Comparison Between the Lead-Acid Battery and Lithium Battery Pack Installed with a Solar Set-Up

 There are various batteries to pick from if you're thinking about home energy storage. In this post, we'll contrast lead-acid and lithium battery pack are two of the most popular battery types used with solar setups.

The primary distinction between each type of battery is in terms of price and performance, aside from the various materials that make up each type of battery. Lithium-ion batteries perform better and are more effective, although lead-acid batteries are typically less expensive.

Battery storage is becoming a more popular component of solar energy systems. Lithium-ion and lead-acid are two of the most common battery chemistry types.

The lithium battery packs as the name implies, are made of the metal lithium, whereas lead-acid batteries are made of lead. Battery storage is becoming a more popular component of solar energy systems.

Comparison between the lead-acid battery and lithium-ion battery

Both lithium-ion and lead-acid batteries can effectively store energy, but each has distinct advantages and disadvantages. Here are some key comparison points to keep in mind when selecting a battery type:

1. Cost of the batteries

The one area where lead acid batteries appear to outperform lithium battery pack options is cost. A lead acid battery system may cost hundreds or thousands of dollars less than a comparable-sized lithium-ion setup.

Lithium battery packs currently cost anywhere from $5,000 to $15,000 including installation, and this range can vary depending on the size of the system you require.

While lead-acid batteries are typically less expensive to purchase and install than lithium-ion batteries, the lifetime value of a lithium-ion battery balances the scales.

2. Capacity of batteries

The capacity of a battery is a measure of how much energy it can store (and eventually discharge). While capacity numbers vary depending on the battery model and manufacturer, lithium battery pack technology has been shown to have significantly higher energy density than lead-acid batteries.

This means that a lithium-ion battery can store more energy in the same physical space. Because lithium-ion technology can store more energy, it can discharge more energy, allowing you to power more appliances for longer periods.

3. Longevity of the battery

Batteries, like solar panels, degrade over time and become less effective as they get older. One "cycle" is defined as discharging a battery to power your home or appliances and then recharging it with solar energy or the grid.

The numbers vary by study, but lithium battery pack typically last several times as long as lead acid batteries, resulting in a longer effective lifespan for lithium battery products.

4. Cost of maintenance

The cost of maintaining the lead-acid battery is almost the same as purchasing a new one compared to a lithium battery pack. So, before you purchase any of the batteries, consider the difference and choose based on what it's needed for.
