Factors to Consider When Choosing the Best Solar Car Battery Chargers
1. Types of Solar Battery Chargers
There are two primary types of solar chargers; solar car battery maintainers and solar battery chargers.
- Solar Battery Maintainer
These products are designed to maintain the charge in your car battery. They keep the battery power at ideal levels to ensure the battery doesn't lose charge. This helps to lengthen the life span of the car battery, which is the first reason people invest in them.
Automotive batteries naturally discharge when they are not in use. So, if you park your car for the season, you'll need to get a battery maintainer. Otherwise, all you'll have by the time you use your car again is a dead battery.
- Solar Car Battery Charger
A solar car charger is a device used to power up batteries. They are larger and more powerful in comparison to maintainers, and they can recharge batteries to full capacity. These products are great for meeting your battery charging needs when you are far from a power source.
2. Efficiency
The efficiency of solar chargers is a key consideration because they are meant to assist in cutting energy consumption costs. However, these products have different efficiency ratings. The most suitable options are the ones that can still harness solar power even when there isn't direct light from the sun.
These units are designed to power batteries even in cloudy and stormy weather. Unfortunately, they won't generate as much power in cloudy weather as they do when it's sunny. However, they can help keep costs low by providing the power you need despite taking longer than usual to supply it.
3. Power
Car batteries vary in power requirements just as they do in other factors. The amount of power your batteries need should be a determinant of the battery charger you select. This is because a solar battery charger with a low power range will need a lot of time to charge your batteries than one with higher power output.
Unfortunately, the chargers with more power also carry a higher chance of overcharging issues. So, if you'd rather avoid the risk, you can go for a unit with lower power even though you'll have to wait for long before your batteries are full.
4. Reverse Charge Blocking Diode
Since car batteries tend to lose charge over time, it's crucial to look for a charger that can prevent the loss of power. One of the features to keep an eye out for is a Solar Charge Controller, which controls the flow of charge to and from the batteries.
When the charger has a charge blocking diode, you can rest easy since it'll prevent the battery from losing power. This will help preserve the performance of your batteries and will save you a lot of time.
5. Price
Solar battery chargers range in prices depending on the materials used to make them and the specific brand. Some are more affordable than others, but the most expensive isn't necessarily the best fit for you. There are some excellent solar-powered chargers that have a price tag that's below $40. These are lightweight and have a compact design which is why they are affordable.
Those above $40 are high-performance options with various accessories and features that make them more convenient to buy. Some of the additions they could have include overcharging protection, high efficiency, and weatherproofing capabilities. They are the best option for long term charging and maintenance.
6. Size and Weight
Another factor to keep in mind is the size and weight of the unit. Most people get solar panel chargers to supply power as they set out for road trips or camping. This means that it'll be necessary to carry them along the journey. If the unit is bulky and heavy, handling it could be tricky.
You should go for a light enough unit to handle without the hassle and compact enough to store without having to leave some things behind. Nevertheless, if you have abundant space and energy, there's nothing wrong with taking a large solar battery charger. Remember that it's possible to have a powerful but lightweight solar charger.
7. Weatherproofing
The last thing you should look for in the best solar car battery charger is weatherproofing and water resistance. Since solar battery chargers work by converting light energy into electricity, they'll need to be outside the car to access direct sunlight. As such, your solar car battery charger will be exposed to the elements as it powers up.
Factors like rainfall, snow, or hail can easily affect the performance and longevity of solar panels. That is why it's crucial that they have some form of protection from extreme conditions. This means that you should opt for a unit that features weatherproof and waterproof capabilities to ensure it works for as long as possible without getting damaged.
