Blocking Diode And Charge Controller

The most basic solar charger is simply a solar panel with wires to connect the positive and negative wires to the terminals on your battery. This system can work, but if anything goes wrong, youll quickly kill your battery. Two pieces of equipment blocking diodes and charge controllers help protect your battery from this potential damage.

Battery chargers larger than 5W typically need a charge controller to regulate the amount of electricity coming from the solar panels, so the solar panels dont overload the battery and damage it. Without a controller, any spike in electricity could fry your battery. While a handful of solar chargers come with the charge controller built-in, youll typically have to supply your own, which will knock you back about $10 to $20.

Youll also need to make sure your solar charger includes a small device called a blocking diode. These little pieces of equipment tacked onto the back of the solar panel allow electricity to flow from the solar panel to the battery, but not the other way around. Without a blocking diode, solar panels can actually drain electricity from the battery at night, leaving you with a dead battery in the morning.

Without a blocking diode, youd have to disconnect your solar charger from your battery every night kind of pain, right? Thankfully, most solar chargers already include a blocking diode, so you dont need to worry too much about that.

Solar Battery Chargers For Phones And Other Devices

Other than providing battery backup and support for transportation, solar chargers have become a popular option for consumer electronic devices like phones, tablets, computers and even televisions. In the case of solar phone chargers, there is a common contextual use wilderness hikes or camping trips often call for an off-grid charging solution and can provide good sunlight exposure.

When you consider that the majority of people sleep in a room with a window, these chargers can also act as a wall outlet substitute. A long USB cable can connect to the charger on the window sill and provide simple, grid-free charging. Some of these phone chargers are as cheap as $15 and many of them will also work for bigger devices you can find solar chargers for iPads or even laptops. However, these devices usually require more voltage and will cost in the $30-$50 price range.

Why Is My Solar Panel Not Charging My Battery

Tiny solar panels may not generate enough voltage to charge the battery. The power producer must produce a voltage higher than the battery itself to charge a battery successfully.

Car batteries dont have very high voltage, meaning you dont need large solar panels to charge them. But if your solar panel is for charging car batteries, thats not likely the problem. Its more likely that the problem is with loose connections or the batterys lack of a direct link.

A common problem is that the cigarette lighter the solar panel is plugged into does not have a direct connection to the car battery. You can test this quickly by seeing if it still works when the car is off.

If it doesnt, then it doesnt have a direct connection to the battery, it wont work if the car is off, and neither will any connections attached to it.

Q: How Long Should I Charge A Car Battery With A Solar Charger

Again, that is really going to depend on a lot of factors. The strength of the charger, the levels of sunlight in your area, the batteries size and current charge level. The good thing with solar chargers however is that they are pretty low powered thats why they are perfect as trickle, or maintenance, chargers. So dont leave them on permanently, as they have no overcharge protection. But its unlikely youll do major damage if you disconnect after a few hours in the sun. Also bear in mind that there are some models that come with charge indicators, and they will tell you the batteries current charge level. If you want peace of mind then, consider one of those models.

How Many Watts Does It Take To Charge A Battery With A Solar Panel

A solar panel output is measured in watts, and it can vary from product to product. Solar panels can generate up to 350 watts, but solar trickle chargers are very low power, just a few watts.

In order to charge a battery, you will need a panel to generate more voltage than the battery, and also have a minimum power rating, which is determined by your battery size.

The big factor affecting solar panel output, assuming its unshaded, is the irradiance which is a measure of the amount of the suns energy reaching the panel measured in kWh/m2/day or year.

Incidentally, this value if also known as the peak-sun-hours for a particular location and is used by solar installers to assess solar panel output energy in kWh.

Very low power solar panels can be left connected all the time

How Do Solar Powered Car Battery Trickle Chargers Work

AA Essentials 12V Solar

The best solar car battery charger will work using a charge controller that tells it when to stop distributing power.

  • Lets say you have a 10w panel charging a 12V car battery.
  • The solar panel produces about 17.6V of power, and
  • since that is higher than the batterys voltage, the battery will charge.

As the sun shines, the solar panel produces 10w every hour, converted into the battery, raising its voltage. Around 14.4V, the battery recognizes its complete and gets overcharged, dropping the voltage to 13.6V.

Without a charge controller, the panel continues to feed the battery electricity. Theoretically, the battery keeps dropping its voltage when it gets too high. But you still run the risk of overcharging your battery if the panel is left on.

This is when charge controllers come into play. They shut off the flow of electricity from the panel when it recognizes the battery is full, allowing them to stay hooked up to the battery without risk.

How Long Do They Take To Charge

Standard solar panels will take anywhere between 4 and 12 hours to receive a full charge.

The average for moderate to high wattage panels is between 6 and 8 hours of direct or mostly bright light charging hours.

During the winter, cloudy weather, or other lower light conditions, the charge time will be closer to the 12 or even 14-hour range.

Do Solar Battery Chargers Really Work What Type Do You Need

Yes! Solar battery chargers can fully charge your devices. The only thing is, if the battery has reached the end of its lifetime and needs to be replaced, a simple recharge won’t cut it.

They do take a longer time than gas powered or wall powered chargers but they are a great option for traveling or off-grid living.

Determine which one will work for your needs by answering the questions below:

1. What do I want to charge, something as big as a car or as small as a phone?

If you are looking for a charger for a specific purpose, like charging your car battery, then you can look strictly at solar car battery chargers. Typical 12v car batteries arent always the most reliable, especially if there is an accidental light in the car left on overnight or a car sits idle for months.

Once you determine the category of chargers you are looking at, i.e., automotive chargers, then you can pick between the chargers available. The size and type of the battery you need to charge will determine the size and amp power of the charger you need.

Solar powered battery chargers are a great way to add a charge to your 12-volt battery and act as a battery maintainer to expand their lifetime and practical use. Many of these batteries are known as trickle charge batteries because they produce a low current of electricity to charge batteries power banks.

2. How portable do I need the solar battery charger to be?

What Is The Difference Between A Battery Charger And A Battery Maintainer

On occasion, the phrases trickle charger maintainer and battery charger are used interchangeably. While both devices are designed to charge a battery, they are not the same.

A battery charger is designed to recharge a battery as rapidly and safely as possible. These devices do this by delivering a large amount of amperage and voltage to the battery so that you can get your equipment running quickly.

While using a battery charger is an effective way of cranking a piece of equipment that has a dead battery, these devices cannot be left plugged in all of the time. If you do, then the device will seriously diminish the capacity of your battery.

On the other hand, solar battery trickle chargers take a slow and steady approach to charging batteries. They deliver an incremental amount of electricity over several hours in order to recharge a battery or keep it from dying when not in use.

How Long Do I Leave A Solar Trickle Charger On

The amount of time that you should leave a solar trickle charger on depends on the size of the battery and the capacity of the solar panel.

If you have a small battery with minimal capacity, it will take less time for your device to charge. A larger battery with higher capacity will take longer to charge.

How Do Car Solar Battery Chargers Work

According to Lifewire.com, Solar battery chargers work by converting energy from the sun into electricity that can be stored in a battery. This is accomplished via a photovoltaic solar panel, which is the same basic technology used in residential and commercial settings to provide on-site power.

Solar battery chargers are nothing like solar panels on a house, though. Although the technology and science behind it are the same, solar battery chargers can only put out about 500 to 1,500 mA and thats on the higher side.

One of the best ways to use this charger is to provide more amperage at the beginning and ramp it down as the battery gets close to a full charge. High-quality chargers can do this automatically, while other chargers come with manual controls. It just depends on the charger you have.
