Why Is The Solar System’s Battery Pack The Most Crucial Component
Contrary to popular belief, solar panels are not the most important component of a solar system. Actually, the battery pack is to blame. Many people got their start in the solar industry by investing in a few sun panels to power their typical lead-acid batteries. But getting your battery pack first can yield better outcomes.
Solar panels power the battery pack using solar energy. Your system wont produce electricity when its cloudy or the sun sets. Your battery pack is thus your only source of limited power. You have access to more power the bigger the battery pack is. You can charge your battery pack more quickly without using up more battery capacity if you have a sizable solar array.
What Are The Advantages Of Lithium Ion Solar Battery
There are many solid reasons behind using a Lithium ion Solar Battery rather than using a lead-acid battery because there are numerous benefits of this battery.
More Depth during Discharging
Depth of discharging rate of a battery defines that how much capacity of charges a battery can store and after storing how much time it will take to fully discharge the battery. The discharging depth of lithium ion battery is 95%, it means that lithium ion solar battery can release 95% of its stored power which is the highest of any battery that can provide.
Deep Cycle
Lithium-ion batteries are designed in such a way that the life span of these batteries is greater than lead-acid batteries used in solar power system, lithium sulphate used in these batteries provide greater lifecycle.
Lifespan of Lithium ion Solar Battery
If you use lead-acid battery because of its lower discharging depth rate it will last for almost 4 to 5 years because ions in the form of liquid are used to store the charges on positive and negative electrode.
On the other hand, Lithium ion Solar Battery will provide you the lifespan which is twice greater than the lead-acid battery with more charging and discharging lifecycle. There will be 5,000 lifecycles that you will get while using lithium-ion deep cycle battery specially designed for solar power system.
Greater Energy Density

Pro: Higher Depth Of Discharge
The DoD of a battery is the amount of the stored energy in the battery that can be used relative to its total capacity. Most batteries come with a recommended DoD to maintain the health of the battery.2
For example, the Tesla Powerwall II has a 100% depth of discharge , which theoretically means that you can use 100% of the energy in the battery before it has to be recharged .
Lithium-ion batteries have a high depth of discharge, meaning homeowners can use more stored energy without having to charge it as often. Lithium-ion batteries can handle discharging around 80% of their charge before needing to be refilled, as opposed to a lead-acid battery, which should only be run to 50% depth of discharge.

Duration Of Over 5000
When people see the expense of lithium batteries, they frequently turn away. But the duration of them is one of the most important considerations. A normal lead-acid battery can hold a charge for 200 900 . Daily solar charging can take up to many years under perfect circumstances and with adequate maintenance.
Lithium batteries, , have a known lifespan of more than 5,000 , or more than 10 years of operation.
Although initially more expensive, lithium batteries have a longer lifespan. One of the most economical options for creating a battery pack is choosing lithium batteries because they frequently dont need to be replaced.
No Battery Maintenance Vs Lead Acid
Given the sheer number of objects that require routine maintenance, it is clear why lithium batteries are a maintenance-free solution. Once you have inserted lithium cells in your battery pack, you can essentially forget about them.
, lead-acid batteries require a lot of regular maintenance. Sulfuric acid and water are used as an electrolyte in lead-acid batteries to aid in energy storage. Lead-acid batteries must be recharged frequently because the repeated charging and discharging might cause water to evaporate. Lead-acid batteries should be inspected and refilled regularly to avoid irreparable damage, decreased performance, and shortened battery life.
Even maintenance-free lead-acid batteries require periodicequalizedcharging to stay in good condition. Lithium batteries are the best substitute if you dont want to increase the number of maintenance tasks on your to-do list.

When Is A Lithium Ion Solar Battery The Best Choice
Lithium-ion solar batteries are the best solar energy storage system for everyday residential use because they take up little space while still storing a substantial amount of energy. Also, their high DoD means you can use more energy stored.
The battery will last longer, so it wont need to be replaced as often as a lead acid battery. Plus, their higher efficiency means that you get to use more of the energy your solar panels produce and store – giving you more bang for your buck.
However, in some cases, other battery types, like lead acid batteries, could work better for you. This is especially true if you are just using a solar battery as backup power storage. Since you wont be draining a backup battery regularly, the lower DoD and lifespan dont matter as much, so spending the extra money for those features wont be necessary.
Lead acid batteries are also popular for off-grid solar system projects that arent used regularly – like vacation cabins. But for everyday use, spending extra on a lithium-ion solar battery is probably your best bet.
Whether its for off-grid battery backup or for a grid-tied solar system, energy storage can help you run entirely on clean energy. Contact local solar installers to find the best solar battery system to pair with your solar panels.
