-film solar cells that makes them smaller. Amorphous Silicon Solar Panel is made by placing silicon, cadmium, and copper on their base.

Considering that they are easy to make and cheap, they have a short lifespan. These solar panels are less sensitive to temperature compared to other solar panels.

Their efficiency rate is 7 to 10% hence cannot work well for someone who needs a fast and more efficient solar panel.  Amorphous Silicon Solar panels are not meant to last for long and are good for short term projects.

Concentrated Photovoltaic Cell

These solar panels have a multi-junction, which gives them an efficiency of 41%. Concentrated Photovoltaic Cells are more efficient, and that is due to their curved mirror surfaces, lens, and cooling system.

To get the highest efficiency, you will need to place the solar panel at a certain angle for better operations. Concentrated Photovoltaic Cell comes with a solar tracker that can follow the sun’s movement, and you will never miss out on any rays from the sun.

Final Thoughts

Solar Charger

Solar panel development is growing every day, which means more and more panels are being produced daily. It has now become easier to buy portable solar chargers if you are frequently on the move. Portable solar chargers come in different designs, efficiency rates, and prices too.

They are entirely safe to use anywhere anytime if you recharge them during the day when there is sufficient sunlight. Before buying a solar panel, you will need to check for the following things first.

Power output of the portable solar charger

Almost all phones come with a 5W that means if you want to charge it faster and most safely, you will need to get a portable solar charger with more than 20W.

A solar charger with 20W will be able to charge your smartphone quickly and still protect it from overcharging and short-circuits. Different companies manufacture such portable solar panels so just do your research well before buying one.

Look at the charging speed of the solar charger

Some solar chargers have low speeds, and others have high speeds, and it will all depend on how fast you want your devices to be charged.

If you are the kind of person who is always out on adventures, it would be best if you get a portable solar charger with a fast charge. It will save you time and money, and your devices will get full quickly. Even though they might be expensive, it is always a good investment in the long run.

Check for the size and weight of the solar charger

Different solar chargers have different sizes and weights. If you like outdoor adventures, a portable solar charger that is light but amazingly effective will be a good idea. Hikers and campers do not always like heavy things that hinder their freedom in the wild.

So, having a solar charger, which is light, will be a good idea. Always select solar chargers with high efficiency and still light at the same time. They are available in the market and will serve all your needs without compromising.

In this article, we have given you some of the best ultralight portable solar panels that are available, and the next time you go shopping for your adventure kits, do not forget to get yourself one. They are affordable, effective, and easy to carry around.
