Picking the best battery for your solar energy system is not difficult. In fact, it is relatively easy. But there are many factors that you need to consider when buying a battery. This is especially true if you are going to use the battery to power a home energy system. So, let us focus on the three most important points to consider in picking the best battery for your solar panel system.

3 Important Factors You Need to Consider

How to pick the best battery for your solar panel system? There are many factors that will determine the answer to this question.

The Size

The most important one is the size of the battery. There is no question that the size of the battery determines how much energy it can supply to your home solar energy system. This means that the battery size and the number of cells in the battery will directly affect the energy output and the number of amps that the system can pull from the battery. This is the first thing that you need to keep in mind when learning how to pick the best battery for your solar cell bank.

The Level of Charge

Another factor in learning how to pick the best battery for your solar cell bank is the level of charge that the battery is capable of maintaining. The higher the level of charge, the longer the battery will last. And the longer the battery lasts the more money you save because you do not have to buy new batteries as often. The battery should be able to maintain at least 80% of its charge at all times.

The Chemistry

The next factor that you must be aware of is the chemistry of the battery. The chemistry affects the way the battery charges and discharges. There are three common chemical compositions of rechargeable batteries. These are lithium metal, nickel-metal hydride, and lithium ion. You will need to learn the differences between these so that you can better choose the battery for your needs.

Key Components of the Best Battery for Solar Power System

The Amount of Voltage It Can Handle

Another key component to consider to pick the best battery for your solar cell bank is the amount of voltage the battery can handle. This is measured in volts. The higher the voltage of the battery the more power it can deliver to your solar power system. It also means the battery can sustain longer before having to be replaced. Be careful though, as high-voltage batteries can be very expensive.

How much amp-hours the battery can handle is also important. Amps is the unit of measurement for amps. You will want the amps for your battery bank to be in the mid-level. This means the battery can handle at least sixty amps. If the battery can only handle forty amps then you need to find another type. Find the best battery for your solar power system by keeping this in mind.

The Size of the Cell-Pool for Storage

You need to take into account the size of the cell-pool you will be using for storing energy. This is the maximum amount of amps the battery can handle for an eight-hour day. This is the most important consideration when determining the best battery for your solar cell-bank. If the battery can't handle the number of amps you need, then it isn't going to be able to do its job. Find the next biggest size after the amps for the best battery for your solar system.

The Three Best Types of Batteries for Solar Systems

There are many factors to consider when deciding what the best types of batteries for solar systems. One of the most important factors is to determine what the size of the system you want to use will be and how much power you need. The battery size is important because the amount of storage you will need will depend on the size of the battery and the amount of power it can store. The size of the battery also determines how much you will have to pay to have a backup battery system. All of these factors to consider when deciding the best types of batteries for solar systems. Here are three best types of batteries you need to consider:

1. Lead Acid Batteries

Lead acid batteries have the potential to be the cleanest and the safest batteries for the vehicle. But before buying the lead-acid battery, the buyer must know the advantages and the disadvantages of the same. It should be checked that the battery is not free and the lead-acid level does not get depleted before the discharge. Leakage of lead can occur due to the moving parts of the battery such as the terminals and the leads. Once the battery has the capacity to discharge the lead acid will form the liquid which will harden and the battery will lose the capacity to charge and the battery will be useless.

Lead Acid Batteries

Lead acid batteries are the commonly used form of battery in the photovoltaic systems today. The lead is very porous to facilitate the chemical bonding and the dissolution of the lead. The main positive electrode is made of pure lead; the negative one is also made of the common graphite. Both the electrodes are submerged in an electrolytic bath of sulfuric acid, magnesium sulfate, and water. These batteries have the ability to accept the high energy densities and the high temperatures; this is the major reason behind the efficiency and the power of the same.

Lead acid batteries have the disadvantage of the water loss at the stage of charging. This is the major factor which could ruin the battery system. The water loss could occur due to the influence of the cold weather, the moisture content of the soil and the oxidation of the rusting metals in the battery. The water must be replaced to prevent the loss of the important oxygen gas. To prevent the water loss in the temperature of the vehicle must be kept low; the exterior temperature of the car must be less than the battery temperature to prevent the water loss. This is the major disadvantage of the lead-acid batteries.

2. Saltwater Batteries

Saltwater batteries are the most efficient when it comes to the cost of storage, but the disadvantages can be a downfall as well. While the benefits of a saltwater battery are many, the disadvantages can make it difficult to use and store. The disadvantages of the saltwater batteries can be found in the typical saltwater battery specification sheet. If you're looking for the typical specifications of a saltwater battery then you'll find the usual lithium-based salt and metallic ion batteries are the typical sort.

Saltwater batteries have several distinct advantages due to their chemical makeup. The saltwater in the cell means there is virtually no fire risk with saltwater batteries, as the cell would be considered a volatile material if exposed to fire. Also, the salt water actually allows the battery to have a lower energy density than the typical lithium-based battery. This lower energy density is actually important from the point of view of the energy conversion efficiency of the battery.

