Portable Solar Battery

 
Solar batteries are the heart of solar panels as solar panels cannot function without these batteries. In addition to this, these batteries also have to meet the demands of unstable charging and discharging, grid energy and irregular full recharging. For this reason, a variety of portable solar batteries are available for you to choose. They are also affordable with respect to their installation. Let’s have a look at those battery types below;
 

1. Lead Acid

Lead acid batteries are one of the most used batteries in the renewable energy sector in order to store and directly use the electricity. It usually costs anywhere between $250-300, half the price of a standard lithium-ion battery (another type of battery). This type of battery is mostly used for providing backup power and solar systems for static situations. Chosen by many people for their solar panels, they find it very cost effective and highly functional, producing high currents.

These portable solar batteries have been around for years now, more specifically since the 1800s. Though the design has been changed since then, they still offer convenience to people. Furthermore, each cell of the battery produces 2 volts of energy and contains 2 electrodes of lead. When the battery is charged, the changes are seen in both the electrodes and electrolyte as well.
 

2. Lithium-ion

Lithium-ion batteries are one of the most common portable solar batteries to store technology, regardless of the application. Generally, these batteries cost between $750-950. Lithium-ion batteries are also used by people in solar panels but due to their high cost and old design, they are not the preferable option from many individuals. AGM and Vanadium (lead acid types) are making their way to the market like never before as they internally convert the oxygen and hydrogen and requiring little to no maintenance.

However, there is an advantage of buying lithium-ion batteries. They can typically deliver more cycles in their lifetime compared to lead acid batteries. Moreover, there is another benefit that a lithium-ion battery provides to its users; it is the high charge and discharge efficiencies which help produce more energy. In addition to producing more energy, they lose less capacity when inactive. This is quite helpful in solar installations, where energy is used occasionally.
 

3. Flow Batteries

Flow batteries are the latest form of storage batteries. According to research, the flow batteries are one of the most matured, advanced and contemporary technological batteries used until now. Also, sources report that it will be used by almost everyone by 2020. Furthermore, the cost of this portable solar battery will be $300 by 2024. According to research, the developers are creating ways to boost the power density even further, which will also pull down the cost.
 

Choose the Right Type of Battery

There are several factors in choosing the right form of battery. Here are the considerations that you must take into account;

• You must see the price of the battery. The price could either be greater or lower. A low price is good to pay only if it does not come at the expense of a short battery life, storage and quality. On the contrary, a high price is worth paying for an ever-lasting battery which will not give up on you.
• You also need to see the storage capacity of the battery. A portable solar battery must have sufficient space and storage capacity to store the energy in case of no sunshine.
• In addition to the price and the storage capacity of the battery, you also need to examine the cycle life of the battery. The cycle life can be determined by the process, materials, design and quality of the battery.

If you are planning to install a portable solar battery on your rooftop, then you will want to have any one of the types of batteries mentioned above. Now that you know about the costs and types of some common portable solar batteries, we hope you will be able to choose one that fits your requirements.
