"Lead is dead" is more than just a catchy slogan; it's a declaration of a technological shift in residential and commercial energy storage systems.
For decades, lead-acid batteries have been the standard, but as we march into a more sustainable and efficient future, lithium batteries are rapidly becoming the preferred choice. The reason for this transition is multifaceted.
Lithium batteries offer a host of benefits, including superior energy density, greater depth of discharge, lower maintenance, greater sustainability, a longer lifespan, and lower cost per KWH.
When it comes to energy storage solutions for residential and commercial applications, it's safe to say the future belongs to lithium batteries. If you're looking for a reliable and efficient energy storage solution, consider making the switch to lithium technology. Let’s read more about Lithium batteries and their various benefits.
Lithium Batteries – Superior Energy Density
Lithium batteries offer superior energy density, meaning they can store more power in a smaller, lighter package - a crucial advantage in residential settings where space is often at a premium. Moreover, they boast a significantly longer lifespan and more robust chemistry compared to lead-acid batteries, reducing the frequency of replacements, and thereby cutting down long-term costs and inconvenience.
Lithium Batteries – Undiminished depth of discharge
Lithium batteries offer a higher depth of discharge without compromising their life expectancy, ensuring homeowners can utilize a greater percentage of their energy storage. The operational efficiency of lithium batteries is also higher, translating to less energy lost during charge and discharge cycles, which optimizes the energy harnessed from solar panels.
Lithium Batteries – Virtually Zero Maintenance and Increased Sustainability
The near-zero maintenance requirements of lithium batteries contrast sharply with the periodic upkeep needed for lead-acid batteries, offering a cleaner, safer, and more user-friendly product.
Lead-acid batteries require regular maintenance and lack of adequate maintenance is guaranteed to result in premature failure. There are also significant maintenance costs associated with the time, addition of distilled water, and specialized monitoring equipment.
Environmentally, lithium iron phosphate batteries outshine lead-acid as well, with no hazardous acid or lead content, making them a more sustainable and eco-friendly option.
Lithium Batteries – Cost per KWH and Lifespan
Now let’s show you how lithium batteries are not just a purchase, but a smart investment for the future. We'll talk numbers in terms of cost per usable kilowatt-hour (kWh). It is important to note that traditionally lead acid batteries have 50% usable energy per unit compared to lithium batteries with as much as 80-100% usable energy. On average, quality lithium batteries cost about $350-500 per usable kWh and the price is falling. In comparison, a quality flooded lead-acid battery costs around $300-340 per usable kWh, and a quality AGM battery falls in the range of $450-670 per usable kWh and the cost continues to go up and up as lead commodity prices increase. These cost/kWh are reasonable examples, in some cases cost may be less and in some cases more, these values are simple observations concerning unit cost compared to usable energy based on the note above. Considering the lifespan, an AGM battery typically lasts about 3-5 years with heavy usage, a flooded lead acid battery may be slightly longer, while a lithium battery can easily last 10 years or more with heavy usage. This difference in longevity is crucial. Over 10 years, you may need to replace lead acid batteries 2-3 times, effectively doubling or tripling the evaluated cost. Therefore, the total cost for lead acid batteries will easily exceed that of lithium batteries if it doesn’t already do so upfront.
All these factors coalesce into the undeniable reality that in the realm of residential energy storage, "lead is dead," and the future shines brightly on the side of lithium technology.
Lithium Battery Conclusions:
Lithium batteries have a higher energy density and are more efficient in both charging and discharging. You get more usable energy per charge, reducing your energy storage needs and costs over time. Maintenance is another area where lithium batteries shine. We have surpassed the point where the Total Cost of Ownership (TCO) for lead acid batteries is cheaper than lithium. Especially when including replacement and maintenance.
By choosing lithium, you're not only saving money but also investing in the sustainability and efficiency of your solar system. While lead acid batteries may still have a use for specific applications, it’s pretty safe to say that LEAD IS DEAD as it relates to residential and commercial ESS projects.
