Solar battery lifespan is one of the most important factors which manufacturers have to take into account to ensure that the solar batteries that they provide are robust. The solar batteries are deigned to resist cold and heat cycles.
Now, it is not possible for the solar batteries to be perfect and they will age. Due to this reason, owners should have sufficient knowledge about solar batteries so as to ensure that they can the right steps in order to prolong the lifespan of the batteries. One of the things that owners need to know is the type of battery in use. Lithium batteries have various advantages which consumers might not even know.
First, it important for people to what impacts the solar battery lifespan so as to ensure the lifespan is prolonged.
So What Impacts the Lifespan of Solar Batteries?
You must have wondered why there are some solar batteries which last longer as compared to others, even though the source of power is the same. Here are the 3 factors that you need to know about which impact the lifespan of solar batteries.
- Depth of Discharge
The DOD or depth of discharge is one of the most important things which solar battery owners should know about. It is the extent to which the solar battery would be used relative to the overall capacity that it has. It is normal for the batteries to degrade as they discharge and charge. The process decreases the capacity that they have for storing energy slowly.
- Cyclic Life
Next, another factor which owners need to know is the cycle life. The solar battery lifespan is determined primarily on the cycles that it can use. During normal use, a battery that is flooded would last for a minimum of 300 cycles and a maximum of 700 cycles.
- Temperature of the Depth of Discharge
The third thing which impacts the solar battery lifespan is the temperature of the depth of discharge. When batteries are stored in high temperatures, the chemical activity would be much higher. This leads to the capacity of the solar battery to decrease when the room temperature is too low. But, the lifecycle of the battery decrease with higher temperatures.
How to Prolong the Lifespan of Solar Batteries?
It doesn’t matter how good the design of the solar battery is, without proper maintenance, it would not last long. Follow the below steps to prolong the lifespan of the solar battery.
The Number of Batteries Needs to Be Controlled
Make sure to minimize the number of batteries that one uses in the bank. When more batteries are used, it would increase the resistance and connection that would only lead to uneven charging in the batteries.
Make Sure that Solar Batteries Do Not Remain Uncharged for a Long Period
The solar batteries are prone to damage when you do not charge them for a long period.
Equalize the Solar Batteries
The easiest way to prolong the lifespan of the solar battery is by equalizing it. It is the process in which the solar batteries are charged in a controlled way. It prevents uneven charging between batteries.
Use Solar Batteries of the Correct Type
Finally, it has already been recommended that lithium batteries should be used as they last for up to eight years. Replace the batteries on a timely basis. The lithium battery needs to be a rated voltage of 25.6 V or 12.8 V.
