We note that despite the higher facial cost of Lithium technology, the cost per stored and supplied kWh remains much lower than for Lead-Acid technology. The reason is related to the intrinsic qualities of lithium-ion batteries but also linked to lower transportation costs.
Many think lithium batteries are more expensive than lead-acid ones for off-grid solar solutions. But is that really true? We use lithium batteries in all our solutions because of their performance, longevity, and lower cost. So let's do the math to see why this chemistry is the most cost-effective.
Here's why many people think lead-acid batteries are a better deal: You get ~20 kWh of capacity for around $5,000 with typical deep-cycle marine-grade or AGM lead-acid batteries, but say, only ~10 kWh for around $4,000 with high-quality lithium ones. But we must look beyond the nominal dollar per kWh. All batteries die.
In summary, the total cost of ownership per usable kWh is about 2.8 times cheaper for a lithium-based solution than for a lead acid solution. We note that despite the higher facial cost of Lithium technology, the cost per stored and supplied kWh remains much lower than for Lead-Acid technology.
Lead-acid batteries are suitable for short-term telecom solar setups with limited budgets. They are often used in legacy systems or for specific trials where low initial cost is a priority.
Meanwhile, a casual search on Amazon found a set of four 12V lead-acid batteries that combine to create a 6.8 kWh battery bank for $1,000. To build an 18 kWh pack, you''d pay $3,000
In summary, the total cost of ownership per usable kWh is about 2.8 times cheaper for a lithium-based solution than for a lead acid solution. We note that despite the higher facial cost of
