How Do Solar Car Battery Chargers Work?
Solar car battery chargers are portable devices that use sunlight as the source of power. These chargers have a solar panel that collects sun light to produce electric current that is passed on to the battery. These chargers produce DC current that can be transmitted into the battery through clips.
The charger can be placed on the dashboard or roof of your car to collect solar power. Regardless of where you place it, make sure that enough sunlight falls on the panel to produce electricity.
Are Battery Chargers Waterproof?
Most chargers are designed to be placed outdoors so the manufacturers make sure that they are water proof in case of sudden rain.
However, the panels are not submersible in water. A current runs through the wires so try to keep them away from too much water.
Can I Use Solar Chargers on Any Vehicle?
Before you use a solar battery charger, make sure that it is compatible with your vehicle’s battery. Generally, car batteries take a 12v input and most solar battery chargers are designed to produce 12v current.
However, if your vehicle’s battery has a different input, make sure to get a charger that matches your vehicle’s specifications.
How Long Does It Take to Charge the Battery?
The answer to this question depends on multiple factors. Batteries with bigger capacity take longer to charge then smaller batteries.
If your battery has less than half the charge, then it would take some time to charge it compared to when it is slightly empty.
What is Charger Efficiency?
Solar power panels are measured through efficiency. An efficiency of 10% means that the panel can convert 10% of sunlight into electric power while the rest is wasted.
The technology is still under development. So an efficiency of 20% to 30% is considered the best right now.
For most solar-powered battery charger, you’ll want to find one that has an efficiency rating of at least 20%. This efficiency rating means two things.
First, you don’t have to put the charger directly into the sunlight to generate power. Even reflected light can give you a good result and help charge your car battery.
Second, you will be able to charge your car even in late autumn and early spring, or on cloudy days.
Solar car battery chargers are becoming a norm for people. They are portable, versatile and environmentally friendly.
When buying one for yourself, just think through a few key factors like efficiency, voltage, wattage, and whether they will work for your vehicle or not. Keep in mind that most chargers are designed for battery maintenance so they will not work with a dead battery.