Due to the lower energy density of the saltwater batteries, they don't last as long as the typical lithium-ion or standard lithium-based battery options. The life of the saltwater batteries also depends on the usage and the state of the environment, the battery is being operated in, as the battery won't function properly and the maximum usable life will be impacted by the weather. Additionally, saltwater batteries tend to have less usable storage power and have a shorter shelf life than the other battery options. As a result, the typical saltwater batteries are better suited for applications where the life of the battery isn't an issue such as the emergency grid up and running.

3. Lithium Batteries

There are many benefits that come with the lithium batteries for solar power system. But, they are the biggest drawback as well. The lithium metal is very expensive and the high price of the lithium batteries for solar power system makes the solar batteries a little unaffordable for the average Joe. But, the disadvantages of the lithium batteries are pretty much the same as the advantages.

One disadvantage of the lithium batteries for solar power system is the high temperature that the lithium metal must be put into. The lithium metal would require a special device to prevent the temperature. The biggest advantage is the price. But, the price still remains high. Some people who use the lithium batteries for solar power system have expressed concern about the high price and the long shelf life of the batteries.

In some cases, the lithium batteries for solar power system has actually lead to the production of the cadmium metal. This is because the cadmium metal was being used to create the battery. This was the first time the cadmium metal had been used in the battery. But, the lithium batteries for solar power system is not entirely safe. So, you should make sure that the lithium batteries for solar power system that you buy are the real thing.

Key Components of the Batteries You Need to Compare

Why is it important to compare the components of the different batteries for solar power system? To begin with, the right choice will help the customer get the maximum worth of the investment. Secondly the right choice will also ensure the best performance in the long run. The three different components that should be compared are the battery, the charger, and the inverter. If you compare the battery with the others you will get the clear idea as to the quality of the product.

To compare the components of the batteries for solar system the three most important are the cells, the battery itself and the chargers. Cell size is the first factor that affects the performance. The cell must be the right size. There is a lot of variation in the size, so the user must know the size. This means the user must buy the appropriate battery to the appropriate size. When the cells are the same as the performance is the same but the performance can be better or worse if the cells are the wrong size.

The Size of the Battery

You should first know the size of the battery that is required for the solar system. By measuring the depth of discharge of the battery, you can easily find the size of the battery. The depth of discharge indicates the amount of energy that the battery can deliver to the electrical device. Therefore the battery should have the capacity to deliver maximum wattage even during the peak usage.

The Manufacturer

The second component to be compared is the manufacturer of the battery. It is important to know the manufacturer because the product you purchase may be a replacement or an original product. Replacements can be expensive. Original products may have some flaws, which the buyer may not be aware of. However the warranty of the battery still remains intact.

It is important to know the manufacturer of the battery. It is the manufacturer that understands the characteristics of the cell so it is the manufacturer that should be used. The capacity of the cell is the factor that determines the performance and the quality. It is the capacity that the manufacturers use in determining the battery life and the warranty. When the battery is bought, it should include the capacity of the cell that is included in the order of the size of the battery.

The Efficiency

The third component to be compared is the efficiency of the battery. This can be determined by the cycle count, the maximum power points, the life time and the temperature sensitivity. The cycle count indicates the number of times the battery can be charged and discharged. The maximum power point is the maximum voltage the battery can attain. Temperature sensitivity indicates the ability of the battery to tolerate different temperatures. The efficiency of the battery greatly affects the performance of the cell.

The Life and Warranty

The quality is the factor that determines the performance. The more the quality the higher the performance and the longer the battery life. Thus the battery life and warranty of batteries for solar systems must be the same. If the battery life and the warranty are the same the user will get the battery at the best possible price. But if the battery life and the warranty are different the user will get the battery at the lowest possible price but the quality might be the lowest.

The Charging Converter

The charge converter is the next most important component. It should be the right charge converter. A lot of the rechargeable batteries do not have the correct charge converter. They may have the wrong voltage or the wrong output. The user must check the specifications of the battery very carefully and the charger must be the correct one.

What Happens When Your Solar Batteries Start to Die?

what happens when your solar batteries start to die

We all have gone through the experience of what happens when your solar batteries start to die. It can be a real shock, the sudden inability to charge the batteries that we depend on to power our lives and everything in-between. Many of us are quick to jump to conclusion and figure out the problem is in the battery or the connection between the battery and the inverter. Others prefer to take the battery for a little test drive to see if it has indeed died. If you take care of the battery while it is under warranty however, the battery will often come back to life and begin charging again.

There are other signs that may indicate that your battery is about to die. The indicators are the same that you may see when your other battery batteries at your home are starting to die out. They include things like an odd smell, not getting as much power as it used to, and slowly losing the ability to hold a charge. Once your battery is starting to go flat, you need to know how to restore or recondition it.

When you know how to restore or recondition batteries, you will find that when your battery does charge again, it will charge a lot faster and last longer than before. You will also save money on your monthly electric bill because you will be able to store a lot more energy than you were using before. Knowing what happens when your solar batteries start to die, is the first step in taking charge of your electrical needs.


Make sure that the battery you choose has good corrosion and rust protection. A battery with good corrosion protection will be able to hold up to the sun longer and help the battery store the energy that it absorbs. This way the battery will continue to function for many years to come. Use the information here to pick the best battery for your solar power system.
