Solar Battery Charger

Sometimes, the excessive energy that solar panels produce is not taken by the grid appliances for consumption. The job of solar battery chargers is to transfer that extra energy to batteries for later production. You can often control the charge of battery chargers to form efficient charging patterns with your panels. Scaling the charge according to the production capability of your solar panels will help the whole system. Many solar battery chargers work automatically according to the production rates to ensure the panel's efficiency remains at its peak at all times.

Solar battery chargers have a lot of significant advantages which make them desirable in any solar panel system-

• Solar battery chargers automatically transfer a particular amount of charge to the battery for storage.
• Solar battery chargers can help you preserve energy for moments when you need it the most. 
• Solar battery chargers are primarily automatic, cutting out the need for human interference. 
• Solar battery chargers increase your panels' efficiency while keeping your battery in a healthy state for a long time.

Solar battery chargers are not simple devices but have many complex parts that work together to get the job done. Some of the essential components of solar battery chargers are-

• Voltage regulator- The voltage regulators of solar battery chargers control how much charge goes to the battery. The circuit of solar battery chargers has voltage regulators to provide a stable balance to the whole apparatus. Charge controllers also come with a failsafe to prevent any excessive flow of current through the charger. 

• Solar panel- The solar panel converts solar energy falling on the charger into electricity. The efficiency of every solar panel depends upon its size and how the silicon crystals are in arrangement. Solar panels come in many types, but most solar chargers have thin-film solar panels. Thin-film panels are easy to place almost anywhere because of their lightweight and flexible nature. Thin-film panels are also adequate for charging small devices which do not require a lot of power. 

• Battery- An extra lithium battery in the charger helps store excess electricity in production for later use. When solar energy is not accessible, the battery will provide all the devices with a consistent power supply. Solar panel charger batteries are usually inexpensive because they do not charge any heavy-duty instruments. However, power plant chargers have large batteries that store an enormous amount of power for future use. 

Solar battery chargers provide stable electricity if you efficiently use them when essential. This renewable energy is necessary in a world where non-renewable energy is running out incredibly fast. 

Advantages- 

• Solar battery chargers provide a stable source of renewable energy for future use.
• Solar battery chargers can make the whole solar panel system more stable by managing excess energy in production. 
• Solar battery chargers are essential in most solar panel systems as the panels will produce extra energy that has nowhere to go.
• Solar battery charger circuits also forward electricity to an appliance where it needs to go efficiently. 

Disadvantages-

• Solar battery chargers have charge limitations to keep the whole system stable.
• Solar battery chargers are not very stable at high temperatures.
• Solar battery chargers are a part of solar panels, which takes damage to efficiency the fastest.
• Solar battery chargers are usually not very good in harsh weather situations. 

Solar battery chargers have several parts which work together to convert solar energy into electrical energy. They are-

• Voltage regulator
• LED lights
• Resistors of variable resistance
• Schottky diode
• Diode
• Solar panel
• Battery (5v – 14V)

The prearrangement of the above parts in the panel depends on the panels' power rating and size. If the panel is large, the battery, voltage regulators, resistors, and diodes will be of larger capacity. The size difference and quality of parts initially define the price of your solar panel chargers.
