Which Solar Battery Has Bigger Storage Capacity Between Lead Acid Battery & Lithium- Ion Battery?

Solar batteries are a very important aspect of a solar system. These batteries can store electrical energy in the form of chemical energy and convert that energy into electricity. The Lead Acid Battery and the Lithium-Ion Battery are the two most common battery chemistry types. As their names imply, lithium-ion batteries are made with the metal lithium, while lead-acid batteries are made with lead. I bet you knew that already. Did you know that their chemistry differences have a great influence on their individual performance and cost?

Lead Acid Battery

An individual lead-acid battery will typically have a gross storage capacity of 100Ah - 200Ah @ 12V or 1.2kWh - 2.4kWh. They may be connected in series for a higher voltage and/or in parallel for greater capacity at the same voltage. A typical lead-acid pack suitable for a residential grid-backup solution will be in the range of 8kWh - 25kWh depending on the length of time required to operate off-grid and the total power of the loads to be supported.

Lithium-Ion Battery 

Lithium-Ion battery packs typically are supplied as self-contained units with a built-in battery management system (BMS). Gross capacities vary from about 2kWh up to 8 - 10kWh depending on the model and manufacturer. Some models may be connected in parallel; others may be extended with expansion packs and all need to be fully supported by the software in the battery charger/inverter chosen.

 

Conclusion? Lithium-Ion is currently the most sought after solar battery.

So Lithium-Ion it is!
