How to Choose The Best Solar Charger For Backpacking
Opting for a high-quality and suitable backpacking solar charger seems to be a challenging task for those who have limited understanding about this specific type of product.
Consequently, today I jot down several factors that you should take into consideration carefully before making a purchase. Hope you found it helpful. Now, let’s jump in.
Type of solar panels
Currently, there are 3 types of solar panels: monocrystalline, polycrystalline, and thin-film panels.
- Monocrystalline panels: They possess the best quality, so their prices aren’t as wallet-friendly as the rest. In detail, operating well in high-temperature situations and earning a 20-percent efficiency rate are the two most impressive advantages of this type of panel.
- Polycrystalline panels: Actually, polycrystalline panels only perform slightly less competently than monocrystalline panels in high-temperature circumstances. While monocrystalline panels are made from crystal, poly ones are made from many. Due to their fairly good performance and budget-friendly price, polycrystalline panels are always the top of the choice of all backpackers.
- Thin-film panels: Compared to their crystalline counterparts, thin film panels seem to be less convenient and less efficient. They only yield a low efficient rate (approximately from 7 to 13 percent). Also, they need a larger area of coverage. However, they are the cheapest pick.
Just think carefully and pick up the panel fit you most.
This is an indicator showing the maximum quantity of watts you could draw from the charger at any time. You should consider how much watts to fit your desire; you may need a charger with a large inverter rating.
Please be noted that inverter size doesn’t decide the solar charger's capabilities. For instance, a 1500W inverter won’t be perfect if it uses a 450Wh battery. At least a 1.5:1 ratio (watt-hours/inverter rating) is considered to be the best ratio of good-quality solar generators.
To conclude, if all you need is charging small devices such as smartphones, tablets or handy small-sized fan, a 200Wh charger is appropriate for you.
It is one of the most pivotal factors which decide mainly on whether to buy a certain solar charger or not. The charging capacity differs according to the battery’s type and size. The distinct device performs differently.
And the internal system is the key point which determines the relationship between the battery and the panel. There are a series of solar chargers allowing you to charge your technological appliances while the solar charger’s battery is charging.
It is the truth that price is always the first thought popping up on your mind when it comes to making a purchase. A couple of years ago, the prices of solar chargers were a bit high, so people rarely bought one.
But now, due to the fast-paced development of technology and the severe competition between solar charger providers, the prices of solar chargers have decreased considerably.
Currently, there is a series of money-saving options available for you to pick up. Plus, eco-friendly solar chargers are becoming a hot trend in the current market now. In case you have a sufficient budget on purchasing a high-end solar charger, just pick up the environment-friendly solar chargers as they are always the best.
It is a highly crucial factor when it comes to opting for a charger. If the charger isn’t compatible with your gadgets, then it is injudicious when buying them. As a result, please kindly check whether your devices’ model, voltage, size, and power are compatible with the solar charger’s specifications or not.
The warranty duration somehow could represent the durability and reliability of a certain product. Hence, the longer the warranty duration is, the greater your charger is. Don’t forget to ask the salesman clearly about the warranty duration and guarantee program as you could need it someday.
Things to avoid when picking up a solar panel charger
- Avoid purchasing chargers which have the battery and solar panels set up in the same unit. As it will diminish your battery’s lifespan due to heat. Naturally, batteries hate heat.
- For the sake of easy replacement, you are better off buying individual parts. Hence, when a certain part is spoiled, you could easily repair or replace it as easy as pie.
- Be careful of the snake-oil pitch as various companies are making use of this stuff and convincing their customers that their solar chargers are the best. Stay away from throwing your big money into poor-quality solar generators.
- In general, solar chargers with built-in panels are likely to be engineered in a way which can’t be repaired. Hence, stay away from built-in solar panels.
Frequently Asked Questions
1. How long does it take to fully charge with solar panels?
In fact, it depends on the types of the battery. For a 1500mAh battery charge, in an ideal condition, it could take up to 4 hours to fully charge. For degraded batteries, it may take much longer to completely charge (6 hours probably).
2. What is the lifespan of the solar panel?
It is the most frequently asked question I have received, and most buyers care about. Although all solar panel providers go out of their way and put a lot of time and effort into making the solar panels vigorous. However, nothing could stand the severe test of the time. And solar panel either.
Actually, the lifespan of the solar panel vastly depends on what type it is. In general, standard and Trina solar are two types of solar panels having the longest lifespan. The maximum lifespan of a standard solar panel is approximately 25 year.
In order to extend your solar panels' age, you should keep it in safe places, prevent it against physical damage such as rain, wind. The more bad weather the panel is exposed to, the quicker they will degrade. Plus, regular cleaning and maintenance are also crucial.
3. Are all solar chargers for backpacking weather/waterproof?
Sadly no. Not all solar chargers feature weatherproof or waterproof. Hence, when making a purchase, don’t forget to ask the salesman about the waterproof and weatherproof features.
If it’s possible, I highly recommend you to buy a weather/waterproof solar charger as it tends to be more sturdy, durable and robust.
4. Can you start charging devices before the solar panel is fully charged?
Yes, you can. However, if you are keeping charging devices before the solar panel is fully charged, your solar panel could be gradually worn-out. And I bet you don’t like this matter happen, so remember to charge other gadgets only when your panel is 100% charged.
